Any web developer doing the same will have noticed the increase in traffic from mobile devices of late. Over the past year we’ve seen many key sites garner a significant percentage of pageviews from smartphones and tablets. These represent large numbers of visitors, with sophisticated browsers which support the latest HTML, CSS, and JavaScript, but which also have limited screen space with widths as narrow as 320 pixels. <br /> <br /> Our commitment to <a href="//www.google.com/accessibility/">accessibility</a> means we strive to provide a good browsing experience for all our users. We faced a stark choice between creating mobile specific websites, or adapting existing sites and new launches to render well on both desktop and mobile. Creating two sites would allow us to better target specific hardware, but maintaining a single shared site preserves a canonical URL, avoiding any complicated redirects, and simplifies the sharing of web addresses. With a mind towards maintainability we leant towards using the same pages for both, and started thinking about how we could fulfill the following guidelines: <br /> <ol> <li><b>Our pages should render legibly at any screen resolution</b></li> <li><b>We mark up one set of content, making it viewable on any device</b></li> <li><b>We should never show a horizontal scrollbar, whatever the window size</b></li> </ol> <br /> <div class="separator" style="clear: both; text-align: center;"> <a href="//2.bp.blogspot.com/-JPZfFJzcakc/T58dQHAeD_I/AAAAAAAAK8c/qNszHAhR2Ek/s1600/responsive_chrome.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img height="390" src="//2.bp.blogspot.com/-JPZfFJzcakc/T58dQHAeD_I/AAAAAAAAK8c/qNszHAhR2Ek/s400/responsive_chrome.jpg" style="border: 0 !important;" width="400"></a></div> <br /> <i style="display: block; margin: 0px auto 10px; text-align: center;">Stacked content, tweaked navigation and rescaled images – <a href="//www.google.com/intl/en/chrome/devices/features.html">Chromebooks</a></i> <br /> <div style="font-size: 16px; font-weight: bold;"> Implementation</div> <br /> As a starting point, simple, semantic markup gives us pages which are more flexible and easier to reflow if the layout needs to be changed. By ensuring the stylesheet enables a <a href="http://www.alistapart.com/articles/responsive-web-design/">liquid layout</a>, we're already on the road to mobile-friendliness. Instead of specifying <code>width</code> for container elements, we started using <code>max-width</code> instead. In place of <code>height</code> we used <code>min-height</code>, so larger fonts or multi-line text don’t break the container’s boundaries. To prevent fixed width images “propping open” liquid columns, we apply the following CSS rule:<br /> <br /> <pre><code>img { max-width: 100%; }</code></pre> <br /> <br /> Liquid layout is a good start, but can lack a certain finesse. Thankfully <a href="http://www.w3.org/TR/css3-mediaqueries/">media queries</a> are now <a href="http://www.caniuse.com/#search=media+queries">well-supported in modern browsers</a> including IE9+ and most mobile devices. These can make the difference between a site that degrades well on a mobile browser, vs. one that is enhanced to take advantage of the streamlined UI. But first we have to take into account how smartphones represent themselves to web servers.<br /> <br /> <div style="font-size: 16px; font-weight: bold;"> Viewports</div> <br /> When is a pixel not a pixel? When it’s on a smartphone. By default, smartphone browsers pretend to be high-resolution desktop browsers, and lay out a page as if you were viewing it on a desktop monitor. This is why you get a tiny-text “overview mode” that’s impossible to read before zooming in. The <a href="http://developer.android.com/guide/webapps/targeting.html">default viewport width</a> for the default Android browser is 800px, and 980px for iOS, regardless of the number of <a href="http://en.wikipedia.org/wiki/List_of_displays_by_pixel_density">actual physical pixels</a> on the screen. <br /> <br /> In order to trigger the browser to render your page at a more readable scale, you need to use the viewport meta element: <br /> <pre><code> <meta name="viewport" content="width=device-width, initial-scale=1"> </code></pre> <br /> <br /> Mobile screen resolutions vary widely, but most modern smartphone browsers currently report a standard <code>device-width</code> in the region of 320px. If your mobile device actually has a width of 640 physical pixels, then a 320px wide image would be sized to the full width of the screen, using double the number of pixels in the process. This is also the reason why text looks so much crisper on the small screen – double the pixel density as compared to a standard desktop monitor. <br /> <br /> The useful thing about setting the <code>width</code> to <code>device-width</code> in the viewport meta tag is that it updates when the user changes the orientation of their smartphone or tablet. Combining this with media queries allows you to tweak the layout as the user rotates their device: <br /> <pre><code> @media screen and (min-width:480px) and (max-width:800px) {   /* Target landscape smartphones, portrait tablets, narrow desktops   */ } @media screen and (max-width:479px) {   /* Target portrait smartphones */ } </code></pre> <br /> <br /> In reality you may find you need to use different breakpoints depending on how your site flows and looks on various devices. You can also use the <code>orientation</code> media query to target specific orientations without referencing pixel dimensions, <a href="http://caniuse.com/#search=orientation">where supported</a>. <br /> <br /> <pre><code> @media all and (orientation: landscape) {   /* Target device in landscape mode */ } @media all and (orientation: portrait) {   /* Target device in portrait mode */ }</code></pre> <br /> <br /> <div class="separator" style="clear: both; text-align: center;"> <a href="//4.bp.blogspot.com/-dYbonxwoqWU/T58dTMFtthI/AAAAAAAAK8s/54oaQ2VoDg8/s1600/responsive_cultural.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img height="400" src="//4.bp.blogspot.com/-dYbonxwoqWU/T58dTMFtthI/AAAAAAAAK8s/54oaQ2VoDg8/s400/responsive_cultural.jpg" style="border: 0 !important;" width="381"></a></div> <br /> <i style="display: block; margin: 0px auto 10px; text-align: center;">Stacked content, smaller images – <a href="//www.google.com/culturalinstitute">Cultural Institute</a></i> <br /> <div style="font-size: 16px; font-weight: bold;"> A media queries example</div> <br /> We recently re-launched the <a href="//www.google.com/about/">About Google</a> page. Apart from setting up a liquid layout, we added a few media queries to provide an improved experience on smaller screens, like those on a tablet or smartphone. <br /> <br /> Instead of targeting specific device resolutions we went with a relatively broad set of breakpoints. For a screen resolution wider than 1024 pixels, we render the page as it was originally designed, according to our 12-column grid. Between 801px and 1024px, you get to see a slightly squished version thanks to the liquid layout. <br /> <br /> Only if the screen resolution drops to 800 pixels will content that’s not considered core content be sent to the bottom of the page: <br /> <br /> <pre><code> @media screen and (max-width: 800px) { /* specific CSS */ } </code></pre> <br /> <br /> With a final media query we enter smartphone territory: <br /> <br /> <pre><code> @media screen and (max-width: 479px) { /* specific CSS */ } </code></pre> <br /> <br /> At this point, we’re not loading the large image anymore and we stack the content blocks. We also added additional whitespace between the content items so they are more easily identified as different sections. <br /> <br /> With these simple measures we made sure the site is usable on a wide range of devices. <br /> <br /> <div class="separator" style="clear: both; text-align: center;"> <a href="//1.bp.blogspot.com/-PU9-y7MJB_U/T58dS0jUfWI/AAAAAAAAK8k/Niann_r6Wjg/s1600/responsive_about.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img height="400" src="//1.bp.blogspot.com/-PU9-y7MJB_U/T58dS0jUfWI/AAAAAAAAK8k/Niann_r6Wjg/s400/responsive_about.jpg" style="border: 0 !important;" width="396"></a></div> <br /> <i style="display: block; margin: 0px auto 10px; text-align: center;">Stacked content and the removal of large image – <a href="//www.google.com/about/">About Google</a></i> <br /> <div style="font-size: 16px; font-weight: bold;"> Conclusion</div> <br /> It’s worth bearing in mind that there’s no simple solution to making sites accessible on mobile devices and narrow viewports. Liquid layouts are a great starting point, but some design compromises may need to be made.

And if you have a fancy widget on your site, it might work beautifully with a mouse, but not so great on a touch device where fine control is more difficult. <br /> <br /> The key is to test early and test often. Any time spent surfing your own sites with a smartphone or tablet will prove invaluable. When you can’t test on real devices, use the <a href="http://developer.android.com/sdk/index.html">Android SDK</a> or <a href="http://developer.apple.com/devcenter/ios/index.action">iOS Simulator</a>. Ask friends and colleagues to view your sites on their devices, and watch how they interact too. <br /> <br /> Mobile browsers are a great source of new traffic, and learning how best to support them is an exciting new area of professional development. <br /> <br /> Some more examples of responsive design at Google: <br /> <ul> <li><a href="//www.google.com/about/">www.google.com/about/</a></li> <li><a href="//www.google.com/goodtoknow">www.google.com/goodtoknow</a></li> <li><a href="//www.google.com/culturalinstitute">www.google.com/culturalinstitute</a></li> <li><a href="//www.google.com/events/sciencefair">www.google.com/events/sciencefair</a></li> <li><a href="//www.google.com/intl/en/chrome/devices">www.google.com/intl/en/chrome/devices</a></li> <li><a href="http://picasa.google.com/">picasa.google.com</a></li> </ul> <br /> <br /> <span class="byline-author">Written by <a href="https://plus.google.com/111296156124188875659/about" rel="author">Rupert Breheny</a>, <a href="https://plus.google.com/114073068697999578001/about" rel="author">Edward Jung</a>, & <a href="https://plus.google.com/101131853496921328128/about" rel="author">Matt Zürrer</a>, Google Webmaster Team</span></div> <span itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://plus.google.com/116899029375914044550' itemprop='url'/> </span> </script> <noscript> <div dir="ltr" style="text-align: left;" trbidi="on"> <span style="color: #666666;">Webmaster Level: Intermediate / Advanced</span> <br /> <br /> We love data, and spend a lot of time monitoring the analytics on our websites.

If we find the URL leads to an image, we’ll usually revisit with Googlebot-Image. Because of this, it’s generally a good idea to allow crawling of your images and pages by both Googlebot and Googlebot-Image.<br /> <br /> <b>Q:</b> Is it true that there’s a maximum file size for the images?<br /> <b>A:</b> We’re happy to index images of any size; there’s no file size restriction. <br /> <br /> <div class="separator" style="clear: both; text-align: center;"> </div> <div class="separator" style="clear: both; text-align: center;"> <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjT6VPatY9ba_AXj13XC1kZ6f1fM1q54X6eThEdz_QVkfsRn18BiuEFAyLowmr332Ppp7v_r3TwAoymgQtV8Kj6tbaZd_p8A30gVQlEpgO_2W8fnm74zAEUBY8CQFXUvSjerYi9/s1600/blog_exif.png" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" data-original-height="251" data-original-width="268" height="299" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjT6VPatY9ba_AXj13XC1kZ6f1fM1q54X6eThEdz_QVkfsRn18BiuEFAyLowmr332Ppp7v_r3TwAoymgQtV8Kj6tbaZd_p8A30gVQlEpgO_2W8fnm74zAEUBY8CQFXUvSjerYi9/s320/blog_exif.png" width="320" /></a></div> <b>Q:</b> What happens to the EXIF, XMP and other metadata my images contain?<br /> <b>A:</b> We may use any information we find to help our users find what they’re looking for more easily. Additionally, information like EXIF data may be displayed in the right-hand sidebar of the interstitial page that appears when you click on an image.<br /> <b><br /></b> <b>Q:</b> Should I really submit an Image Sitemap? What are the benefits?<br /> <b>A:</b> Yes! <a href="http://support.google.com/webmasters/bin/answer.py?answer=178636">Image Sitemaps</a> help us learn about your new images and may also help us learn what the images are about.<br /> <b><br /></b> <b>Q:</b> I’m using a CDN to host my images; how can I still use an Image Sitemap?<br /> <b>A:</b> <a href="http://www.sitemaps.org/protocol.html#sitemaps_cross_submits">Cross-domain restrictions</a> apply only to the Sitemaps’ <loc> tag. In Image Sitemaps, the <image:loc> tag is allowed to point to a URL on another domain, so using a CDN for your images is fine. We also encourage you to verify the CDN’s domain name in Webmaster Tools so that we can inform you of any crawl errors that we might find.</image:loc></loc><br /> <loc><image:loc><b><br /></b></image:loc></loc> <loc><image:loc><b>Q:</b> Is it a problem if my images can be found on multiple domains or subdomains I own — for example, CDNs or related sites?</image:loc></loc><br /> <loc><image:loc><b>A:</b> Generally, the best practice is to have only one copy of any type of content. If you’re duplicating your images across multiple hostnames, our algorithms may pick one copy as the canonical copy of the image, which may not be your preferred version. This can also lead to slower crawling and indexing of your images.</image:loc></loc><br /> <loc><image:loc><b><br /></b></image:loc></loc> <loc><image:loc><b>Q:</b> We sometimes see the original source of an image ranked lower than other sources; why is this?</image:loc></loc><br /> <loc><image:loc><b>A:</b> Keep in mind that we use the textual content of a page when determining the context of an image. For example, if the original source is a page from an image gallery that has very little text, it can happen that a page with more textual context is chosen to be shown in search. If you feel you've identified very bad search results for a particular query, feel free to use the feedback link below the search results or to share your example in our <a href="//g.co/webmasterhelpforum">Webmaster Help Forum</a>. </image:loc></loc><br /> <h3> SafeSearch</h3> Our algorithms use a great variety of signals to decide whether an image — or a whole page, if we’re talking about Web Search — should be filtered from the results when the user’s SafeSearch filter is turned on. In the case of images some of these signals are generated using computer vision, but the SafeSearch algorithms also look at simpler things such as where the image was used previously and the context in which the image was used.<br /> <div> One of the strongest signals, however, is self-marked adult pages. We recommend that webmasters who publish adult content mark up their pages with one of the following meta tags: <br /> <pre><meta name="rating" content="adult" /> <meta name="rating" content="RTA-5042-1996-1400-1577-RTA" /> </pre> Many users prefer not to have adult content included in their search results (especially if kids use the same computer). When a webmaster provides one of these meta tags, it helps to provide a better user experience because users don't see results which they don't want to or expect to see. </div> <div> <br /></div> <div> As with all algorithms, sometimes it may happen that SafeSearch filters content inadvertently. If you think your images or pages are mistakenly being filtered by SafeSearch, please let us know in the <a href="//g.co/webmasterhelpforum">Webmaster Help Forum</a>. </div> <div> <br /></div> <div> If you need more information about how we index images, please check out the section of our Help Center dedicated to <a href="http://support.google.com/webmasters/bin/topic.py?topic=2370565">images</a>, read our <a href="//www.google.com/webmasters/docs/search-engine-optimization-starter-guide.pdf">SEO Starter Guide</a> which contains lots of useful information, and if you have more questions please post them in the <a href="//g.co/webmasterhelpforum">Webmaster Help Forum</a>. </div> <div> <br /></div> <div> <span class="byline-author">Written by <a href="https://twitter.com/methode" rel="author">Gary Illyes</a>, Webmaster Trends Analyst</span></div> </div> <span itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://plus.google.com/116899029375914044550' itemprop='url'/> </span> </script> <noscript> <div dir="ltr" style="text-align: left;" trbidi="on"> Webmaster level: All<br /> <br /> Creativity is an important aspect of our lives and can enrich nearly everything we do.

Because of this, it’s generally a good idea to allow crawling of your images and pages by both Googlebot and Googlebot-Image.<br /> <br /> <b>Q:</b> Is it true that there’s a maximum file size for the images?<br /> <b>A:</b> We’re happy to index images of any size; there’s no file size restriction. <br /> <br /> <div class="separator" style="clear: both; text-align: center;"> </div> <div class="separator" style="clear: both; text-align: center;"> <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjT6VPatY9ba_AXj13XC1kZ6f1fM1q54X6eThEdz_QVkfsRn18BiuEFAyLowmr332Ppp7v_r3TwAoymgQtV8Kj6tbaZd_p8A30gVQlEpgO_2W8fnm74zAEUBY8CQFXUvSjerYi9/s1600/blog_exif.png" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" data-original-height="251" data-original-width="268" height="299" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjT6VPatY9ba_AXj13XC1kZ6f1fM1q54X6eThEdz_QVkfsRn18BiuEFAyLowmr332Ppp7v_r3TwAoymgQtV8Kj6tbaZd_p8A30gVQlEpgO_2W8fnm74zAEUBY8CQFXUvSjerYi9/s320/blog_exif.png" width="320" /></a></div> <b>Q:</b> What happens to the EXIF, XMP and other metadata my images contain?<br /> <b>A:</b> We may use any information we find to help our users find what they’re looking for more easily. Additionally, information like EXIF data may be displayed in the right-hand sidebar of the interstitial page that appears when you click on an image.<br /> <b><br /></b> <b>Q:</b> Should I really submit an Image Sitemap? What are the benefits?<br /> <b>A:</b> Yes! <a href="http://support.google.com/webmasters/bin/answer.py?answer=178636">Image Sitemaps</a> help us learn about your new images and may also help us learn what the images are about.<br /> <b><br /></b> <b>Q:</b> I’m using a CDN to host my images; how can I still use an Image Sitemap?<br /> <b>A:</b> <a href="http://www.sitemaps.org/protocol.html#sitemaps_cross_submits">Cross-domain restrictions</a> apply only to the Sitemaps’ <loc> tag. In Image Sitemaps, the <image:loc> tag is allowed to point to a URL on another domain, so using a CDN for your images is fine. We also encourage you to verify the CDN’s domain name in Webmaster Tools so that we can inform you of any crawl errors that we might find.</image:loc></loc><br /> <loc><image:loc><b><br /></b></image:loc></loc> <loc><image:loc><b>Q:</b> Is it a problem if my images can be found on multiple domains or subdomains I own — for example, CDNs or related sites?</image:loc></loc><br /> <loc><image:loc><b>A:</b> Generally, the best practice is to have only one copy of any type of content. If you’re duplicating your images across multiple hostnames, our algorithms may pick one copy as the canonical copy of the image, which may not be your preferred version. This can also lead to slower crawling and indexing of your images.</image:loc></loc><br /> <loc><image:loc><b><br /></b></image:loc></loc> <loc><image:loc><b>Q:</b> We sometimes see the original source of an image ranked lower than other sources; why is this?</image:loc></loc><br /> <loc><image:loc><b>A:</b> Keep in mind that we use the textual content of a page when determining the context of an image. For example, if the original source is a page from an image gallery that has very little text, it can happen that a page with more textual context is chosen to be shown in search. If you feel you've identified very bad search results for a particular query, feel free to use the feedback link below the search results or to share your example in our <a href="//g.co/webmasterhelpforum">Webmaster Help Forum</a>. </image:loc></loc><br /> <h3> SafeSearch</h3> Our algorithms use a great variety of signals to decide whether an image — or a whole page, if we’re talking about Web Search — should be filtered from the results when the user’s SafeSearch filter is turned on. In the case of images some of these signals are generated using computer vision, but the SafeSearch algorithms also look at simpler things such as where the image was used previously and the context in which the image was used.<br /> <div> One of the strongest signals, however, is self-marked adult pages. We recommend that webmasters who publish adult content mark up their pages with one of the following meta tags: <br /> <pre><meta name="rating" content="adult" /> <meta name="rating" content="RTA-5042-1996-1400-1577-RTA" /> </pre> Many users prefer not to have adult content included in their search results (especially if kids use the same computer). When a webmaster provides one of these meta tags, it helps to provide a better user experience because users don't see results which they don't want to or expect to see. </div> <div> <br /></div> <div> As with all algorithms, sometimes it may happen that SafeSearch filters content inadvertently. If you think your images or pages are mistakenly being filtered by SafeSearch, please let us know in the <a href="//g.co/webmasterhelpforum">Webmaster Help Forum</a>. </div> <div> <br /></div> <div> If you need more information about how we index images, please check out the section of our Help Center dedicated to <a href="http://support.google.com/webmasters/bin/topic.py?topic=2370565">images</a>, read our <a href="//www.google.com/webmasters/docs/search-engine-optimization-starter-guide.pdf">SEO Starter Guide</a> which contains lots of useful information, and if you have more questions please post them in the <a href="//g.co/webmasterhelpforum">Webmaster Help Forum</a>. </div> <div> <br /></div> <div> <span class="byline-author">Written by <a href="https://twitter.com/methode" rel="author">Gary Illyes</a>, Webmaster Trends Analyst</span></div> </div> <span itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://plus.google.com/116899029375914044550' itemprop='url'/> </span> </noscript> </div> </div> <div class='share'> <span class='twitter-custom social-wrapper' data-href='http://twitter.com/share?text=Official Google Webmaster Central Blog:1000 Words About Images&url=https://webmasters.googleblog.com/2012/04/1000-words-about-images.html?hl=en&via=googlewmc'> <img alt='Share on Twitter' height='24' src='https://www.gstatic.com/images/icons/material/system/2x/post_twitter_black_24dp.png' width='24'/> </span> <span class='fb-custom social-wrapper' data-href='https://www.facebook.com/sharer.php?u=https://webmasters.googleblog.com/2012/04/1000-words-about-images.html?hl=en'> <img alt='Share on Facebook' height='24' src='https://www.gstatic.com/images/icons/material/system/2x/post_facebook_black_24dp.png' width='24'/> </span> </div> <div class='post-footer'> <div class='cmt_iframe_holder' data-href='https://webmasters.googleblog.com/2012/04/1000-words-about-images.html' data-viewtype='FILTERED_POSTMOD'></div> <a href='https://plus.google.com/112374322230920073195' rel='author' style='display:none;'> Google </a> <div class='label-footer'> <span class='labels-caption'> Labels: </span> <span class='labels'> <a class='label' href='https://webmasters.googleblog.com/search/label/crawling%20and%20indexing?hl=en' rel='tag'> crawling and indexing </a> , <a class='label' href='https://webmasters.googleblog.com/search/label/general%20tips?hl=en' rel='tag'> general tips </a> , <a class='label' href='https://webmasters.googleblog.com/search/label/images?hl=en' rel='tag'> images </a> </span> </div> </div> </div> <div class='post' data-id='237718932378532213' itemscope='' itemtype='http://schema.org/BlogPosting'> <h2 class='title' itemprop='name'> <a href='https://webmasters.googleblog.com/2012/04/how-to-move-your-content-to-new.html?hl=en' itemprop='url' title='How to move your content to a new location'> How to move your content to a new location </a> </h2> <div class='post-header'> <div class='published'> <span class='publishdate' itemprop='datePublished'> Tuesday, April 24, 2012 </span> </div> </div> <div class='post-body'> <div class='post-content' itemprop='articleBody'> <script type='text/template'> <div dir="ltr" style="text-align: left;" trbidi="on"> Webmaster level: Intermediate<br /> <br /> While maintaining a website, webmasters may decide to move the whole website or parts of it to a new location.

In the pursuit of higher rankings or traffic, a few sites use techniques that don’t benefit users, where the intent is to look for shortcuts or loopholes that would rank pages higher than they deserve to be ranked. We see all sorts of webspam techniques every day, from <a href="http://support.google.com/webmasters/bin/answer.py?hl=en&answer=66358">keyword stuffing</a> to <a href="http://support.google.com/webmasters/bin/answer.py?hl=en&answer=66356">link schemes</a> that attempt to propel sites higher in rankings.<br /> <br /> The goal of many of our ranking changes is to help searchers find sites that provide a great user experience and fulfill their information needs. We also want the “good guys” making great sites for users, not just algorithms, to see their effort rewarded. To that end we’ve launched <a href="http://googleblog.blogspot.com/2011/02/finding-more-high-quality-sites-in.html">Panda changes</a> that successfully <a href="http://www.newscientist.com/article/mg21228436.200-inside-search-engines-war-on-bad-results.html">returned higher-quality sites in search results</a>. And earlier this year we launched a <a href="http://insidesearch.blogspot.com/2012/01/page-layout-algorithm-improvement.html">page layout algorithm</a> that reduces rankings for sites that don’t make much content available “above the fold.”<br /> <br /> In the next few days, we’re launching an important algorithm change targeted at webspam. The change will decrease rankings for sites that we believe are violating Google’s existing <a href="http://support.google.com/webmasters/bin/answer.py?hl=en&answer=35769#3">quality guidelines</a>. We’ve always targeted webspam in our rankings, and this algorithm represents another improvement in our efforts to reduce webspam and promote high quality content. While we can't divulge specific signals because we don't want to give people a way to game our search results and worsen the experience for users, our advice for webmasters is to focus on <a href="http://googlewebmastercentral.blogspot.com/2011/05/more-guidance-on-building-high-quality.html">creating high quality sites</a> that create a good user experience and employ white hat SEO methods instead of engaging in aggressive webspam tactics.<br /> <br /> Here’s an example of a webspam tactic like keyword stuffing taken from a site that will be affected by this change: <br /> <br /> <div class="separator" style="clear: both; text-align: center;"> <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhJKSXgQN0A4-Pht-F7jsZtzSsgPYvEvPqvKL-t686twukXe4Lway7nTfpvzH9kyjoZEDXrnZzq3Tdx2-HxK9JEth3SvSWPoWbaZH-kAjl8Cq1xICMKEUmhQH6OpN8NGv-4-r6u/s1600/keyword-stuffing.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="199" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhJKSXgQN0A4-Pht-F7jsZtzSsgPYvEvPqvKL-t686twukXe4Lway7nTfpvzH9kyjoZEDXrnZzq3Tdx2-HxK9JEth3SvSWPoWbaZH-kAjl8Cq1xICMKEUmhQH6OpN8NGv-4-r6u/s320/keyword-stuffing.png" width="320" /></a></div> <br /> Of course, most sites affected by this change aren’t so blatant. Here’s an example of a site with unusual linking patterns that is also affected by this change. Notice that if you try to read the text aloud you’ll discover that the outgoing links are completely unrelated to the actual content, and in fact the page text has been “spun” beyond recognition: <br /> <br /> <div class="separator" style="clear: both; text-align: center;"> <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhChsb3OfR2YlcYJEhuMLov4oNIYsUaMrT8B66PF028qI5o1g7Zjcl-O_AtzlPwdBH5vawZONZIfu8zW1m_VY74_cOWTVHeKjpr5JAxeroeqjWYsKNSuOB-QBkiw2ju2u6ElFST/s1600/link-spam.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="212" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhChsb3OfR2YlcYJEhuMLov4oNIYsUaMrT8B66PF028qI5o1g7Zjcl-O_AtzlPwdBH5vawZONZIfu8zW1m_VY74_cOWTVHeKjpr5JAxeroeqjWYsKNSuOB-QBkiw2ju2u6ElFST/s320/link-spam.png" width="320" /></a></div> <br /> Sites affected by this change might not be easily recognizable as spamming without deep analysis or expertise, but the common thread is that these sites are doing much more than white hat SEO; we believe they are engaging in webspam tactics to manipulate search engine rankings.<br /> <br /> The change will go live for all languages at the same time. For context, the initial Panda change affected about 12% of queries to a significant degree; this algorithm affects about 3.1% of queries in English to a degree that a regular user might notice. The change affects roughly 3% of queries in languages such as German, Chinese, and Arabic, but the impact is higher in more heavily-spammed languages. For example, 5% of Polish queries change to a degree that a regular user might notice.<br /> <br /> We want people doing white hat search engine optimization (or even no search engine optimization at all) to be free to focus on creating amazing, compelling web sites. As always, we’ll keep our ears open for feedback on ways to iterate and improve our ranking algorithms toward that goal.<br /> <br /> <span class="byline-author">Posted by <a href="https://plus.google.com/109412257237874861202/about" rel="author">Matt Cutts</a>, Distinguished Engineer</span></div> <span itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://plus.google.com/116899029375914044550' itemprop='url'/> </span> </script> <noscript> <div dir="ltr" style="text-align: left;" trbidi="on"> Webmaster level: All<br /> <br /> Google has said before that search engine optimization, or SEO, can be <a href="//www.youtube.com/watch?v=BS75vhGO-kk">positive and constructive</a>—and we're <a href="http://www.bing.com/community/site_blogs/b/webmaster/archive/2012/03/23/does-bing-like-seo-you-bet-your-ahrefs-we-do.aspx">not the only ones</a>.

Notice that if you try to read the text aloud you’ll discover that the outgoing links are completely unrelated to the actual content, and in fact the page text has been “spun” beyond recognition: <br /> <br /> <div class="separator" style="clear: both; text-align: center;"> <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhChsb3OfR2YlcYJEhuMLov4oNIYsUaMrT8B66PF028qI5o1g7Zjcl-O_AtzlPwdBH5vawZONZIfu8zW1m_VY74_cOWTVHeKjpr5JAxeroeqjWYsKNSuOB-QBkiw2ju2u6ElFST/s1600/link-spam.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="212" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhChsb3OfR2YlcYJEhuMLov4oNIYsUaMrT8B66PF028qI5o1g7Zjcl-O_AtzlPwdBH5vawZONZIfu8zW1m_VY74_cOWTVHeKjpr5JAxeroeqjWYsKNSuOB-QBkiw2ju2u6ElFST/s320/link-spam.png" width="320" /></a></div> <br /> Sites affected by this change might not be easily recognizable as spamming without deep analysis or expertise, but the common thread is that these sites are doing much more than white hat SEO; we believe they are engaging in webspam tactics to manipulate search engine rankings.<br /> <br /> The change will go live for all languages at the same time. For context, the initial Panda change affected about 12% of queries to a significant degree; this algorithm affects about 3.1% of queries in English to a degree that a regular user might notice. The change affects roughly 3% of queries in languages such as German, Chinese, and Arabic, but the impact is higher in more heavily-spammed languages. For example, 5% of Polish queries change to a degree that a regular user might notice.<br /> <br /> We want people doing white hat search engine optimization (or even no search engine optimization at all) to be free to focus on creating amazing, compelling web sites. As always, we’ll keep our ears open for feedback on ways to iterate and improve our ranking algorithms toward that goal.<br /> <br /> <span class="byline-author">Posted by <a href="https://plus.google.com/109412257237874861202/about" rel="author">Matt Cutts</a>, Distinguished Engineer</span></div> <span itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://plus.google.com/116899029375914044550' itemprop='url'/> </span> </noscript> </div> </div> <div class='share'> <span class='twitter-custom social-wrapper' data-href='http://twitter.com/share?text=Official Google Webmaster Central Blog:Another step to reward high-quality sites&url=https://webmasters.googleblog.com/2012/04/another-step-to-reward-high-quality.html?hl=en&via=googlewmc'> <img alt='Share on Twitter' height='24' src='https://www.gstatic.com/images/icons/material/system/2x/post_twitter_black_24dp.png' width='24'/> </span> <span class='fb-custom social-wrapper' data-href='https://www.facebook.com/sharer.php?u=https://webmasters.googleblog.com/2012/04/another-step-to-reward-high-quality.html?hl=en'> <img alt='Share on Facebook' height='24' src='https://www.gstatic.com/images/icons/material/system/2x/post_facebook_black_24dp.png' width='24'/> </span> </div> <div class='post-footer'> <div class='cmt_iframe_holder' data-href='https://webmasters.googleblog.com/2012/04/another-step-to-reward-high-quality.html' data-viewtype='FILTERED_POSTMOD'></div> <a href='https://plus.google.com/112374322230920073195' rel='author' style='display:none;'> Google </a> <div class='label-footer'> <span class='labels-caption'> Labels: </span> <span class='labels'> <a class='label' href='https://webmasters.googleblog.com/search/label/advanced?hl=en' rel='tag'> advanced </a> , <a class='label' href='https://webmasters.googleblog.com/search/label/beginner?hl=en' rel='tag'> beginner </a> , <a class='label' href='https://webmasters.googleblog.com/search/label/intermediate?hl=en' rel='tag'> intermediate </a> , <a class='label' href='https://webmasters.googleblog.com/search/label/search%20results?hl=en' rel='tag'> search results </a> </span> </div> </div> </div> <div class='post' data-id='1603440325559343712' itemscope='' itemtype='http://schema.org/BlogPosting'> <h2 class='title' itemprop='name'> <a href='https://webmasters.googleblog.com/2012/04/updates-to-rich-snippets.html?hl=en' itemprop='url' title='Updates to rich snippets'> Updates to rich snippets </a> </h2> <div class='post-header'> <div class='published'> <span class='publishdate' itemprop='datePublished'> Monday, April 16, 2012 </span> </div> </div> <div class='post-body'> <div class='post-content' itemprop='articleBody'> <script type='text/template'> <div dir="ltr" style="text-align: left;" trbidi="on"> <b id="internal-source-marker_0.575230079004541" style="font-family: inherit;"><span style="font-weight: normal; vertical-align: baseline; white-space: pre-wrap;">Webmaster level: All</span></b> <b style="font-family: inherit;"><span style="font-weight: normal; vertical-align: baseline; white-space: pre-wrap;"><br /></span></b><br /> <b style="font-family: inherit;"><span style="font-weight: normal; vertical-align: baseline; white-space: pre-wrap;">Today we’re announcing two updates to </span></b><a href="http://support.google.com/webmasters/bin/answer.py?hl=en&answer=99170" style="font-family: inherit;"><span style="color: #1155cc; vertical-align: baseline; white-space: pre-wrap;">rich snippets</span></a><span style="font-family: inherit; vertical-align: baseline; white-space: pre-wrap;">.</span><br /> <br /> <span style="font-family: inherit;"><span class=""><span id="internal-source-marker_0.575230079004541"><span style="font-weight: normal; vertical-align: baseline; white-space: pre-wrap;">First, we’re happy to announce that </span></span><a href="http://support.google.com/webmasters/bin/answer.py?hl=en&answer=146750" style="font-weight: bold;"><span style="color: #1155cc; font-weight: normal; vertical-align: baseline; white-space: pre-wrap;">product rich snippets</span></a><span style="font-weight: normal; vertical-align: baseline; white-space: pre-wrap;">, which previously were only available in a limited set of locales, are supported globally.  Users viewing your site’s results in Google search can now preview information about products available on your website, regardless of where they’re searching from.
