<p>The <b>Page Previews </b> feature solves the core problem of users needing to open multiple tabs to gain an understanding of a word or concept within the context of the subject they are reading. With Page Previews, whenever a reader hovers over a link to another article, a short summary of the subject and an image (if available) is displayed. The user can then decide whether they wish to visit that subject more thoroughly before continuing with the current article. A complete description of <a href="/wiki/Special:MyLanguage/Page_Previews/Functionality" title="Special:MyLanguage/Page Previews/Functionality">Page Previews functionality</a> is available. An overview over all related technical documentation is provided in <a class="external text" href="https://blog.wikimedia.org/2018/05/09/page-previews-documentation/">this blog post</a> from May 2018. </p><p>The <b>Reference Previews</b> feature is a related project. It shows a preview of a footnote whenever a reader hovers over its footnote marker. A description of this feature can be found on <a href="https://meta.wikimedia.org/wiki/WMDE_Technical_Wishes/ReferencePreviews" class="extiw" title="m:WMDE Technical Wishes/ReferencePreviews">its project page</a>. </p> <meta property="mw:PageProp/toc"/> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="Introduction" data-mw-thread-id="h-Introduction"><span data-mw-comment-start="" id="h-Introduction"></span>Introduction<span data-mw-comment-end="h-Introduction"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Page_Previews&action=edit&section=1" title="Edit section: Introduction"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span><!--__DTELLIPSISBUTTON__{"threadItem":{"headingLevel":2,"name":"h-","type":"heading","level":0,"id":"h-Introduction","replies":[]}}--></div> <p>Page Previews are designed to reduce the cost of exploration of a link, as well as to promote learning by allowing readers to gain context on the article they are reading or to define an unfamiliar term, object, event, or idea without navigating away from their original topic. For casual readers, Page Previews will make it easier for users to get an overview of an article before deciding whether or not to browse to it. Users interested in reading an entire article in its totality will not be distracted or discouraged by viewing unfamiliar concepts—they can simply preview the concept without navigating to a new page. Consequently, the smoothness of the user experience for these users will be increased. </p><p>There have been many requests over the years for a similar feature; there are browser extensions (see <a href="/wiki/Topic:Seq3z026jcarkaji" title="Topic:Seq3z026jcarkaji">list</a>) and one heavily used gadget (the more editor-focused <a href="https://en.wikipedia.org/wiki/Wikipedia:Tools/Navigation_popups" class="extiw" title="en:Wikipedia:Tools/Navigation popups">Navigation popups</a>) that also exist to solve this problem. Page Previews were first built as a beta feature in 2014 (called Hovercards) and have been among our most popular beta features in terms of adoption, user feedback and impact on usage. On the <a href="/wiki/Talk:Beta_Features/Hovercards" class="mw-redirect" title="Talk:Beta Features/Hovercards">primary talk page for Hovercards</a>, over the course of 2 years, numerous issues across all projects were identified and resolved. The mobile equivalent of Page Previews, implemented on the Android app <a href="https://diff.wikimedia.org/2015/09/10/Wikipedia-app-new-navigation-features/" class="extiw" title="wmfblog:2015/09/10/Wikipedia-app-new-navigation-features/">in September 2015</a>, led to a 20% increase in links clicked per page. </p><p>The Page Previews <a href="#Settings">settings panel</a> enables logged-out users to enable and disable the feature based on their preferences. Logged-in users may enable or disable Page Previews from the Appearance section of Special:Preferences. If Navigation popups and Page Previews are enabled at the same time (typically, for logged-in users who have opted in via the beta feature), Navigation popups takes precedence. To enable Page Previews, Navigation pop-ups must be disabled. </p> <figure class="mw-halign-none" typeof="mw:File/Thumb"><a href="/wiki/File:Hovercards_-_Alps_Mont_Blanc.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/6/6e/Hovercards_-_Alps_Mont_Blanc.jpg/623px-Hovercards_-_Alps_Mont_Blanc.jpg" decoding="async" width="623" height="324" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/6/6e/Hovercards_-_Alps_Mont_Blanc.jpg/935px-Hovercards_-_Alps_Mont_Blanc.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/6/6e/Hovercards_-_Alps_Mont_Blanc.jpg 2x" data-file-width="1169" data-file-height="608"/></a><figcaption>Example of a Page Preview</figcaption></figure> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="Design" data-mw-thread-id="h-Design"><span data-mw-comment-start="" id="h-Design"></span>Design<span data-mw-comment-end="h-Design"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Page_Previews&action=edit&section=2" title="Edit section: Design"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span><!--__DTELLIPSISBUTTON__{"threadItem":{"headingLevel":2,"name":"h-","type":"heading","level":0,"id":"h-Design","replies":["h-Key_differences_from_Navigation_Popups-Design","h-HTML_Previews-Design"]}}--></div> <p>For the current iteration of Page Previews, each preview contains the following: </p> <ul><li>A portion of the first paragraph from the article</li> <li>An image (if available) from the article.

It's inspired by one of the most popular gadgets, <a href="https://en.wikipedia.org/wiki/Wikipedia_talk:Tools/Navigation_popups" class="extiw" title="w:Wikipedia talk:Tools/Navigation popups">Navigation popups</a>.</dd></dl> <dl><dt>How do we measure Page Previews performance?</dt> <dd>The theory of impact for Page Previews is that they lower the cost of exploring a link. This should mean that users are less inhibited and more focused when exploring links. We should see that the overall links clicked + (non-accidental) hovers exceed the number of links clicked without Page Previews. This is what success looks like. There are also some indications of failure that we will look for: <ul><li>hovers can be accidental - we need to measure normal dwell time in a controlled condition to ensure that the likely rate of accidental hovers is not too high. To give an example, if a user must dwell on a link for 250 msecs before a hover shows, then we would want to make sure that there are not a large number of users who tend to dwell on a link for more than 250 msecs without clicking it.</li> <li>Page Previews could lead to fewer page views, because the user gets the information that they need from the preview- this is not a problem, but we want to make sure that the decrease (if any) does not result in significantly less editing or fundraising.</li> <li>the % of hovers that result in a user continuing to the page is high - this would suggest that most people wanted to go to the page anyway. If this is the case, then the hover is likely just adding an unnecessary step. We expect some significant % of click throughs for hovers. It is ~60% on Android for a similar feature, but we expect it to be lower on desktop.</li> <li>the percentage of users who disable Page Previews is low (given that users are aware on how to disable the feature) - this suggests that users enjoy the feature.</li></ul></dd></dl> <dl><dt>Is this enabled by default for logged-in users?</dt> <dd>No. If you had the feature enabled as a Beta feature you will still have the feature enabled. See Preferences>Appearance>Reading preferences to change the setting.</dd> <dt>What if I have Navpops enabled by default?</dt> <dd>If you have Navpops enabled, Page Previews are automatically disabled. You will have to disable Navpops in order to experience Page Previews. This is an intentional decision to ensure that Navpop users' do not have their preferences interrupted. Note: for certain browsers, you might have to clear your browser cache first for the change to take place.</dd> <dt>How many options do I have in Page Previews preferences?</dt> <dd>Right now, Page Previews will either be turned on or off by a user. The option to turn them off lives in each hover event. So at each hover event, a user can decide that they are no longer interested. For logged-in users, Page Previews may be re-enabled from user settings under the section titled "Appearance". For logged-out users, Page Previews may be re-enabled by selecting the "Enable Previews" link at the bottom of the page.</dd></dl> <p>At the project level, administrators can determine how long a user should dwell on a link before a hover is triggered. If a project wants to be conservative, the lag can be longer. WMF will have a recommendation as to optimum dwell time that provides the best user experience while minimizing accidental hovers. </p> <dl><dt>Why can't users just turn on Page Previews if they want them?</dt> <dd>Unfortunately, there is no good way to tell users about a new feature without showing it to them first.</dd></dl> <p>Central notice banners have been suggested, but running them for 2 weeks would not solve the needs of future users and we do not want to run them continuously. Notifying a user of a new feature is best done using a...hover-over. </p> <dl><dt>What impact to Page Previews have on page views?</dt> <dd>According to A/B tests we did not see a large decrease in session depth across all Wikipedias. Average session depth (average number of pages viewed per session) <a href="/wiki/Page_Previews/2017-18_A/B_Tests#Pageviews_and_Page_Interactions,_effects_on_fundraising" title="Page Previews/2017-18 A/B Tests">remained relatively equal</a> between the Previews on and off groups.</dd> <dt>What about accessibility?</dt> <dd>Page Previews only activate when the focus/hover state occurs over a link. They are usable for people who use keyboard navigation. For screen readers, Page Previews have proper <a href="https://en.wikipedia.org/wiki/WAI-ARIA" class="extiw" title="w:WAI-ARIA">WAI-ARIA</a> semantics declaring them as tooltips. In short, screen reader software ignore Page Previews.</dd> <dt>If I have Page Previews feedback or if I have a suggestion for making them better, where should I go?</dt> <dd>Please go to <a href="/wiki/Talk:Page_Previews" title="Talk:Page Previews">the Page Previews discussion page</a>.</dd> <dt>The Page Previews continues to show an old version of a page.
