the JavaScript SEO basics</h1> <aside class="key-point"> Do you suspect that JavaScript issues might be blocking your page or some of your content from showing up in Google Search? Learn how to fix JavaScript-related problems with our <a href="/search/docs/guides/fix-search-javascript">troubleshooting guide</a>. </aside> JavaScript is an important part of the web platform because it provides many features that turn the web into a powerful application platform. Making your JavaScript-powered web applications discoverable via Google Search can help you find new users and re-engage existing users as they search for the content your web app provides. While Google Search runs JavaScript with an <a href="/search/blog/2019/05/the-new-evergreen-googlebot">evergreen version of Chromium</a>, there are <a href="/search/docs/guides/fix-search-javascript">a few things that you can optimize</a>. This guide describes how Google Search processes JavaScript and best practices for improving JavaScript web apps for Google Search. <div class="video-wrapper-full-width"><devsite-video video-id="nwGY-9lwTF4"></devsite-video></div> <h2 id="how-googlebot-processes-javascript" data-text="How Google processes JavaScript" tabindex="-1">How Google processes JavaScript</h2> Google processes JavaScript web apps in three main phases: <ol> <li>Crawling</li> <li>Rendering</li> <li>Indexing</li> </ol> <img src="/static/search/docs/images/googlebot-crawl-render-index.png" alt="Googlebot takes a URL from the crawl queue, crawls it, then passes it into the processing stage. The processing stage extracts links that go back on the crawl queue and queues the page for rendering. The page goes from the render queue to the renderer which passes the rendered HTML back to processing which indexes the content and extracts links to put them into the crawl queue." /> Googlebot queues pages for both crawling and rendering. It is not immediately obvious when a page is waiting for crawling and when it is waiting for rendering. When Googlebot fetches a URL from the crawling queue by making an HTTP request, it first checks if you allow crawling. Googlebot reads the <a href="/search/reference/robots_txt">robots.txt</a> file. If it marks the URL as disallowed, then Googlebot skips making an HTTP request to this URL and skips the URL. Google Search won't render JavaScript from blocked files or on blocked pages. Googlebot then parses the response for other URLs in the <code translate="no" dir="ltr">href</code> attribute of HTML links and adds the URLs to the crawl queue. To prevent link discovery, use the <a href="/search/docs/crawling-indexing/qualify-outbound-links"><code translate="no" dir="ltr">nofollow</code> mechanism</a>. <aside class="note"> It's fine to use JavaScript to inject links into the DOM, as long as such links follow the <a href="/search/docs/crawling-indexing/links-crawlable#crawlable-links">best practices for crawlable links</a>. </aside> Crawling a URL and parsing the HTML response works well for classical websites or server-side rendered pages where the HTML in the HTTP response contains all content. Some JavaScript sites may use the <a href="/web/fundamentals/architecture/app-shell" class="external-link">app shell model</a> where the initial HTML does not contain the actual content and Google needs to execute JavaScript before being able to see the actual page content that JavaScript generates. Googlebot queues all pages for rendering, unless a <a href="/search/docs/crawling-indexing/robots-meta-tag">robots <code translate="no" dir="ltr">meta</code> tag or header</a> tells Google not to index the page. The page may stay on this queue for a few seconds, but it can take longer than that. Once Google's resources allow, a headless Chromium renders the page and executes the JavaScript. Googlebot parses the rendered HTML for links again and queues the URLs it finds for crawling. Google also uses the rendered HTML to index the page. Keep in mind that <a href="/web/updates/2019/02/rendering-on-the-web" class="external-link">server-side or pre-rendering</a> is still a great idea because it makes your website faster for users and crawlers, and not all bots can run JavaScript. <h2 id="titles-and-snippets" data-text="Describe your page with unique titles and snippets" tabindex="-1">Describe your page with unique titles and snippets</h2> Unique, descriptive <a href="/search/docs/appearance/title-link#page-titles"><code translate="no" dir="ltr"><title></code> elements</a> and <a href="/search/docs/appearance/snippet#meta-descriptions">meta descriptions</a> help users quickly identify the best result for their goal. You can use JavaScript to set or change the meta description as well as the <code translate="no" dir="ltr"><title></code> element. <h2 id="write-compatible-code" data-text="Write compatible code" tabindex="-1">Write compatible code</h2> Browsers offer many APIs and JavaScript is a quickly-evolving language. Google has some limitations regarding which APIs and JavaScript features it supports. To make sure your code is compatible with Google, follow our <a href="/search/docs/guides/fix-search-javascript">guidelines for troubleshooting JavaScript problems</a>. We recommend <a href="https://web.dev/articles/codelab-serve-modern-code" class="external-link">using differential serving and polyfills</a> if you feature-detect a missing browser API that you need. Since some browser features cannot be polyfilled, we recommend that you check the polyfill documentation for potential limitations. <h2 id="use-meaningful-http-status-codes" data-text="Use meaningful HTTP status codes" tabindex="-1">Use meaningful HTTP status codes</h2> Googlebot uses <a href="/search/docs/crawling-indexing/http-network-errors">HTTP status codes</a> to find out if something went wrong when crawling the page. To tell Googlebot if a page can't be crawled or indexed, use a meaningful status code, like a <code translate="no" dir="ltr">404</code> for a page that could not be found or a <code translate="no" dir="ltr">401</code> code for pages behind a login. You can use HTTP status codes to tell Googlebot if a page has moved to a new URL, so that the index can be updated accordingly. Here's a <a href="/search/docs/crawling-indexing/http-network-errors#http-status-codes">list of HTTP status codes</a> and how they effect Google Search. <h3 id="avoid-soft-404s" data-text="Avoid soft 404 errors in single-page apps" tabindex="-1">Avoid <code translate="no" dir="ltr">soft 404</code> errors in single-page apps</h3> In client-side rendered single-page apps, routing is often implemented as client-side routing. In this case, using meaningful HTTP status codes can be impossible or impractical. To avoid <a href="/search/docs/crawling-indexing/http-network-errors#soft-404-errors"><code translate="no" dir="ltr">soft 404</code> errors</a> when using client-side rendering and routing, use one of the following strategies: <ul> <li>Use a <a href="/search/docs/crawling-indexing/301-redirects#jslocation">JavaScript redirect</a> to a URL for which the server responds with a <code translate="no" dir="ltr">404</code> HTTP status code (for example <code translate="no" dir="ltr">/not-found</code>).</li> <li>Add a <code translate="no" dir="ltr"><meta name="robots" content="noindex"></code> to error pages using JavaScript.</li> </ul> Here is sample code for the redirect approach: <div></div><devsite-code><pre class="devsite-click-to-copy" data-label="Redirect with JavaScript" translate="no" dir="ltr" is-upgraded syntax="JavaScript">fetch(`/api/products/${productId}`) .then(response => response.json()) .then(product => { if(product.exists) { showProductDetails(product); // shows the product information on the page } else { // this product does not exist, so this is an error page. window.location.href = '/not-found'; // redirect to 404 page on the server. } })</pre></devsite-code> Here is sample code for the <code translate="no" dir="ltr">noindex</code> tag approach: <div></div><devsite-code><pre class="devsite-click-to-copy" data-label="Add noindex to error pages with JavaScript" translate="no" dir="ltr" is-upgraded syntax="JavaScript">fetch(`/api/products/${productId}`) .then(response => response.json()) .then(product => { if(product.exists) { showProductDetails(product); // shows the product information on the page } else { // this product does not exist, so this is an error page. // Note: This example assumes there is no other robots meta tag present in the HTML. const metaRobots = document.createElement('meta'); metaRobots.name = 'robots'; metaRobots.content = 'noindex'; document.head.appendChild(metaRobots); } })</pre></devsite-code> <h2 id="use-history-api" data-text="Use the History API instead of fragments" tabindex="-1">Use the History API instead of fragments</h2> Google can only discover your links if they are <a href="/search/docs/crawling-indexing/links-crawlable"><code translate="no" dir="ltr"><a></code> HTML elements with an <code translate="no" dir="ltr">href</code> attribute</a>. For single-page applications with client-side routing, use the <a href="https://developer.mozilla.org/en-US/docs/Web/API/History" class="external-link">History API</a> to implement routing between different views of your web app. To ensure that Googlebot can parse and extract your URLs, don't use fragments to load different page content. The following example is a bad practice, because Googlebot can't reliably resolve the URLs: <div></div><devsite-code><pre class="devsite-click-to-copy" data-label="Bad example with URL fragments" translate="no" dir="ltr" is-upgraded syntax="JavaScript"><nav> <ul> <li><a href="#/products">Our products</a></li> <li><a href="#/services">Our services</a></li> </ul> </nav> <h1>Welcome to example.com!</h1> <div id="placeholder"> <p>Learn more about <a href="#/products">our products</a> and <a href="#/services">our services</p> </div> <script> window.addEventListener('hashchange', function goToPage() { // this function loads different content based on the current URL fragment const pageToLoad = window.location.hash.slice(1); // URL fragment document.getElementById('placeholder').innerHTML = load(pageToLoad); }); </script></pre></devsite-code> Instead, you can make sure your URLs are accessible to Googlebot by implementing the History API: <div></div><devsite-code><pre class="devsite-click-to-copy" data-label="Using the History API" translate="no" dir="ltr" is-upgraded syntax="JavaScript"><nav> <ul> <li><a href="/products">Our products</a></li> <li><a href="/services">Our services</a></li> </ul> </nav> <h1>Welcome to example.com!</h1> <div id="placeholder"> <p>Learn more about <a href="/products">our products</a> and <a href="/services">our services</p> </div> <script> function goToPage(event) { event.preventDefault(); // stop the browser from navigating to the destination URL. const hrefUrl = event.target.getAttribute('href'); const pageToLoad = hrefUrl.slice(1); // remove the leading slash document.getElementById('placeholder').innerHTML = load(pageToLoad); window.history.pushState({}, window.title, hrefUrl) // Update URL as well as browser history. } // Enable client-side routing for all links on the page document.querySelectorAll('a').forEach(link => link.addEventListener('click', goToPage)); </script></pre></devsite-code> <h2 id="properly-inject-canonical-links" data-text='Properly inject the rel="canonical" link tag' tabindex="-1">Properly inject the <code translate="no" dir="ltr">rel="canonical"</code> link tag</h2> While we don't recommend using JavaScript for this, it is possible to inject a <a href="/search/docs/crawling-indexing/consolidate-duplicate-urls#rel-canonical-link-method"><code translate="no" dir="ltr">rel="canonical"</code> link tag</a> with JavaScript. Google Search will pick up the injected canonical URL when rendering the page. Here is an example to inject a <code translate="no" dir="ltr">rel="canonical"</code> link tag with JavaScript: <div></div><devsite-code><pre class="devsite-click-to-copy" data-label="Add rel=canonical with JavaScript" translate="no" dir="ltr" is-upgraded syntax="JavaScript">fetch('/api/cats/' + id) .then(function (response) { return response.json(); }) .then(function (cat) { // creates a canonical link tag and dynamically builds the URL // e.g. https://example.com/cats/simba const linkTag = document.createElement('link'); linkTag.setAttribute('rel', 'canonical'); linkTag.href = 'https://example.com/cats/' + cat.urlFriendlyName; document.head.appendChild(linkTag); });</pre></devsite-code> <aside class="warning"> When using JavaScript to inject the <code translate="no" dir="ltr">rel="canonical"</code> link tag, make sure that this is the only <code translate="no" dir="ltr">rel="canonical"</code> link tag on the page. Incorrect implementations might create multiple <code translate="no" dir="ltr">rel="canonical"</code> link tag or change an existing <code translate="no" dir="ltr">rel="canonical"</code> link tag. Conflicting or multiple <code translate="no" dir="ltr">rel="canonical"</code> link tags may lead to unexpected results. </aside> <h2 id="use-meta-robots-tags-carefully" data-text="Use robots meta tags carefully" tabindex="-1">Use robots <code translate="no" dir="ltr">meta</code> tags carefully</h2> You can prevent Google from indexing a page or following links through the robots <code translate="no" dir="ltr">meta</code> tag. For example, adding the following <code translate="no" dir="ltr">meta</code> tag to the top of your page blocks Google from indexing the page: <div></div><devsite-code><pre class="devsite-click-to-copy" data-label="robots noindex, nofollow" translate="no" dir="ltr" is-upgraded syntax="JavaScript"> <meta name="robots" content="noindex, nofollow"></pre></devsite-code> You can use JavaScript to add a robots <code translate="no" dir="ltr">meta</code> tag to a page or change its content. The following example code shows how to change the robots <code translate="no" dir="ltr">meta</code> tag with JavaScript to prevent indexing of the current page if an API call doesn't return content. <div></div><devsite-code><pre class="devsite-click-to-copy" data-label="Changing the robots meta tag with JavaScript" translate="no" dir="ltr" is-upgraded syntax="JavaScript">fetch('/api/products/' + productId) .then(function (response) { return response.json(); }) .then(function (apiResponse) { if (apiResponse.isError) { // get the robots <code translate="no" dir="ltr">meta</code> tag var metaRobots = document.querySelector('meta[name="robots"]'); // if there was no robots <code translate="no" dir="ltr">meta</code> tag, add one if (!metaRobots) { metaRobots = document.createElement('meta'); metaRobots.setAttribute('name', 'robots'); document.head.appendChild(metaRobots); } // tell Google to exclude this page from the index metaRobots.setAttribute('content', 'noindex'); // display an error message to the user errorMsg.textContent = 'This product is no longer available'; return; } // display product information // ... });</pre></devsite-code> When Google encounters <code translate="no" dir="ltr">noindex</code> in the robots <code translate="no" dir="ltr">meta</code> tag before running JavaScript, it doesn't render or index the page. <aside class="warning"> If Google encounters the <code translate="no" dir="ltr">noindex</code> tag, it skips rendering and JavaScript execution. Because Google skips your JavaScript in this case, there is no chance to remove the tag from the page. Using JavaScript to change or remove the robots <code translate="no" dir="ltr">meta</code> tag might not work as expected. Google skips rendering and JavaScript execution if the robots <code translate="no" dir="ltr">meta</code> tag initially contains <code translate="no" dir="ltr">noindex</code>. If there is a possibility that you do want the page indexed, don't use a <code translate="no" dir="ltr">noindex</code> tag in the original page code. </aside> <h2 id="caching" data-text="Use long-lived caching" tabindex="-1">Use long-lived caching</h2> Googlebot caches aggressively in order to reduce network requests and resource usage. WRS may ignore caching headers. This may lead WRS to use outdated JavaScript or CSS resources. Content fingerprinting avoids this problem by making a fingerprint of the content part of the filename, like <code translate="no" dir="ltr">main.2bb85551.js</code>. The fingerprint depends on the content of the file, so updates generate a different filename every time. Check out the <a href="https://web.dev/articles/http-cache#versioned-urls" class="external-link">web.dev guide on long-lived caching strategies</a> to learn more. <h2 id="structured-data" data-text="Use structured data" tabindex="-1">Use structured data</h2> When using <a href="/search/docs/appearance/structured-data/intro-structured-data">structured data</a> on your pages, you can use <a href="/search/docs/guides/generate-structured-data-with-javascript#testing">JavaScript to generate the required JSON-LD and inject it into the page</a>. Make sure to <a href="/search/docs/guides/debug">test your implementation</a> to avoid issues. <h2 id="web-components" data-text="Follow best practices for web components" tabindex="-1">Follow best practices for web components</h2> Google supports web components. When Google renders a page, it <a href="/web/fundamentals/web-components/shadowdom#lightdom" class="external-link">flattens the shadow DOM and light DOM</a> content. This means Google can only see content that's visible in the rendered HTML. To make sure that Google can still see your content after it's rendered, use the <a href="https://search.google.com/test/rich-results" class="external-link">Rich Results Test</a> or the <a href="https://support.google.com/webmasters/answer/9012289" class="external-link">URL Inspection Tool</a> and look at the rendered HTML. If the content isn't visible in the rendered HTML, Google won't be able to index it. The following example creates a web component that displays its light DOM content inside its shadow DOM. One way to make sure both light DOM and shadow DOM content is displayed in the rendered HTML is to use a <a href="/web/fundamentals/web-components/shadowdom#slots" class="external-link">Slot</a> element. <div></div><devsite-code><pre class="devsite-click-to-copy" data-label="Creating light DOM inside shadow DOM" translate="no" dir="ltr" is-upgraded syntax="HTML"><script> class MyComponent extends HTMLElement { constructor() { super(); this.attachShadow({ mode: 'open' }); } connectedCallback() { let p = document.createElement('p'); p.innerHTML = 'Hello World, this is shadow DOM content. Here comes the light DOM: <slot></slot>'; this.shadowRoot.appendChild(p); } } window.customElements.define('my-component', MyComponent); </script> <my-component> This is light DOM content. It's projected into the shadow DOM. WRS renders this content as well as the shadow DOM content. </my-component></pre></devsite-code> After rendering, Google can index this content: <div></div><devsite-code><pre class="devsite-click-to-copy" data-label="DOM content after rendering" translate="no" dir="ltr" is-upgraded syntax="HTML"><my-component> Hello World, this is shadow DOM content. Here comes the light DOM: This is light DOM content.

A good strategy is to use lazy-loading to only load images when the user is about to see them. To make sure you're implementing lazy-loading in a search-friendly way, follow <a href="/search/docs/guides/lazy-loading">our lazy-loading guidelines</a>. <h2 id="accessibility" data-text="Design for accessibility" tabindex="-1">Design for accessibility</h2> Create pages for users, not just search engines. When you're designing your site, think about the needs of your users, including those who may not be using a JavaScript-capable browser (for example, people who use screen readers or less advanced mobile devices). One of the easiest ways to test your site's accessibility is to preview it in your browser with JavaScript turned off, or to view it in a text-only browser such as Lynx. Viewing a site as text-only can also help you identify other content which may be hard for Google to see, such as text embedded in images. <devsite-hats-survey class="nocontent" hats-id="egUfosvgZ0gb2CML1jd0VMoBx2ec" listnr-id="103417"></devsite-hats-survey> </div> <devsite-thumb-rating position="footer"> </devsite-thumb-rating> <devsite-feedback position="footer" project-name="Documentation" product-id="103417" bucket="Search Docs" context="DevSite feedback link" version="t-devsite-webserver-20241114-r00-rc02.464922260396498922" data-label="Send Feedback Button" track-type="feedback" track-name="sendFeedbackLink" track-metadata-position="footer" class="nocontent" disable-product-feedback project-icon="https://developers.google.com/static/search/images/google-search-central-logo.svg" project-support-url="https://developers.google.com/search/help" > <button> Send feedback </button> </devsite-feedback> <div class="devsite-floating-action-buttons"> </div> </article> <devsite-content-footer class="nocontent"> Except as otherwise noted, the content of this page is licensed under the <a href="https://creativecommons.org/licenses/by/4.0/">Creative Commons Attribution 4.0 License</a>, and code samples are licensed under the <a href="https://www.apache.org/licenses/LICENSE-2.0">Apache 2.0 License</a>.
