Does infinite scrolling really harm your SEO?

Why is this clarification happening now?

Infinite scrolling has become commonplace in recent years, especially on e-commerce sites, blogs, and social networks. The idea is simple: instead of paginating content with "next page" buttons, the next elements are automatically loaded when the user scrolls down. From a UX perspective, this is smooth. From an SEO perspective, it can be a trap if not implemented correctly.

John Mueller is revisiting old guidelines because the issue persists. Many sites adopt infinite scrolling without providing direct URLs for each content segment. The result: Googlebot cannot crawl deep pages, which remain invisible in the index. The reminder is clear: the user experience must not sacrifice accessibility for robots.

What does direct access via pagination links mean?

Specifically, this means providing traditional pagination URLs (example.com/page/2, example.com/page/3, etc.) that allow direct loading of a content segment without having to simulate infinite scrolling. These URLs must be accessible through standard HTML links in the source code, not just through client-side JavaScript.

The goal is not to abandon infinite scrolling on the front end. Each "page" dynamically loaded must also correspond to a stable, crawlable URL, with an <a href> link present in the DOM. This way, Googlebot can discover and index all content segments, even those appearing after several scrolls.

Can search engines really crawl modern JavaScript?

Google can execute JavaScript and crawl dynamically loaded content, that's a fact. However, this capability has technical and budgetary limits: JS rendering consumes time and resources. If your infinite scrolling relies on complex scroll events or asynchronous APIs without HTML fallbacks, Googlebot may miss some content segments.

Google's position is consistent: JS rendering is possible, but should not be a crutch to compensate for a failing SEO architecture. Direct access via pagination URLs remains the most reliable method to ensure complete indexing, especially on sites with thousands of pages or limited crawl budgets.

• Stable URLs for each segment: each "page" loaded must correspond to a crawlable URL.
• Standard HTML links: pagination URLs must be accessible through <a href> tags in the source code.
• Do not solely rely on JS: JavaScript rendering has crawl budget and reliability limits.
• User experience preserved: it is possible to combine infinite scrolling on the front end with traditional pagination on the back end.
• Field validation: check in Google Search Console that all deep pages are indexed properly.

Is this guideline still realistic in 2025?

Let's be honest: Google has made significant progress in JavaScript rendering since 2014. The search engine can execute modern JS, crawl Single Page Applications (SPAs), and index content loaded via AJAX. So why this reminder about a directive that is over a decade old?

The answer comes down to two words: crawl budget. JS rendering is costly for Google in terms of time and resources. On a 50-page site, no problem. On a 50,000-item e-commerce catalog, it's a different story. If each deep page requires simulated scrolling and complete rendering, Googlebot may simply stop attempting to crawl all content. Direct URLs remain the most economical and reliable way to ensure complete indexing. [To be verified]: Google does not publish any numerical thresholds on the exact cost of JS rendering compared to classic HTML crawl, but field observations show significant indexing differences.

What are the common implementation errors?

The first error: no HTML fallback. Infinite scrolling relies entirely on client-side JavaScript, with no accessible pagination link in the source code. Googlebot theoretically can execute JS, but won't always do so, especially if the site has a low crawl budget or performance issues.

The second error: pagination URLs exist, but they are not linked together. For example, the homepage dynamically loads products 1 to 20, then 21 to 40, but there are no HTML links pointing to /page/2 or /page/3. The result: Googlebot never discovers these URLs, even if they are technically accessible. Internal linking must explicitly include these pagination links.

The third error: using rel="next" and rel="prev" without providing the URLs themselves. These tags were officially deprecated by Google in 2019. They no longer serve any purpose for indexing. What matters is that pagination links are present in the DOM as standard <a href> tags.

In what cases does this rule not apply?

If your content is strictly personal (a private social feed, a user dashboard), indexing is of no interest. Infinite scrolling without pagination does not pose any SEO problems, since there is nothing to index.

Another case: ephemeral or low-value content. If you do not want Google to index deep pages (for example, outdated archives of little relevance), infinite scrolling without pagination URLs may even be an advantage. However, this strategy must be intentional, not the result of technical neglect. If the content holds value for SEO, it must be crawlable via stable URLs.

How can I check if my site is compliant?

First step: inspect the source code of your pages with infinite scrolling. Display the raw HTML (Ctrl+U or right-click > View page source) and look for <a href> tags pointing to pagination URLs (example.com/page/2, example.com/page/3, etc.). If no such link is present in the initial DOM, Googlebot will not discover these pages, even if it executes your JavaScript.

Second step: use the URL inspection tool in Google Search Console to test the rendering of your pages. Look at the "rendered" version and compare it to the raw HTML. If pagination links only appear in the rendered version (after JS execution), it is a warning sign: you are completely reliant on JavaScript rendering, which weakens indexing.

What specific actions should I take to correct the issue?

The most solid approach is to implement a hybrid pagination: keep the infinite scrolling user experience on the front end while providing traditional pagination URLs in the source code. Technically, this means generating standard HTML links to /page/2, /page/3, etc., even if these links are visually hidden or replaced by JavaScript for real users.

Another solution: use a "load more" button with progressive enhancement. By default, you display a "Load More" button that points to the next pagination URL (standard HTML link). Then, you enhance the experience with JavaScript that intercepts the click and loads content via AJAX, simulating infinite scrolling. If the JS fails or if the bot does not execute it, the HTML link still works.

What mistakes should be absolutely avoided?

Do not rely on rel="next" and rel="prev": these tags have been obsolete since 2019 and Google no longer uses them. Do not depend solely on the XML sitemap to submit your pagination URLs. The sitemap helps with discovery but does not replace a solid internal linking strategy with HTML links in the content.

Avoid blocking the crawl of your pagination URLs via robots.txt or a noindex tag. If you want Google to index the content of deep pages, these URLs must be crawlable and indexable. Finally, do not neglect loading speed: poorly optimized infinite scrolling can degrade Core Web Vitals (especially CLS), which impacts ranking.

• Check for <a href> links to pagination URLs in the raw source code (not just after JS rendering).
• Test the indexing of deep pages in Google Search Console and compare the raw/rendered versions.
• Implement hybrid pagination: infinite scrolling for UX, stable URLs for SEO.
• Avoid complete reliance on JavaScript rendering for URL discovery.
• Do not use rel="next"/"prev": these tags are deprecated and unnecessary.
• Monitor Core Web Vitals (CLS, LCP) to ensure infinite scrolling does not impact performance.
