The page may stay on this queue for a few seconds, but it can take longer than that. Once Google\u2019s 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.\u201d<\/li>\n<\/ul>\n<p>Google clearly states that JavaScript rendering doesn\u2019t necessarily happen on the initial crawl. Once resources allow, a headless browser is used to parse JavaScript.\u00a0<\/p>\n<p>Googlebot likely won\u2019t click on all JavaScript elements, so this probably only includes scripts that don\u2019t require user interactions to fire.<\/p>\n<p>This is important because it tells us Google may make some basic determinations before JavaScript is rendered, via subsequent execution queues.\u00a0<\/p>\n<p>If content is generated behind elements (content tabs, etc.) that Google doesn\u2019t click, it likely won\u2019t be discovered without no-JavaScript fallbacks.<\/p>\n<p>Looking at Google\u2019s \u201c<a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/developers.google.com\/search\/docs\/fundamentals\/how-search-works\" target=\"_blank\" rel=\"noopener\">How Search works<\/a>\u201d documentation:<\/p>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1795\" height=\"1585\" http: alt=\"Image 99\" class=\"wp-image-474614\" srcset=\"https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-99.png.webp 1795w,https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-99-768x678.png.webp 768w,https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-99-1536x1356.png 1536w\" data-lazy-sizes=\"(max-width: 1795px) 100vw, 1795px\" src=\"https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-99.png.webp\"><img loading=\"lazy\" decoding=\"async\" width=\"1795\" height=\"1585\" src=\"https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-99.png.webp\" alt=\"Image 99\" class=\"wp-image-474614\" srcset=\"https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-99.png.webp 1795w,https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-99-768x678.png.webp 768w,https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-99-1536x1356.png 1536w\" sizes=\"auto, (max-width: 1795px) 100vw, 1795px\"><\/figure>\n<\/div>\n<p>The language is much simpler. Google states it will attempt, at some point, to execute any discovered JavaScript. There\u2019s nothing here that directly contradicts what we\u2019ve seen so far in other Google documentation.<\/p>\n<p>On March 31, Google published a post titled \u201c<a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/developers.google.com\/search\/blog\/2026\/03\/crawler-blog-post\" target=\"_blank\" rel=\"noopener\">Inside Googlebot: demystifying crawling, fetching, and the bytes we process<\/a>,\u201d which further clarifies JavaScript crawling.<\/p>\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"2048\" height=\"1336\" http: alt=\"Image 103\" class=\"wp-image-474618\" srcset=\"https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-103.png.webp 2048w,https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-103-768x501.png.webp 768w,https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-103-1536x1002.png 1536w\" data-lazy-sizes=\"(max-width: 2048px) 100vw, 2048px\" src=\"https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-103.png.webp\"><img loading=\"lazy\" decoding=\"async\" width=\"2048\" height=\"1336\" src=\"https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-103.png.webp\" alt=\"Image 103\" class=\"wp-image-474618\" srcset=\"https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-103.png.webp 2048w,https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-103-768x501.png.webp 768w,https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-103-1536x1002.png 1536w\" sizes=\"auto, (max-width: 2048px) 100vw, 2048px\"><\/figure>\n<p>The notes on partial fetching are particularly interesting. Google will only crawl up to 2MB of HTML. If a page exceeds this, Google won\u2019t discard it entirely, but instead examines only the first 2MB of returned code.<\/p>\n<p>Google explicitly states that extreme resource bloat, including large JavaScript modules, can still be a problem for indexing and ranking.\u00a0<\/p>\n<p>If your JavaScript approaches 2MB and appears at the top of the page, it may push HTML content far enough down that Google won\u2019t see it. The 2MB limit also applies to individual resources pulled into a page. If a CSS file, image, or JavaScript module exceeds 2MB, Google will ignore it.<\/p>\n<p>We\u2019re beginning to see that Google\u2019s claim that it renders all pages comes with important caveats.\u00a0<\/p>\n<p>In practice, it seems unlikely that a page with no consideration for server-side rendering (SSR) or no-JavaScript fallbacks would be handled optimally. This highlights why it\u2019s risky to take comments from Googlers at face value without following how the details evolve over time.<\/p>\n<p>The question we opened with is also evolving.

Google suggests either omitting canonical directives from the source HTML so they\u2019re only evaluated after rendering, or ensuring JavaScript doesn\u2019t modify them.<\/p>\n<p>These updates reinforce an important point: even as Google becomes more capable at rendering JavaScript, the initial HTML response and status code still play a critical role in discovery, canonical handling, and error processing.<\/p>\n<p><strong><em>Dig deeper: Google removes accessibility section from JavaScript SEO section<\/em><\/strong><\/p>\n<p><!-- START INLINE FORM --><\/p>\n<p><!-- END INLINE FORM --><\/p>\n<hr class=\"wp-block-separator has-text-color has-cyan-bluish-gray-color has-css-opacity has-cyan-bluish-gray-background-color has-background\">\n<h2 id=\"what-the-data-shows\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_the_data_shows\"><\/span>What the data shows<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>JavaScript rendering is introducing new inconsistencies across the web, according to <a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/httparchive.org\/reports\/search-engine-optimization#canonical\">recent HTTP Archive data<\/a>:<\/p>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"2048\" height=\"1064\" http: alt=\"Image 98\" class=\"wp-image-474612\" srcset=\"https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-98.png.webp 2048w,https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-98-768x399.png.webp 768w,https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-98-1536x798.png 1536w\" data-lazy-sizes=\"(max-width: 2048px) 100vw, 2048px\" src=\"https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-98.png.webp\"><img loading=\"lazy\" decoding=\"async\" width=\"2048\" height=\"1064\" src=\"https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-98.png.webp\" alt=\"Image 98\" class=\"wp-image-474612\" srcset=\"https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-98.png.webp 2048w,https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-98-768x399.png.webp 768w,https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-98-1536x798.png 1536w\" sizes=\"auto, (max-width: 2048px) 100vw, 2048px\"><\/figure>\n<\/div>\n<p>We can see that since November 2024, the percentage of crawled pages with valid canonical links has dropped.<\/p>\n<p>Via the <a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/almanac.httparchive.org\/en\/2025\/seo#raw-versus-rendered-canonical-tags\" target=\"_blank\" rel=\"noopener\">HTTP Archives 2025 Almanac<\/a>:<\/p>\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1539\" height=\"1203\" http: alt=\"Image 95\" class=\"wp-image-474609\" srcset=\"https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-95.png.webp 1539w,https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-95-768x600.png.webp 768w,https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-95-1536x1201.png 1536w\" data-lazy-sizes=\"(max-width: 1539px) 100vw, 1539px\" src=\"https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-95.png.webp\"><img loading=\"lazy\" decoding=\"async\" width=\"1539\" height=\"1203\" src=\"https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-95.png.webp\" alt=\"Image 95\" class=\"wp-image-474609\" srcset=\"https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-95.png.webp 1539w,https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-95-768x600.png.webp 768w,https:\/\/searchengineland.com\/wp-content\/seloads\/2026\/04\/image-95-1536x1201.png 1536w\" sizes=\"auto, (max-width: 1539px) 100vw, 1539px\"><\/figure>\n<p>About 2-3% of rendered pages exhibit a \u201cchanged\u201d canonical URL, something Google\u2019s documentation explicitly states can be confusing for its indexing and ranking systems.

However, 100,000 fetches is a relatively small sample given Googlebot\u2019s scale.\u00a0<\/p>\n<p>The study was also limited to sites built on specific frameworks, so it\u2019s unwise to assume Google always renders pages perfectly. It\u2019s also unclear how deeply those renders were analyzed.<\/p>\n<p>It does suggest that Google attempts to fully render most pages it encounters. Broadly speaking, Google can generate JavaScript-modified renders, but the quality of those renders is still up for debate. As noted earlier, the 2MB page and resource limits still apply.<\/p>\n<p>Because this study dates to mid-2024, any contradictions with Google\u2019s updated 2025\u20132026 documentation should take precedence.<\/p>\n<p>Vercel also published a <a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/vercel.com\/i\/how-ai-is-changing-seo\" target=\"_blank\" rel=\"noopener\">notable finding<\/a>:<\/p>\n<ul class=\"wp-block-list\">\n<li>\u201cMost AI crawlers don\u2019t execute JavaScript.

As these systems become more important, the need for fallbacks may increase again.<\/li>\n<li>Blanket, site-wide no-JavaScript fallbacks aren\u2019t universally required in 2026, but critical content, links, and signals shouldn\u2019t depend entirely on JavaScript. Many modern crawlers still rely on HTML-first delivery.<\/li>\n<\/ul>\n<p>For now, no-JavaScript fallbacks for critical architecture, links, and content are still strongly recommended, if not required going forward.<\/p>\n<\/div>\n<blockquote><p><strong><span style=\"color: #ff6600;\">If you liked the article, do not forget to share it with your friends.
