Static HTML vs JS-rendered
Compare the public HTML fetch (what SEOHub audits by default) with a browser-rendered snapshot via DataForSEO Instant Pages when configured.
See what crawlers get without JavaScript
Compare the static HTML response with a JavaScript-rendered snapshot so you can spot content that only appears after client-side frameworks hydrate. Marketing sites on React, Vue, Framer, and similar stacks often look complete in a browser while bots see thin shells.
If the rendered view adds critical copy, titles, or links the raw HTML lacks, fix SSR, prerendering, or meta generation at the template layer — not with more client widgets. Follow up with a free homepage scan and, when needed, a full-site crawl for template-wide gaps.
No account required. Use this before blaming rankings on “content quality” when the real issue is what Googlebot received on first fetch.
FAQ
Does Google always execute JavaScript?
Google can render JS, but it is slower and imperfect. Critical titles, body copy, and links should still appear in the initial HTML whenever possible.
When should I worry?
When important headings, product details, or nav links are missing from the static HTML but present after render — especially on money pages.
