Why it matters
Search engines can run JavaScript, but it’s slower and less reliable than reading plain HTML. Content, links or metadata that depend on scripts can be missed or indexed late. This comes up often on React and Next.js builds and on heavy page builders.
Signs you need this
- Your site is built with React, Next.js, Vue or a heavy page builder
- Pages look empty when you view the page source
- Google’s URL Inspection shows missing text or links in the rendered page
- New pages take a long time to appear in search
What we do
Compare what crawlers see
We compare the raw HTML with the rendered page to find content and links that only exist after scripts run.
Choose the fix
Depending on your setup, that’s server-side rendering, static generation, pre-rendering, or moving key content into plain HTML.
Implement and verify
We make the change in the codebase, or alongside your developers, then test with Google’s URL Inspection tool.
How we check it worked
We re-inspect key pages to confirm the rendered HTML holds the full content, and watch how quickly new pages get indexed.
Common questions
Does Google index JavaScript sites?
Yes, but rendering can be delayed, and script errors can stop content being seen at all.
Do we have to rebuild our site?
Usually not. Pre-rendering or server rendering can often be added to the existing site.

JavaScript rendering problems happen when a site’s content only appears after scripts run, so search engines may see a blank or partial page.
