JavaScript & React SEO
Sites built quickly with AI tools often look great and send crawlers an almost empty page. That is fixable.

JavaScript SEO makes sites built with React, Vue or AI site builders readable to search engines and AI crawlers. Google can render JavaScript, but many AI crawlers read only the raw HTML. We move key content into the initial HTML with server rendering or prerendering and fix routing, links and metadata.
Why it matters now
If your content only appears after JavaScript runs, some crawlers see a blank shell. That keeps you out of AI answers even when Google eventually indexes the page.

Frequently asked questions
Does Google index JavaScript sites?
Google renders JavaScript, though rendering can be delayed and some patterns fail. Many AI crawlers do not render at all, which is why content in the initial HTML matters.
Do we have to rebuild the site?
Not always. Prerendering can often be added to an existing single-page app. We recommend a rebuild only when the architecture makes it the cheaper path.
