JavaScript SEO
JavaScript SEO is making sure search engines and AI crawlers can see content and links that a site builds with JavaScript, as on many React, Vue or Angular sites.
Why it matters
Google can render JavaScript, but it takes extra time and resources, and many AI crawlers don't render it at all. Content that only appears after scripts run may be indexed late or never quoted.
How to get it right
- Render key content on the server (SSR) or at build time (static generation).
- Use real links (<a href>) for navigation, not click handlers.
- Put titles, meta tags and structured data in the initial HTML.
- Check pages with Search Console's URL Inspection and by viewing the raw HTML.
Frequently asked questions
Yes. Frameworks like Next.js render pages on the server or at build time, so crawlers get full HTML.
Many don't, so server-rendered content is the safest way to be read and cited.
