What is JavaScript SEO?

JavaScript SEO is the set of practices that ensure content rendered with JavaScript can still be crawled, rendered, and indexed by search engines.

Also known as: JS SEO

Why it matters

Many modern sites build content with JavaScript, and if search engines cannot render it, that content is invisible in search. JavaScript SEO closes that gap.

Who needs it

Sites built on React, Vue, Angular, or other JS frameworks, and single-page apps where content loads client-side.

When it's used

During development of a JS-heavy site, and whenever rendered content fails to appear in the index.
