JavaScript Rendering and Why AI Crawlers Skip Your Site
Many AI crawlers don't run JavaScript. If your content only appears after JS, you may be invisible. Here's how to fix it.
The JS visibility problem
Unlike Googlebot, many AI crawlers fetch raw HTML and don't execute JavaScript. If your text, links or schema only appear after client-side rendering, those crawlers see an empty shell.
Serve content in the HTML
Use server-side rendering or static generation so your key content, headings and JSON-LD are present in the initial HTML response, not injected later by JS.
Verify what crawlers see
Check your page's raw HTML (view source or curl) — if the main content isn't there, neither AI crawlers nor your audit will see it.

Use server-side rendering or static generation so key content and schema are in the initial HTML response.
How do I check what crawlers see?⌄
View the page source or curl the URL — if the main content and JSON-LD aren't in the raw HTML, crawlers likely can't read them.
