Do AI assistants read JavaScript-heavy pages?

Many AI crawlers read the HTML your server sends and do not run the JavaScript a browser would, so content that only appears after client-side scripts execute — text injected by a framework, items loaded on scroll, details revealed by a tab or an accordion — can be invisible to the assistant even though a human sees it perfectly. This is the quiet reason a beautiful, modern site can still read as a near-blank to an AI: the words that decide a recommendation never arrive in the fetched markup. The fix is to make sure your substance — what you do, where, your hours, your core facts and FAQs — is present in server-rendered HTML that shows up even with scripts disabled, rather than assembled in the browser after load. Progressive enhancement is fine; hiding your load-bearing content behind JavaScript is not. A simple test is to view the page with JavaScript turned off: whatever disappears is roughly what the crawler may miss. If the fetched page is empty, nothing else about your AI visibility matters.
