Does site speed affect AI visibility?
Indirectly. Speed itself is not scored, but a page that times out during a fetch simply is not read.
No assistant is ranking you by load time the way a Core Web Vitals report does. There is no speed multiplier on being recommended.
What matters is completing the fetch. Crawlers apply timeouts; a slow or intermittently failing response means the page is skipped, and a skipped page contributes nothing.
Server response time matters more than front-end rendering performance here, because many agents never execute JavaScript at all.
So the bar is reliability rather than speed: return a complete server-rendered document, promptly, every time.
