Definition
Page speed is how quickly a page loads and becomes usable. It covers the time to first content, the time to full interactivity, and the stability of the layout as it loads, the qualities Google now formalizes as Core Web Vitals.Why It Matters for AI Search
Speed is both a ranking factor and a crawling factor. Slow pages are crawled less often and less deeply, so fewer of their passages reach the index a model draws from. Speed also shapes whether a fetcher waits for content or gives up before it renders. For AI search the stakes match traditional search: a page that loads slowly is read less, and a page read less is cited less. Core Web Vitals is the specific standard that turns page speed into measurable targets.Related Terms
