LCP gauges how quickly the main content renders, INP measures responsiveness to user input across the whole visit (having replaced First Input Delay in 2024), and CLS quantifies unexpected layout movement. Together they translate perceived speed and stability into thresholds sites can target, measured on real-world field data from Chrome users.
While these metrics are a modest ranking factor, Acromatico treats them as table stakes for both users and crawlers. A fast, stable page is easier for bots to render and extract, and a smooth experience reduces bounce, indirectly supporting the engagement and dwell signals that reinforce visibility in search and AI surfaces.
