Site speed, layout stability, and interactivity are measured explicitly and factored into how pages are ranked and surfaced.
Loading Speed
Oversized images, unoptimized fonts, and render-blocking scripts are still the most common causes of slow loading times.
Layout Stability
Ads, images, and embeds that load without reserved space cause visible content jumps that frustrate visitors and hurt your score.
Interactivity
Heavy third-party scripts that load before your main content delay how quickly a page responds to clicks and taps.
