LCP / INP / CLS
In one line
LCP, INP and CLS are the three metrics that make up Core Web Vitals — measuring loading speed, interactivity (INP replaced FID in March 2024), and visual stability respectively.
Going deeper
LCP (Largest Contentful Paint) measures how long the largest visible element takes to render. Under 2.5 seconds counts as 'Good', and the LCP element is usually a hero image or a large heading.
FID (First Input Delay) used to measure how long the first interaction took to respond, but Google replaced it with INP (Interaction to Next Paint) in March 2024. INP captures the worst interactions across the whole session, which is a far more realistic signal.
CLS (Cumulative Layout Shift) sums up unexpected layout jumps during load. The usual culprits are ad slots and dynamic embeds without reserved dimensions. Aim for under 0.1 to land in 'Good'.
