Google uses several different metrics to measure the experience of your web pages.
This data is then used by Google to determine how user friendly your website is; the better your pages perform, the better your pages will rank.
These metrics include measures that gauge the loading performance, responsiveness and visual stability from a user’s perspective.
Google’s “Core Web Vitals” are the 3 metrics that you really need to address first, they are; LCP (Largest Contentful Paint(, FID (First Input Delay) and CLS (Cumulative Layout Shift).
There are also other important metrics besides these three core performance metrics, but you can get to the others later!
You can track these metrics and other page performance KPIs in the Page Experience tool in Authoritas.
