Page experience update features a lot of Page experience signals including the three Core Web Vital metrics i.e., LCP, FID, and CLS. Although these are not new metrics but are prioritized in this update to measure user experience more accurately.

We can say that Core web Vitals are indicators that Google is using to evaluate the performance of User Experience (UX) of a webpage.

These metrics are:

  • LCP (Largest Contentful Paint): LCP is an important metric that measures the loading speed of the main content of a page. A fast LCP reassures a user that the page is useful.
  • FID (First input Delay): First Input Delay measures how quickly a webpage responds to a user’s first action on the page. It measures the responsiveness or interactivity of a webpage.
  • CLS (Cumulative Layout Shift): CLS is another important user-centric metric that measures the visual stability of a webpage. This means it measures how stable is the layout of a page.

Page Title Update has not become so popular. Because, this update generates title Tags from Meta tags, H1, H2 tags, and even anchor text of other linked sites. It sometimes generates completely random titles, and it is negatively impacting most web pages.
