What Role Does Core Web Vitals Play in Google Lighthouse?

Google recently announced core web vitals, and we expect these to be among the topmost key ranking factors in the future.

Your Lighthouse report, as we mentioned earlier, incorporates invaluable data. This data includes core web vitals- which are among the first insights you’ll find on your Lighthouse report. Three essential metrics are present in core web vitals:

I. Largest Contentful Paint (LCP)

Of all the three metrics in core web vitals, you may find LCP the easiest to understand. It measures the speed of accessing your page’s largest drawn item. That is why this metric is called “Largest Contentful Paint”.

Therefore, you can use LCP to measure your site’s loading speed. If our website lags when loading the most important and biggest content, users are likely to get frustrated and leave the page.

II. First Input Delay (FID)

FID is essential in determining interactivity. It measures user experience errors that tend to annoy any internet user. If you have tried to click the “Download” or “Submit” button several times because the first time failed to work, you know how frustrating such an experience can be.

FID measures the time gap between a user initiating a specific action and the site’s execution of that action.

III. Cumulative Layout Sheet (CLS)

CLS tries to improve your site’s visual stability. You may have noticed that sometimes content shifts around as a site loads. That may be very irritating for a user that wants to click something, but the content keeps moving.
