FAQ
How is Lighthouse Different from PageSpeed ​​Insights?
Lighthouse is different from PageSpeed ​​Insights in that Lighthouse only uses lab data to measure the performance of your pages. PageSpeed ​​Insights, on the other hand, uses both lab data and field data.

Lab data reflects the experience of hypothetical users brazil phone data on your site. In contrast, field data reflects the experience of real users on your website.

The scores you see in Lighthouse may vary each time you take the test.

Network conditions, browser extensions that modify network requests, and ads displayed on a specific page affect your score every time you take the test.

Do Lighthouse Reports Include Core Web Vitals Metrics?
Yes. Lighthouse Performance Audit analyzes your website based on the following Core Web Vitals metrics :

Largest Contentful Paint (LCP)
