Largest Contentful Paint (LCP)
Measures the perceived load speed by marking when the first large chunk of content is displayed.
The scores we use come from a Google Lighthouse report and represent the 28 day average score for the homepage as measured by real users using Chrome. Websites should aim for an LCP of less than 2.5 seconds. Anything over 4 seconds is considered to be poor.
