What does LCP stand for?

Largest Contentful Paint

Largest contentful paint (LCP) is a tool that helps to measure how quickly a website appears to load from a user’s perspective. It was introduced by Google in 2020 as a key part of their ‘core web vitals’, which are designed to objectively assess the user experience (UX) of a website.

What sets LCP apart from other similar measures is that it doesn’t gauge how long it takes for all the parts of a webpage to load. Instead, it times how long it takes for the biggest visible part to show up. This gives a more accurate idea of how fast a website feels to a user.

Google’s research shows that waiting for a page to load is the most common annoyance for web users. This becomes even more of a problem if a user needs to navigate through several pages to get where they want to go.

There are several tools that Google offers to measure and improve LCP. They advise web developers to aim for an LCP of 2.5 seconds or less. This can often mean reducing the size of image files and cutting down the time it takes to load and display text.
