Largest Contentful Paint is a Core Web Vitals metric that measures when the largest visible content element finishes loading.
Example of Largest Contentful Paint
A large hero image may become the largest content element in the initial viewport. Measuring LCP can reveal that it appears late even when the page starts responding quickly; optimize the actual candidate rather than assuming every image affects the metric equally.
Why Largest Contentful Paint matters
It matters because technical issues can prevent great content from being discovered, rendered, indexed, or trusted. Strong technical foundations protect rankings during redesigns, migrations, content expansion, and platform changes.
