Largest Contentful Paint (LCP) is Google's user experience metric. It will be a ranking factor in 2021. This guide explains what LCP is and how to achieve the highest score. Definition of maximum content full paint What is the most satisfying paint? LCP is a measure of how long it takes for the main content of a page to be downloaded and operational. What is measured is the largest image or context block in the user viewport. Anything that extends beyond the screen is not counted. Common elements that are measured are block-level text elements such as images, video poster images, background images, and paragraph tags. Why is LCP measured?

What happens in this case is that the PerformanceEntry of the largest text block level element is logged. However, when the featured image at the top of the screen loads, if that element occupies much of the user screen (viewport), another PerformanceEntry object is reported for that image. advertisement Continue reading below Images of LCP scores can be awkward Web publishers typically upload an image to its original size, then use HTML or CSS to resize the image and display it in
