- Updated Largest Contentful Paint (LCP) algorithm to address an issue with Chrome not always reporting the metric accurately
In this Synthetic Agent release we’ll be addressing an issue recently discovered in Chrome where Largest Contentful Paint (LCP) can sometimes be reported as less than First Contentful Paint (FCP). This issue has been reported to Chrome, and you can learn more about it here - https://bugs.chromium.org/p/chromium/issues/detail?id=1279548.
We (Blue Triangle) will be updating our algorithm to set LCP equal to FCP in the event Chrome reports LCP as less than FCP. As a result, you may notice a change to your LCP numbers in Blue Triangle moving forward, depending on the prevalence of the issue on your site(s).
