iFrame Loophole Won’t Work For Google Core Web Vitals & Page Experience Update
https://www.seroundtable.comApparently there is a loophole in the Lighthouse and DevTools version PageSpeed Insights which skips iframes when calculating Largest Contentful Paint scores. So if you load the entire site in an iframe you might get a score of 100.
That said, the CrUX does account for iframe content so don’t that to help you with Google’s Core Web Vitals & Page Experience Update coming in May.
