What makes up Page Experience?
Largest Contentful Paint (LCP)
First Input Delay (FID)
Cumulative Layout Shift (CLS)
It’s often easy to forget the complexities that Google are trying translate into algorithms that spit our search results. User experience for us is different to UX (or Page Experience) for search engines.
Unsurprisingly, robots don’t feel things in the same way that we do. They need to have clear data sets based on pre-determined factors. That’s what Google is doing here. They’re looking for key indicators of a positive user experience. It’s not perfect and far away from how humans experience webpages, but it’s better than nothing.
How important is Page Experience?
It doesn't supersede other major factors
That’s clear to anyone who has read the literature. Unfortunately, there are some in the industry who tend to jump on new updates. The important point is that great page experience will not make up for mediocre content. In does however work the other way around. Great content with mediocre page experience will outrank mediocre content with great page experience.
