Understanding page experience in Google Search results

Page experience is a set of signals that measure how users perceive the experience of interacting with a web page beyond its pure information value. It includes Core Web Vitals, which is a set of metrics that measure real-world user experience for loading performance, interactivity, and visual stability of the page. It also includes existing Search signals: mobile-friendliness, safe-browsing, HTTPS, and intrusive interstitial guidelines.

Understand how page experience will affect ranking

Once the changes mentioned in our roadmap are rolled out, page experience will join the hundreds of signals that Google considers when generating Search results.

While page experience is important, Google still seeks to rank pages with the best information overall, even if the page experience is subpar. Great page experience doesn't override having great page content. However, in cases where there are many pages that may be similar in relevance, page experience can be much more important for visibility in Search.

When will this go into effect? This guide explains ranking changes that are planned to go live in May 2021. We encourage you to get started on evaluating your sites using the tools and documentation detailed on this page.

Page experience signals

The following signals are important for delivering a good page experience in Google Search:

Page experience signals
Core Web Vitals	The page provides a good user experience, focusing on the aspects of loading, interactivity, and visual stability: Largest Contentful Paint (LCP): Measures loading performance. To provide a good user experience, sites should strive to have LCP occur within the first 2.5 seconds of the page starting to load. First Input Delay (FID): Measures interactivity. To provide a good user experience, sites should strive to have an FID of less than 100 milliseconds. Cumulative Layout Shift (CLS): Measures visual stability. To provide a good user experience, sites should strive to have a CLS score of less than 0.1. Here are some tools that can help you measure and monitor Core Web Vitals.
Mobile-friendly	The page is mobile-friendly. Check if your page is mobile-friendly with the Mobile-Friendly Test.
Safe-browsing	The page doesn't contain malicious (for example, malware) or deceptive (for example, social engineering) content. Check to see if your site has any safe-browsing issues with the Security Issues report.
HTTPS	The page is served over HTTPS. Check if your site's connection is secure. If the page isn't served over HTTPS, learn how to secure your site with HTTPS.
No intrusive interstitials	The content on the page is easily accessible to the user. Learn how interstitials can make content less accessible.

Note: We intend to update the page experience signals on an annual basis.

Optimizing your page experience
