Listen: Site Engagement Score

Deep inside your Chrome browser, a quiet metric is tracking how you interact with every website you visit. It is called the Site Engagement Score, and it rates your relationship with a domain on a scale from zero to one hundred.

This score is entirely private. It is computed and stored locally on your device, and is never sent to a server. You earn points for a site through simple daily habits, like navigating to a page, clicking, typing, or even just letting media play in the background. The browser caps your daily points at fifteen, and if you stop visiting a site, your score slowly decays over time.

So why does this matter? While it is not a traditional search engine ranking factor, the Site Engagement Score is a powerful signal of user trust and loyalty. A high score tells Chrome that you value a domain. In response, the browser is more likely to grant that site notification permissions, recommend it in content feeds, or promote it as a web app.

As search evolves, this local data is becoming even more important. Chrome’s on-device artificial intelligence models can use these engagement scores to understand which sites you trust most, helping the AI personalize its responses based on your actual browsing habits.

If you want to see how Chrome views your own habits, you can inspect your live scores at any time. Just type chrome, followed by a colon, two forward slashes, and site-engagement into your address bar to see exactly which domains you visit the most.
