reset chrome media engagement score

A quick throwaway solution to have a new window with empty MEI data is to open a "Guest window" by clicking the user avatar and choosing "Open Guest window" button.

Chrome open guest window

The easiest way I found to test using a clean score is to create a new profile in Chrome:

1- At the top right of Chrome, click the button with your name or People People.

2- Click Manage people.

3- Click Add person.

4- Click Save. A new window will open and ask you to sign in.

You can also clean MEI by clearing browsing history:

  • Click Ctrl+Shift+Del or navigate to chrome://settings/clearBrowserData
  • Go to Advanced > All time
  • tick Browsing history
  • Click Clear data
  • Navigate to chrome://media-engagement to verify

Chrome clear MEI data

BTW. Note that notably going into incognito mode doesn't reset MEI; the MEI data are copied from regular session when opening first incognito tab (and then lives on its own until incognito session is closed).
