1. On your computer, open Chrome.
2. At the top right, select More Settings.
3. On the left, select Performance.

   • Add sites manually

Tip: The web address format for the manual site exclusion policy is: [scheme://][.]host[:port][/path][@query].

Here are some examples of how to add sites manually if you want to create an exclusion for:

• Entire domains and subdomains: Exclude the URL scheme. For example, google.com matches and prevents deactivation of subdomains like drive.google.com and calendar.google.com.
• Specific domains, but not any subdomains: Include a dot (.) before the URL host. For example, .google.com won’t match and prevent deactivation of subdomains like google.com, drive.google.com and calendar.google.com.
• Specific sub-directory: Include the URL path. For example, google.com/finance matches and prevents deactivation of all Google Finance pages, but won’t prevent deactivation of the google.com main pages.
• URL host and query components: Asterisks (*) can be used as wildcards. For example, https://* matches and prevents deactivation of all https sites and youtube.com/watch?v=* matches and prevents deactivation of YouTube videos.
  • Wildcards for prefix, suffix or substring matches of the URL host component aren’t supported. For example, *oogle.com or google.com/* won’t match and prevent deactivation.
