How to Block Websites in Chrome

Answer Summary

Chrome on a computer can't block a website on its own; there's no built-in setting for it. Instead you add a free extension like BlockSite, which takes under a minute, or sign in with a supervised Family Link profile. Both work; the honest weak spot is that either can be undone.

Key Takeaways

Chrome has no built-in site blocker: add a free extension (BlockSite, StayFocusd, LeechBlock NG) or use a Family Link profile.
Turn on the extension's password protection and uninstall prevention so it can't be casually switched off.
Extensions don't run in Incognito unless you allow it.

Chrome doesn't include a way to block a website; a little surprising, but true. The fix is a free extension you add from the Chrome Web Store, and it takes about a minute. Here's how, plus the settings that stop you from quietly turning it back on.

Step by step

Add a blocking extension (e.g., BlockSite, StayFocusd, LeechBlock NG): Chrome Web Store → search a blocker → Add to Chrome → confirm → pin it. Open the extension → Block Sites tab → + Add to Block List → enter the URL → Done. (Or, on a site, open the extension → Block this site.) Optional: enable password protection and uninstall prevention. To allow in Incognito: puzzle icon → Manage extensions → the blocker → Details → Allow in Incognito.
Or use a supervised profile: a Family Link child account signed into Chrome enforces the family filter (Family Link → child → Controls → Google Chrome and web).

Good to know

Worth knowing: an extension can be disabled or removed by whoever's using the computer (the password and uninstall-prevention settings are what stop that). Extensions also stay off in Incognito unless you allow them, and Family Link's blocking is easy to dodge on a desktop by signing out or switching browsers.

This is one piece of the full guide to blocking websites and apps across your devices.
