How to Blacklist Websites on Google Chrome: A Complete Guide (Windows, Mac, Android)

Whether you’re a parent trying to protect your children online, a student looking to stay focused, or someone managing productivity, blocking websites on Chrome can be an incredibly useful tool. Chrome doesn’t offer built-in website blocking, but there are multiple methods—from extensions to system-level solutions.

In this detailed tutorial, we’ll explore how to blacklist websites on Google Chrome using different tools and platforms.

📌 Method 1: Use Chrome Extensions (Windows & macOS)

The easiest and most user-friendly way to blacklist websites on Chrome is through browser extensions. Here’s how:

✅ Step-by-Step: Using the “BlockSite” Extension

1. Open Chrome Web Store.

2. Search for BlockSite – Website Blocker for Chrome.

3. Click Add to Chrome and then Add Extension.

4. After installation, click the BlockSite icon near your address bar.

5. Go to the BlockSite dashboard and add URLs to your Blacklist.

6. You can also set schedules and block adult content with one click.

Pros:

• Simple interface

• Scheduling and focus mode

• Password protection

Cons:

• Advanced features may require a premium version

📌 Method 2: Edit the Hosts File (Windows & Mac – Blocks All Browsers)

If you want to block websites system-wide (not just in Chrome), you can modify the hosts file.

🖥️ Windows Instructions

1. Open Notepad as Administrator.

2. Go to:
   C:\Windows\System32\drivers\etc\hosts

3. At the bottom of the file, add:

   127.0.0.1 www.facebook.com 127.0.0.1 facebook.com

4. Save the file and restart your browser.

🍎 macOS Instructions

1. Open Terminal.

2. Type:

   bash
   sudo nano /etc/hosts

3. Add lines like:

   127.0.0.1 www.youtube.com 127.0.0.1 youtube.com

4. Press Control + O to save and Control + X to exit.

5. Flush DNS:

   bash
   sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder

📌 Method 3: Set Up Parental Controls (Chrome Supervised Users or Family Link)

If you’re managing your child’s browsing, Google provides Family Link to block or approve content.

👨‍👩‍👧‍👦 Using Family Link:

1. Download Family Link app on both parent and child devices.

2. Link your child’s Google account.

3. Go to Manage Settings > Google Chrome.

4. Choose:

   • Allow All Sites

   • Block Mature Sites

   • Only Allow Approved Sites

5. Add specific websites to block or allow manually.

Ideal for parents who want remote control over browsing activities.

📌 Method 4: Use a Router to Block Sites for All Devices

Blocking sites at the router level affects all users and devices on the network.

⚙️ Steps (May Vary by Router Model)

1. Log in to your router’s dashboard (usually at 192.168.0.1 or 192.168.1.1).

2. Enter your credentials.

3. Go to Parental Controls, Firewall, or Access Restrictions.

4. Add blacklisted domains (e.g., tiktok.com, instagram.com) under blocked URLs or keyword filter.

5. Save and restart your router.

For details, check your router’s manual or support page.

📌 Method 5: Use Chrome Developer Policies (Enterprise/School Use)

This method is best for organizations that manage devices via Google Workspace Admin Console.

1. Go to Chrome Enterprise Admin.

2. Navigate to Devices > Chrome > Settings > Users & Browsers.

3. Scroll to URL Blocking.

4. Add blocked domains under:

   • URLBlacklist for denied sites

   • URLWhitelist to allow exceptions
