How to Block a Website on Google Chrome

Blocking a website in Google Chrome can help you avoid distractions, manage screen time, or control which websites children can visit. Although Chrome does not include a dedicated website-blocking setting, several other methods can help you restrict access to specific websites.

You can use a browser extension, Google Family Link, Windows settings, or your home router. The right choice depends on whether you want to block a website for yourself, protect a child, or restrict access across multiple devices.

Different Ways to Block Websites in Chrome

Here are four common methods you can use:

• Chrome extension: A simple option for blocking selected websites while browsing.
• Google Family Link: Useful for managing website access for children.
• Windows Hosts file: Helps restrict access to specific domains on one Windows computer.
• Router or DNS filtering: Can block selected websites across devices connected to your home network.

Let’s look at each method step by step.

Method 1: Block a Website Using a Chrome Extension

A website-blocking extension is one of the easiest options for Chrome users. Extensions such as BlockSite offer tools for restricting access to selected websites.

Follow these steps to get started:

1. Open Google Chrome on your computer.
2. Visit the Chrome Web Store.
3. Search for a website-blocking extension, such as BlockSite.
4. Review its ratings, permissions, and privacy information.
5. Select the extension and click Add to Chrome.
6. Confirm the installation when Chrome asks for permission.
7. Open the extension using its icon near the address bar. If you cannot see it, check the Extensions menu.
8. Enter the website address you want to restrict and add it to the block list.

Once configured, the extension can prevent access to websites on its list. Some extensions also offer scheduling features, which can be useful if you want to limit access to social media during work or study hours.

Keep in mind that extensions are developed by third parties. Their features and privacy practices can vary, and someone with access to your computer may be able to disable or remove them.

Method 2: Block Websites for Children With Google Family Link

Google Family Link helps parents manage certain online activities on their children’s devices. If your child uses Chrome while signed in with a supervised Google account, you can manage website access through the available parental controls.

Here is how to set it up:

1. Open the Google Family Link app on your phone.
2. Select your child’s profile.
3. Open Controls.
4. Find the Google Chrome and web settings.
5. Look for the section that manages approved and blocked websites.
6. Choose the option to add a website to the blocked list.
7. Enter the website address you want to restrict, then save your changes.

The available options may vary depending on your child’s account, device, and current Family Link settings.

For example, you might block a website that you do not want your child to visit or allow only websites that you have reviewed.

Important: Google states that these restrictions apply when the child uses Chrome while signed in with the supervised account. They should not be treated as a guarantee that the website is inaccessible through every browser or device.

For the most accurate instructions, consult Google’s official Family Link help resources.

Method 3: Block a Website on Windows Using the Hosts File

Windows includes a system file called the Hosts file. It can associate domain names with specific IP addresses, allowing you to restrict access to selected domains on your computer.

This approach does not require a Chrome extension, but it does require administrator access and careful editing.

Step 1: Open Notepad as an Administrator

Open the Windows Start menu, search for Notepad, right-click it, and select Run as administrator.

Approve the permission request if Windows displays one.

Step 2: Open the Hosts File

In Notepad, choose File > Open and navigate to this location:

C:\Windows\System32\drivers\etc\hosts

Change the file-type filter to All files so that the Hosts file appears in the file browser.

Select the file and open it.

Step 3: Add the Website Domain

At the bottom of the file, add an entry for the domain you want to restrict.

For example, to target example.com, you could add:

127.0.0.1 example.com

If the website also uses the www version, add a separate entry:

127.0.0.1 www.example.com

Replace the example domain with the website you want to block.

Some websites use additional subdomains, so blocking the main domain may not restrict every related address. This method also does not provide the same level of filtering as a dedicated parental-control solution.

Step 4: Save the Changes

Save the file and reopen Chrome to test whether the restriction works. If necessary, restart the browser or refresh the system’s DNS cache.

A Hosts file entry can affect how the specified domain is resolved across browsers on that Windows computer, including Chrome, Edge, and Firefox. However, results may vary depending on DNS settings, browser features, and how the website is accessed.

Edit this file carefully. Incorrect changes can interfere with normal network access.

Method 4: Block Websites Across Your Home Network

If you want to restrict a website on several devices, configuring your router or a DNS filtering service may be a better option.

Depending on the setup, this approach can help apply website restrictions to phones, tablets, computers, and other devices using your home network.

Using Your Router’s Parental Controls

Many home routers provide website filtering, parental controls, or access restrictions.

To check whether yours supports this feature:

1. Open your router’s administration page or companion app.
2. Sign in using your administrator credentials.
3. Look for settings named Parental Controls, Website Filtering, or Access Control.
4. Add the website or domain you want to restrict.
5. Save the settings and test the restriction on a connected device.

The exact process depends on your router’s manufacturer and model. Check its official manual if you cannot find the relevant option.

Using a DNS Filtering Service

Another option is a DNS filtering service that lets you create rules for websites or categories of online content.

Depending on the service, you may be able to configure filtering on your router or individual devices. Router-level settings can cover more devices on the network, while device-level settings apply only to the devices where they are configured.

However, network-level restrictions may not work when a device switches to mobile data, uses a different network, or bypasses the configured DNS service.

Final Thoughts

Blocking websites in Google Chrome is possible even though the browser does not offer a dedicated setting for every website. Browser extensions provide a straightforward starting point, while Family Link, the Windows Hosts file, and network filtering offer alternatives for different situations.

Before choosing a method, consider who needs the restriction and how widely it should apply. Reviewing the available settings and testing the result will help you select a practical solution for your browsing needs.
