What blocking a page means and why you'd do it
Blocking a page on Chrome means telling your browser to hide a specific website from your search results and prevent it from loading when you click a link to it. Chrome does not have a built-in "block this site" button in the way some other browsers do, so the method depends on what you actually want to stop: hiding search results, stopping a site from opening, or preventing it from tracking you.
Most people block a page because they keep landing on it by accident in search results, or because a site keeps trying to load ads or notifications they do not want. The steps are different for each situation, and Chrome offers a few separate tools rather than one unified blocking feature.
Key Takeaways
- Chrome does not have a single "block this website" feature, but you can hide sites from Google search results using the search settings menu.
- To stop a website from sending notifications or pop-ups, you can change Chrome's permission settings for that specific site.
- If you want to prevent a site from loading at all, you will need a browser extension, since Chrome's built-in tools only hide or restrict, not fully block.
- Blocking a site in Chrome only affects your own browser — it does not block the site for other people or prevent the site from existing.
Hide a website from your Google search results
If you keep seeing the same website in your search results and want it gone, you can tell Google to stop showing it to you. This is the most common reason people want to block a page, and it is the easiest to do in Chrome.
Search for something as you normally would. In the search results, find the site you want to hide. Click the three vertical dots (the menu button) next to that result. Select "Don't show results from [website name]" from the menu that appears. Google will when ready remove that site from your current search results and remember your choice for future searches.
If you change your mind later, you can undo this. Go to Google Search Settings (search for "search settings" in Google, or find it in your Google account menu). Scroll down to "Excluded websites" and you will see a list of every site you have hidden. Click the X next to any site to start seeing its results again.
Stop notifications and pop-ups from a specific website
Many websites ask permission to send you notifications or show pop-ups. If you have said yes to a site and now regret it, you can revoke that permission without blocking the entire site.
In Chrome, click the lock icon or the info icon (an "i" in a circle) that appears to the left of the website address in the address bar. A small menu will open. Find "Notifications" or "Pop-ups" in that menu — whichever one is causing the problem. Click the dropdown next to it and change the setting from "Allow" to "Block". The site will no longer be able to send you notifications or pop-ups.
You can also manage all of a site's permissions this way. The same menu controls whether a site can access your location, your camera, your microphone, or your clipboard. Change any permission from "Allow" to "Block" and the site loses that access when ready.
Prevent a website from loading with a browser extension
If you want to completely prevent a website from opening — so that clicking a link to it does nothing, or the page shows an error — you will need a browser extension. Chrome does not offer this as a built-in feature, but several free extensions do the job.
BlockSite and LeechBlock NG are two popular choices. To use either one, go to the Chrome Web Store (search for it, or go to chrome.google.com/webstore). Search for the extension by name. Click "Add to Chrome" and confirm when the popup asks. The extension will install and add an icon to your toolbar.
Open the extension and look for a button or field to add a blocked site. Type the website address (for example, reddit.com or twitter.com) and save. From that point on, if you try to visit that site, the extension will stop the page from loading and show you a message instead. You can add as many sites as you want, and you can remove them from the extension's settings whenever you choose.
Block a site on a shared computer or for another user
If you are setting up Chrome for someone else — a child, for example — and you want to prevent them from visiting certain sites, you have a few options depending on who owns the computer.
If the computer belongs to you and you are setting up a separate user account for someone else, you can use Chrome's parental controls. Go to your own Chrome account settings, find "Manage other people" or "Family Link", and set up supervised browsing for that account. You will then be able to block sites from your own account, and those blocks will explore when the other person uses their account on that computer.
If the computer itself belongs to someone else, or if you do not have administrator access, you can only block sites within your own Chrome profile. Install a blocking extension (like BlockSite) in your profile, and it will only affect your browsing — other people using the same computer will not see those blocks.
What blocking does and does not do
It is important to understand the limits of blocking. When you block a site in Chrome, you are only changing what happens in your own browser on your own computer. The website still exists, other people can still visit it, and the site's owner has no way of knowing you blocked them.
Blocking a site does not delete your browsing history with that site, does not remove your account from that site, and does not prevent the site from appearing in links shared by other people. If someone sends you a link to a blocked site, clicking it will still trigger your block (the page will not load, or you will see a block message). If you want to visit the site again, you will need to unblock it first.
Frequently Asked Questions
Can I block a website on my phone using Chrome?
Yes, but the process is slightly different. Tap the three-dot menu in Chrome, go to Settings, then Site Settings, and find the site you want to block. You can change its permissions (notifications, pop-ups, location) the same way you would on a computer. To hide search results on mobile, use the same method as desktop: tap the three dots next to a search result and select "Don't show results from this site".
If I block a site, will it know I blocked it?
No. The website has no way of knowing whether you blocked it in Chrome, hid it from search results, or straightforward never visited. Blocking only affects your browser — it does not send any signal to the website or its owner.
What is the difference between blocking and deleting browsing history?
Deleting your browsing history removes the record that you visited a site, but does not prevent you from visiting it again in the future. Blocking prevents the site from loading or appearing in search results, but does not erase the fact that you visited it before. You can do both: delete your history and then block the site.
Can I block a website for everyone who uses my computer?
Only if you set up parental controls through a family account, or if you have administrator access and install blocking software at the system level (not just in Chrome). A blocking extension installed in your Chrome profile only affects your account on that computer.
Will blocking a site in Chrome also block it in other browsers?
No. Chrome's blocking features only work in Chrome. If you use Firefox, Safari, or Edge, you will need to set up blocking separately in each browser. Some extensions work across multiple browsers, but Chrome's built-in search result hiding and permission controls do not.
