Key Takeaways

To block specific keywords from being searched on Google, use Cisdem AppCrypt, which is easy to set up and difficult to bypass.

To block certain content from being appearing in search results, use SafeSearch or uBlacklist, depending on your specific needs.

Thanks to Google, the internet is just a search away. However, it's not always a good thing. For example, you may want to stop your children from searching for inappropriate content. You may also want to block certain content from appearing in search results. 

In this article, I will cover both situations and show you how to block searches on Google in four ways. You will find the article helpful, whether you are doing this for a loved one or yourself.

 

Method 1. How to block searches on Google with AppCrypt

Applies to: Mac, Windows, and Android

This method uses Cisdem AppCrypt, an easy-to-use website blocker and app locker in one. You only need to add the search terms that you want to block on Google, and AppCrypt does the rest.

Once a word or phrase is added to the block list, every time you or someone else searches for it, Google will immediately block the search on Chrome, Edge, and all other supported browsers, and no search results will show up at all. At the same time, other search terms are still allowed on Google.

In addition to Google, this specific search will be blocked on Bing, Facebook, X, and more platforms.

The following steps show you how to block a search on Google using this tool.

1. Download and install AppCrypt on your computer or phone.

Free Download macOS 10.12 or later Free Download Windows 10 or later

Download on theApp Store GET IT ONGoogle Play

2. When you open it for the first time, set a password. It’s recommended to select the Launch at System Startup checkbox.

Tip To block yourself from searching certain words on Google, you can ask a trusted person, such as a family member, to set the password for you. If you are doing this for your children or senior parents, make sure that they can't easily guess the password.

3. On a Mac, click the lock icon in the menu bar to choose Open Main Window. On a Windows PC, click the AppCrypt icon in the taskbar.

4. Enter the password to access the main window.

5. Under the Web Block tab, enter the specific word that you’d like to block in the URL field and click Add. Add more words if needed.

In step 5, if you have a text file with a list of words to block on Google, you can import the file by choosing Import > TXT file. This can save you from manually adding words.

From now on, Google won’t let you or other users of this computer search the added words. Also, any URL containing any of the added words will be blocked and inaccessible.

If blocking certain searches on the search engine isn’t enough, you can use AppCrypt to block more. Here’re some examples.

  • Block specific websites and pages, like distracting ones or inappropriate ones
  • Block a certain category of websites, like adult sites or social media sites, by choosing the category from the Import menu
  • Block all websites except a few

By default, a search or website will be blocked permanently as long as AppCrypt is running. There are 3 ways (including quitting AppCrypt) to unblock a search, but they all require the password. So only people who know the password can unblock searches.

 

Method 2. How to block a search on Google with BlockSite

Applies to: Mac, Windows

BlockSite is a web browser extension. Once you add a search term to its Block List, if you search the term on Google, this extension will block Google, preventing you from seeing the search results for this term. This extension is available for Chrome, Firefox and Edge. The blocking only applies to the very browser on which this extension is installed.

Below is how to use this extension to do the blocking.

1. Add BlockSite to your browser.

2. Click the Extensions icon in the upper right corner. Select BlockSite. Click the settings iconthe settings icon.

3. Choose Block Sites in the sidebar on the left to access the Block List.

4. Click Add to Block List.

5. Choose the Keywords tab.

6. Enter the word you need to block. The word will show up in the Keywords to Block list. Click the Add button next to the word. Add more words if needed.

7. Click Done.

With Method 1, searches are blocked on Google in both normal browsing and incognito/private browsing. But by default Method 2 only supports normal browsing. To make it support incognito/private browsing, you need to enable the extension to work in such browsing.

 

Method 3. How to block inappropriate search results on Google

Applies to: Mac, Windows, Android, iPhone

The two methods above are about blocking search terms and can be suitable for scenarios like this: you are a concerned parent with a teen son who uses Google to search for porn. You just need to block search terms like “porn”.

Method 3 can also be helpful for parental control. However, it doesn’t block a search. It blocks inappropriate search results instead.

This method uses Google SafeSearch. Once turned on, SafeSearch automatically blocks inappropriate content (like adult websites and explicit images) in search results.

Blow is how to turn it on.

1. In your browser, go to https://www.google.com/safesearch.

2. Choose Filter (recommended) or Blur.

  • Choosing Filter will hide explicit links in search results, text and images.
  • Choosing Blur will blur explicit images in search results, which is generally not enough.

It’s that simple.

Note that turning on SafeSearch in normal browsing doesn’t turn it on in incognito/private browsing, and vice versa. You need to turn it on in both browsing modes.

To turn on SafeSearch in the Google app on your Android device, iPhone or iPad, you need to go to the app’s settings.

 

Method 4. How to block specific websites from Google search results

Applies to: Mac, Windows, iPhone

Some seemingly normal search terms (or typos) can bring up explicit websites. Also, results from some unwanted websites may keep showing up in your searches. Method 4 can help you easily avoid such things.

This method uses an extension called uBlacklist. Once set up properly, it can help you block those inappropriate or annoying search results on Google.

Here are the steps.

1. Add uBlacklist to your Chrome, Firefox, or Safari browser.

(I use Chrome as an example in the rest steps.)

2. Right-click the extension's icon in the toolbar and choose Options, which will open the settings page.

3. In the General section, add unwanted websites one by one. Then, click Save.

General section

Note The last step can be a bit tricky. For example, to block Google search results from YouTube, you can't simply adding "youtube.com". Instead, you need to adding "*://*.youtube.com/*". If you don't follow this rule, the block list won't work. If, for example, you want to block search results from all popular social media sites, you can ask an AI tool to generate the list for you. Just tell it the rule, and then do the copy and paste.
