Advantages of using a keyword blocker

There are several methods to restrict websites, such as blocking specific sites (e.g., youtube.com) or limiting a category (e.g., adult sites). Compared to them, blocking websites based on keywords has two common advantages.

• If you want to prevent children's or your own access to certain websites, you can manually them to the block list one by one. But what if it's a long list? Adding individual sites can be time-consuming. On the contrary, a keyword blocking tool can automatically detect blocked keywords in URLs and apply blocking accordingly, saving you a lot of manual effort.
• Blocking websites by category can be efficient. However, it doesn't cover all websites of a certain category. In addition, many new websites are created every day. In such cases, blocking websites by keyword (e.g., porn, casino) may be more comprehensive.

(In addition, there's still a type of keyword blockers, which can identify blocked words in page content and automatically block or hide the words, instead of blocking access to the website or page.)

Top 4 keyword blockers: Reviews and instructions

After testing, I picked up three best tools to block sites by keyword and one tool for blocking keywords themselves.

1. Cisdem AppCrypt

Cisdem AppCrypt is a website blocker and app locker designed for productivity, parental control, and digital wellbeing. It offers multiple ways for users to easily block sites on popular web browsers, including block sites by keyword, block sites by category, and quickly add specific sites to block.

Its keyword blocking function is flexible. Add the word or phrase to the block list. It will automatically block all URLs that contain this keyword on the Internet. For example, block the keyword “game” using this tool, then all these websites will be blocked:

• www.gamessumo.com
• www.halfbrick.com/games/fruit-ninja-classic
• x.com/FortniteGame
• www.facebook.com/groups/gameplay1122
• www.reddit.com/r/game

But it only allows you to add up to 2 words to block. If you need to block more keywords, you can upgrade to the premium plan, which costs $10.99 per month.

Some routers offer features for you to block sites containing specific keywords in the URLs or content. This method is particularly useful for parental control.

Steps to block sites by keyword using keywords filter on router

Step 5. Enter the words or phrases you want to block.

Step 6. Save your settings.

4. Word Blocker

Word Blocker is a Chrome extension provided by Papillon Software. Unlike the three tools above, this tool is designed to block keywords themselves, not a website or page. Despite the difference, these tools may serve the same purposes, such as parental control.

Steps to set up this keyword blocker on Chrome

Step 1. Search for "Word Blocker - Text Redaction & Pattern Filter" in the Chrome Web Store.

Step 2. Add the extension to your browser.

Step 3. Click the extension's icon in your browser's toolbar.

For example, after you add a word, like "nude", "torture", or "murder", the word will be replaced by a solid color block whenever it appears on a web page. You can also block a phrase, e.g., "teen sex" or "kim kardashian".

Lists of keywords you should block

The Internet makes our life more convenient, but there are also potential risks when using it. Blocking specific keywords can help us avoid interference from bad content, boost productivity, and keep network safe. Here are some keywords that are recommended to be blocked for parental controls, productivity, and online safety.

For parental controls

Families with children often worry about their children being exposed to inappropriate content online. Using a keyword blocker, parents can effectively control their children's online activities.

For productivity

When working or studying, there are many interesting websites on the Internet that can distract us. Blocking some keywords that are not related to work or study, such as social media, games, etc., can boost our productivity.

For online safety

In order to enhance online safety, these keywords related to potentially harmful content should be blocked.

Conclusion

Website blocking by keyword is a good way to restrict access to bad or inappropriate websites effectively. Simply add a word or phrase to the block list, and then a large number of websites will be blocked automatically. This article shares with you four  different tools. I hope it helps.
