How to Block Websites by Keywords
With HT Parental Controls and its powerful keyword blocker feature, you can effectively block websites that contain specific words in their URLs or titles.
Our keyword blocker allows you to block thousands of sites with a single word or even a phrase. Here’s how to create and use a list of keywords to block for parental control to protect your child’s online experience:
- Download HT Parental Controls and install it on your child’s computer.
- Navigate to Rules > Website Blocking.
- Add the keywords you want to block to the Blocklist.

Note! Use an underscore for keywords to block exact matches and avoid over-blocking. For example, if you add "_bra_", the program will block only this exact keyword. However, if you add "bra" without underscores, it will block all the keywords that contain this combination — brand, bravo, brake, zebra, etc.
How to Set Time Limits for Websites Based on Keywords
HT Parental Controls offers an additional feature: setting time limits for sites with specific keywords.
- Go to Rules > Website Limits.
- Add the keywords you want to limit to the list and select «Limit» for them.
- Set time restrictions or create a schedule.
