Can I block adult websites via router?
Some routers have parental controls. If your router is one of them, you should be able to block access to certain websites such as porn related websites by configuring router settings.
Here I will use a TP-Link router to show you the process. The settings and steps can be different depending on the router you use.
1. Open a web browser.
2. Access router settings.
3. Go to Advanced settings.
4. On the left, scroll down and choose HomeCare. Choose Parental Controls.
5. Create a profile for your kid.
6. Modify the profile and choose Filter Level.
7. Choose a level. If you set the profile to be for a child, preteen or teen, your router will automatically block adult content.
Can I block adult websites via SafeSearch?
If you block access to inappropriate websites, they will become inaccessible, and it won’t be possible to access the videos, images and other content on them. But what if it is not enough?
We use search engines everyday, so do many children. If a child misspells a certain search query, horrible search results (such as porn sites and explicit images) could show up.
To prevent this from happening, parents can turn on Google SafeSearch.
1. Go to Google.
2. Click Settings in the bottom right corner and choose Search settings.
3. Select the box next to Turn on SafeSearch.
4. Scroll down and click Save.
When you return to Google.com, a message will appear saying Explicit results filtered with SafeSearch. This can help prevent children from stumbling upon bad search results.
In addition to Google, other popular search engines such as Bing, Yahoo and DuckDuckGo also have the SafeSearch feature.
