You might want to block a website on your Android phone now to keep away from distracting pages and URLs that contain viruses or inappropriate content.

Websites are easy to blacklist no matter what your purpose is. In this guide, we teach you several ways of how to block a website on Android.


Blocking Websites on Android Browsers

There is no built-in function to block websites on an Android phone so you have to do it per browser. The process takes just a few steps or clicks. Let’s now focus on the easiest methods for mainstream mobile browsers.


How to Block a Website on Chrome

Google Chrome is one of the most popular browsers for smartphones, with more than 5 billion downloads on Android devices. There are two ways you can block websites on Chrome on Android.


Via Safe Browsing

To block websites on Chrome, you have to enable “Safe Browsing,” a built-in function that screens out dangerous websites. It does not let you dictate what URLs to block, though.

Via Third-Party App

To block a specific website on Google Chrome, you need to download an app. Here we discuss BlockSite, one of the most widely-used website blockers for Chrome and other mainstream browsers. The app is also versatile for it allows you to set specific blocking schedules.

On average, people spend over two hours daily on social media, according to Smart Insights. This figure is increasing during the pandemic and could be higher depending on the country.

Social media is one of the top hindrances to productivity. This is why you might have to block it. It eats up the time you can spend with others or for yourself offline and sometimes takes over your more important daily tasks. Win over social media addiction and burnout by blacklisting such websites and managing your screen time.


Video Streaming Websites

Watching shows and movies on websites is also an activity that takes up a big chunk of mobile usage duration. People who enjoy it even do movie marathons which may last half a day or longer. Moreover, time spent on streaming shows and movies on mobile phones during the second quarter of this year rose by 25 percent from the last quarter of 2019, per App Annie as reported in Media Play News.

Like social media, streaming websites and apps can reduce daily productivity so you can also block those websites to have more time for other things.


Adult and Violent Websites

It is a given that these types of websites are top-of-mind picks for parents to block. While some websites have personnel removing adult-only content and gore, there are still slim chances when these are picked up seconds before they are taken down.

As a parent or someone who does not want such content, you might want to block possible websites where these usually happen to avoid that slim chance.


Malware and Phishing Websites

These two kinds of webpages are must-block sites for everyone that’s why many mobile browsers and security apps have the filters for these by default.

The malicious software from websites can harm your devices and networks. Phishing websites trick you into providing sensitive information that may result in your identity being stolen or your bank accounts hacked. Website blockers and mobile security apps are your second layer of protection from those.


Online Shopping Websites
