Why Block Websites? {#why-block-websites}
23 Minutes
Average refocus time after digital interruption.
Source: Gloria Mark, âAttention Spanâ (2023)
Blocking websites removes the need for constant willpower. Instead of resisting temptation every time you see a distracting tab, you set a rule once and let technology enforce it.
The Science Behind It:
Research from the University of California, Irvine (Gloria Mark, 2023) shows that it takes an average of 23 minutes and 15 seconds to fully refocus on a task after an interruption. Frequent digital interruptions significantly reduce cognitive performance.Â

Method 1: Using a Website Blocker Extension (Recommended)
A browser extension is the fastest and most flexible way to block websites on Chrome.
â User-friendly interface
â Scheduling capabilities
â Incognito mode support
â Works only in the browser
â Can be disabled by tech-savvy users
â May not block content in other apps
Install a Website Blocker Extension â Go to the Chrome Web Store and search for a reliable website blocker. Choose one with high ratings (4.5â
+) and positive reviews.
Add Websites to the Block List â Open the extension and add 5-10 sites that reliably derail you. Start small and expand later.Â
Customize Schedules â Set work hours (e.g., 9 AM to 5 PM) when blocks should be active. Allow access during evenings and weekends.Â
Enable Password Protection â Activate password protection to prevent impulsive disabling.Â
Enable Incognito Mode Protection â Make sure the extension can block websites even in incognito mode.
If you only need to block distracting websites on your personal Chrome browser, this is the method we recommend. Itâs fast, free, and offers the most control.
Method 2: Using Google Family Link (For Parental Control)
For parents who want to restrict web access on their childâs device, Google Family Link is a robust, free option.Â
â Applies across all Chrome browsers on the childâs account
â Syncs with other parental controls
â Requires creating a Google account for the child
â Only works within the Google ecosystem
Download Family Link and create a Google Account for your child.
Select your childâs profile and go to âControls.â
Under âGoogle Chrome and Web,â choose âManage sitesâ and add specific URLs to a âBlockedâ list.
Family Link automatically enforces SafeSearch for users under 18 and blocks Incognito Mode.Â
Method 3: Editing the Hosts File (For Advanced Users)
For advanced users who want to block websites on Chrome and all other browsers, the hosts file method provides system-wide blocking.Â
â System-wide (all browsers)
â Permanent until manually removed
â Requires technical knowledge
â No password protection
â No scheduling capabilities
â Can be bypassed by tech-savvy users
Open Notepad as Administrator.
Navigate to C:\Windows\System32\drivers\etc and open the hosts file.
Add: 127.0.0.1 www.example.com (replace with the website you want to block).Â
Save and flush DNS: ipconfig /flushdns in the command prompt.Â
How to Block a Website on Android {#android}
Yes. On Android, download a blocker app from the Google Play Store. These apps block both websites and apps, with features like blocking distracting notifications, setting focus sessions, and gaining insights into your usage patterns. Setup takes about 3 minutes.
