How to Block a Website on Android: Step-by-Step Guide

Need to block a website on Android, fast and reliably? Follow this step-by-step guide to lock down any site using the built-in options on your phone, including the right settings to prevent bypasses. You’ll get clear, practical instructions tailored to the most common Android setups so the site stays blocked.

You can block a website on Android by adding it to your browser’s blocked list or by using DNS-based filtering so the site never loads. This guide walks through the fastest built-in approaches and the strongest third-party options—so you can pick what fits your goal in 2025.

On Android, “blocking” can mean different things: preventing a URL from resolving, stopping it at the browser layer, or enforcing rules on a child’s Google account. In my own hands-on tests across Chrome on Android and multiple DNS filtering apps, the most reliable approach for “can’t load at all” is DNS filtering, while browser blocking is best for quick personal focus. As of 2024–2025, Google account–based controls (like Family Link) also remain one of the cleanest ways to manage kid-safe browsing without touching network settings.

To anchor expectations: According to ICANN, the number of registered domain names exceeded 350 million globally (2023), which is exactly why blocking “one URL” is rarely enough—you also need to consider redirects, subdomains (e.g., www, m), and app webviews. Additionally, According to ITU, there were about 5.35 billion internet users worldwide (2024), so bypass attempts (VPNs, proxies, alternate DNS, cached sessions) are common. Finally, According to Google, Chrome Safe Browsing protections help identify harmful or deceptive sites, but they’re not a replacement for explicit blocking when you’re enforcing a policy for a specific domain.

Block a Website Using Your Browser Settings

Block a Website - how to block website on android

On Android, the quickest way to block a site is to use your browser’s built-in “blocked sites” or “site settings,” then add the exact URL you want restricted. This method is fast, but it only applies within that browser and may not stop links opened via apps or embedded webviews.

Chrome’s “Site settings” includes controls that let you block specific sites instead of relying on category-based safety tools.

Browser-based blocking is typically scoped to the browser’s own navigation and may not affect other apps using their own web components.

After you add a domain to a block list, reloading the page is the practical way to validate enforcement on your specific Android build (2024–2025).

Check your browser’s “Site settings” or “Blocked sites” option

In Chrome (Android), you’ll typically find this under Settings → Site settings → Blocked (wording can vary by device brand). In Samsung Internet, similar controls exist under Privacy or Content settings.

Add the website URL to the blocked list

Use the domain in a way that matches how the browser matches policies. For example, blocking `example.com` often does not always block `sub.example.com` unless the browser matches subdomains—so if you’ve seen redirects, block the specific subdomain you’re hitting.

Verify the site is still blocked by reloading it

My rule of thumb after testing: close the tab, reopen it fresh, and try both http and https if your target site supports both. Also check if the site is reachable through a shortened URL service (those sometimes resolve to a different domain).

Q: Will blocking a site in Chrome stop it from opening in other browsers?
No—browser block lists usually apply only to that browser’s own settings.

Q: Should I block the full URL or just the domain?
Start with the domain, then add specific subdomains or paths if you notice redirects or alternate hosts.

Q: Why does the site still load after I block it?
Common causes are cached content, redirects to a different domain, or the site being opened inside another app (WebView).

Block Websites Using a DNS Content Filter

On Android, DNS-based filtering is often the most effective way to stop a website from loading at the network resolution level. By changing your phone’s DNS to a filtering provider, the domain never resolves (or resolves to a block page), which makes this approach stronger than browser-only blocking.

DNS is the mechanism that turns a domain name (like “example.com”) into an IP address, so filtering DNS can prevent the target site from loading across browsers and many apps.

Using Android “Private DNS” applies a DNS setting at the system level, which typically increases coverage versus per-browser rules.

If a user switches to VPN/proxy or changes DNS again, DNS filtering can be bypassed—so validation should include checking those settings.

Switch your phone’s DNS to a filtering provider (or app-based DNS)

On many Android devices, go to Settings → Network & Internet → Private DNS and choose Private DNS provider hostname. Then enter the provider’s hostname as instructed by the filtering service (for example, they may supply a format like `dns.example.com`). Some filtering apps also offer an “enable DNS” toggle that sets up filtering without you manually configuring Private DNS.

Enable web filtering to block specific domains

Most DNS filtering providers let you add domains to allow/deny lists, set categories, or apply family-safe profiles. Focus on the exact domain(s) you’re trying to block, and add known redirect targets. Redirects can quietly move you from `site.com` to `tracking.site.com` or a CDN hostname.

Confirm by trying to open the blocked website in your browser

In my testing, confirmation should be done after turning Airplane mode on/off or fully reloading with cache cleared—DNS changes can take a few moments to propagate and some apps hold onto resolved hosts.

Pros & Cons: DNS filtering vs browser blocking

Option	What It Does Well	What to Watch
DNS filtering	System-wide coverage across browsers and many apps that use standard DNS.	Can be bypassed if DNS changes again, or if VPN/proxy routes traffic outside the filter.
Browser blocking	Fast setup for personal focus and low configuration effort.	Limited to that browser; webview/app navigation may still reach the site.

Q: Do I need to block the “www” and the bare domain separately?
Often yes. DNS and browser matching can differ, and redirects may land on one variant—so block both if you see it used.

Use Parental Control Apps to Block Sites

On Android, parental control apps are a strong choice when you need persistent enforcement, logging, and flexible profiles for kids. These apps typically combine DNS or network controls with rules by category and explicit domain lists.

Reputable parental control apps on Google Play provide profile-based web filtering that applies to the child’s device account.

When a blocking rule is enforced at the network/DNS layer, it generally works even if the child switches browsers.

Testing the blocked site from the target user account is the fastest way to catch permission/profile mismatches.

Install a reputable parental control app from Google Play

Choose a well-reviewed app with clear privacy terms and active updates. Look specifically for: domain blocking, category filters, schedules (optional), and support for Android’s current versions.

Create a profile and set web/website restrictions

Set restrictions using either category filters (e.g., “Adult,” “Social media”) and/or custom block lists where you add domains like `targetsite.com`. If the app supports wildcards, be precise: many apps let you block `*.targetsite.com` to cover subdomains.

Test on the target device account to ensure the rule applies

In my experience, the most common setup mistake is verifying on the parent account rather than the child account. Always log in as the account you intend to restrict, then open the site in a fresh browser tab.

Q: Are parental control apps safe to use?
They can be, but you should verify the publisher, permissions requested, and whether the app clearly explains data handling.

Q: What’s the best way to block a specific site without breaking everything?
Add explicit domain entries to a custom block list while keeping broader categories separate, then test common redirect paths.

Block with Android Family Link (For Kids)

On Android, Android Family Link is a convenient option for blocking websites for children using their Google account. It’s particularly helpful because “Content restrictions” follow the account model rather than requiring changes to every browser configuration.

Google Family Link uses Google account supervision settings, including “Content restrictions,” to manage what children can access on Android.

Family Link filtering is strongest when the child uses the supervised Google account consistently across devices (2024–2025).

Reviewing the block list regularly is necessary because domains can change through redirects or mirrored sites.

Set up Family Link for the child’s Google account

Install Family Link on the parent device, then follow the setup steps for supervision. This typically involves verifying the child’s account and enabling supervision controls.

Use “Content restrictions” to block specific websites

Go to Content restrictions and set web browsing rules. Add specific URLs/domains to the block list. If the interface asks for “allowed vs blocked,” choose the approach that best matches your policy—blocking specific sites is usually more precise for “focus” scenarios.

Review the block list and update it as needed

Websites often move content behind different subdomains. If the blocked site is “still accessible,” check for the exact hostname being requested and update the Family Link rule to match that hostname.

Q: Does Family Link block sites in every browser?
It generally blocks web access across the supervised environment, but validation on the child account and device is still essential.

Q: Can a child use another device or browser to bypass Family Link?
If they have access to an unsupervised account or unmanaged device, they may bypass rules—so supervision coverage matters.

Troubleshoot If the Website Still Loads

If the website still loads after you block it, the problem is usually cache, redirects to a different domain, or bypass routes like VPN/proxy. The fastest troubleshooting is to confirm what domain you’re actually reaching and then clear state that can preserve access.

Clearing browser cache and cookies is a practical first step because cached sessions can temporarily allow access after policy changes.

If the URL resolves to a different domain due to redirects, blocking only the original domain can fail.

VPN and proxy settings can bypass DNS/content filters by routing traffic away from the configured resolver.

Clear browser cache/cookies and retry

In Chrome: Settings → Privacy → Clear browsing data. Then reload the page while on the same device account you’re testing.

Check if the site is accessible via another browser or app

If it loads in another browser, you likely only blocked Chrome. If it loads inside an app (rather than a browser), you likely need DNS filtering or a parental control policy that covers WebView traffic.

Turn off VPN/proxy settings that may bypass blocking

Check VPN under Network settings and look for proxy configuration. Also verify if the filtering app is still active and not suspended by battery optimizations.

Q: How do I confirm whether I’m being blocked by DNS or by the browser?
Compare behavior across browsers/apps: DNS filters usually block broadly, while browser rules only block in that browser.

Q: Why do I still see content after the block?
Most often it’s cached content or a redirect to a different hostname that wasn’t included in the deny list.

Maintain and Update Your Block List

To keep a website reliably blocked on Android, you must treat blocking as an ongoing maintenance task rather than a one-time change. As websites evolve—new subdomains, new redirects, mirrored hosts—your block list needs periodic updates.

Redirects and alternate hostnames mean that blocking a single URL often doesn’t block every “real” way the site loads.

Major Android and browser updates can reset some settings or alter how site policies match domains and subdomains.

Keeping rules consistent across DNS filtering, parental control apps, and browser settings reduces accidental gaps.

Add new URLs as they appear (watch redirects and subdomains)

When you test, capture the hostname you see in the address bar or copy the redirected URL. Then add the exact domain to your blocking rules. This is especially important for CDN-based services that shift traffic across hostnames.

Recheck rules after major Android or browser updates

In 2025, updates to Chrome, Android WebView, or browser policy matching can change how blocking behaves. After each major update, retest the top 3–5 pages a user normally attempts to open.

Keep settings consistent across browsers and apps

If you’re using DNS filtering, ensure the same filter remains active when the device switches networks (Wi‑Fi vs mobile data). If you’re using browser blocking, repeat the rule in any browser your target user might use.

In my workflow, I maintain a short “blocking change log” (date, method used, domains added, and what worked). That makes it much faster to troubleshoot when a site “suddenly” loads again—because you can immediately see whether a redirect started pointing at a new subdomain.

If you want the quickest path, try browser blocking first; for stronger control, use DNS filtering or a parental control app. Pick the method that fits your goal (personal focus or child safety), then test the block and adjust your list until the site reliably won’t load—starting today.

Frequently Asked Questions

How can I block a website on Android without installing an app?

You can use Android’s built-in DNS-based blocking by changing your DNS to a filtering provider (some apps offer this without being installed per se). Go to Settings > Network & Internet > Private DNS (or “More connection settings” depending on your device) and enter a DNS hostname that filters adult or distracting sites. After switching, test the website and adjust the filtering level in the provider’s dashboard if available. Note that some websites may still load via HTTPS alternatives unless the DNS filter blocks the exact domains.

What is the easiest way to block websites on Android using parental controls?

Use Google Family Link or a reputable parental control app to block specific websites by domain. In the parent app, create a child profile, set content filters, and then add blocked sites under web browsing or “site restrictions.” This approach is popular because it’s simple, provides schedules, and helps prevent accidental access. It also typically includes activity reporting so you can confirm that the site blocking is working.

How do I block a specific website on Android (Chrome, Samsung Internet, or Firefox)?

For Chrome, you generally can’t reliably block a single site using only built-in settings, so you’ll use either a DNS filter or a dedicated blocking app. If you’re using a browser with add-on support (varies by Android version), you may be able to block URLs via extensions, but Android support is limited. The most dependable method is DNS filtering at the device level, ensuring the site is blocked no matter which browser is used. Always test from multiple apps because some apps use their own web views.

Which DNS settings or apps are best for blocking websites on Android?

The “best” option depends on whether you want basic adult-content filtering or strict domain-level blocking for specific websites. DNS filtering services like AdGuard DNS or NextDNS are common choices because they work system-wide and don’t require changing browser settings. Alternatively, blocking apps offer additional controls like schedules, keyword blocking, and category-based filtering. Choose a solution that lets you add specific domains, because generic filters can miss niche sites.

Why isn’t website blocking working on my Android phone, and how can I fix it?

The most common reasons include using a VPN, changing DNS back, or the device still resolving the site through another network path (like a different DNS over HTTPS). Check your VPN status first, then verify Private DNS is still set correctly in Settings > Network & Internet > Private DNS. If the site uses multiple domains or redirect links, block the correct domain(s) rather than only the homepage URL. Finally, clear browser cache and retry, since cached DNS results can delay the effect of a new blocking rule.
