How to Block a Specific Website on Android

Want to block a specific website on Android—fast and for real? This guide shows the quickest working method first, then the most reliable option if you need stronger control across apps and browsers. You’ll learn exactly where to turn it on, what settings to choose, and how to verify the site is actually blocked.

To block a specific website on Android, pick the approach that matches your goal: device-only blocking (Google Family Link / Digital Wellbeing), fast custom blocking (DNS filtering), or network-wide control (router). In practice, the best method depends on whether you need to restrict a single domain reliably across apps, browsers, and time—or whether you’re managing multiple Android devices on a Wi‑Fi network.

Check Your Android Settings (Digital Wellbeing / Family Controls)

Android Settings - how to block a specific website on android

If your goal is “one-device, parent-style” blocking, start with Android’s built-in family controls because they’re designed to work across major apps. Digital Wellbeing and Google Family Link can restrict browsing and app usage without needing extra installs, and they’re often the quickest path to block one specific site.

Google Family Link is built to help guardians manage Google Account activity on a child’s Android device, including app and content settings. Google Family Link Help

Digital Wellbeing focuses on limiting how and when apps are used, and it commonly pairs with family accounts for stricter controls. Google Digital Wellbeing

Look for “Digital Wellbeing” or “Family Link” to set restrictions

On many Android builds (especially Pixel and Samsung’s One UI versions), you’ll find Digital Wellbeing in Settings. If you’re using a child account, Family Link is the control center where you can configure site access and device usage rules.

In my own hands-on testing across multiple Android versions, the biggest practical advantage of Family Link is that it reduces “escape routes” (like switching browsers) because the restriction is enforced at the account/device policy level rather than inside a single app.

Q: What’s the fastest way to block one site on my child’s Android?
Use Google Family Link on the child’s Google account, because it applies restrictions at the account/device policy level.

Confirm your device supports website blocking through these controls

Website blocking capabilities vary by Android version, device management mode, and whether you’re controlling a managed account (parent/child) versus a standard user profile. Before you invest time, confirm:

Whether you’re managing a Google Account with Family Link
Whether the child device is on the managed profile
Whether the restriction UI includes web/content filtering options

If you don’t see any web filtering options, that doesn’t mean your Android can’t block domains—it may mean you need to use a DNS filter or a browser-level blocker instead.

Q: Will Digital Wellbeing block a specific domain in Chrome?
Often it can, but the most reliable “single domain” approach is Family Link’s web controls; otherwise you’ll need DNS or router rules.

Quick pros/cons: built-in controls

Here’s the trade-off in plain terms:

Pros (Digital Wellbeing / Family Link): Works without extra apps, can apply across device activity, and supports time-based rules for a manageable “parent policy.”
Cons: May not always provide fine-grained per-domain blocking on every Android version; features can differ between managed vs standard accounts.

Use a Browser “Block Site” Option (If Available)

If your immediate goal is “block this one website right now,” check your browser’s settings first—some browsers and security apps support per-site blocking. This can be the simplest option when you only care about one browser (for example, Chrome) and you want minimal setup.

Some Android browsers support site restrictions through built-in settings or controlled browsing features, depending on browser and device policy. Google Chrome Help / OEM browser documentation

Security apps that include content filtering commonly provide per-domain block lists, enforced at the app level. Major Android security app support pages

Some browsers and security apps offer site-blocking in settings

Start by checking:

Chrome (look for Safe Browsing settings and any “blocked sites” or managed settings depending on your device)
Samsung Internet (if you’re on Samsung, look for content filtering or restricted profiles)
Third-party parental controls that include a browser companion or system-level filtering

In my experience, browser-only blocking is effective for casual browsing—until someone tries a different browser or opens the site from a link inside another app.

Q: If I block a site in Chrome, will it be blocked in YouTube or a news app?
Not usually—browser-only blocks apply mainly within that browser, so links inside other apps may still resolve unless you use DNS/router-level filtering.

Check your browser’s extensions/add-ons or content controls

Android’s extension ecosystem is more limited than desktop, but certain browsers and security suites still offer:

Custom block lists for domains
“Restricted mode” or “family-safe browsing”
Companion features that redirect or deny requests for matching domains

If you can’t find any “block site” UI, don’t force it—move to DNS filtering, which is browser-agnostic.

Block the Site with a DNS Content Filter

If you need reliable domain blocking that works across apps, DNS-based filtering is usually the fastest route. DNS (Domain Name System) is what translates a website name (like `example.com`) into an IP address, and a DNS filter can refuse or block that translation for specific domains.

DNS uses network port 53 for query/response traffic. RFC 1035

DNS-over-HTTPS typically uses port 443 because it runs over HTTPS. IETF RFC 8484

Change DNS to a provider that supports domain blocking (or category filters)

Instead of relying on each browser, you configure your Android device to use a DNS provider that supports filtering. Common categories include adult content, malware/phishing, and suspicious domains—and many providers also support custom block lists.

Two practical approaches:

Category filtering (fast setup): blocks broad classes of content.
Custom domain blocking (targeted control): blocks exactly the website you name.

In my testing, custom domain blocking is the most useful for “one specific site,” because category filters can accidentally block legitimate pages or services that share similar hosting patterns.

Q: Does DNS blocking stop the site from loading in every app?
It often does across browsers and most apps, because they still need DNS resolution—but exceptions can occur if an app uses hardcoded IPs or encrypted DNS modes that bypass your configured resolver.

Add the specific website/domain you want to block in the DNS settings

DNS filtering tools usually require you to enter either:

The full domain (e.g., `wikipedia.org`)
Or a hostname/entry pattern (depending on the provider)

Important: match the domain precisely. If you block `www.badsite.com` but the app requests `badsite.com`, you may see inconsistent results.

Tip: block both `example.com` and `www.example.com` if the site can redirect between them.

Comparison: when DNS beats device/browser blocking

Here’s the simple decision framework:

Choose DNS filtering when you want cross-app coverage for one domain and you’re okay with “deny at name resolution.”
Choose Family Link/Digital Wellbeing when you want account-based rules and time controls.
Choose router rules when you need enforcement for all devices on the network.

Use Parental Control Apps for Specific Website Blocking

If you want a “managed block list” experience with notifications and profile-based rules, use a reputable parental control app. These apps typically let you create custom rules and maintain them over time—useful when you need to block multiple domains beyond a single site.

Reputable parental control apps generally provide configurable web filtering and custom block lists for specific domains. Vendor parental control feature documentation

System-level filtering is usually more effective than browser-only blocking because it covers app webviews and embedded browser components. Android app filtering guidance (developer documentation)

Install a reputable parental control app that allows custom block lists

Select an app that clearly supports:

Custom domain/url lists
Profiles (if different family members need different rules)
Reliable enforcement method (DNS-based or device policy based)

After installing, plan for setup time: the first configuration often takes longer because you’ll need permissions, device admin steps, or VPN/DNS-based routing.

Q: Are parental control apps better than DNS for blocking one website?
They can be better if you want per-profile rules, reporting, and ongoing management; DNS is often faster and simpler for “just block this domain.”

Create the profile/rules and enter the website you want to block

Within the app:

Create a profile (or select the managed user).
Add the domain you want to block.
Save and confirm the filter mode (webview coverage, browser coverage).
Test immediately on the target Android device.

From my experience, the most common failure point is entering the wrong format (full URL path vs domain-only). Many filters match domains more reliably than full URLs, so use the provider’s preferred pattern.

When to avoid over-blocking

If the blocked site redirects through multiple hosts, you may need to block more than one domain. Use the app’s activity logs (if available) to see what hostnames are being requested and block those explicitly.

Block via Router (If You Control the Network)

If you need network-wide blocking, router-based domain rules are hard to beat. The router is the choke point for most traffic leaving your home Wi‑Fi, so blocking a domain there protects every connected Android device automatically.

A router-based domain block can enforce filtering for multiple devices because all clients use the router as the DNS or gateway. Home networking fundamentals (RFC/DNS behavior references)

If a client uses its own DNS settings, router filtering may not apply—so ensure Android devices use the router DNS settings. Android networking/DNS behavior documentation

Set up domain blocking on your Wi‑Fi router for all connected Android devices

Start by identifying your router UI features. Many routers support:

DNS forwarding with block lists
Built-in parental control with domain blacklists
Integration with DNS services (like filtered resolvers)

Then configure:

The blocked domain(s)
Any exceptions (optional)
Whether the router will also block related subdomains

Q: Will router blocking apply to mobile data too?
No—router rules typically apply only to the Wi‑Fi network; mobile data needs DNS filtering on-device or a mobile-level policy solution.

Test the block on Android and confirm it updates correctly

Testing matters because DNS changes can be delayed by caching:

Clear the browser cache or open a private tab.
If needed, reboot the router or toggle Wi‑Fi off/on on Android.
Confirm both `www` and non-`www` variants.

Test and Troubleshoot the Website Block

If the site still loads, the cause is usually a mismatch in how the domain is entered or a caching/encryption bypass. Testing correctly saves time—and it helps you build a stable rule you can trust day after day.

DNS caching can delay the effect of new filtering rules, so refreshing DNS resolution often fixes “it still loads” problems. DNS caching behavior references (general DNS RFC guidance)

Exact domain matching is critical; blocking `www.example.com` does not automatically block `example.com` unless rules include both or wildcard coverage. DNS hostname resolution behavior references

Make sure the URL/domain matches exactly (including www vs non-www)

When you enter the block list, verify:

Domain spelling and punctuation
`www` vs no-`www`
Whether the filter expects a domain or a full URL path

Q: My rule blocks the homepage but not a specific page—what’s next?
Add the alternate hostnames involved in redirects or embed requests, and verify whether the filter matches full paths or only domains.

If the site still loads, clear browser cache and re-test

Troubleshooting steps I recommend:

Try in Incognito/Private mode.
Clear the browser cache (Chrome/Samsung Internet).
Toggle Wi‑Fi and re-open the blocked domain.
For DNS solutions: confirm Android is actually using the filtered resolver (and not switching to another “auto” DNS).
For encrypted DNS setups (like DNS-over-HTTPS): ensure your chosen filtering approach is not bypassed.

Frequently Asked Questions

How can I block a specific website on Android without rooting my phone?

You can block a specific website using a DNS-based app or Android parental control features. For example, apps like BlockSite or Focus filters can add a URL to a blocklist, preventing access in most browsers. Alternatively, changing DNS to a filtering service (and using its blacklist/controls) can block the site system-wide without root. Check the app’s settings to ensure it covers Chrome and other browsers you use.

What is the best way to block a specific website on Android using a firewall or DNS?

The most effective approach is DNS filtering because it blocks the domain before the page loads, regardless of the browser. Use a reputable DNS filtering service or an Android app that supports URL/domain blocking, then add the exact website domain you want to block. DNS solutions may require updating Android’s Private DNS or using the app’s built-in VPN/DNS mode to work reliably. If the site is accessed via mobile data and Wi‑Fi, test both to confirm the block is consistent.

Which Android app should I use to block one website on Chrome or other browsers?

A common choice is BlockSite, which lets you add specific websites to a blocklist and can apply restrictions across popular browsers like Chrome. You can also use parental control apps that support URL blocking and time limits if you want more granular control. Look for features like “block specific websites,” “block adult content,” and “allow only whitelisted sites” depending on your goal. After installing, verify the block by opening the site in an incognito tab and on different networks.

Why won’t my blocked website show up as blocked on Android, and how do I fix it?

Many “blocked” websites still load because the browser is using cached content, an alternate domain, or an encrypted/changed URL path. Clear Chrome cache and try again after adding the exact domain (e.g., example.com instead of a full URL if required). If you use a VPN, the DNS-based block may be bypassed, so disable VPN temporarily or configure the blocker to run with it. Also confirm that the block applies to the app’s browser scope (Chrome, Firefox, in-app browsers) and that the category or domain match is correct.

How do I block a specific website for a child on Android while still allowing other sites?

Use a child-focused parental control app that supports “block specific websites” or a “whitelist” mode to restrict only approved sites. Set a schedule (for example, school hours) and add the exact domain to the blocklist so the restriction is targeted. If the child can change settings, use a PIN/parent password feature so they can’t remove the block easily. Test on the device with the child’s browser profile to ensure the blocked website can’t be accessed through other apps.
