Android does not have one universal setting for blocking any website you type into a list. The right method depends on who the phone belongs to and how widely the block needs to apply.
For a child’s supervised Android phone, Google Family Link is the most direct option. For your own phone, a website blocker or filtering DNS is usually more appropriate. Router controls work well at home but stop protecting the phone when it leaves that Wi-Fi network.
Start with the outcome you actually want:
| Goal | Best starting point |
|---|---|
| Block one or more sites for a child | Google Family Link |
| Allow a child to use only approved sites | Google Family Link |
| Block distracting sites on your own phone | Reputable website-blocking app |
| Filter adult, phishing, or malicious domains more broadly | Filtering Private DNS |
| Apply restrictions to every device on home Wi-Fi | Router parental controls |
| Stop annoying pop-ups or notifications without blocking the site | Chrome site permissions |
The distinction matters because blocking a website, filtering search results, stopping notifications, and blocking pop-ups are four different things.
Can Chrome on Android Block Any Website You Choose?
Not on an ordinary adult Chrome profile through a simple built-in blocklist.
Chrome for Android includes controls for pop-ups, notifications, permissions, Safe Browsing, and other security features, but those do not create a permanent custom list of websites you cannot visit.
Google does provide specific website blocking in Chrome for supervised accounts through Family Link.
Also avoid desktop tutorials that tell you to install a Chrome extension. Standard Chrome for Android does not use the full desktop Chrome extension system.
If your goal is parental control, use Family Link. If you are blocking sites for yourself, skip to the website-blocker or DNS sections.
Block Specific Websites With Google Family Link
Family Link is designed for parents and guardians managing a child’s supervised Google Account.
Google currently allows a parent to choose among three broad Chrome and web settings:
- Allow all sites
- Try to block explicit sites
- Only allow approved sites
You can also manually add approved and blocked sites.
On the parent’s phone:
- Open Family Link.
- Select the child.
- Tap Controls.
- Open Google Chrome and Web.
- Under Manage sites, open Approved sites and Blocked sites.
- Choose Blocked sites.
- Tap Add a website.
- Enter the site or domain.
- Save it.
Google says these restrictions apply in Chrome and some Android apps for the supervised account.
Website vs domain matters
Family Link distinguishes a specific website address from a broader domain rule.
For example, blocking one exact host may not automatically cover every regional version or separate domain used by a service.
When you need broader coverage, use the domain option Family Link provides rather than adding one long page URL.
After saving the restriction, test the site on the child’s phone.
Allow Only Approved Sites
For a younger child or a tightly controlled device, blocking sites one at a time can become endless.
An allowlist reverses the process: only sites you approve are available.
Open:
Family Link > Child > Controls > Google Chrome and Web
Choose Only allow approved sites, then add the websites the child needs.
This can make more sense for a device used mainly for school, educational services, or a small number of family-approved websites.
A child can request access when a site is blocked. The parent can review and approve or deny that request.
Google also disables Chrome Incognito mode when a child is signed in with a Family Link-managed account, which makes Chrome restrictions more meaningful than a normal adult-browser blocklist.
A Website Is Blocked in Chrome but Still Opens in an App
This is a coverage problem, not necessarily a failed block.
A service can be accessible through:
- its Android app;
- an in-app browser;
- another installed browser;
- a different domain;
- links opened inside social media or messaging apps.
For stronger parental controls, review which apps the child can use in Family Link as well as the website restrictions.
Blocking example.com does not automatically mean the Android app for the same service can no longer connect.
This is why parental control should be built around the child’s account and allowed apps rather than one browser rule alone.
Block Websites on Your Own Android Phone
Family Link is not intended to be a self-control tool for an ordinary adult Google Account.
When you want to block distracting websites on your own phone, a dedicated blocker is usually the simplest approach.
A blocker may offer:
- custom domain lists;
- work or study schedules;
- focus sessions;
- app blocking;
- keyword rules;
- PIN protection;
- temporary lock periods.
Before installing one, check its current Google Play listing carefully.
Website blockers may require powerful access such as Accessibility permission or a local VPN. Those permissions can potentially reveal information about what appears on your screen or which domains the phone requests.
Prefer an established developer with a clear privacy policy, recent updates, understandable permissions, and a Google Play Data safety disclosure you are comfortable with.
Avoid downloading an unknown blocker APK merely because it promises stronger restrictions.
Understand Accessibility-Based Website Blockers
Some blockers use Android Accessibility services to recognize a browser or website and place a blocking screen over it.
That approach can support precise domain blocking and schedules across multiple browsers, but it has weaknesses:
- the Accessibility permission can be revoked;
- battery restrictions can interfere with the blocker;
- some in-app browsers may behave differently;
- the user may be able to uninstall the blocker;
- the app receives broad accessibility privileges.
Use this method when custom self-blocking is more important than network-wide filtering.
Do not grant Accessibility access casually to an unknown application.
Understand Local-VPN Website Blockers
Another design is a local VPN.
The blocker creates an Android VPN profile and uses it to control network requests from the device.
This can cover more than one browser, but Android generally allows only one active VPN connection at a time. A blocking VPN can therefore conflict with a normal work, privacy, or commercial VPN.
A local-VPN blocker can also be disabled by the phone’s user unless stronger device-management controls are in place.
Read the developer’s explanation of how traffic and browsing information are handled before granting VPN access.
Use Private DNS for Broader Filtering
Private DNS is useful when you want broader domain filtering across the Android device rather than a block page inside one browser.
Android’s Private DNS setting accepts a DNS provider hostname. It does not accept the website you want to block.
A filtering DNS provider can classify and refuse domains associated with categories such as:
- adult content;
- malware;
- phishing;
- tracking;
- gambling;
- social media.
The exact categories depend on the provider.
On Pixel and many Android phones, open:
Settings > Network & internet > Private DNS
Choose Private DNS provider hostname, enter the hostname supplied by your chosen filtering service, and save it.
On Samsung Galaxy phones, the usual path is:
Settings > Connections > More connection settings > Private DNS
Other manufacturers may place it elsewhere. Search Settings for Private DNS when necessary.
Private DNS is not a custom website box
Do not enter:
facebook.com
or another site you want to block into Android’s Private DNS field.
That field expects the filtering DNS service’s hostname.
If you need a personal denylist, choose a DNS provider that supports custom rules through its own account/dashboard. Configure the block there and then use the provider hostname it supplies for Android.
Why a DNS Block Can Be Bypassed
DNS filtering is broader than a browser extension, but it is not absolute.
A block can fail when:
- a browser uses another secure DNS resolver;
- a VPN sends DNS elsewhere;
- an app uses its own network behavior;
- the domain classification is incomplete;
- the service uses multiple domains;
- cached DNS data has not refreshed.
After changing DNS, close the browser, reconnect the network or restart the phone, and test on both Wi-Fi and mobile data.
When the phone suddenly has no internet after changing DNS, recheck the provider hostname. A mistyped or unavailable Private DNS provider can prevent domain resolution.
For broader Android connectivity problems, Wi-Fi Connected but No Internet on Android? How to Fix It can help distinguish a DNS problem from a general Wi-Fi failure.
Block Websites Through Your Wi-Fi Router
Router-level filtering is useful when the restriction should apply to several devices at home.
Sign in to your router’s administration interface and look for a feature named something like:
- Parental Controls
- Website Filter
- URL Filter
- Access Control
- Content Filtering
The exact controls depend entirely on the router or internet provider.
Assign the rule to the Android phone or to the appropriate family/device profile, then test the blocked site.
The important limitation
Router rules normally apply only while the phone uses that router.
The same website can become available when the Android phone switches to:
- mobile data;
- another Wi-Fi network;
- a hotspot;
- a VPN that bypasses the router’s filtering design.
For a child’s phone that travels outside the home, device/account-level controls such as Family Link are more appropriate than relying solely on the router.
Do You Actually Need to Block the Website?
Sometimes the website itself is not the problem.
Stop website notifications
When a site keeps sending alerts, open Chrome and go to:
More > Settings > Site settings > Notifications
You can turn site notifications off or change the permission for a particular site.
Google also lets you open a site’s page information and change its notification permission directly.
This stops the alerts without preventing you from visiting the site.
Stop pop-ups and redirects
Open:
Chrome > More > Settings > Permissions/Site settings > Pop-ups and redirects
Keep pop-ups and redirects blocked.
Chrome already blocks many pop-ups by default.
This is useful when the complaint is “this site keeps opening ads” rather than “I never want this site accessible.”
Filter explicit Google Search results
SafeSearch can filter or blur explicit content in Google Search results, but it is not a website blocker.
A person can still reach a site through another search engine, a direct URL, another app, or a link.
Use Family Link website restrictions or another filtering layer when actual access must be restricted.
Why a Blocked Site Still Opens
Instead of immediately installing another blocker, identify the path that still works.
It opens in another browser: the original method probably controls only one browser.
It opens inside an app: block or manage the app separately.
It opens on mobile data but not Wi-Fi: the restriction is probably on the router.
It opens with a VPN enabled: the VPN may be bypassing the DNS or network filter.
One subdomain still opens: the rule may cover only a specific host rather than the whole domain.
The block works until the phone restarts: check whether the blocking app still has the permission or VPN state it requires.
The failed path tells you which layer needs changing.
Which Method Gives the Strongest Control?
For a supervised child’s Android device, start with Family Link because it ties restrictions to the supervised Google Account and can combine Chrome/web controls with app management. Google notes that its explicit-site filter is not perfect, so manual blocked sites or an approved-sites-only configuration may still be appropriate.
For an adult blocking distractions, a reputable dedicated blocker provides more useful scheduling and custom-domain controls than trying to force parental supervision onto your own account.
For broad category filtering across several apps, Private DNS is cleaner, provided you understand that DNS filtering can be bypassed by some VPN or secure-DNS configurations.
For a whole household, router filtering adds another useful layer, but it should not be mistaken for protection that follows an Android phone everywhere.
The best method is therefore determined by where the restriction must follow the phone. A Chrome rule controls supported browsing, a blocker follows the device, DNS filters network lookups, and a router controls only the network it manages.
