Learn how to detect ad blockers in mobile browsers and ensure your ads display correctly
Why Ad Blockers Matter on Android
Ad blockers are increasingly common on Android devices. They can prevent your ads from displaying, impacting your revenue and user experience. Detecting ad blockers allows you to:
Identify Blocked Ads
Determine when your ads are being blocked by browser extensions or content filters.
Communicate with Users
Politely ask users to disable ad blockers to support your content.
Track Analytics
Monitor how many users are blocking ads to understand your revenue impact.

Ad blocker detection works across all major Android browsers:
Detection Techniques
Here's a reliable JavaScript method to detect ad blockers on Android:
function detectAdBlocker() {
// Create a bait element that ad blockers would typically block
const bait = document.createElement('div');
bait.className = 'ad ads adsbox doubleclick ad-placement ad-placeholder ad-banner';
bait.style.height = '1px';
bait.style.position = 'absolute';
bait.style.left = '-1000px';
bait.style.top = '-1000px';
document.body.appendChild(bait);
// Check if the element was modified or hidden
const isBlocked = bait.offsetHeight === 0 ||
bait.offsetWidth === 0 ||
bait.style.display === 'none';
// Clean up
document.body.removeChild(bait);
return isBlocked;
}
Note: This method creates a hidden element that mimics ad containers. Ad blockers typically hide or remove such elements. By checking the element's dimensions and visibility, we can detect if an ad blocker is active.
