Are Ad-Blockers Killing Your Website’s Income?
It is December 2026. You spend hours creating high-quality content, optimizing your SEO, and driving traffic to your site. But when you look at your analytics, the revenue doesn't match the view count.
The culprit? Ad-Blockers.
Recent statistics show that over 40% of internet users now browse with an active ad-blocker. If your website relies on Google AdSense, Ezoic, or Mediavine, you are effectively working for free for nearly half of your audience.
Why Most "Anti-AdBlock" Plugins Fail
If you have tried using WordPress plugins or simple scripts to detect ad-blockers, you probably noticed they don't work anymore.
Modern extensions like uBlock Origin and AdGuard are smart. They don't just block images; they block the scripts that check for blockers. They hide static HTML elements with names like ads-banner before your page even loads.
The Solution? Dynamic Injection.
Today, I’m sharing a custom-coded, lightweight script that uses JavaScript Dynamic Injection. Instead of placing a static trap in your HTML, this script creates a fake ad in real-time. The browser thinks it's a real ad, the ad-blocker kills it, and our script detects that "murder" instantly—locking the screen until the user disables their blocker.
The Code: Copy & Paste Solution
Below is the complete, all-in-one solution. It includes the CSS for a professional, "Dark Mode" friendly modal and the advanced JavaScript logic to bypass detection filters.
How to use it:
Go to your website's Thinking or Footer.
Paste this code right before the closing </body> tag.
Save and watch your revenue recover.

(function() {
function detectAdBlock() {
var modal = document.getElementById('adblock-gate-overlay');
var bait = document.createElement('div');
bait.className = 'pub_300x250 pub_300x250m pub_728x90 text-ad textAd text_ad text_ads text-ads text-ad-links ad-text adSense adBlock adBox';
bait.style.setProperty('width', '1px', 'important');

var computedStyle = window.getComputedStyle(bait);
if (bait.offsetHeight === 0 || bait.offsetWidth === 0) isBlocked = true;

How This Script Works (Technical Breakdown)
For my fellow developers, here is why this script succeeds where others fail:
Multiple Trigger Classes: We assign classes like pub_300x250 and adSense. These are universal triggers in the "EasyList" database used by 99% of ad blockers.
Computed Style Check: We don't just check if the element exists. We use window.getComputedStyle() to see if the extension injected CSS (like display: none !important) to hide our bait.
Double-Tap Detection: We run the check twice—once on page load, and again after 2 seconds. This catches "lazy" extensions that wait for the DOM to settle before blocking ads.
Is This Safe for SEO?
Yes. Google bots do not use ad-blockers, so they will never see the popup. Your content remains fully crawlable and indexable. This method simply ensures that human visitors exchanging their attention for your content are actually supporting you.
Conclusion
Website monetization is getting harder in 2026. You shouldn't have to choose between user experience and paying your server bills. This script offers a polite but firm way to ask users to support your work.
