Detect Missing Adblocker

Warn your website's visitors if they don't have an adblocker enabled.

MythThrazz

<p>Over 40% of internet users run an ad blocker. <strong>Tiny Simple AdBlock Detector</strong> gives you the power to respond — politely ask visitors to whitelist your site, gate premium content, or simply track awareness — all without touching a line of JavaScript yourself.</p>
<h3>How it works</h3>
<p>The plugin loads a tiny decoy script with a filename that ad blockers love to block. When the script gets blocked, a lightweight CSS class swap kicks in — revealing or hiding any element you’ve marked up. That’s it. No jQuery, no external services, no tracking pixels, no cookie banners.</p>
<h3>Two CSS classes. Infinite possibilities.</h3>
<ul>
<li><code>class="show-only-when-adblock"</code> — Element appears <strong>only</strong> when an ad blocker is active.</li>
<li><code>class="hide-only-when-adblock"</code> — Element disappears when an ad blocker is active.</li>
</ul>
<p>Add them to any HTML element: a <code><div></code>, a Gutenberg block, an Elementor section, a WooCommerce notice — anything.</p>
<h3>Real-world examples</h3>
<ul>
<li><strong>“Please whitelist us”</strong> — Show a polite banner only to ad-blocking visitors</li>
<li><strong>Content gating</strong> — Hide exclusive articles or downloads from users blocking your ads</li>
<li><strong>Alternative monetization</strong> — Show a “Support us on Patreon” box only when ads are blocked</li>
<li><strong>Analytics</strong> — Pair with your analytics tool to track ad-blocker adoption rates on your site</li>
</ul>
<h3>Why this plugin?</h3>
<ul>
<li><strong>Zero configuration</strong> — Activate it and it works. No settings page, no wizard, no API key.</li>
<li><strong>Ridiculously lightweight</strong> — Under 2 KB of JavaScript. Your visitors won’t notice.</li>
<li><strong>No external requests</strong> — Nothing leaves your server. Fully GDPR-friendly.</li>
<li><strong>Works with all major ad blockers</strong> — uBlock Origin, AdBlock Plus, AdBlock, AdGuard, Brave Shield, Opera built-in blocker.</li>
<li><strong>Page builder compatible</strong> — Works with Gutenberg, Elementor, Divi, WPBakery, Beaver Builder — anything that lets you add a CSS class.</li>
<li><strong>Built-in debug mode</strong> — Append <code>?tsad_debug=1</code> to any URL to see live detection results.</li>
<li><strong>Translation-ready</strong> — Includes Polish translation. PRs welcome for others.</li>
</ul>
