I would like to be able to detect if the user is using adblocking software when they visit my website. If they are using it, I want to display a message asking them to turn it off in order to support the project, like this website does.

If you enter to that site and your browser has some kind of adblock software enabled, then the site instead of showing the actual ads shows a little banner telling the users that the ad revenue is used for hosting the project and they should consider turning Adblock off.

I want to do that on my website, I'm using adsense ads on it, How can I do that?

If you have problem with adblock blocking new tab in browser you can do something like this:

$('a').click(function(e){ // change $('a') into more specific selector
    const openedWindow = window.open(this.href, '_blank');

    // Check if browser tab was closed within 0.3 second (user can't, adblock does).
    setTimeout(() => {
        if (openedWindow.closed) {
            alert('Adblock detected!');
        }
    }, 300);

    e.preventDefault(); // return false if you like
});

This code is ONLY useful IF you don't want to block entire site AND just tell users why their browser tabs are closed ;)

Most effective way to detect ad blockers. Step 2 - Leverage the "block list" to reveal the ad blocker. All block lists include a reference to "ads. Step 3 - Check if "ads. js" was loaded or blocked. Example 1 - Send ad blocking data to Google Analytics. Example 2 - Post ad blocking data to an external script. Specifically, with this example you can detect if the default Adblock-list provided by Firefox Adblock is used. It takes advantage that in this blocklist there is an element blocked with the CSS id #bottomAd .

I'm a bit late to the party here but here's the simplest solution I know for the old AdSense code with jQuery:

$ads = $("ins");
if ($ads.length == 0) {
    // Replacement code about you needing ad income
}

And in plain JavaScript:

$ads = document.getElementsByTagName("ins");
if ($ads.length == 0) {
    // Replacement code about you needing ad income
}

For $ads you can use any selector that you know is consistent with the ad being generated. E.g. for the new AdSense code you can use $("iframe#google_ads_frame1").

Go to its website to see the code and example implementation. The bait used by BlockAdBlock looks like this: baitClass: 'pub_300x250  You can run your own scripts to counter the website’s scripts. Note: this site provides free content and we rely on advertisement income to keep this site going.If you are using an adblocker, we plead with you to support us by adding this site to your adblock’s whiltelist.

Run this with adblock on and Paste this in your page-footer before the close of the </body> tag on your page.

<script type="text/javascript"  charset="utf-8">
// Place this code snippet near the footer of your page before the close of the /body tag

For me none of the tricks worked, may be I was doing something wrong. but this is a very specific way to implement for google ads.

window.onload = function() {
   if (document.getElementsByClassName('google-auto-placed').length == 0){
                // Adblock Detected
   }        
}

If you have other ad system like amazon, look for their generic class name / ids by inspecting page.

If you are planing to put this code in seperate .js file make sure file name does not have "Ad" word in it. just name it magic.js

If Google ever decides to change div name, this method would fail. but that seems unlikely.

Now the problem is that most bloggers rely on the ad revenue to support their website. Software like AdBlock plus hurt their revenue potential and  Using Javascript Create a JavaScript file named advert.js or advertisement.js (for this tutorial, am using the former) containing the Use the below script to detect if Adblock is enabled or not. [javascript] <script type=”text/javascript” src=”advert.

I've not seen any good, simple answers that address both of the two types of ad blockers in prevalent use today, so I'll provide my own answer.

Ad blocker type 1: Blocks web advertisement scripts based upon the script name (AdBlock, uBlock origin etc.).

Ad blocker type 2: Blocks web advertisements based upon a database of ad serving host names (FireFox content blocker, various gateway plugins, etc).

This solution works for both. It throws up a big pink "appeal box" asking users to disable their ad blocker. We like to place it below the menus and above the content. We don't actually block access to the site - this just pushes the content down on the page a bit, but people will find it annoying just enough that virtually all will comply and disable their ad blocker on your site.

So here is the solution:

A) Create a file named advertisement.js and place it in the root of your web server, consisting of the following line of code:

document.write('<div id="tester">an advertisement</div>');

B) Inject the following into your web pages (you might even use your ad server code to do this!). Suggested location is below the menus and above the content.

<script src="advertisement.js"></script>
<table id="tbl_ab_appeal" style="width: 900px; margin-left:auto; margin-right: auto; padding: 25px; background: #FCC; border: 1px solid #F66; visibility:collapse; border-collapse: collapse;">
    <tr>
        <td>We've detected that you're using an <strong>ad content blocking</strong> browser plug-in or feature. Ads provide a critical source of revenue to the continued operation of [This website name].&nbsp; We ask that you disable ad blocking while on [This
            website name] in the best interests of our community.</td>
    </tr>
</table>
<script>
    if (document.getElementById("tester") == undefined) adsBlocked();

    function adsBlocked() {
        document.getElementById("tbl_ab_appeal").style.visibility = "visible";
        document.getElementById("tbl_ab_appeal").style.borderCollapse = "separate";
        document.getElementById("tbl_ab_appeal").style.marginTop = "10px"
        document.getElementById("tbl_ab_appeal").style.marginBottom = "10px"
    }
</script>
<script onerror="adsBlocked()" src="//www.googletagservices.com/tag/js/gpt.js"></script>

How does it work? The message is loaded, but made zero height and invisible. If either the local script advertisement.js fails to run, or the remote AdSense script www.googletagservices.com/tag/js/gpt.js fails to load, the box is made visible.

The ad blocker quickly scans the website for scripts. Then these DetectAdBlock simplifies the process of ad blocker detection. Here's how it  How to detect Adblock on my website?
