Ad Blocker Detection

Ad blockers, like AdBlock or AdBlockPlus, works with a block list of URLs and patterns. By knowing how they work, you can implement a check to determine ad block status and handle users who block advertising on your site accordingly. To detect ad blocking, you can use this code on your page:
<script src="//" type="text/javascript"></script>
<script type="text/javascript">
  window.addEventListener('load', function () {
    if (document.getElementById('My-AdServer')) { 
      alert('Good! Ads NOT Blocked'); 
    } else { 
      alert('Bad! Ads BLOCKED'); 
      // do something since this viewer is not seeing ads on your site
      // eg: if you want to redirect to your advertising/ad-supported notice page
      // window.location = "";
You should change the default behavior, which opens a message dialog, to a suitable action. You can show a message, redirect to a notice/entrant page or log the response to find out how big of an impact from ad blockers on your site and advertising revenue.
