Ad Blocking Advisor adds a simple and elegant notification bar to your website that only displays to those visitors who are using ad blocking software with their browsers. The purpose of the notification is to ask (or advise) your visitors to whitelist your website. Whitelisting means your ads are displayed, and that’s more revenue to keep you motivated to create more content!
What makes Ad Blocking Advisor different is that it is not limited to just one popular ad provider. In fact, the plugin uses a JavaScript file names ads.js which is popular among ad-blocking software to block! The ads.js inserts a hidden DIV in the footer of your site – you’ll never see it! If the div does not load because it is being blocked then the plugin will display the banner asking (advising) your visitor to whitelist your site!

<li>Easily change the cookie expiration date.</li>
<li>Anti-caching in place with ads.js so that the banner will display more reliably.</li>
