Nowadays, many visitors use ad blockers (adblock, adblock plus, etc.) to remove ads from websites. The ever-increasing use of such software can significantly affect the revenue generated by a website.
Our web analytics service provides detailed statistics on the use of these ad blockers, so that you can evaluate their impact on the monetization of your website.
Using two different algorithms, AFS Analytics detects ad blockers on all devices: Computers, Tablets and smartphones.
The best way to combat ad blockers is to display a warning message or banner asking the user to disable it. For this reason, the analytics.js library allows you to define a (callback) function in JavaScript which will be called every time an ad blocker is detected. You will find an example of use at the end of this document.
From the main menu, select advanced mode, then the Adblock Detection option:
This graph shows you the percentage of visitors using ad blocking software.
This list displays visitors using ad blockers.
