As a publisher, you may want to measure what percentage of your visitors are using an Adblock, so you can take action accordingly.
For example, you can show an "Adblock Detected" warning message and ask them to disable their ad blocker in order to continue.
Or you can deny access to your web pages completely using a paywall.
To do so, you need an Adblock Detection Script.
AdGlare Ad Server is using the script here below, which is available for you to use free of charge.
It works by creating a DIV that is likely to be hidden by ad blockers, and then verifying if that DIV was indeed hidden.
The presence of an ad blocker has been successfully detected in these web browsers at the time of writing (June 2018): Chrome, Firefox, Safari and Internet Explorer 8+.
As a publisher, you should at least measure Adblock usage on your website. If only a small portion of your traffic
cannot be monetized due to ad blockers, you can consider denying access to those visitors.
If usage is high, alternative ad serving methods that circumvent ad blockers are worth considering, like
Native Ads. Publishers monetizing video content can switch to Server-Side Ad Insertion to get around ad blockers.
