Adblocking software has an impact on us all – as affiliates, merchants & consumers.
Seems that there are multiple factors that contribute to ads being blocked by ad blocking software including using IAB standard ad sizes, using certain combinations of HTML code that triggers the ad stripping and ad blocking isn’t limited to graphical ad formats either –text ads can be blocked as well and it’s been has been known to block text links as well including adsense and adwords ads.
One key thing to do would be to educate your visitors and put a message on your site to let them know about ad blocking and how to turn it off. This way they will know that it not a problem with your site and that is a problem with Norton who made the decision for them to block ads.
By no means am I an expert on this subject although I had been trying to keep up with the workarounds.
