In late December, we reported that Google's AdSense Competitive Ad Filter stopped working for many publishers. Guess what, it is still not working for many of them and they are feeling very let down by Google. If you don't know what Google's competitive filter is, it basically gives publishers the functionality to block specific ads from appearing on their pages.
Successful AdSense publishers depend on the competitive filter to block out the MFAs and poor quality sites from displaying on their sites. But since late December, the filter stopped working for many. Here are some of the continued complaints in the WebmasterWorld thread:
I've managed to keep earnings up by constantly monitoring and blocking ads but my filter is filling up with garbage. Once it's full and my site visitors see nothing but crap ads and stop clicking, that's it, buh bye AdSense.
I'm with coach. This is pretty sad.
I let it go a few weeks to see what would happen- Sounded like ASA was all over it. I guess not. I tried blocking a few more today and they were already in the ad filter. Nothing can be done I guess.
I am surprised the ASA has become quiet over this. It is not as if he/she isn't aware of the problem.
