I’ve noticed that my adsense revenue has dropped a lot this last few months. I guess my site is not targetted to the right words and most of the ads are paying pennies due to MFA sites (made for adsense). So its not Google Inc’s fault.

According to Search Engine weblog , the way to spot MFA sites is :
” if you see more ads than content, then that’s a very likely candidate. Another is if you see scraped content.”

So head on over to that article to learn how to get rid of this dumb penny ads.

The Competitive Ad Filter enables you to block specific ads, such as competitors’ ads, from appearing on your pages.In the field provided, list URLs of sites whose ads you want to filter from your pages. Then click Save changes. Changes will take effect within a few hours.

To jumpstart your competitive filter contents, try visiting adsblacklist.com and you can see a lot of those MFA sites. They maintain a list of known MFA websites. Just cut and paste it to your competitive ad filter in your adsense account.

Increase your Adsense CTR - remove MFA sites source

Update: 10 Aug 2006
I’ve added some MFA domains from the list at adsblacklist.com and my revenue has doubled overnight ! It really works and now I see less of those dumb stupid ads on my site ! Here’s 2 lists I’m using right now..
