Looking for a list of sites to block from advertising on my Adsense account. I'll start with one: brokerstocksonline.com The page is parked through parked.com, I contacted Adwords support and they're fine with this kind of site advertising. I'm not fine with advertising a parked page on my site, though. Any others?
simple business rules: 1. filters the more adwords users you block = the more competition you block = the more bidders you kill = the less competition for adsense slots on your site = the cheaper your clicks i have zero filter and 2 digits average all over ( all over= eCPM / CTR ) 2. the more unique content + the higher your traffic + the higher the quality of unique content = the more likely you attract site advertisers of HIGH quality 3. result of 1+2 above the more high quality site advertisers OR targetable channel advertisers you attract = the more this strong generic high end advertisers will PUSH out all cheap low end advertisers from the ad slots offered on your site. the only thing I "worry" and care of to create more and better content - and the result is a nice 2 digit eCPM/CTR on a high traffic site. all low end adword users have dropped OUT of the competition!
Sometimes filtering out MFAs can increase your earnings. After I added a list of mfas my earnings increased.
Many people filter MFA sites and report increased earnings. Maybe it's because if your site is low quality and therefore shows only low paying ads, if you filter those low paying ads maybe AdSense has no choice than to show a little more expensive ads to fill the ad space. I just thought of that, I didn't make any tests so I can't say this is true, just a theory.
