netbot, for some reasons, after inputing those sites. my revenue drops to almost half. so in other words, it doesn't always work for everyone. BUT> it's worth trying for your self
The only way it could work is if google's adsense system was malfunctioning. What happens is that when you filter an ad because of low pay it will be replaced with an ad with even lower pay, not by a magically apperaring high paying ad. It just doesn't work. However, I could see a use for filtering certain low converting ads, to avoid smart pricing. However, determining exactly what ads converts less would be hard I think. A good guess though would be MFA sites, but it's hard to tell.
It doesn't work for everyone I mean for all niche sites. And please wait for a week and then analyze how is your income. Since it will take 24 to 48 hours for Google to update the new ads for your site.
I dont use the adblacklis thing. I just look for cheap looking urls from my adsense ads n filter them out. For example, urls like8-topsites.com, 10-topwebsites.com...u can instantly recognise that these r MFA's, so just filter em out....
