I guess different people have different responses to the change. Some people gain more revenue while other loose some. It's a trial and error based thing I suppose.
Adsblacklist is just a small amount of websites, you need to get onto each website of yours preview the websites yourself that adsense is showing and make up your own mind on them, and add them 1 by 1 to your filer.
Yes, but for popular niches, you could spend years trying to filter each of them. And you couldn't guess what the Advertiser is paying for them. AdsBlackList does suck though. It's very inaccurate, and my earnings did go down when I tried it, and I only blocked the first 200 of the 800 sites. Apparently, all the interesting looking ads are the ones that dont pay $10 a click.
I would venture a guess that there are very very few advertisers paying $10.00 a click. For example 100 clicks would cost $1,000.00 With a 10% conversion to sale the cost of one sale is $100.00 Now unless there is a high profit margin product or service being offered few online businesses could survive at that rate. Mesothelioma clicks don't pay that much lol.....
That was sarcasm. I meant that the interesting Ads are the low-paying ones, but they make up for the low CPC because more people click on them.
