It's not for anyone specific, but there has been a recent trend on DP for people offering to buy signature space and avatars for advertising their own sites. I have over sixty sites, but have chosen not to use the space for any advertising - just an individual decision.
I am sure there is someone got $60 by only a single click. maybe is about law or medicine. dont really remember
my understanding to this is: the advertisers offer such high price for that keywords such as "". and they pay for publishers to publish theirs ads and the more publishers participate to that kind of that ads the less revenus the publishers would get. am i make sense? (I am not sure either)
No, you are not making any sense. It is a complicated process, but it begins with advertisers bidding on a keyword. The bidding is like ebay and starts at .01 cent. The more the advertisers bidding, the higher the pricing goes. The highest bidder is not always in the #1 spot - the CTR is factored in. As a publisher, the pay you receive can be lowered (smart pricing) if your site is not converting for the advertiser. This determination is made by google. Google pays out approximately 77% of what they charge the advertiser and keep 23% for themselves. The 77% comes from their SEC filings and is an average - certain premium partners may or may not get a higher percentage. All google discloses is that all regular adsense publishers get the same percentage - and when you combine premium publishers with regular publishers, they pay out 77%.
I have a medical niche site. I've had clicks that paid $0.03 and yesterday I had a click that paid $3.58. Very inconsistent so don't count on always getting high price clicks.
I tried it. No change in CPC. The logic behind it is BS. But I filter those crappy MFA sites anyway because, well, they are crappy. They aren't interesting so visitors won't click once they learn to recognize them. And I don't want to support them, want to see them die so they stop cluttering up the internet with their garbage.
