You can find many lists of such "adsense revenue sharing sites" by searching on google with the 4 words I wrote for you. Also, I have two adsense revenue sharing sites, one is shetoldme it's a digg like and the other is best-reviewer it's a site where you submit top lists, can be lists of anything as long as it doesn't violate adsense TOS.
I don't understand why people look for adsense revenue sharing sites. If you create your own sites or blogs you will not only earn revenue from adsense but also you will be able to sell such sites and bank big monies. On the other hand if you post on adsense revenue sharing sites the site owner will take major share of booty and you will only get a few cents per day if you get lucky.
Yes it's true, but people using those sites can also have backlinks benefits from the site's higher PR and traffic + a chance to get extra adsense money, that's better than posting on article directories, digg-like or blog commenting without adsense revenue sharing. So that's understandable, although it's true that when you know how to make websites and have built several you don't need to use other people websites to make backlinks, me I don't use any other sites than mine to do this, or if I want links I buy them or make link exchange.
You should try youself rather helping from other sites.your content should be unique and seems to b impressive to the readers you will get traffic automatically
You should use other method for back links as well. If you do post ads on your website then it would be very advantageous.
