I set up a service a few weeks ago (PageRank Search) availalbe for free to visitors. I am sharing revenue (50/50) - simply link to the engine from your DP signature or website. You must create a new channel so you can track visits and earnings. The tool is very popular and most users visit several times a day. You can find the service at: http://www.essaybuzz.com/prsearch.php Link as follows to the page in order to start earning from visitors you send (your Adsense ID is added to their computers so for every new visit you will still receive 50% of revenues). http://www.essaybuzz.com/prsearch.php?gid=pub-3529485735637294&ch=5814706055 Simply replace the 'gid' and 'ch' with your Adsense ID and the channel you create, respectively.
Will get your account banned? In the signature if 5-6 people post then thats more then allowed advertisements per page. Google will check into this and see all of the accounts on one page and they may be problems. I might be wrong but just putting this out there for discussion.
Not at all - it's no different than DP revenue sharing. Except that beneficiaries earn because they promote instead of contribute content like at DP. I am only in a startup phase any comments or ideas are welcome.
