I have few similar questions. 1.If I have a site containing adsense ads, can I promote them in ptc sites. ptc(paid to click) site is a site where you have to buy impression from it. and members will visit your site for and they will get paid for their visit. I know traffic exchange site are not allowed but what about ptc's? 2.what about adword? Can I buy impression for the site that contains adsense? 3.what if I buy impressions from adbrite/ bidvertiser/yahoo publisher or from any other publisher sites? Thanks in advance...
