Hello everyone. Recently I have been on iWebTool.com using all of there great webmaster tools and I found AdsFlip, a ad service by them. Very simply... you put some code on your site which shows ads and for every impression on that ad you get a credit. Then credits can be spent to put your ad on other peoples sites. No money involved. Looking more into it, I was wondering if using this service could boost my PR. I mean, its an ad so it should at least get me a little more traffic. But will these links (though they are ever-changing, kind of like Adsense ads) get me "points" on the scale of PageRank? And also, if anybody is using this service I'd be curious to know what you think about it. Thanks.
