I haven't used Bidvertiser for a few years and I just got this email from them a few hours ago: Dear Jim, We are happy to announce that starting September 1st 2011, BidVertiser will be supporting Slider Ads. Slider Ads are ads that are sliding up from the bottom of the screen and show on top of the page. This ad format is incredibly popular and it generates extremely high revenues. Slider Ads are showing up only once per 24 hours per user, are completely non-intrusive and have a small close button right above them. The great news are that we have been testing Slider Ads with our top publishers for the past months and results are fantastic, generating a revenue growth of over 200%. The revenue payment for the Slider Ads will be listed as part of your Conversion Revenue. As always, quality of traffic makes a difference in this case as well and publishers with high quality traffic will enjoy extended Conversion Revenue payments. Will any of you be jumping on this?
