Regarding
Bidvertiser, I'll copy the answer I gave to one of my commenters:
You can display Bidvertiser and Adsense on the same page, as long as you choose different color schemes for Bidvertiser ads. Take a look at
Google’s answer:
“You’re welcome to display Google ads on the same site or page as other third party advertisements provided that the formatting or colors of the third party ads is different enough from that of the Google ads. In other words, if you choose to place non-Google ads on the same site or page as Google ads, it should always be clear to the user that the ads are served by different advertising networks and that the non-Google ads have no association with Google. If the formats are naturally similar, we ask that you choose different color schemes for the competing ads.”
Regarding Bidvertiser, they don’t mention anything about displaying their ads along with other ads on the same page.
