I want to try BidVertiser and adsense, is it allowed in google adsense TOS. as i know both ad formats are same
As long as the ads don't look the same - use different colours - I don't see a problem personally. Then again, I don't work for AdSense.
The Google TOS is pretty clear... you can use any other ad network ads, even contextual but they must LOOK different. With your ads yes they are different but not sure if its different enough for Google. If in doubt email and ask them.
Hopefully you don't mean to try them out at the same time (adsense and bidvertiser ad blocks on the same page at the same time)
Off-Topic :: bidvertiser isnt any good as they dont count clicks appropriately . But then again , theres no harm in trying
They have recently changed their policy regarding placing other PPC ads.. you can place other PPC ads along with adsense ads, but format should be different.. ( but YPN + google still not allowed I suppose )
Worth a shot if you want more than the 3 adsense units... ad in bidvertiser lol. I think it'll make the site unappealing when filled with ads though.. so might give a negative effect
Ofcourse , it will give a negative effect if you are having loads of ad units or even more ads then the content itself . I had bad experience with them .. I just gave them a trial months back and with same amount of traffic and everything .. I had less number of clicks reported in my account < when compared with adsense > and bidevrtiser dont pay well .. low costs for clicks . Also , I read somewhere in the forum about bad experience of people with bidvertiser .
i will try bivertiser for a month, and then decide, and before using them i will just send them a screen shot, and ask them if it's right
