I only tried the push of this traffic network, in fact they have many formats, but push is not the ad format they are good at. Because there is very little traffic, only the United States, the United Kingdom, and Canada have more push traffic. And I feel bad about the quality. I spent $ 50 to test, and there was no conversion. And even if I advertise in the US, my bid is an average bid, and I can only get 70,000 impressions per day, which is too few.
Bidvertiser has high quality traffic but the volume is not good enough specially for Tier2 and 3 , also the bid is too high comparing with most famous like popads and popunder, but they give you $50 bonus to test the platform, and if you y to cancel it anytime before start to spend the min fund which is $100, you can cancel any time if you decide to refund $100 (actually $100 not spent but just pending untill you decide) thats means that there is no risk to test this platform. To be honest I didn't get a decision to recommend it or not , but so far so good, also the skype support are fast which give them more advantage.
I just started to use BidVertiser, but so far, I think they need a few more macros to optimize. I find that everytime I create a campaign, I need to send them a screenshot of the URL because apparently it doesn't load correctly. Also, their User Guide could use an update.
