Result: During the first eleven months the revenue was quite good. 5% – 40% per month of what Google AdSense generated. But since December 2012 the revenue went down to exactly 0%!
Notes: We contacted Zanox about the total drop in revenue in their contact form. But we didn’t get an answer!
Update: When we asked them on their Facebook page if they read the questions from their contact form, the question just got deleted after about a day.
Update 2: Our last try was to e-mail them about this. The e-mail address was well hidden on their site, but we got an answer after about half a day. It turns out that the Zanox Ad Server has been cancelled and is replaced by Zanox Ad Delivery. Looks like we have to come back with a new test of that. But it is really bad that they cancel a service without informing about it!
