Hello,
I am glad a developer behind RTB is here.
RTB faciliates tracking and profiling. It makes it easier.
Also, sites are being sent in the bid requests... Price for an ad on site X.com is different than on Y.com. How else do you explain the price difference?
Do you seriously want us to believe that you don't know the site you're displaying ads on?
Also, where is the list of bidders which receive bids with my data, when I visit a site? Why is the technology so untransparent?
Prices for users in USA are higher than in some other places, retargeted ads receive higher prices...
Please be more elaborate than just spotting wordings in abstracts and text.
