Hi, We are trying something new and we have in mind to create brand new websites that we will be used to do arbitrage but this time without Adsense, we will rather be using others adSevers through Headerbidding. My question might be silly, but I'm not that savvy when it comes to programmatic. Is there any good DSPs that have good CPM's that accept new websites with little to no traffic? We will be sending a shitload of traffic to those sites after being accepted but they don't know that. Any suggestions?
