In my case, it turned out that inpage and native are the most effective formats. I ran it on tier3 with push subscriptions. Price per click starts at $0.001 for more than 2,000,000 impressions and 100,000 clicks. You can only dream about such high ROI, but with evadav it is a reality. I really like the ability to set up black and white lists, and auto-rules save and do not let drain the budget. The manager is always in touch 24/7, so even if some problems arise, they are easy to solve.
