Previously I bought traffic from ad networks and had to make a lot of trouble with precise targeting, rates, and auto-rules. In traffcore everything is much simpler than in smartlink does all the work for me and brings good profits. I initially split them with another broker, but later I realized there is no sense in this action and all the traffic has been transferred to my guys. I also want to mark the possibility of withdrawal to kapu and most importantly without holding. I always get in touch with them and they always give me good advise when it comes to choosing an offer for shedding and I still manage to keep shedding profit).
