AdXpansion is a platform to buy and sell adult traffic. I do have an account there and have had a positive experience using their platform.
They have a very simple and intuitive dashboard and back office and have very affordable traffic.
I’m not sure how large their network is, but the cool thing about adult traffic in general is that: it’s real people, it’s usually quite cheap, and there’s typically a ton of it.
Most other marketers never consider adult traffic I guess because they think it’s dirty and they only respond to and buy certain things. However, that’s not true. There are tons of other offers you can put in front of them, you’ll just have to test.
Or if you’re just looking for a very cheap place to get lots and lots of country-specific human traffic, without having to pay one of the more premium channels like Google or Facebook, you should definitely consider adult media. Learn more about AdXpansion.
