Where can I buy traffic?

Here are the main traffic providers:

Ad Networks

Ad Networks are the companies that that serve as bridging points – and as traffic brokers – connecting buyers and sellers alike. Among some of the best adult ad networks out there, there’s TrafficHaus, TrafficJunky, Traffic Force, TrafficFactory, JuicyAds, AdXpansion, ExoClick, PlugRush, EroAdvertising, Traffic Holder, CreamyAds, Etology, and Star-Advertising.

Webmasters

There are still a lot of site owners out there that won’t sell their ad space to networks. They themselves prefer dealing with their site’s traffic monetization operations and you can negotiate ad spots directly from them.

Web Browsers (SEO)
