Pop traffic has been around for a while, but new platforms still pop up now and then. One rising name is TrafficStars, which many users say gives decent volume and more control over campaigns. Some people have also mentioned RollerAds as a good source for mobile pop traffic. Testing smaller or newer networks can sometimes bring better prices since competition may be lower. Still, it’s important to monitor traffic closely and make sure the traffic is converting. If anyone knows other newer sources that deliver good ROI, it would be helpful to hear about them.
