I’ve used Adsterra on a few sites in different niches, and the results were mixed overall. The network is easy to join, and getting ads live doesn’t take much time, which is a plus. I noticed better performance with formats like pop-unders and some display placements, but it wasn’t consistent across all projects.
Earnings seemed to depend a lot on traffic quality, niche, and the countries visitors were coming from. Tier 1 traffic generally performed better for me, while other regions didn’t convert as well. It’s definitely a network worth testing, but I wouldn’t rely on it as the only monetization strategy until you see how it performs with your specific audience.
