We've been working with Zeropark for over 7 years already and it has always been a very reliable traffic source. The traffic has good quality, the UI is intuitive, the targeting options are just right for our need, the volumes of available traffic worldwide is quite high and the optimization tools are helpful and trustworthy. Not to mention the account manager, who is always there to help us increase the performance of our campaigns, giving us useful tips, assisting us in any campaign related issue we might have and being friendly.

It would be great if we could make more in-depth targeting inside the campaigns, such as version of browser or version of OS.

Zeropark has good quality traffic, which converts, good volumes in any geo and good optimization tools. You can simply open campaigns there, set up the rules and let the algo do the job for you.
