I have been searching for a good ad networks that gives the best ROI on mobile apps (download, install, leads etc.).
Have gone through some WSOs on this topic where I was advised to use buzzcity, DNTX and zeropark. I did a search on warrior forum and found many negative reviews on buzzcity ad network. Have personally tried DNTX and buzzcity for sometimes with very low success.
Now posting this thread to hear from you experts. Your suggestion would be very helpful to myself and those who are trying to promote mobile CPA offers.
