I own a PTP, And i can provide 2 million unique iframe hits in a day for just $20. The traffic comes from various traffic exchanges etc.. from my users. And can be used on many ad networks.
Live traffic from my google analyltics :
Yesterday's Geo's :
As you can see 50%+ from USA.
No redirects/framebreakers.
To track the number of hits we can use goo.gl or any other url shortener.
Thank you.
