There are a few reasons for this:
- There is a one-day delay in all the income received from the ad networks due to different time zones.
- The traffic is not unique: usually ad networks register unique traffic only.
- Ad networks such as TrafficShop or PopAds register traffic from verified domains only. If you send traffic from different domains to Popcash, you need to make a request for special popunder links for Popcash support.
- The stats are affected by ad blockers.
