ok, i ran an experiment and wanted to get some of your opinions in the matter.
i have geo targetted a page to show US only traffic. i have my trackers in place to track everything. i also only let a small portion of traffic into the page to keep a smaller control.
1 page - 4 US clicks from 4 different IP addresses which resolve in 4 different US states clicking 4 different advertisers.
Results - YPN report shows that only 2 clicks were valid, throwing out 50 % of my valid clicks for that channel. I have been seeing these results on all of my pages, but this was a controlled experiement. Also, I checked these 4 ip addresses to see if they by chance had clicked on any other ads in my network of sites, giving a reason why they might not have been counted. the 4 clicks were unique and only clicked 1 ad in my entire site for the day.
Now, after comparing with the rest of my channels, i am seeing these results everywhere, which easily explains why my revenue has dropped so significantly To note, this all really started after the update on the 19th. since then, I have seen higher "audits" on my clicks than can be explained.
If anyone has ideas, suggestions, comments or anything that could be helpful, it will be greatly appreciated. I would also suggest, those that are capable and suffering from sudden loss of revenues, to also run a similar experiment and report back. My opinion is that there is a glitch in the ypn system and we are not being paid for all valid clicks.
