I have two different advert groups for my top banner, one showing on desktop and one showing on mobile phones, and the tracking of impressions must be wrong. The numbers are very low even though the ads rotate frequently and the page has got many visitors.
The Weird thing is that this only happens on these two advert groups. I have a total of 5 advert groups and on the 3 other advert groups the statistics seem to be normal. All groups have 4 ads each. Tracking of clicks works on on all 5 groups.
I have tried to roll my whole site back to the oldest backup available withouth any luck. The site is hosted on WP Engine and uses their cache. It is a single site.
We decreased the impression timer to 60 seconds and it helped a little bit. But it is still far from our goal to have the views increment continuously. Basically a visitor visits the site we want the views to increment directly and not after several hours and there count is still wrong.
We tried to disable the current ads and make our own so that there wouldn’t be anything wrong with the ads, but this problem still persist.
So basically we think that there is something wrong with the plugin. We have done quite many tests besides this.
