Impression Discrepancy

[flyzone]

Lately I've been noticing quite a bit of discrepancy between the impression recorded by the ad server compare to other tools. 

 

Had to start monitoring after some clients complained that the number of impressions reported were not even closed to the numbers they recorded.

 

I'm monitoring the Google adsense impressions and compare them to the Revive ad server and in some days I can see a big gap. Like Google recording 8200 impression and Revive recording 13200 (number of clicks are the same)

 

In the banner logging settings the configuration is set as:

 

Log an impression every time a banner is viewed 

Should I use Log a request every time a banner is requested instead?

 

And not to log stats form 

Googlebot-Image/1.0

Googlebot/2.1

AhrefsBot/3.1

bingbot/2.0

YandexBot/3.0

VoilaBot BETA 1.2

 

Anyone have an idea why the difference is so wide?

 

Thanks

Hello,

I've quite the same issue, did you found a solution ?

 

Thanks

There are a number of reasons - and what I really need to do is create a troubleshooting guide for people to help them walk through understanding what the cause is.

 

I've added this to the documentation todo list...
