Discrepancy ?

Some discrepancy must always be accepted when you are dealing with third party adserving. The counting of the impression is always later in the chain for the 3rd party ad server.

Examples of reasons for discrepancies which no ad serving party or site owner can be
held responsible for are:

-   Slow connections
-   Browser shut downs
-   Fast page changes or reloads
-   Internet related problems, connection problems, packet losses etc.

Problems caused by the elements on the site can be:

-   Slow loading site – other elements on the site where Pantaumaya tags are placed which prevents third party ad from loading
-   Other campaigns which conflict with the actual campaign and disturbs the requests.

Then there might also be issues of which the third party ad server is held responsible:

-   Advanced ads with advanced functions and scripts which all browsers/users can not load
-   Server problems at the third party machines with long response times
-   Server failure at third party

Industry standard say 10% is the upper limit of acceptable discrepancy and everything between 0-5 % is absolutely normal. The more advanced ads we see and the more advanced sites they are running on – the higher is the likely discrepancy.
With an unlucky combination of the factors above it is not impossible the discrepancy has its natural causes.

Procedure when discrepancy above 10% occurs.

1. Always try to find a discrepancy issue as soon as possible during the lifetime of the campaign. It will be a lot easier debugging the problem with the campaign running live and you still have a chance to make everything right before the campaign has ended.

2. Compare your stats with the other ad server and see if you find any patterns e.g. if there is one day where one ad server is not delivering, If you find a clear pattern or an explanation please check the validity with the 3rd party provider.

Don’t hesitate to contact Pantaumaya Support to validate your theory.

3. If nothing is found, please contact the Pantaumaya Support and provide all necessary information gathered in the process. Please also include a URL or a tag where we can see the campaign running live – this helps a lot.

4. The Pantaumaya Support Team will get back to you after investigating the issue.
