You can minimize the counting differences by putting cache-busting code
into the agency's tag. The agency should be able to give you the right
syntax and AdForce should be able to help you generate a random number.
The reason that you're seeing the counting discrepancy is due to
caching. I'm making an assumption here but I'm guessing that you're
loading the agency tag into AdForce as a redirect.
When a user first comes to Upside, the AdForce tag is called and AdForce
counts the impression. AdForce figures out that the campaign it needs
to serve is actually the agency's campaign and it issues the redirect.
Then, the agency's ad server is called, an impression is counted on
their end and the banner is served. The second time in, the AdForce tag
will once again be called and AdForce will count the impression.
However, the agency's tag (the re-direct) will at this point be cached
(probably on a proxy server). The agency's ad server will never be
called and though the impression will be served (from cache) it will
never be counted. So, from the agency's point of view, you will always
be under-delivered.
Adding a random number to the end of the agency's tag will force the
proxy server to view the agency tag as unique - therefore, the agency's
ad server will be called and an impression will be counted on their end.
We've found that when using AdForce, redirects without any cache-busting
code can be off by as much as 40%. Once we added the cache-busting
code, the discrepancy is reduced to about 5%.
Hope this helps. PS. I second your emotion regarding standardization.
It will be a great day when all of the ad servers start counting the
same way.
