help with bad reporting.

reporting

[mconnors]

Maybe someone can explain to me if I am going insane, I would really appreciate it. I have a site that google analytics reports, 4,242,965 Pageviews for 30 days. We landed a contract for a banner on the site for a set # of impressions but only for certain states. Everywhere else we are serving up adsense.

Using a very simple php funtion to serve either clietns ad or adsense depending on geo targeting and then increment a count in a database when its served, very simple, I am getting for 1 day counts:

171,078 adsense
74,308 paid ad
245,386 total page impressions

Google analytics has counted page impressions for that day:
177,826

Google adsense reports page impressions for that day.
58,637

Mediaplex is reporting (clients ad):
9,340

How can all these numbers be that far off?!?

Not every client has javascript-enabled and not every adserver has same speed & response time.
