I have an interesting problem I am hoping someone has some insight on. I've noticed recently that of my three page view tracking mechanisms, they are all very different in what they report.
For example, here is one day Feb 21st:
OpenX reports 59,258 impressions on a certain zone, one that is on every page of the site (leaderboard)
Google Analytics reports 118,918 impressions for that day
Webalizer reports 210,923 impressions for that day
That is quite a difference. I know that sometimes webalizer has been accused of not being accurate, though I am sure that I have taken HTML files out of the equation (I PHP files). Google uses a Javascript to track impressions. OpenX is what I would THINK would be the most accurate, but obviously I'd like to think otherwise. As far as reliability goes, I'm tempted to think I would trust Google the most....
What would make these kinds of differences? Would ad blockers that read the site really be blocking that high a percentage of the ads?
Just for giggles, I'll pick a day with lower traffic.
Feb 14:
OpenX reports 32,125
Analytics reports 58,608
Webalizer reports 74,244
In this case the OpenX:Analytics ratio is pretty similar as the 21st numbers, but Webalizer is much LESS off than it was.
Basically, I am just looking for advice on what to look into. Thanks!
