The problem is that the reports we are receiving regarding ad clicks to our landing page do not match and are not close. I have read some threads on this forum previously regarding similar issues but this one seems to be different.
The ad agencies consistently reported more clicks than we see on our Google Analytics. The percentage of variance is not consistent.
Here is an example:
Agency 1 - Reported 10183 clicks but our GA shows 3304 clicks - these are going to a unique url for this campaign only.
Agency 2 - Reported 8200 clicks and our GA shows 2100 clicks - going to another unique url for this campaign only.
Any ideas? Is GA not capturing a significant portion of traffic to our site? or do ad agencies use some settings to boot clicks and show better CTR?
