There are several factors that can make our stats lower here than in Google Analytics. Here are some of the most common reasons:
Our stats only count the pages that have the ad code installed correctly on your site, so if there are some sections or pages where you do not have your ad code installed or some pages in which the ad code is not installed correctly, then impressions on those pages will not be counted.
Our counts exclude impressions from people using browsers with ad blockers turned on, so those impressions will not be counted.
Our counts and Google's counts are not for the same time period. When our system estimates impressions for the first time, it calculates the first 7 days worth of data and then multiplies that amount by 4 to give an estimate for the first month. After you have been in our system for more than a month, then the impressions from the previous 30 day period is presented, so our counts are not for the current time frame that you are seeing in Google.
If you have your Google Analytics tracking code installed twice, it can double your counts at Google, which is not the correct count.
If you have your ad code installed incorrectly, it can cause counting issues. You cannot have the STEP 1 code twice in a page, and the STEP 1 code must be just after the openingtag of your site.
If you have your "Max Banners" in a zone set to an amount greater than the "Banners" displayed in that zone, then it reduces the amount of estimated impressions for each advertiser since ads in that zone will be rotated. This also creates a lower amount of estimated impressions displayed for that zone on your Ad Detail page - which will also be lower than the total impressions of your site that you see in Google Analytics.
Our counts are more accurate than Google's counts for the purpose of selling our ads since we only count the pages with the ad code installed properly, and we only count impressions for those without ad blockers. This protects advertisers from being given impression estimates that are more than what they may actually receive.
