Reports in my account don't match my own statistics

We count page views and impressions only when our ad code is executed by a user's browser. So there are several factors that would cause a discrepancy between the statistics you register in your logs and those listed in your AdSense account.

Instances that wouldn't execute the code include:

• Spiders, robots, or crawlers from other search engines
• Browsers that don't have JavaScript enabled or don't support JavaScript
• Browsers that don't support the <iframe> tag
• Programs that people may have written to grab website content

Another reason why you might find a difference between your AdSense reports and your own statistics is invalid activity. We remove clicks and impressions derived from some forms of invalid activity from our reporting data, so you might notice slightly higher metric values for clicks and impressions in your own statistics.

Also, if your pages display multiple ad units, keep in mind that AdSense shows multiple ad unit impressions for each page view.s
