Got Google Analytics running on one of my websites. Google defines a pageview as the most occuring event. Every refresh, every link clicked to a different part of the page, even loading from cache is an additional pageview [http://www.google.com/support/analytics/bin/answer.py?hl=en&answer=57164](http://www.google.com/support/analytics/bin/answer.py?hl=en&answer=57164) Now it should be known that GA is JS based, and will report directly to Google from the client’s browser that page X has been visited. This is why it can also count hits from the client’s cache. Now I have written my own little banner rotation system in one of my projects, which also contains a viewcounter. For testing purposes I have only 1 banner, and it is displayed on every page that is also tracked by Google Analytics. The viewcounter for my banners works serverside, and actually counts the times the banner was requested (times rendered on serverside to be precise) Now over a period of a month GA has accumulated around 150 views, where my banner system reports close to 1100. Almost a factor 10 difference! Now obviously both ways are pretty different. For example, my banner system will miss hits from the cache, where GA’s JS will be blocked by browsers that have JS disabled or are incapable of. And my system will also count visits that are terminated before the website got fully loaded where GA’s JS will only be executed at the complete page load. Has anyone got any experience with pageview counters and can you tell me if a factor 10 difference is acceptable? Because to me it seems it is quite a big and unreliable difference. ---

Do you filter bots and spiders? Because they visit very often websites. Maybe google filters them and you don’t? ---

My webalizer page view stats, for example, are about 8-10 times higher than what GA reports for page views. – Greg D. [http://destiney.com/](http://destiney.com/) ---

Is it not that GA only reports hits where the user has allowed his browser to send data to Google? I for example definitely do not want google knowing what I do so have disabled this. Or am I misunderstanding something? Colin 2009/3/30 Greg D. [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid)
