After running some recent analysis on site logs, I have been finding that our AWStats visitor and unique visitor figures have been coming in around 54% (just over half) the size of the figures that NetTracker is reporting. Just wondered really if anyone might have any obvious idea of what the problem may be caused by, and if it might be an obvious problem that is causing it? As you can imagine it does have quite a drastic impact on conversion figures. Initial feeling is that the smaller AWStats figure is the 'most correct' number, but i would like NetTracker to be able to obtain a very similar figure to this.
There are a number of factors involved that can cause the difference in numbers from different tools. How the tool identifies a visitor (Cookie, Username, IP/User Agent). If the tool handles Robots and Spiders properly. Redirection and Errors. Inclusions and Exclusions.
Please send me a message and I would love to work with you so you understand the differences.
