Google Analytics and Awstats reports do NOT match up.
They are supposed to show different data.
AWstats
AWstats (Advanced Web Statistics) is an open source log analyzer written in Perl that can use a variety of log formats. AWstats was designed with the main purpose to inform system administrators rather than website business owners, web marketers and web analysts, which basically means that making sense of AWstats data for marketing/business purposes is not very straightforward.
Google Analytics
Google Analytics is intended to be a measure of business (website) performance and provides you with statistics that a business person want to see. The current web analytics tools (of which Google Analytics is a big player today) is moving into an area between website statistics on one hand and business intelligence on the other. Web analytics develops towards the needs for business intelligence rather than raw webstat data.
