awstats reports 77000 page views for one day of my website.but sitemeter and google analytics report about 28000 page views per day. which one is reliable?
well this throws a up a disparity in results with awstats, somehow i would rely on google analytics. and moreover sitemeter too is conforming in results with GA.
Neither analytic mediums is 100% accurate because each is measuring different things. For example, Awstats works from the actual server logs and does its best to extract information from that. google is only tracking those of your visitors with JavaScript enabled and so will miss out on around 6-10% of your visitors completely. In any case trying to estimate such things as unique visitors when all you have to go on is the IP address (where the same address can be used by many different people and the same person can have different IPs at different times) will give different results depending on exactly how it determines whether multiple page loads are likely to be the same person or not.
