Hi guys, I have statistical data gathered from 4 different tools to measure web traffic: Google Analytics, AWStats (portal and ws), SAS and Piwik. The data from those tools differs significantly. The problem is I need to include the basic figures in my report such as unique visitors, visits and pageviews. Which tool gives me the most reliable data in each category? Some people say that AWStats is great for collecting stats on unique visitors. What about the others? Many thanks!
