I've been using google analytics for about 3 months now, and I'm fairly fed up. A big part of what attracted me was that I could easily check and cross reference everything. However the data constantly seems to be *shit* The main problem for me is that analytics constantly thinks adwords (yes its setup with analytics and adwords properly), yahoo ads, and the msn ads that I have running are "organic searches" which basically makes it insane when trying to accurately determine the amount of organic traffic i have. Its not like I only have a few keyword phrases running, i have many hundred. Perhaps its time to get a better traffic analyzer that can actually give me accurate statistics about where my traffic is coming from. Any ideas?
I agree with ewan without paying the best free one available is defintely Google Analytics, I've been using it for 6 months and it meets all my current needs.
