Google Analytics has some unique features and is easy to install, learn and use.

Google Analytics even goes so far as to list keyword effectiveness by time of day (dayparting) and suggests keywords to buy. Content Optimization reports contain information on advertising effectiveness, top pages, navigational analysis, conversion funnels and technical statistics such as browser versions and screen resolutions.

In my opinion, G-A’s biggest weakness is that they do not offer the level of professional support required for most companies.
