The implementation of an analytics, testing or targeting tool is a crucial step to a successful website. It allows the analyst to trust the data and take data driven decisions. An accurate Marketing Measurement enables the marketer to allocate budget to the most profitable acquisition channels and to provide the best user experience to both new and returning visitors.

Even though Google Analytics is great, there is always one or two improvements that wouldn't hurt. This article presents 3 features that could enhance the tool: Adsense ecommerce integration, Marketing Campaign Import API and Website Optimizer & Webmaster tools integration.
Daniel Waisberg -
The most important question in web analytics is “Why?”. The answer to every “Why?” in web analytics is also “Why?”. This is one of the (many) great challenges in the field, but it is also what keeps the practice of web analytics fresh and interesting. There is no end point. There is no perfect site. There is only “Why?”. Having said that, there is sometimes a “Because of...” - but that usually means “Probably due to...”.
