I have just read an amazing blog posts by Avinash Kaushik – Google’s Analytics Evangelist (among other things):
Best Web Analytics 2.0 Tools: Quantitative, Qualitative, Life Saving!
It is a great list of web analytics tools, and you also get an explanation of how to make sense of all the data the tools are puking up and ultimately make more money.
Before you diving into Avinash’s blog post, I want to give you a short explanation of the difference between qualitative and quantitative analysis, otherwise it may be a bit confusing.
Quantitative: Measuring things with numbers fx. the number of visitors.
Qualitative: Things can’t measure with numbers fx. asking your visitors why they choose your site in the search results.
The post is long, so go make a cup of tea and a piece of paper to scribble down notes on before you get started. Read the post on Avinash’s blog.
