Why would anyone not want to know how many people are coming to their site, what are these people doing when they get to the website, where are these people going when they leave the website?
Google Analytics has become the standard in website analytic programs which is why Marketing Buddah recommends installing GA on every website we work on. Additionally to just installing GA code on websites we also work to setup Goal tracking, Event tracking, Ecommerce tracking, Campaign tagging, Adwords linking, Custom reporting, and more.
The great thing about Google Analytics is that you can get as granular as you want with the data or you can view from a 30,000 foot view.
Here is a great checklist that Google provides if you want to take a swing at setting up GA on your site :
