There are a couple of choice bits about analytics in general as well:
Why You Should Use Analytics
The fundamental reason you want to use analytics is because it lets you know how your customers interact with your site and that this drives
decision-making about your site design, future business directions, and the
like.
You might say “Wait, why don’t I just talk to customers?” You should talk to
your customers, but customers:
have more important things to do than talk to you
are not experts about your site
misremember things
resent being tested on like rats in a twisted science experiment (“Would
you hit this bar for cheese more if it was green, or blue?”)
Analytics has none of these problems. The data you collect:
is always there, waiting for your analysis
is totally expert on use of your site
is as accurate as your collection method
has no issue with answering arbitrary, inane questions
It’s fantastic to see people using analytics to drive their business forward.
