Analytics measures what you want.

If you want sales, then you're also gonna want to evaluate the sales funnel to see where friction in the online sales process can be reduced, and if you're big enough do some fancier things like A/B testing.

I will agree that a lot of people look at analytics often far too divorced from their business goals. If you care about sales of X, then you probably shouldn't be too invested in regularly looking at most of the big site level metrics unless you're trying to alter those to improve sales of X.
