I just thought of something a bit more concrete...

Don't sell/trade/give information about your users unless you are very, very clear in your TOS/Privacy policy that you are going to.

Marketing data is worth $$. I've known webmasters who look at it as easy money, and are all to willing to sell analytics data to whoever ponies up a cheque.

If you use a third party analytics solution, then say so in your TOS/Privacy policy. And be aware of that third party's privacy policy. On sites where I have Google Analytics, I say so. I don't trust G to play nice with my traffic data, so it's only fair I let the users know this.

If your advertising solution uses cookies and tracking data, the rule above also applies.

A great many websites play fast and loose with their user data in pursuit of $$. It's become almost accepted. That doesn't make it right.

(side note: perpetually moving sites off Google Analytics. The data provided is wonderful, the service is easy to use and great. I'm just not super keen on giving Google even more info).
