Actually - I think they do. But what's this have to do with websites, Brad, come on! I'll tell you what. 

Nothing urks a person more than unsolicited salesmen. Except spam. It's unsolicited salesmen delivered to your email fresh many times each day, and it's the worst thing in the world! Heck, half of these 'digital salesmen' carry deadly viruses, and give them to me without my permission! I never do business with a company that sells my email address to these idiotic spam companies. NEVER. 

And neither do your customers. This is why it's important that you have a good privacy policy available on ALL of your pages, down at the bottom where people expect it (see my Design Practices post). And anywhere you ask for an email address, it doesn't hurt to put it there either. 

The most important thing about a privacy policy is that you spell out as clearly as you can HOW you use customer data. This is not the place for legal mumbo jumbo, but it should be clear, concise, and easy to read. If you want a good privacy policy to use on your website, take a look at ours and feel free to copy it and alter it for your own use.

Don't forget - misguiding your visitors in your privacy policy by "forgetting to tell them something" is against the law (as it should be), and it will KILL your great reputation! With a good reputation, you'll be able to develop solid, repeat customers. Speaking of which, come back tomorrow for a special post where I tell you how to keep your business on the CUTTING edge of what people want!
