Then you’re called a Web Developer. Good web development includes using proper formatting (like putting headlines in H tags) and understanding how the web works, search engines included. Valid code also has the side-effect of making your pages more accessible for your users, which is the point. Making your pages more accessible to robots is for robots.
I've been trying to put that idea into words for a while. I visit a lot of forums and freelance sites to prowl for good work, and I see many discussions about page rank, inbound links, three-way links, hosting pages on different IP's to get more PR juice for all of them, etc etc.
It just seems like it's a backwards way of going about things, like building a super highway to a place you hope there may be a city in the future.
Good development of a good service and spreading the word about it is what's needed to get customers.
Just an aside...
Did you just quit smoking or something?
Yes.
I just quit cold turkey.. it sucks. Wish I'd never smoked in the first place.
