I currently have 2 potential clients, both of which are small business owners looking to target people in the local area. As far as design and programming of their web sites go, I know what I'm doing. But when it comes to SEO, promotion, marketing etc, I'm far from an expert. I think to do a really great job for both of these clients I am going to have to come up with some ideas on attracting local customers to their business.

In what way can the web site and SEO help with that? What are some good articles to read to get me started and headed in the right direction?
