I don't think you should focus on learning the many facets of SEO while trying to deliver a product but there are some quick, actionable pieces of advice which are undisputed enough that you can pretty much blindly implement them. A great place to learn about seo (especially as it pertains to software products and marketing them) is patio11's blog. A particularly relevant, however short, article is http://www.kalzumeus.com/2006/10/02/object-lesson-on-blogging-for-your-business/ http://www.kalzumeus.com/2006/10/02/object-lesson-on-bloggin... which speaks specifically to this point. Also, I would recommend getting as many support tickets as possible. Not only are they feedback from users about what the product needs (you're probably aware of how important this is considering it's the mantra of every notable writer in the startup/saas domain) but they represent people who a.) are interested enough in your product to complain that they can't use it yet and b.) have implicitly given you permission to contact them. A simple, "This will be implemented soon. I'll email you when it's ready." makes the immediate problem disappear while creating a list of users primed and ready to start breaking your software for you when it hit beta and beyond.
