Remember to update your website frequently. The more often you update it, the higher your search engine rankings will go.
Also, of course, be sure to create relationships with the Top 30 websites you find when you type in your key search terms (how you think people will find you) in Google or Yahoo. To create relationships with those websites, ofter them a review copy of your book, an interview with the author (that's you), or an excerpt from your book that would be valuable for their visitors.
