Think first of who your target 'audience' is. What sort of people are they? What would keep them entertained after they've put your book(s) down? It might give you an idea of how to pitch or present your work.
Think next of a multi-pronged 'attack' on the market. When you publish your book through an independent publisher they put your book on the virtual market - Amazon, Waterstones and so forth - and you can check through Book Butler how your book appears there.
Got a picture yet? I first put together a page here, dedicated to the first of a (projected) series. I was put onto a website, Webeden, that offers free sites as well as more advanced ones. So I opened up a free one. Have a look at www.webeden.co.uk and see if it 'speaks' to you. There are multiple options, and you create as many pages as you need. A banner on each page shows the titles of pages you've created. Full instructions and options are shown at every stage. I've also opened a set of pages - free again - on My Book Buzz. Take a look at the site, it's based in Portugal. Look also at the Amazon site. An author blog is available, where you can place any talks you give, or events you'll attend, for your readers to visit and buy your books with you there to sign their copies. Tell your readers what's in the pipeline, what's about to be released and when (roughly). Penultimately, put yourself on LinkedIn. Build your profile, tell them as much as you want them to know, personal background, education, interests etc. You market yourself and your books there. Lastly, Twitter can help spin your image. Give your followers enigmatic little messages about your books, espouse causes, follow others and circulate (like at a book launch party).
Have a good time.
