This question has several answers. First, your site isn't going to show up right away on search engines. You will have to give it at least a month for your site to appear on any search engine, generally. Second, the ranking you get in the search engines depends on the quality of information on your website. Descriptive text is a MUST. That doesn't mean you have to cover your site with text that most of your viewers will find annoying and won't read anyway, but you must have descriptive text with keywords that people may search for your site with.

Another thing that helps is having links to your website on other websites, so exchanging links with other websites is a great idea! Social networking is HUGE right now. Get a blog with a link back to your website, visit other blogs and comment on them, get a Twitter account, get a Facebook fan page, join a professional community like LinkedIn....all of these will help bring attention to your website and grow your business.

Meta title, description, and keywords are also a good idea (however, not as important as they used to be) to add to your products and pages when you're editing your site, and there are boxes for you to add this information when you create a page or add a product.

Now there are several companies out there that offer SEO (search engine optimization). BEWARE as most of these are not necessarily scams, but targeted towards people that don't know much about websites, and will willing charge you unnecessarily. With the hosts that I work with you can easily optimize your site yourself with descriptive text and meta tags.
