Bottom line, nothing beats word of mouth advertising - but if you want your site to get picked up by people 'surfing the web', you'll have to put some time and effort into SEO. 

SEO, or Search Engine Optimization, is the process of enhancing a website to better the chances of it ranking highly in the search engines. 

How it works:
Search engines crawl the Web to see what is there using software known as a crawler or a spider (or Googlebot, as is the case with Google). Spiders follow text links from one page to another and index everything they come across. Because there are over 20 billion Web pages on the Internet, it is impossible for a spider to visit a site daily just to see if a new page has appeared, or if an existing page has been modified. Sometimes crawlers will not visit your site for a month or two, so during this time your SEO efforts will not be rewarded. But there is nothing you can do about that.
