Google will select the best title it wants for your search snippet – and it will take that information from multiple sources, NOT just your page title element. A small title is often appended with more information about the domain. Sometimes, if Google is confident in the BRAND name, it will replace it with that (often adding it to the beginning of your title with a colon, or sometimes appending the end of your snippet title with the actual domain address the page belongs to).
Use common sense – Google is a search engine – it is looking for pages to give searchers results, 90% of its users are looking for information. Google itself WANTS the organic results full of information. Almost all websites will link to relevant information content so content-rich websites get a lot of links – especially quality links. Google ranks websites with a lot of links (especially quality links) at the top of its search engines so the obvious thing you need to do is ADD A LOT of INFORMATIVE CONTENT TO YOUR WEBSITE.
Submit website to directories (limited use). Professional search marketers don’t submit the URL to the major search engines, but it’s possible to do so. A better and faster way is to get links back to your site naturally. Links get your site indexed by the search engines. However, you should submit your URL to directories such as Yahoo! (paid), Business.com (paid) and DMOZ (free). Some may choose to include AdSense (google.com/adsense) scripts on a new site to get their Google Media bot to visit. It will likely get your pages indexed quickly.
