Accroding to USA Today, they recently asked Matt Cutts from Google for tips to help sites rank in higher in their search engine. He has summarise 5 tips and a word of advice in implementing the tips. 

1. Spotlight your search term on the page. If you want to be found for your keyword, make sure that term is on the page you want to rank. The term should be at the top as well as peppered throughout your copy.
2. Fill in your tags. The two most important tags are Title and Description. That's what is displayed on the search results.
3. Get other sites to link back to you. This is one of the most important of the 100 factors Google considers when ranking sites
4. Create a blog and post often. This can help you get links.
5. Register for free tools. Cutts recommends using the tools at google.com/webmaster, as well as creating a text-based sitemap www.xml-sitemaps.com, and adding your business to Google's Local Business center (google.com/local/add)
