Make sure that all the pages of the site have custom titles and descriptions.

your site is using the same tags for all the pages, you are not helping search engines figure out the subject or relevance of your individual pages. Regarding Meta Tags, there are 2 very important fields:

• Title Tag - arguably the most important SEO tag for any website. Google supports approx. 60 characters in the title
  
  
  , while Yahoo allows for up to 110 characters in the title. It is important to target the most critical keywords in the Title. Every page should have a unique Title.
• META Description Tag - These were once important but are no longer. Some engines do display the description defined, while others do not. Some search engines do read the description tag, and do utilize the content found within in the ranking process. Google, MSN and Yahoo give very little weight to no weight for these.
