The content of your website is important for the search engines as they consider your website's relevancy and importance based on both meta tags and content in relation to the important keywords. There are several guidelines you should follow:
Include keywords in text
You should make sure that all those keywords you have included in your meta tags and on which searches you wish to come up are included in the text of your site.
Consider density of the keywords in text
Be careful not to overcrowd your text with keywords cause you might get penalized. Note that you should have the most important keyword(s) in the beginning of the page as thus they are given more weight. Refer to my previous post http://seo-news-master.blogspot.in/2013/09/how-to-place-important-keywords-and.html to know what should be the optimum density of the keywords.
Mind the formatting of the text
Formatting (bolding, titles, etc.) is also important to show the search engines that certain words are more important than others. Thus, if you bold your keywords in your text, they are perceived as more important than other words and thus your text becomes more relevant to these keywords.
Add regularly relevant content to site
You should make sure that you add relevant content to your website. This content addition invites Google to visit your site more often and increase its relevance and importance.
