Important tips for good Meta description tags:

* Use keywords in your meta description tag.
* Try not to repeat the words overly often, but try to use multiple syntaxes of your key words.
* There should not be more than 150 characters in a description metatag of a single web page.
* Use a different meta description tag for each page, as each page is different and stands a better chance of being found if you place a good title and description on it.
