Be sure to use several of your keywords in your description. Search engines that look at pages for a description meta tag, will use the contents of that tag in its search index. The description is presented to the user along with the document's title as the result of the search. Many robots will use the first few lines of text on your page as a description if the description tag is not present. This tag provides keywords for search engines to associate with and index your page.
Some robots look at keywords in context, so it is best to preserve a logical word order and case.
Don't load the keywords by using the same word repeated over and over, as most search engines have been refined to ignore this. The author meta tag is used to indicate who the author of the web page is. The TDH Web Office maintains the main branches of the TDH website, provides technical assistance to its web developers, and ensures TDH website compliance with all applicable DIR rules and guidelines. That's exactly what the meta description tag does. It lets you control the description that appears.
