As its name implies the description meta tag should describe the page, truthfully but should also be composed to contain the keywords you are targeting to further higher your ranking on those keywords. description Meta Tags directly represent what will appear as the "summary" of your web site. This will be displayed after the title of your website in any search result and when it is a true description, It helps further target the visitors you want to visit your website. The description should clearly communicate what a visitor to your web site should expect to find when linking to your site, most search engine users will not respond and open a search result that does not contain a short explanation of your page. You should try to embed the keywords within the description in a natural manner to appear the way it should in an engine listing. This makes the Description Meta Tag a great opportunity to emphasize keywords and add more key phrases to all of your web pages!
