What is a Meta Description?
Meta description tags, while not that important to search engine rankings, are very important in gaining valuable user click-throughs. These short paragraphs are a great way to advertise content to searchers and to let them know exactly whether the given page contains the information they're looking for.
The meta description should utilize the keywords intelligently, but also create a compelling description that a searcher will want to click. Direct relevance to the page and uniqueness between each page’s meta description is key. The description should optimally be between 150-160 characters.
