The description is a tag of the metadata used to briefly explain what the page is about. Like all metadata, the description also isn't displayed on the page and addresses primary search engines.


<meta name="description" content="Let me explain what this page is about...">

The description is used as a snippet from the page in the SERPs, beneath the page tile. If the description contains the search term, it will be highlighted in bold font.

The description should have the page's main keyword in it and shouldn't be longer than 200 characters.
