A meta description is a tag that summarizes the content of a page . Meta tags are not displayed on a page, but are located within the HTML code of a web page as: <meta name=”description” content=”A page’s description.”/>. Meta tags can be viewed by selecting view/source from a browser’s menu. Meta descriptions are a key SEO component. They allow crawlers to properly identify the topic of a web page so that the correct page is returned in SERPs.
