Metadata is information about data. The metadata for an HTML page does not show up when someone is viewing your web page; it’s a part of the HTML code, located in Head section of your page.
Metadata allows you provide data for what the search engine may need to know about your page.
For example, the title and description tags enable you to name and describe your page. With metadata, you can also specify other issues, like the language used on your page, the author of the page, etc.
