HTML Meta tags

HTML lets you specify metadata information about a document rather than document content in a variety of ways. The best way is “HTML meta tags”

The META element can be used to include name/value pairs describing properties of the HTML document, such as author, Expiry Date, a list of key words, author etc.
The <meta> tag is an empty element and so does not have a closing tag, rather, <meta> tags carry information within attributes, so you need a forward slash character at the end of the element.
Metadata provided by using meta tag is a very important part of the web. It can assist search engines in finding the best match when a user performs a search. Search engines will often look at any metadata attached to a page especially keywords and rank it higher than another page with less relevant metadata, or with no metadata at all.

Adding Meta Tags to Your Documents:

You can add metadata to your web pages by placing <meta> tags between the <head> and </head> tags. This can include the following attributes:

Attribute Description
Name Name for the property. Can be anything. Examples include, keywords, description, author, revised, generator etc.
Content Specifies the property’s value.
Scheme Specifies a scheme to use to interpret the property’s value (as declared in the content attribute).
http-equiv Used for http response message headers. For example http-equiv can be used to refresh the page or to set a cookie. Values include content-type, expires, refresh and set-cookie.
