HTML Meta Tags


HTML lets you specify metadata - information about a document rather than document content -in a variety of ways. 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 tag is an empty element and so does not have a closing tag, rather, 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 tags between the and tags. The can include the following attributes:
AttributeDescription
NameName for the property. Can be anything. Examples include, keywords, description, author, revised, generator etc.
contentSpecifies the property's value.
schemeSpecifies a scheme to use to interpret the property's value (as declared in the content attribute).
http-equivUsed 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.
NOTE: Core attributes for all the elements are discussed in next chapter.

Meta Tag Examples:

Document Revision date:

This information tells about last time the document was updated.



Document Refreshing:

You can specify a duration after which your web page will keep refreshing. If you want your page keep refreshing after every 10 seconds then use the following syntax.



Page Redirection:

You can specify a page redirection using Meta Tag. Following is an example of redirecting current page to another page. You can specify a duration after which page will be redirected.
