Meta tags are used to provide information about a web page. The meta tags are optional and easy to use. There are three main attributes of meta tags: name, content, and http-equiv. The name attribute specifies the type of information. The content attribute includes the meta-information. (Access this page to learn how to use these two attributes to optimize your web page for search engines.) Lastly, the http-euiv attribute specifies a particular header type.
There are over a dozen of name attributes. The purpose of using name attributes is to provide information to the search engines. The following table summarizes the most common name attributes:
| Attribute name | Explanation |
|---|---|
| description | Description of the web page. |
| keywords | Used to list keywords that describe the content of the web page. |
| creator or author | The organization or person who responsible for creating the webpage. |
| date | The date of publication in yyyy-mm-dd format. |
| identifier | A unique number identifying a web page. |
| language | Language of the page. Use a two-character language code. |
| rights | Used for adding copyright statement. |
The http-euiv attributes are equivalent to HTTP headers and control the action of a browser on a requested page. When displaying, the browser uses the instructions specified by the http-euiv attributes. The instructions may contain information about when the content of the page will expire or when the page should be refreshed.
