Definitions for "Meta Tag"
Keywords:  tag, keyword, html, hidden, robot
As part of the HTML header of a web page, a Meta tag provides valuable information to the indexing spider (for the purpose of better indexing) that is not visible to web browsers. Content within the Meta tags, such as the TITLE, KEYWORD and DESCRIPTION Meta tags are highly regarded by many of the top search engines and may factor prominently in how your pages are ranked.
A hidden HTML code on a Web page, containing keywords that describe the page's contents. Search engines use the information in the meta tags to produce search results. The Media Awareness Network's meta tags, for instance, include words such as "media," "education," "lessons," and "teachers."
A construct placed in the HTML header of a web page, providing information which is not visible to browsers. The most common meta tags (and those most relevant to search engines) are KEYWORDS and DESCRIPTION. The KEYWORDS tag allows the author to emphasise the importance of certain words and phrases used within the page. Some search engines will respond to this information - others will ignore it. The DESCRIPTION tag allows the author to control the text of the summary displayed when the page appears in the results of a search. Again, some search engines will ignore this information.
