Meta Tags

Meta elements are HTML or XHTML elements used to provide structured metadata about a Web page. Such elements must be placed as tags in the head section of an HTML or XHTML document. Meta elements can be used to specify page description, keywords and any other metadata not provided through the other head elements and attributes.The meta element has four valid attributes: content, http-equiv, name and scheme. Of these, only content is a required attribute.Meta elements have significantly less effect on search engine results pages today than they did in the 1990s and their utility has decreased dramatically as search engine robots have become more sophisticated. This is due in part to the nearly infinite re-occurrence (keyword stuffing) of meta elements and/or to attempts by unscrupulous website placement consultants to manipulate (spamdexing) or otherwise circumvent search engine ranking algorithms.Meta refresh elements can be used to instruct a Web browser to automatically refresh a Web page after a given time interval. It is also possible to specify an alternative URL and use this technique in order to redirect the user to a different location. Using a meta refresh in this way and solely by itself rarely achieves the desired result. For Internet Explorer's security settings, under the miscellaneous category, meta refresh can be turned off by the user, thereby disabling its redirect ability entirely.
