A META Tag is the hidden text placed in the HEAD section of your HTML page. META Tags are used by most major search engines to index websites based on their keywords and descriptions. It is very important to use META Tags as well as a good TITLE if you expect to be found in most search engines. However, META Tags are not the only thing search engines will look at when ranking sites. Some search engines will ignore META Tags completely. Most search engines will also index your body text.
