HTML lets authors specify META data -- information about a document rather than document content -- in a variety of ways.
For example, to specify the author of a document, one may use the META element as follows:
<meta name="Author" content="Pete R Raleigh">
The META element specifies a property (here "Author") and assigns a value to it (here "Pete R Raleigh").
The meaning of a property and the set of legal values for that property should be defined in a reference lexicon called a "profile". For example, a "profile" designed to help search engines index documents might define properties such as "author", "copyright", "keywords", and "description".
For some search engines to index your site you need to generate META tags containing information describing your web site. Other search engines use "spiders" to index a site automatically counting characters, keywords, and tags.
I can advise and generate the required META tags for your site.
