Keyword- Putting your message in front of people who are searching using particular keywords and phrases.
Tag- A tag is a generic term for a language element descriptor. The set of tags for a document or other unit of information is sometimes referred to as markup, a term that dates to pre-computer days when writers and copy editors marked up document elements with copy editing symbols or shorthand.
