Long-Tail Keywords are highly targeted search phrases (for SEO) which contain three or more words. A long-tail keyword usually includes a head term (a more generic search term), as well as one or two keywords to refine the overall search term. Example:  Head Term: Coach Long-Tail keywords: Marketing Coach, Business Coach for Solopreneurs, Local Marketing Coach, Marketing Coach for Business Owners Because Long-Tail Keywords are more specific, the visitors that land on your website as a result of a long-tail search term are more qualified, and consequently, more likely to convert.
