Glossary of Search Engine Marketing (SEM)

This is a very insightful web page that I came across when looking up the definition for "Long Tail Keywords" that helps a novice like me get a better understanding of e-commerce marketing strategies.

in reference to:

"Long Tail Keywords Long tail keywords are keyword phrases composed of three or more words that collectively are more specific than a single keyword. Long tail keywords are more likely to convert to sales than shorter, more generic keywords because there is less competition for them. Generally, the more specific the search, the closer the searcher is to the act of purchasing a product or service."
