Apogee Search
Search Engine Marketing? I've heard the term thrown around here and there but to be honest I wouldn't be able to define it. I'd guess that it is similar to Search Engine Optimization but that would be just a guess.
Fortunately for myself (and anyone who might be reading this) I have found the definitive Search Engine Marketing Glossary. I learned from the Search Engine Marketing Glossary (among a lot of other things) that SEM means "the marketing of one's website through a search engine, whether through paid search or search engine optimization".
Out of curiosity and for comparison I looked up SEO also. The definition of SEO is "techniques used to improve a website's rankings in the search engines. Consists of on-page optimization, indexing improvements and link building." So now I know!
In addition to that great glossary, Apogee Search is one of the 25 largest Search Engine Marketing firms in the world. Not only the USA mind you, but the world. Even though Apogee Search is a global company and dedicated to helping clients everywhere, they do love to stay close to their southwestern United States roots and would like to continue that tradition by focusing on Houston SEO. Hear that Houston? Apogee Search is there for you. :)
