What Is SEO?

These days I am afraid even a snail knows what SEO is about. Then what is exactly search engine optimization? To get the definition of SEO, I recommend a marvelous site with massive information on this subject: www.sempo.org

If you click on Learning Center, you will see an excellent glossary on all the Search Engine Marketing terms. According to SEM, Search Engine Optimization is the act of altering a web site so that it does well in the organic, crawler-based listings of search engines. In the past, has also been used as a term for any type of search engine marketing activity, though now the term search engine marketing itself has taken over for this. Also called SEO. This should make it clear what SEO is.
