SEO or Search Engine Optimization and SEM or Search Engine Marketing are related fields. Both initiatives attempt to improve a web site's visibility in the global network we call the internet by improving the frequency with which a typical user's keyword search on a popular search engine will return that web site at the top of the list. Getting your site to the top of the list is a complicated process but can be summed up in a few short words. Relevance, Authority and Popularity.
