Search Engine Optimization (
SEO) and Search Engine Marketing (SEM) are Two different things altogether. The two things go hand in hand but are often thought of as one thing. Search Engine Optimization is what is done to your site to ensure that the end users have a friendly easy to use web site with SEF Menus and SEF URLS that Google, Yahoo, MSN and Ask.com crawl through and find your content. Search Engine Marketing is doing the advertising and marketing of your site. Ironical this is all done "offsite" whereas
SEO is mostly done "onsite".
SEO is a more technical process than SEM and involves a deeper understanding of search engine algorithms.
