The bedrock of any Internet marketing campaign should always be SEO, or “Search Engine Optimization.” The goal of SEO is to get your site to show up organically in the first few unpaid search engine spots for specific search terms or keywords people type into search engines such as Google or Yahoo. Many might confuse SEO with SEM, but there are key differences. The most notable is that SEO is considered organic marketing. It isn’t hard to guess why this is so valuable for any business.
