Search engine optimization (Ŏp'tě-mĭ-zā'shěn) n.
Search engine optimization (SEO) is the process of making your website easy to find on the internet. This is done by optimizing your site for the search engines that people use to surf the internet. A well optimized site can draw thousands of (free) referrals per day from major search engines. Properly optimizing your site will mean a gradual shift away from Pay-Per-Click campaigns to cost-free referrals.
