Search Engine Optimization (SEO) is a highly competitive industry focused on building competitiveness for online businesses through natural search. Having your business show up in the top 10 of Google for a largely search keyword or keyword phrase is better advertising than pretty much any other...because it's absolutely free. Knowing seo can put you there.
To give you an example of its regarded importance, seo.com was purchased for a cool $5,000,000 dollars (domain only)! Only few others have had higher price tags.
