Search Engine Optimization (SEO) involves designing websites, and getting links from other websites, to make your website optimally appealing to search engines. The result is higher rankings in the search engine result pages, which in turn leads to more traffic to your site from potential customers, more income, and increased brand recognition.
Many people and companies find that SEO is the most cost-effective form of marketing in existence, especially when it is part of an integrated marketing plan that includes public relations and online advertising. Once high rankings are achieved, they tend to stick unless you are in a very competitive niche. Those rankings cost you nothing, yet they can continue to bring you an unlimited amount of new customers and revenues.
