Search engine optimization (SEO) is a specialty that is intricately woven into many other disciplines: website design/development, information architecture, copywriting, website usability, analytics and conversion analysis, etc. Successful SEO hybrids are web professionals who are equally skilled in SEO and another area of expertise. For example, many search-savvy web developers understand how search engines access content on a website, and they make it as easy as possible for search engines and searchers to access that content.
