White Hat SEO focus on building quality content first and SEO second. White Hat SEO may use technology and automation to build their websites too, but they use it to accomplish different goals. They write content for people, not search engines. White Hat SEO tend to rely more on their content and marketing skills to achieve a top ranking, rather than automated programs.

Gray Hat SEO is all about risk versus reward. Some Gray Hat techniques may be frowned by the search engines, but are not necessarily against their rules, while other techniques may be more risky and should be used only after careful consideration.
