# Learn Search Engine Optimization > Search engine optimization (SEO) is the process of affecting the visibility of a website or a web page in a search engine's unpaid results - often referred to as "natural," "organic," or "earned" results. In general, the earlier (or higher ranked on the search results page), and more frequently a site appears in the search results list, the more visitors it will receive from the search engine's users. SEO may target different kinds of search, including image search, local search, video search, academic search, news search and industry-specific vertical search engines. - wikipedia ##### General Learning: - [SEO Fundamentals from David Booth](http://www.lynda.com/Analytics-tutorials/SEO-Fundamentals/187858-2.html) [watch][$] - [SEO Fundamentals from Paul Wilson](http://www.pluralsight.com/courses/seo-fundamentals) [watch][$] - [SEO for Web Designers](https://webdesign.tutsplus.com/courses/seo-for-web-designers) [watch][$] - [Google Search Engine Optimization Starter Guide](http://static.googleusercontent.com/media/www.google.com/en//webmasters/docs/search-engine-optimization-starter-guide.pdf) [read] - [SEO Tutorial For Beginners 2015](http://www.hobo-web.co.uk/seo-tutorial/) [read]
