SEO, or Search Engine Optimization, is the process of improving the quality and quantity of website traffic to a website from search engines. SEO strategies typically focus on improving a page or site's position on SERPs (Search Engine Results Pages) and ensuring that search engines can easily crawl and index the content that is to be ranked. Unlike SEM (Search Engine Marketing), SEO is a method for driving unpaid traffic to a website and does not involve the direct purchase of a position in the search results. Google routinely updates its recommended best practices for SEO, which means that strategies must be changed over time.
SEO articles explain how users can optimize their content and sites for search engines. These articles may include how tos, guides, or strategies for improving a site's keyword positioning and discoverability among other topics. Topics related to SEO include search engine marketing, app store optimization, content marketing, and web design. Additional topics related to SEO include website usability testing
