SEO means Search Engine Optimization and is the process used to optimize a website's technical configuration, content relevance and link popularity so its pages can become easily findable, more relevant and popular towards user search queries, and as a consequence, search engines rank them better.

Search engines recommend SEO efforts that benefit both the user search experience and page’s ranking, by featuring content that fulfills user search needs. This includes the use of relevant keywords in titles, meta descriptions, and headlines (H1), featuring descriptive URLs with keywords rather than schema markup to specify the page's content meaning, among other SEO best practices.

The goal of SEO is to raise your ranking in organic search results. There are different practices for optimizing AdWords, shopping, and local results. While it may appear that so many competing elements taking up real estate on SERPs push the organic listings down, SEO can still be a very powerful, lucrative effort.
