What is search engine optimisation?

Hi all,
Can anyone tell me What is search engine optimisation?

SEO is the best way to bring the website at the top of the search engine with the help of keywords.

SEO or Search Engine Optimization is the process to optimize the site to increase the visibility of site in SERP (Search Engine Result Page)

Search engine optimization (SEO) is the process of improving the volume and quality of traffic to a web site from search engines via "natural" ("organic" or "algorithmic") search results. Usually, the earlier a site is presented in the search results, or the higher it "ranks", the more searchers will visit that site. SEO can also target different kinds of search, including image search, local search, and industry-specific vertical search engines.
