SEO is an acronym of Search engine optimization. It is a step-by-step process to rank a website higher in the search engine result pages following the guidelines of the search engines, especially Google.

The results are ranked based on the relevancy of the search term to the content on the landing page. A user searches and a list of results highly related to what the user is searching are displayed.
