Natural Search or organic search, is the process by which Internet users find websites by using search engines like Google, that have unpaid search engine listings, as opposed to pay per click advertisement listings displayed among the search results.

Search engine optimisation, (SEO), is concerned with maximizing the findability of a website by making its listings appear more prominently in natural search results. SEO is the science of researching the right keywords users adopt to find a particular product or service and ensuring that the website reflects these keywords.
