"Organic listings" refer to the "real" search results, i.e. search results that are listed by the search engine bots because they detected a web page. These are different from the "paid listings," which occur due to a contract between website operators and search engine operators. These effective advertising measures set themselves apart from the organic listings. Paid listings can be recognized as advertising due to features like colored accentuation and arrangement. With Google, for example, paid listings are located at the top of the screen, above the "real" search results, as well as on the right of the screen.
