Definition - What does Organic Search mean?
Organic search is a term for search engine results that are naturally generated and not influenced by commercial relationships between an organization and a search provider, ISP or other party hosting search results. This is in contrast to paid search results, where prominence on a given platform is purchased by an advertiser as a commodity.
Typically, Web users pay more attention to organic search results, or try to focus exclusively on these types of natural results. However, paid search results, like other forms of online promotion, do have an effect on their audience.
