The term “organic traffic” refers to users that arrive at your website as a consequence of unpaid (“organic”) search results. Organic traffic is the inverse of sponsored traffic, which refers to visits produced by paid advertisements.
Organic visitors see your website after using a search engine such as Google or Bing, and they are not “recommended” by any other website.
Organic traffic is gained by the site appearing in the results of a search performed by users in search engines such as Google, Yahoo, or Bing. Organic traffic is free traffic, which is why it is the form of traffic that website owners like.
When users enter a query into a search engine (such as Google or Bing), they are provided with a set of results that includes both the pages ranking in the top organic positions and a collection of adverts (typically labeled with the term Ad) to separate them from the organic results.
