Another special mention is Quora. The question and answer site is like a high class, actually-useful version of the defunct Yahoo Answers. Experts find questions in their industry to answer and provide detailed answers, either in the form of a moderately lengthy post, or in a post that links out to their websites. You, too, can take advantage of industry questions by answering them the best you can. Users can vote on the most useful answer, and it floats to the top, so the more useful you can be, the more exposure your link will get.
The term “organic traffic” is used for referring to the visitors that land on your website as a result of unpaid (“organic”) search results. Organic traffic is the opposite of paid traffic, which defines the visits generated by paid ads. Visitors who are considered organic find your website after using a search engine like Google or Bing, so they are not “referred” by any other website.
