Another big benefit to using social media is that it can help you gain more influence, as well as grow your business across board. And although social media has little direct influence over your search engine ranking, it can help your SEO, albeit indirectly. By helping to grow your business and your website, gaining more traffic, more backlinks and so on, this will improve your website's domain authority, and thus, its search engine ranking by extension.
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.
