Organic traffic refers to the visitors that come to your website as a result of unpaid means or “referred” by another site. Being the opposite of paid traffic, this type of traffic comes to a site without a referral from another site, but from a result in a search engine instead. Although websites do link to each other and provide visitors to your site, organic traffic is considered to be the visitors that land there through the result of a search online through a search engine. Search engine optimization will help your site rank higher organically, so that you can get more organic “free” traffic.
