Visitors can also fall into the direct category by clicking a link to your site from an email or PDF document, accessing your site from a shortened URL (which is an abbreviated version of your website address), clicking on a link from a secured site to your non-secure site, or clicking on a link to your site from a social media application like Facebook or Twitter. And, there is a chance that accessing your site from an organic search can end up being reported as direct traffic.
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.
