Organic traffic refers to visitors who arrive at a website via unpaid search results. This means they click on search results that are relevant to them. “Organic” refers to the natural, unpaid visibility in search results. Organic visibility and the resulting traffic can be specifically improved through search engine optimization (SEO).
In web analytics tools, organic traffic is reported as a separate channel distinct from other sources, such as traffic from people who type the URL directly into their browser, paid traffic from ads, or traffic from social media.
