What does 'organic traffic' refer to?

Organic traffic specifically refers to visitors who arrive at a website through unpaid search results. This means that these visitors clicked on links to the site that appeared in search engine results pages (SERPs) without any payment involved for the placement of those links. The websites that rank well in search results, typically due to strong SEO practices, generate organic traffic by providing relevant and valuable content that aligns with the search queries of users.

In contrast, other types of traffic mentioned in the options emphasize paid avenues or different referral sources. For instance, visitors coming from paid advertisements represent a different category altogether, where payment is made to promote visibility. Social media traffic indicates referral visitors from platforms like Facebook or Twitter, which while important, do not fall under the category of organic search results. Finally, direct URL entries involve users who type the website's address directly into their browser rather than discovering it through a search engine, which is also distinct from organic traffic. Thus, the option that encompasses the essence of organic traffic accurately is visitors arriving from unpaid search results.
