What is organic search traffic? First of all, organic SEO is nothing like what you are probably imagining. Any preconceived notions you may have about “organic” need to be set aside for the moment in order to understand this internet-related concept. Organic search traffic is what happens when someone searches something on a search engine. A list of pages pops up and the user selects which one they want to visit. This is organic search traffic. It consists primarily of keywords and links.
