After analyzing “billions of pieces” of content, content marketing firm BrightEdge claims organic search is the primary driver of website traffic to business sites, while social barely generates a blip on the traffic radar.

The BrightEdge study found organic search drives 51 percent of all visitors to B2B and B2C websites, trumping all other non-organic search channels, including paid search (10%) and social (5%).

BrightEdge went beyond breaking down traffic sources to examine how traffic is distributed by industry.

According to the study, organic search traffic accounted for 73 percent of all traffic to business services site, more than a 20 percent jump from the 51 percent when evaluating organic search across all sites.
