This document discusses a study that found that almost 60% of people have no idea which links on Google search results pages are paid ads. Only 6% realize they are ads and click on them, while 35% know they are ads but do not click. The ability to recognize ads has remained relatively static since 2017 and may depend on a person's age. The document recommends using both SEO and paid search (Google Ads) together for the best chance of driving traffic.
