ChatGPT advertising pays 6.6 times more than Google search advertising For every $1 spent on ChatGPT advertising, companies generate $0.52 in revenue, compared to $3.40 in Google search advertising, according to a study by the Frankfurt School of Finance and Management and the Vienna University of Economics. Ad conversion on ChatGPT was 0.37% compared to 1.17% for Google. Among 102 OpenAI advertisers, 82% did not record a single purchase through neural network advertising. At the same time, free recommendations from the chatbot itself work better than paid placements.
