ChatGPT paid traffic delivers less revenue than Google Search in early study
Researchers from Frankfurt School of Finance & Management and the Vienna University of Economics and Business analyzed nearly 10 billion visits to 1,898 ecommerce sites over 60 weeks. They found ChatGPT ad traffic converted at 0.37%, versus 1.17% for Google Search, but the paper remains under review and reflects an early-stage product.
Why it matters: Marketers considering AI-search budgets need to benchmark ChatGPT against established paid search rather than assume comparable performance. The findings may affect channel allocation, bid ceilings, testing priorities and expectations for AI-advertising ROI, while also signalling that the economics could change as the product matures.
