A study analyzing 120 B2B buyer questions across five AI engines (ChatGPT, Perplexity, Gemini, Claude, and Google AI Overviews) revealed that official vendor websites are cited far less often than third-party sources like comparison articles and community threads. Wikipedia was a notable exception, cited 36 times. The research also found that AI engine responses can vary significantly, with approximately 15% of answers changing when the same question is re-asked, and that Gemini's cited URLs are often opaque redirects rather than direct sources. The findings suggest that businesses should focus on securing citations on trusted third-party sites to improve their visibility in AI-generated answers. AI
