ChatGPT Cites Travel Sources Most: 22.6% in May

ChatGPT cites sources most frequently when answering travel questions, reaching 22.6% in May. This is significantly higher than the average of 6.8% across all topics. Retail answers followed at 13.5%, and sports at 10.7%. Education questions had the lowest citation rate at 4.8%. What's interesting is that the overall rate of ChatGPT citing sources has increased. It climbed from about 1.3% to 6.8% in less than a year. This shows a growing trend in AI models referencing external information. The bottom line is that the type of website cited varies by topic. For example, in travel, reviews and user-generated content make up over half of citations. This matters because it highlights the need for businesses to understand how AI models source information in their specific industry.
