LANY, a digital marketing company, analyzed 9.4 million access logs from the B2B comparison site IT Trend. The study found that ChatGPT's AI crawler accesses user reviews at roughly 17 times the rate of human users. The crawler also heavily accesses product detail pages and articles. Pre-training crawlers lean more on reviews, while real-time crawlers reference articles and product details. LANY says the data highlights the growing importance of having information on third-party sites for AI visibility.
The analysis covers 9.4 million access logs from IT Trend, a B2B comparison site, over a year from December 2024 to November 2025. The logs include both human behavior from Google Analytics 4 and ChatGPT crawler records. The key finding: ChatGPT's pre-training crawler hits review pages at a rate 17 times higher than human users. This suggests that the AI relies heavily on user reviews for learning. The crawler also accesses product detail pages and articles, but less than reviews. Pre-training crawlers favor reviews, while real-time generation crawlers reference articles and product details more. LANY, the digital marketing firm behind the study, argues that companies should place information on comparison sites to be read by AI, but warns that the quality of the information matters. The report was published on LANY's owned media site.
