Only 14.4% of responses triggered a web search, with an average of 1.6 queries per search. The study found that ChatGPT prioritizes official brand sites for factual questions—like prices or specs—citing them in 84.4% of such cases. For comparison questions, citations dropped to 68.3%, with more reliance on third-party sites like Reddit or Wikipedia, though their share has declined sharply since March 2026. Partner publications (e.g., licensed content) now account for 12.5% of citations, up from 7.5% earlier in the year. The data also highlights growing demand for terms like *price* (up 47% month-over-month) and *reviews*, while definitions and generic queries fell. Ahrefs advises brands to optimize for original content—product facts, research, or reviews—rather than summaries, as ChatGPT increasingly favors primary sources.","keyPoints":["ChatGPT searches the web in 14.4% of free, logged-out responses, averaging 1.6 queries per search","Official brand sites dominate citations for factual questions (84.4%), while comparison queries rely more on third-party sites (68.3%)","Partner publications now make up 12.5% of ChatGPT citations, up from 7.5% in March 2026"],"whyItMatters":"Brands must prioritize original content—like product specs, reviews, or research—over summaries to appear in ChatGPT’s citations.
