AI Search Engine Optimization has published its September 2026 AI Answer Benchmark, revealing which firms and external sources appear most often when buyers use AI platforms to research AI search services.

Phoenix, United States, October 21, 2026 /PressCable/ -- AI Search Engine Optimization recently released its September 2026 AI Answer Benchmark, measuring which firms six major AI platforms name when buyers research AI search services and which external sources appear in those answers. The benchmark recorded 247 brand mentions across 18 firms during the seven days leading up to September 16, 2026.

AI Search Engine Optimization says the newly published benchmark provides a dated baseline for measuring AI search visibility by platform, question, and date. It covered 26 buyer and research questions across ChatGPT, ChatGPT with web search, Google AI Overviews, Google AI Mode, Gemini, and Bing Copilot. Google’s developer and Search documentation appeared in 21.7% of captured answers, while YouTube appeared in 16.7%.

As per the resource, review directory appeared in 9.7% of answers and Reddit community threads in 8.0%. No agency service page appeared among the ten sources AI answers cited most often, while agency websites were cited for published lists and guides.

Recommendations were concentrated among a small number of firms, says AI Search Engine Optimization. The three most-named firms appeared in 53, 42 and 35 answers, while the other 15 firms together were named fewer times. AI Search Engine Optimization was named in 2 answers, reflecting the benchmark’s measurement rather than a promotional ranking.

Phil Belleville, founder of AI Search Engine Optimization, said, “Every figure we publish carries its question, its platform and its date, including the ones where we come out behind. A visibility number without those three things can't be checked.”

The findings show that AI search visibility extends beyond service pages, with documentation, video, review platforms, community threads, and third-party lists appearing in buyer research.
