About these numbers
Sample: 10 real AI answers to 10 prompts across 5 sampled niches, Oct 27, 2026 – Oct 28, 2026. Demand: Google Keyword Planner, Oct 2025 – Sep 2026.
- Product categories: brand visibility and cited sources come from Google AI Mode and AI Overview answers only. ChatGPT brand mentions and ChatGPT citations are left out for now: the first ChatGPT run of these prompts went through an API path instead of the real ChatGPT app. The real-app monthly run of 27-Nov-2026 replaces it. ChatGPT already counts for native shopping cards and ads.
- Shopping captures are still pending for about 9% of answers; shopping figures cover the captures already closed.
- Spain: Google AI Mode rarely shows native catalogs (about 12% of short searches).
- Demand: Google Keyword Planner monthly searches, Oct-2025 to Sep-2026 (12-month average). AI asks per month are estimated from Google volume × the share of commercial searches each AI engine already answers.
- CPCs for Spain and the United States are converted from MXN with the European Central Bank reference rate of 2026-10-28.
- Product categories: every sampled niche gets the same two prompts in every country, a short product search (Google AI Mode) and a buying question (ChatGPT). Native shopping figures count only real product cards (price, store or catalog link), never products read from the answer text.
- Answers are refreshed monthly; the next refresh is around 27-Nov-2026.
