Each question was asked once to each assistant on 2026-10-21. "2 of 5" means the business was recommended in 2 of the 5 answers that assistant gave. An answer that failed is left out of the count. When Google shows no AI Overview for a question, nobody is named there. Assistants change their answers between asks, so a small difference is not a ranking.
We list only businesses an assistant recommended. Being named in an answer is not an endorsement by Goppa, and not being listed here says nothing about a business.
