Latest answer per business and question before the month ended. | Assistant | Own site or direct vendor | Marketplace | Directory | Nowhere useful | Answers | | --- | --- | --- | --- | --- | --- | | ChatGPT | **70%** | 16% | 0% | 14% | 90 | | Claude | **70%** | 19% | 2% | 9% | 90 | | Gemini | **88%** | 10% | 0% | 2% | 90 | ### Asked the way people ask | Assistant | Own site or direct | Marketplace | Directory | No link | Places | | --- | --- | --- | --- | --- | --- | | ChatGPT | **90%** | 0% | 0% | 10% | 39 | | Claude | **54%** | 6% | 9% | 31% | 35 | | Gemini | **87%** | 0% | 0% | 13% | 39 | Method ## How this page is made Every business of the index's kind with a website of its own is scanned the same way, about once a month, and every scan is kept. This page takes the latest scan of each site before October 2026 ended, so a site fixed in the following month shows up in the following month's page, not here. A past month does not change. The assistant tables use the latest answer per business and question before the month ended.
