If your brand ranks well in DeepSeek, Doubao, or Kimi, that result tells you nothing about how you appear in ChatGPT or Gemini, because the two ecosystems index different sources, trust different signals, and cite in different languages [nanjingmarketinggroup.com]. Chinese AI platforms are largely built on a domestic web of walled-garden platforms, while ChatGPT and Gemini draw primarily from the open English-language web [i-click.com]. A supplier can be the top-cited answer for a category on DeepSeek and not exist at all when a buyer in Germany or the US asks ChatGPT the same question. That is not a bug in either system. It is two separate information ecosystems that happen to look similar from the outside because they both produce a conversational answer.
