The honest caveat first
OpenAI does not publish a ranking algorithm for recommendations, and neither do Anthropic or Google. What follows is not insider knowledge. It is the pattern visible when you study which companies AI systems actually name, across categories, over time. The pattern is stable enough to plan around.
The four signals that keep showing up
1. Entity clarity
Recommended companies are easy to define. The model can state what they do, who they serve, and what category they belong to, because the public web says it the same way everywhere. Ambiguous companies get skipped, not because they are worse, but because the model cannot confidently describe them.
2. Independent citations
Companies that appear in third-party sources, editorial articles, industry roundups, interviews, and reference pages, get named more often than companies whose only description is their own website. Self-description is a claim. Coverage is corroboration. The mechanics are laid out in AI Answer Visibility.
3. Consistency over time
A burst of mentions from one campaign fades. A steady record across quarters keeps a company in the training data and the retrieval results. This is why reputation signals behave like compound interest rather than advertising.
4. Topical depth
Being mentioned once next to a topic is trivia. Being repeatedly associated with a specific question, "endpoint security," "revenue operations," "sleep medicine", is what makes a model reach for your name when that question is asked. That is topical authority.
What clearly is not the mechanism
- Payment. There is no ad unit inside the recommendation. You cannot buy the answer directly.
- Website size. Small companies with clean entities and real coverage outrank sprawling sites with neither.
- Keyword stuffing. Models synthesize meaning; they do not count repetitions on your homepage.
What to do with this
Treat the four signals as a checklist. Fix the entity first, because it multiplies everything else. Then build citations through placements and interviews. Then sustain it. The step-by-step version is in How to Get Mentioned by ChatGPT, and the diagnostic version, why a specific company is missing, is in Why Your Company Doesn't Appear in ChatGPT.
