Same questions, same days, different answers. That disagreement is the point: a check that skips an engine is guessing on your behalf.
| Engine | Days asked | Distinct businesses |
|---|---|---|
| Anthropic | 28 | 0 |
| Gemini | 28 | 7 |
| Google SERP | 28 | 17 |
| OpenAI | 28 | 18 |
| Perplexity | 28 | 19 |
Days asked counts the days each engine received the questions. Gemini returned no business names after September 26, so its answered days are fewer than its days asked.
Anthropic answered all 28 days and named zero businesses; it returned buying criteria and directories instead of names. Perplexity named 19 distinct businesses. If your customer asks Perplexity and you're invisible there, the other four engines don't save you.
