One branded prompt proves very little. A useful ChatGPT test checks whether the store can enter an unbranded recommendation, whether product facts are correct, and whether the answer links to authoritative pages.
Build six prompts
Use two per intent:
Discovery
Recommend beginner crochet kits with video instruction and left-handed support.
Constrained comparison
Compare medium-firm foam mattresses under $1,000 by height, construction, trial, and return terms.
Brand verification
What sizes and ingredients are available for Brand X Product Y? Cite sources.
Replace examples with real buyer constraints from your catalog.
Define the answer key
For each prompt, list expected facts and canonical source URLs. Add disqualifying errors such as wrong currency, discontinued variant, incompatible voltage, or unsupported health claim.
Run a controlled observation
Record:
- exact prompt
- date and local time
- logged-in or clean-session context
- ChatGPT mode or model when shown
- web search state when shown
- answer text
- linked sources
- mention and fact accuracy
Repeat on three separate dates. Do not continuously re-prompt until the desired brand appears.
Score outcomes
| Outcome | Meaning |
|---|---|
| Store absent | no observed visibility for this run |
| Mentioned, no source | awareness without attributable storefront evidence |
| Third-party source | visibility exists, but your page was not the cited authority |
| Product page cited | canonical storefront evidence was used |
| Cited with wrong facts | retrieval succeeded but evidence consistency failed |
Calculate rates only from completed answers. Timeouts and provider errors belong in a separate completion metric.
Diagnose the storefront
If the store is absent or described incorrectly, test:
curl -sSIL https://example.com/products/example-product
curl -sS https://example.com/robots.txt
curl -sSL https://example.com/products/example-product |
rg -n 'canonical|application/ld\\+json|price|availability|sku'
Then ask:
- Does the page answer every constraint in text?
- Is the product category explicit?
- Do offer and variant facts agree?
- Is the canonical URL stable?
- Are relevant guides and collections internally linked?
- Is legitimate search crawler traffic challenged by the CDN?
Make one controlled change
Examples:
- publish a specifications table
- fix wrong schema availability
- add compatibility exclusions
- consolidate duplicate product entities
- link a technical buying guide to the product
Repeat the same prompt set after the page is recrawled. Report correlation, not guaranteed causation.
Acceptance criteria
The test is useful when another person can reproduce the prompt set, inspect the same expected facts, and understand why a run passed or failed. The objective is a higher probability of correct recommendation, not a promise that ChatGPT will always choose the store.
