Build and review language-specific prompt panels before combining multilingual visibility results. A translated sentence can preserve grammar while changing how local buyers describe their problem, which businesses are relevant or what an answer recommends.
Preserve the research question
Record language, market, audience and the actual buyer decision for every prompt. Language and location are separate variables: English-language shoppers in India and the United Kingdom may face different product availability.
OpenAI's evaluation guidance explicitly includes non-English and multilingual input variability. The workflow here is an editorial recommendation for panel design, not a provider claim about equal performance across languages.
Review translations for intent
Use a competent local reviewer to check constraints, category vocabulary, brand spelling and natural phrasing. Back-translation can reveal issues, but it does not establish that buyers would ask the resulting question.
Illustrative example: translating “accounting software for sole traders” literally may miss the locally used business term. Changing the term can improve intent fidelity while making the texts less literally similar. Record the reason.
Keep branded recall prompts apart from unbranded discovery. Adding the brand to make a translated question clearer contaminates an unbranded test.
Measure each panel separately
- Freeze exact texts and their language-specific IDs.
- Use declared provider and model configurations.
- Record valid-answer coverage for every language.
- Review entity aliases with local context.
- Retain examples of both presence and absence.
- Mark unresolved translation or classification cases.
A provider failure in one language should not count as a brand absence. An unfamiliar local spelling should not automatically be discarded as an unrelated entity.
Decide whether aggregation is useful
If the business needs one summary, state the language weights and their business rationale. Do not imply that equal weighting measures the market's actual demand. Without verified demand data, it is a planning choice.
Show the language breakdown beside the aggregate. Otherwise, improvement in a large or easy-to-measure panel can hide a deterioration in another market.
Changes to translation or local aliases are measurement changes. Version them and explain their effect before describing a trend as a customer-perception change.
Read the prompt panel guide for baseline rules. Next, review the covered provider surfaces and pilot a locally reviewed panel before treating a single translated score as international performance.
