ContextObserved market evidence
Captured ads, advertiser presence, and prompts where ads appeared can show that a theme exists in the market. They do not reveal an advertiser's literal private hint or conversion rate.
Measurement guide
Which Context Hint Is Working?
Keep the theme associated with better qualified business outcomes—after confirming both tests had comparable eligibility and enough opportunity.
Business quality beats delivery volume.
Public captured-ad evidence can help form a hypothesis. Only your own campaign and conversion data can tell you whether that hypothesis produced valuable outcomes.

Know what each signal can prove.
Inferred targeting evidence
Repeated creative and prompt patterns can support a reconstructed context-hint hypothesis. Confidence describes the reconstruction, not campaign success.
Your delivery data
Impressions and reach show that the complete campaign entered relevant opportunities. They do not isolate the causal effect of one sentence.
Your business outcomes
Qualified conversions, revenue, retention, or another downstream metric are the strongest decision signals available to the advertiser.
Worked interpretation
Fewer impressions can still produce the better theme.
Suppose a comparison-intent group receives less delivery than a broad research group but produces more qualified trials and retained customers. The broad theme wins on reach; the comparison theme wins for the business.
