Testing a product that doesn't yet exist — a 3D render or a mocked main image with a placeholder working title — against real competitor listings in a panel tool like Helium 10 Audience Tool (Shopper Image-Preference Survey) to gauge whether shoppers would choose it over entrenched incumbents.
Used before committing resources to a new SKU, brand extension, or category entry: if testers wouldn't pick the fake product over real competitors at a viable price, the concept is disqualified before tooling or inventory spend. A failure mode surfaces here that a live click-through A/B test can't reveal: the price needed to make the fake product competitive against an incumbent with far more reviews may be low enough to break the entrant's unit economics — the test exposes that before money is spent, not after.
Distinct from Competitor-Benchmarked Split Testing (vs. Self-Only Comparison) (which pits an existing listing's main image against competitors) and Search-Results-Page Mockup Testing (which varies price/rating/reviews on a real listing) — here the product itself is hypothetical.
