nothing — everything on the page is also in your markup

hasVariant an agent sees unrelated products.It is not an audit and not a judgement of the business — it is a 8-page sample taken on a stated date, scored on a published rubric with no model judgement in it. Nothing here predicts whether any assistant will recommend you; for most answer engines that is decided by a private merchant feed we cannot see. If a number here is wrong, tell us and it goes in the public corrections log.
This scorecard is a sample — eight product pages, drawn at random from a published seed. It tells you where Guitar Center stands, not which SKUs are costing you. We’ll run a real sample of the whole catalog through the same extractor and send back the fields that are missing, by product.
Everything above stays free either way — the rubric, the sampled pages, the dataset, and every other company’s scorecard.
