Brand-level visibility can hide product-level problems. Hero Products are the flagship items you most care about, and each gets its own dedicated deep-dive prompt, scored individually for how favourably AI describes it when asked specifically.
This matters because a brand can have strong overall visibility while its newest or highest-margin product is described thinly, inaccurately, or not at all. A 0-100 read per hero product shows where the engines talk about your stars positively and substantively versus where they're vague or missing the details that drive a purchase.
It's the difference between "AI knows my brand" and "AI can actually sell my best product", and it points precisely at which product pages and facts need to be clearer and more reachable for the engines to pick up.
