The five numbers
Share of Shelf is the headline, but it is a product of the others, and that is what makes them worth reading separately.
How to read it
The three that matter most form a funnel, and each failure has a different fix. Shopping-Mode Rate — does a shelf appear at all? If this is low, your tracked prompts are not the kind that make AI produce a product list. That is not necessarily a problem: some categories are researched conversationally rather than shopped. But if buyers in your category do ask shopping questions, low shopping-mode rate means your prompt library is not covering how they ask. Presence Rate — when a shelf appears, are you on it? This is the hard gate. A shelf you are absent from cannot be improved by ranking better. Absence usually traces to the product not being discoverable to the AI in the first place — missing from the retail and review sources these answers draw on. Top-Pick Rate and Avg Position — when you are on it, where? Only meaningful once presence is healthy. If you appear on most shelves but sit near the bottom, the problem is comparative: something about how your product is described, priced, or reviewed puts it behind the alternatives.Read Presence Rate before Share of Shelf. A rising Share of Shelf driven purely by competitors dropping off is not the same as one driven by you appearing more often, and only the funnel tells you which happened.
Exploring the shelf
Below the metrics, the explorer breaks the shelf apart. You can filter by AI platform, and by who the product belongs to:- Own — your products
- Tracked competitors — brands in your configured competitor set
- Untracked competitors — everyone else appearing on your shelves
Why a product was surfaced
Where the underlying AI answer explains its reasoning, Cited captures it — the attributes and phrasing that came with the recommendation. This is the most directly actionable part of the surface. Knowing you rank fourth is a score; knowing the three products above you were all described in terms of a specific attribute is a content and merchandising instruction.What it covers
AI Shelf reads the AI platforms that actually produce product shelves. Not every tracked platform does — a shelf requires the answer to render a structured product set, which is a behaviour specific to shopping-oriented surfaces. Product-to-brand attribution is deterministic rather than inferred: a product is matched to your brand or a competitor by rule, not by a model’s guess. Anything that cannot be matched confidently is reported as untracked rather than assigned.Related
