Research Scope and Qualification

The public benchmark is narrower than the raw collection universe by design.

Brand-level percentages use the qualified observations as the public denominator, not the raw collection. For full methodology, see AI Visibility Market Discovery Methodology.

Recommendation Placement Snapshot

Questions This Section Answers

• How did top-three and rank-one rates differ among the leading pet supplement brands?
• Why can close coverage still hide different first-position rates?

Coverage alone does not show how prominently a brand is recommended. The leading brands show distinct placement patterns.

Close coverage can still hide different first-position rates. Zesty Paws holds a 17.1-point coverage lead over VetriScience (FoodScience LLC), yet its rank-one rate in October 2026 is 30.1% against VetriScience's 18.9%, a narrower separation than the coverage gap implies.

Buyer-Intent Distribution

Questions This Section Answers

• Which buyer-intent classes were represented in the qualified observations?
• What has the benchmark not yet measured across pricing and comparison intent?

All qualified observations in each month fell into the Brand Recommendation class.

The current public series measures brand recommendation discovery only and does not yet contain qualified observations in the pricing and value or multi-brand comparison classes.

Historical Measurement Record

Evidence and Source Layer

Questions This Section Answers

• What data does each prompt-level observation retain?
• Does a cited source in an AI answer prove it caused the recommendation?

The benchmark is built from prompt-level observations that retain the query, AI/search surface, answer, brand outcome, recommendation placement, sentiment, and, where exposed, citations or attributable evidence sources. Source presence is evidence about the information environment. It is not automatically proof that the source caused the recommendation.

Scope Boundaries

This public benchmark does not measure:

• Market share or attributable sales outcomes.
• Every possible AI response or surface.
• Organic-search ranking positions.
• Social mention volume or sentiment outside AI answer surfaces.
• Private or sponsored channels.
• Causality from any single metric movement alone.

Top 10 Cited Domains

Questions This Section Answers

• Which domains received the most citations in AI answers about pet health supplements?
• How concentrated were citations across the 1,220 unique domains?
• Which source types—retail, veterinary, or community—appear most in this vertical's AI answers?

Across all AI platform responses in this measurement period, 6,688 citations were observed spanning 1,220 unique domains.

Citations are broadly distributed rather than concentrated: the top 10 domains account for a combined 32.9% share across 1,220 unique domains. Two tracked brand domains appear in the top 10: zestypaws.com at rank 6 and vetriscience.com at rank 10, both cited across all six canonical surface families. Retail and marketplace sources (amazon.com, chewy.com, petco.com) sit alongside veterinary and informational sources (petmd.com, akc.org) and community or video platforms (reddit.com, youtube.com), suggesting AI answers in this vertical draw on a mix of commerce, expert, and peer sources.
