Research Scope and Qualification

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

Research stage	Jul 2026	Sep 2026	What it represents
Source prompt-surface observations	800	800	Total prompts collected across AI surfaces
Unique questions	533	577	Distinct questions after de-duplication
Brand / competitor mentions	800	800	Prompts naming at least one brand or competitor
Relevant observations	682	753	Prompts relevant to the prenatal vitamins category
Irrelevant observations	118	47	Prompts outside the category scope
Qualified benchmark observations	621	652	Public denominator after all qualification

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

How to Read the Standings

Presence rate: share of qualified observations where the brand is mentioned at all.
Valid recommendation coverage: share of qualified observations where the brand is explicitly recommended.
Top-three rate: share of qualified observations where the brand appears among the top three recommendations.
Rank-one rate: share of qualified observations where the brand is the first recommendation.
Net sentiment: positive minus negative mentions, divided by total mentions, describing benchmark framing rather than customer sentiment.

Largest Decline: Garden of Life

Garden of Life's valid recommendation coverage fell to 32.1% in September 2026 from 48.6% in July 2026, a decline beyond normal month-to-month variation. Recommendation coverage measured zero in August 2026, and the September 2026 figure marks a partial recovery, with the brand present in 37.0% of observations that month. The September figure is a partial recovery, not a return to baseline strength. One A Day likewise fell to 22.6% in September 2026 from 29.1% in July 2026, beyond normal variation, after recommendation coverage also measured zero in August 2026.

Category Leader: Ritual

Ritual led the category with 80.8% valid recommendation coverage in September 2026, effectively unchanged from 80.3% in July 2026 on a baseline-to-current basis. Ritual's monthly coverage dipped to 75.0% in August 2026 before recovering to 80.8% in September 2026, a month-over-month gain beyond normal variation. The leader position changed after Nature Made moved to 78.5% in September 2026 from 81.3% in July 2026. Ritual's top-three rate moved to 47.4% in September 2026 from 53.3% in July 2026, while its rank-one rate held near 14.7% in September 2026.

Recommendation Placement Snapshot

Brand	Sep 2026 top-three rate	Sep 2026 rank-one rate	Jul 2026 top-three rate	Jul 2026 rank-one rate
Nature Made	55.7%	27.6%	54.6%	28.5%
Ritual	47.4%	14.7%	53.3%	14.8%
Perelel	19.3%	8.3%	11.4%	3.2%

Coverage and placement can diverge. Nature Made and Ritual held similar coverage in September 2026, but Nature Made's rank-one rate of 27.6% was nearly double Ritual's 14.7%, indicating a much stronger first-choice position despite Ritual's slightly higher overall coverage.

Buyer-Intent Distribution

In both months, all qualified observations fell into the Brand Recommendation class.

Buyer-intent class	Jul 2026	Sep 2026

Evidence and Source Layer

This 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, not automatically proof that the source caused the recommendation.

Scope Boundaries

This public benchmark does not measure market share, attributable sales, every possible AI response, organic-search ranking, social mention volume, private or sponsored channels, or causality from a metric movement alone. Single-month movements should not be treated as trends without confirmation from subsequent measurement periods.
