Research Scope and Qualification

The public benchmark reports on qualified observations only, after removing off-topic and non-substantive prompt-surface responses. July 2026 produced 315 qualified observations; August 2026 produced 384. Within those totals, 109 qualified observations in July 2026 and 121 in August 2026 were recommendation-shaped answers, and 201 in July 2026 and 240 in August 2026 contained a valid, attributable recommendation shortlist. Brand-level percentages throughout this report use qualified observations as the denominator, not the raw collection volume.

AI Market Discovery Methodology

Current Brand Standings

How to Read the Standings

Presence rate is the share of qualified observations where the brand is mentioned in the AI response. Valid recommendation coverage is the share of qualified observations where the brand appears in a clearly attributable recommendation shortlist. Top-three rate is the share where the brand appears among the top three recommended options. Rank-one rate is the share where the brand is the single first recommendation. Net sentiment score runs from -1 (all negative mentions) to +1 (all positive mentions).

Recommendation Placement Snapshot

Coverage alone does not show how prominently a brand is recommended. Among the leading brands, Northwest Registered Agent and ZenBusiness also led on placement.

Close coverage rates can still hide different first-position rates, as seen with ZenBusiness: its rank-one rate of 20.3% trailed Northwest Registered Agent's 26.0% despite similar top-three positioning.

Buyer-Intent Distribution

All qualified observations in both months fell into the Brand Recommendation class.

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

Historical Measurement Record

Evidence and Source Layer

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, attributable sales, every possible AI response, organic-search ranking, social mention volume, private or sponsored channels, or causality from a metric movement alone. Movement in any single metric should not be read as a causal signal.
