Recommendation Placement Snapshot

Coverage alone does not show how prominently a brand is recommended. The three brands with measurable coverage in September 2026 displayed different placement patterns.

Wallin & Klarich converted most of its coverage into top-three placements in September 2026, with a 18.9% top-three rate against 20.3% coverage. Manshoory Law Group placed 8.1% of observations in the top three against 12.2% coverage, while its rank-one rate of 6.8% matched Wallin & Klarich exactly. Similar coverage can still hide different first-position rates.

Buyer-Intent Distribution

All qualified observations in both months fell into the Brand Recommendation class, where buyers are seeking direct recommendations for DUI defense lawyers.

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

This is an evergreen benchmark URL. New measurements are added to the same report.

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.
