Recommendation Placement Snapshot

Coverage alone does not show how prominently a brand is recommended. Among the leading brands, placement patterns differ notably from coverage rankings.

Brookdale Senior Living converted a larger share of its coverage into first-position placements in August 2026 than either Atria Senior Living or Sunrise Senior Living, despite all three brands having similar top-three rates in July 2026.

Buyer-Intent Distribution

All qualified observations in both July 2026 and August 2026 fell into the Brand Recommendation class, which captures discovery and consideration queries.

The current public series measures Brand Recommendation discovery only and does not yet contain qualified observations in the Pricing & 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.
