Recommendation Coverage Movement

Largest Increase: TaxAudit

TaxAudit rose 10.7 percentage points in valid recommendation coverage, from 1.2% in July 2026 to 11.9% in August 2026. Its top-three rate climbed 5.0 points from 0.0% to 5.0%, and its rank-one rate rose 5.0 points from 0.0% to 5.0%, both beyond normal month-to-month variation. Presence rate held steady at 56.4% in August 2026 versus 57.0% in July 2026.

Category Leader: TaxAudit

TaxAudit led the category with 11.9% valid recommendation coverage in August 2026, up from 1.2% in July 2026. It also held the highest presence rate at 56.4% in August 2026, and was the only brand whose top-three and rank-one rates both reached 5.0%.

Recommendation Placement Snapshot

Coverage alone does not show how prominently a brand is recommended. Placement rates show whether a brand appears at the top of the list or just within it.

Similar coverage levels can still hide different first-position rates. Tax Crisis Institute reached 6.9% coverage in August 2026, yet its rank-one rate of 5.0% was identical to TaxAudit's, despite TaxAudit holding nearly double the coverage.

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 & 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.
