Category Leader: NetSuite

Recommendation Placement Snapshot

Coverage alone does not show how prominently a brand is recommended. NetSuite led both top-three and rank-one placement at 21.5% and 8.8% in September 2026.

Similar coverage can hide different first-position rates. SAP Ariba, despite low overall coverage, carried a rank-one rate of 1.2% in September 2026, higher than several brands with greater coverage.

Buyer-Intent Distribution

In September 2026, all qualified observations fell into the Brand Recommendation class.

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

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. It records the change; it does not, by itself, establish why the change occurred.
