Recommendation Placement Snapshot

Questions This Section Answers

• Which brands appear most often in top-three and first-position recommendations?
• Can a brand with lower coverage still record a higher rank-one rate than the category leader?

Coverage alone does not show how prominently a brand is recommended. Placement rates reveal where brands sit within recommendation lists.

Close coverage can still hide different first-position rates. LightStream recorded a 10.4% rank-one rate in October 2026 despite lower overall coverage than Capital One, whose rank-one rate was 9.6%.

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

Questions This Section Answers

• How did the coverage leader change across the four monthly measurements?
• Are the four months of data enough to establish a trend?

New measurements are added to the same report.

Four monthly measurements are not yet enough to treat leadership changes as a trend.

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.
• It does not measure attributable sales.
• It does not capture every possible AI response.
• It does not measure organic-search ranking.
• It does not measure social mention volume.
• It does not measure private or sponsored channels.
• A metric movement alone does not establish causality.

Top 10 Cited Domains

Questions This Section Answers

• Which domains are cited most often across AI responses about auto refinance loans?
• How concentrated are citations among the top domains, and do any brand-owned domains appear?

Across all AI platform responses in October 2026, 6,944 citations were observed across 690 unique domains.
