Research Scope and Qualification

The public benchmark is narrower than the raw collection universe by design. Brand-level percentages use the qualified observations as the public denominator, not the raw collection.

Recommendation Placement Snapshot

Questions This Section Answers

• How does The Hartford's rank-one rate compare with its top-three rate?
• Why can two brands with similar coverage have very different first-position rates?

Coverage alone does not show how prominently a brand is recommended. The Hartford was ranked first in more than a third of qualified observations (35.1%) in October 2026. Progressive Commercial's rank-one rate (13.5%) was less than half its top-three rate (29.4%).

Close coverage can still hide very different first-position rates: Nationwide and Simply Business ended October 2026 within about 25 points of each other on coverage, but Nationwide was the first recommendation in 6.0% of observations against Simply Business at 1.1%.

Buyer-Intent Distribution

All 282 qualified observations in October 2026 fell into the brand recommendation class, where the AI response names or recommends one or more specific brands.

The current public series measures brand-recommendation discovery and does not yet contain qualified observations in the pricing and 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 or sales attribution
• Every possible AI response a system could produce
• Organic-search ranking positions
• Social media mention volume
• Private or sponsored distribution channels
• Causality from a metric movement alone

Top 10 Cited Domains

Questions This Section Answers

• Which domains were cited most often across AI platform responses in October 2026?
• How much do the leading ten domains account for out of all observed citations?
• Which source types dominate the citation layer in this vertical?

Across all AI platform responses in October 2026, 7,596 citations were observed across 981 unique domains.

Citations are moderately concentrated at the top: the leading ten domains account for roughly a third of all observed citations, with no single source exceeding 6%. Two tracked brands' own domains appear in the top 10, progressivecommercial.com at rank 2 and thehartford.com at rank 3, both cited across all six canonical surface families. The remainder of the list skews toward third-party comparison and review properties, alongside general platforms and a business news outlet, suggesting that aggregator and editorial sources carry meaningful weight in how AI surfaces assemble answers in this vertical.
