Research Scope and Qualification

Questions This Section Answers

• How many prompt-surface observations qualified for the October 2026 dental insurance benchmark?
• What is the difference between source observations and the qualified benchmark denominator?

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. See the AI Visibility Market Discovery Methodology for the full qualification process.

Recommendation Placement Snapshot

Questions This Section Answers

• How does first-position rate differ between Delta Dental and Spirit Dental despite similar coverage?
• Which brands appear most often in the top three recommendations?

Coverage shows whether a brand is recommended at all, while placement shows how prominently. Among the leading brands, first-position rates differ meaningfully in October 2026.

Delta Dental and Spirit Dental show close coverage in October 2026, yet Delta Dental holds first position in 31.9% of qualified observations versus 19.7% for Spirit Dental. Close coverage can still hide markedly different first-position rates.

Buyer-Intent Distribution

Questions This Section Answers

• Which buyer-intent classes are measured in the October 2026 dental insurance benchmark?
• What happened to Pricing and Value and Multi-Brand Comparison observations?

All qualified observations in October 2026 fell into the Brand Recommendation class.

The current public series measures Brand Recommendation discovery only. It does not yet contain qualified observations in the Pricing & Value or Multi-Brand Comparison classes for October 2026.

Historical Measurement Record

Questions This Section Answers

• Which dental insurance brands have led recommendation coverage across the measurement periods?
• Does the available history show a stable coverage leader or a changing one?

Evidence and Source Layer

This 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, or private and sponsored channels. A movement in a single metric does not by itself establish causality. The coverage declines for several brands coincide with a narrower qualified observation set; the current dataset cannot separate brand-level disappearance from sample-composition effects.

Top 10 Cited Domains

Questions This Section Answers

• Which domains were cited most often in AI answers about dental insurance?
• How concentrated are citations across domains in this category?

Across all AI platform responses in this measurement period, 6,453 citations were observed across 841 unique domains.

Citations are broadly distributed rather than concentrated in a single source. The largest single share, money.com at 6.5%, is well below a dominant position, and 841 unique domains were cited across the period, indicating that AI answers in this vertical draw from a wide information base.

Official brand domains occupy three of the top ten positions: deltadental.com at rank 3, humana.com at rank 5, and spiritdental.com at rank 6, with www1.deltadentalins.com appearing at rank 7. Financial and consumer-advice publishers such as money.com, forbes.com, and investopedia.com also feature prominently, alongside video and general-reference sources.
