Research Scope and Qualification

Questions This Section Answers

• How many raw prompt-surface observations became qualified benchmark observations?
• What distinguishes the public benchmark denominator from the raw collection universe?

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. Link AI Visibility Market Discovery Methodology.

Current Brand Standings

Questions This Section Answers

• Which brands appear most often in valid AI recommendation shortlists?
• How do presence, coverage, top-three, and rank-one rates differ across the tracked PEO and HR brands?

How to Read the Standings

Presence rate is the share of qualified observations where the brand is mentioned in an answer. Valid recommendation coverage is the share of qualified observations where the brand appears in a valid recommendation shortlist. Top-three rate is the share of qualified observations where the brand appears among the top three recommended options. Rank-one rate is the share where the brand is the first recommendation. Net sentiment describes benchmark framing of mentions, not customer sentiment, and is the share of positive minus negative mentions among all mentions.

Recommendation Placement Snapshot

Questions This Section Answers

• Which brand is most often recommended first, even when coverage is close?
• How did top-three and rank-one placement change for Rippling PEO, Gusto, and BambooHR?

Coverage alone does not show how prominently a brand is recommended. In October 2026, Rippling PEO led coverage at 63.8%, while Gusto placed first in 24.5% of qualified observations versus 15.8% for Rippling PEO.

Close coverage can still hide different first-position rates. Gusto led first-position placement in both months, while Rippling PEO raised its rank-one rate to 15.8% in October 2026 from 9.8% in July 2026, and BambooHR moved up to 11.3% from 9.3%.

Buyer-Intent Distribution

Questions This Section Answers

• Which buyer-intent classes contain qualified observations in the current series?
• What does the absence of pricing and multi-brand comparison observations mean for the benchmark?

All qualified observations in July 2026 and October 2026 fell into the Brand Recommendation class, which measures AI responses that recommend one or more named brands.

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

• Who has led qualified recommendation coverage across each measurement period?
• Which brand has shown the largest coverage movement throughout the series?

This is an evergreen benchmark URL. New measurements are added to the same report.

Evidence and Source Layer

Questions This Section Answers

• What evidence is retained for each prompt-level observation?
• How should source presence be interpreted relative to recommendation outcomes?

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.

Top 10 Cited Domains

Questions This Section Answers

• Which domains were cited most often across AI platform responses?
• How concentrated are citations across the observed domains, and which brand-owned domains appear?

Across all AI platform responses in this measurement period, 6,263 citations were observed linking to 1,131 unique domains.

Citations are broadly distributed rather than concentrated, with the top ten domains accounting for roughly 27% of the 6,263 total citations across 1,131 unique domains. Two tracked brands' own domains appear in the top ten: rippling.com at rank five and adp.com at rank nine. The mix skews toward a blend of publishing and review sources, including general news and business outlets such as forbes.com and business.com, HR trade publishers such as peoplemanagingpeople.com, review platforms such as g2.com and technologyadvice.com, and user-generated sources such as youtube.com and reddit.com.
