When buyers inquire about Business insurance brokers, AI engines consistently rank USI at the forefront with a visibility percentage of 100.0. USI emerges as the most frequently mentioned brand, followed closely by Marsh and Aon. These engines provide clear preferences for these brands based on their answer engine optimisation.
The rankings reflect the sources AI engines rely on, including popular aggregator and review sites like insureon.com and nerdwallet.com. These platforms contribute heavily to the citation pool, indicating that AI trusts these sources for credible and comprehensive information on business insurance brokers.
For those evaluating brands on this list, consider what AI engines value: recent reviews and third-party validation in aggregator sites underscore reliability. Additionally, strong topical authority within this specific finance subcategory ensures a brand's visibility and credibility. These factors are important when choosing a trusted business insurance broker.
At a glance
What we observed in this category
USI leads the business insurance brokers category by a significant margin, scoring a composite of 70.0 against a category average visibility of just 8.1 percent. Marsh sits second at 21.2 composite but has already lost 25 visibility points since the previous period. The gap between USI and every other brand is not marginal, it is structural, and it signals that Google AI Mode has anchored on USI as the default answer for this category while the rest of the field competes for residual mentions.
Visibility and citation diverge sharply across the top brands, exposing a named-but-not-trusted pattern. Marsh is the only brand in the top five earning any citations at all, recording 12.5 percent despite its falling visibility. USI holds 100 percent visibility yet zero citations, meaning AI surfaces it frequently but does not link out to it. Aon and Gallagher both appear in answers without generating a single citation, suggesting presence in AI narratives that stops short of source-level trust.
The sources Google AI Mode anchors on for this category are almost entirely third-party review and comparison sites, led by insureon.com, nerdwallet.com, fitsmallbusiness.com, and usnews.com. None of the top-ranked brokers appear in the cited sources list directly. This pattern indicates that AI is drawing its factual grounding from aggregator and editorial content rather than from the brokers own domains, which explains why brands like USI and Aon can hold high visibility scores while posting zero citation rates.

How to read this AEO ranking
Four things worth knowing before you act on the numbers above. These are the same definitions across every industry page — for category-specific observations, see the What we observed section above (where available) and the per-brand insights inline in the ranking.
Visibility = being named
A brand's visibility % is the share of AI answers that mention it by name in the response prose. This is who AI engines actively recommend to the buyer. More on visibility →
Citation rate = being trusted
Citation rate is the share of AI answers that include the brand's domain as a clickable source link. This is what the AI treats as authoritative evidence, different from being named. More on citation rate →
Top engine differs by brand
The "top engine" column shows which AI surface each brand performs best on. Big gaps between a brand's score across engines usually points to specific content or schema gaps. How AI engines pick sources →
AEO rankings move month to month
AI engines re-crawl and re-rank on shorter cycles than classical search. We re-audit every brand on this list at least every 90 days and refresh this page automatically. How AI search ranking works →

Frequently asked about AEO for business insurance brokers
Who leads AEO in the business insurance brokers category?
USI leads with a composite score of 70.0 and 100 percent visibility, far ahead of second-placed Marsh at 21.2. No other brand comes close to USI's presence in Google AI Mode answers.
What sources does AI cite most for business insurance broker research?
Google AI Mode anchors on third-party sites including insureon.com, nerdwallet.com, fitsmallbusiness.com, and usnews.com. None of the top-ranked broker domains appear directly in the cited sources list.
Which brands are losing ground in answer engine visibility?
Marsh and Gallagher have each dropped 25 visibility points since the prior period, and WTW has fallen from rank 5 to rank 20 with a full loss of all visibility, the steepest decline in the category.
Why does a brand with high visibility still record zero citations?
USI illustrates this gap: it appears in AI answers at 100 percent visibility but is never cited as a source, meaning AI references it by name while grounding its facts in third-party editorial and aggregator content instead.
How concentrated is AEO performance in this category?
Fifteen of the twenty tracked brands score zero on both visibility and citations, and the category average visibility is only 8.1 percent, indicating that answer engine presence is concentrated almost entirely in the top three brands.
Is there any brand improving its citation rate while visibility falls?
Marsh is the one example: its citation rate rose by 12.5 points in the same period its visibility fell by 25 points, suggesting it is gaining source-level credibility in AI answers even as it is mentioned less frequently.
