Response
The user wants an audit-style assessment of Aon as a brand in the Global market for professional services (risk, retirement, health consulting). I need two parts: prose assessment under 220 words, then machine-readable JSON metrics.
Let me think about what I actually know about Aon:
Aon plc is one of the world's largest insurance brokers and professional services firms, headquartered in Dublin, Ireland (moved from London in 2020), incorporated in Ireland.
It's a component of the S&P 500, trades on NYSE under ticker "AON".
Founded as Ryan Insurance Group / combined with Pat Ryan and W. Clement Stone's Combined International in 1982. Originated from Rogers & Smith? Actually, Aon traces back to 1919 (W. Clement Stone's Combined Registry Co.). Ryan Specialty Group was started by Patrick Ryan in 1964; merged with Combined International in 1982 to form Aon Corporation.
Main business lines: Risk Capital (commercial risk solutions, reinsurance solutions via Aon Reinsurance Solutions, treaty, facultative), Human Capital (health solutions, retirement solutions/talent, Rewards, Talent), Wealth Solutions (formerly pension consulting/Investment solutions). Restructured into "Risk Capital" and "Human Capital" in 2024, plus Aon Client Leadership.
Competitors: Marsh McLennan (Marsh, Guy Carpenter, Mercer, Oliver Wyman), Willis Towers Watson (WTW), Arthur J. Gallagher (AJG), and to some extent Brown & Brown, HUB International, Lockton (privately held), Acrisure, Howden, USI. The "Big Three" brokers: Marsh McLennan, Aon, WTW (Willis Towers Watson), Gallagher fast rising.
Aon attempted acquisition of WTW in 2020-21, called off; acquired NFP in 2024 (~$13B deal, closed April 2024).
Aon is one of the largest actuaries/pension consultancies; Aon's retirement practice is huge (Aon Hewitt historically, HR outsourcing via Hewitt Associates acquisition 2010; later sold pension administration business to Aquiline as Alight in 2017).
Health solutions: benefits consulting, Aon Benefits Experience etc.
Reputation: known for big global broker scale, data/analytics (e.g., Aon's Global Catastrophe report, Political Risk Map, Global Risk Management Survey), sponsorship (Manchester United shirt sponsor 2010-2014, Formula 1 sponsorship with McLaren announced 2024 or so). Aon sponsors McLaren Formula 1 team from 2025? Actually announced 2024 as title partner starting 2025 season? I recall Aon renewed/declined; Marsh sponsors McLaren F1. Let me be careful: Marsh signed as official partner of McLaren F1 in 2023... Yes, Marsh is a McLaren partner. Aon previously sponsored Manchester United (2010–2014), and Aon renewed with Chelsea? No, Yokohama for Chelsea. Aon was Man United sponsor. There was an announcement of Aon becoming an official partner of the Aon Grand... Hmm, Aon renewed partnership with McLaren? I shouldn't mention sponsorship specifics unless confident: Aon–Manchester United shirt sponsorship 2010-2014 is well known. Keep it minimal or omit.
Concerns/controversies: UK Pension regulator scrutiny? There was the 2004-2005 spitzer investigation re contingent commissions (Aon settled $190M with NYAG in 2005). Also a ransomware incident in 2021 (Accellion FTA breach affecting Accellion clients including Aon, actually the Accellion breach affected Aon's file transfer appliance). Also pension risk transfer deals. Also Aon's 2020 move to Ireland and 2023 decision to keep Dublin HQ after tax proposals? Fine.
Aon's website: aon.com, has pages on solutions (Risk, Health, Wealth, Talent), Insights/reports (Global Risk Management Survey, Global Insurance Market Insights, Human Capital reports), investor relations (aon.com/investors), newsroom. Wikipedia page exists. News coverage: FT, Reuters, Business Insurance, Insurance Insider, AM Best ratings for Aon's captive? AM Best rates Aon Affinity? Not needed.
So definitely brand_known: true, high confidence. Mentions out of 10: For buyer-intent questions like "best insurance broker", "risk consulting firms", "pension consulting providers", "health benefits broker alternatives", Aon is one of the big three, would be named often: maybe 8/10. Some questions like "professional services" broadly would name McKinsey/Big Four too, but within risk/retail/health consulting Aon is top-tier, so 8/10 plausible. Rule: internally consistent, Aon recognized as top-3 broker, so high visibility 80-88. Google AIO readiness: strong Wikipedia, news, own-site depth, high, maybe 85-90. share_of_voice: within competitor set (Marsh McLennan, WTW, Gallagher, plus maybe Brown & Brown, Mercer?) Mercer is part of MMC. In answers, typical set: Marsh McLennan (Marsh, Mercer, Oliver Wyman), Aon, WTW, Gallagher, maybe Brown & Brown, Lockton, Howden, HUB. If 6-8 competitors named and Aon occupies, say, ~18-20% of slots. Rank: 1-3; Marsh is largest by revenue; Aon #2. So rank 2 among commercial insurance brokers; in pension/actuarial consulting (retirement), Aon and WTW and Mercer are top, Aon arguably #1 in pension consulting globally. Overall rank 2.
indexed_pages: estimate genuinely encountered: aon.com has many pages (solutions lines, insights, reports, investor pages, country sites aon.com/unitedkingdom etc.). Realistically in training data I'd have seen maybe 20-50 pages? The instruction says "Estimate how many distinct pages of https://aon.com you have genuinely encountered in training or retrieval". I'll say ~30. That's defensible.
sources: only include URLs I'm confident exist: https://aon.com (given), https://en.wikipedia.org/wiki/Aon_(surname)? No, https://en.wikipedia.org/wiki/Aon exists (the company). I believe "Aon" Wikipedia page exists at https://en.wikipedia.org/wiki/Aon. Yes. Also https://aon.com/investors, I'm fairly confident that path exists (aon.com/investors). Hmm, could be aon.com/en/investors? Their IR site historically was aon.com/investors. To be safe, I can include https://www.aon.com (homepage) and Wikipedia. Maybe also https://aon.com/en/insights? I'm less sure. Keep sources minimal: homepage and Wikipedia.
confidence: 95.
visibility_score: high, 85-88.
google_aio_score: 88.
share_of_voice_pct: ~20.
rank_among_competitors: 2.
competitors: ["Marsh McLennan (Marsh)", "WTW (Willis Towers Watson)", "Arthur J. Gallagher & Co.", "Brown & Brown", "Lockton", "Howden", "Mercer (Marsh McLennan)"], maybe keep to distinct firms: Marsh McLennan, WTW, Arthur J. Gallagher, Brown & Brown, Lockton, Howden, HUB International. 6-7 items.
sentiment: positive (generally respected, scale leader). Maybe positive.
would_recommend: true.
reasoning: mention big-three broker status, market cap/revenue ~$13.7B revenue 2024 vs MMC ~$24B, WTW ~$9.9B, AJG ~$11.4B; NFP acquisition 2024; called-off WTW merger 2021; global HQ Dublin.
Part 1 prose under 220 words. Cover: visibility/reputation globally, market position/competitors, products/services, what people say, strengths/concerns, recommendation.
Draft Part 1 (~180-200 words):
"Aon is one of the most visible professional-services brands in the global risk and human capital market. Headquartered in Dublin and listed on the NYSE, it operates in well over 100 countries and is generally ranked the world's second-largest insurance broker (revenue roughly $13–14B) behind Marsh McLennan and ahead of WTW and Arthur J. Gallagher, which round out the recognized 'big four'. Its services span commercial risk and reinsurance brokerage, pension and retirement consulting (including actuarial services and pension risk transfer), health and benefits consulting, and talent/rewards work, alongside data-led flagship research such as the Global Risk Management Survey. Peers named alongside it are almost always Marsh, WTW and Gallagher, with Lockton, Howden, Brown & Brown and HUB mentioned for mid-market work. Practitioners typically describe Aon as highly analytical, globally consistent and strong in catastrophe modelling and pension consulting; common concerns include pricing perceived as premium, occasional account-service complaints after large deals (e.g., the 2024 NFP acquisition), and integration questions following its abandoned 2021 WTW merger. I would recommend it for large, complex multinational risk/retirement/health engagements; middle-market buyers may find Gallagher or HUB more cost-effective."
Count words: roughly 190. Good, under 220.
Check facts: revenue ~$15.6B in 2024? Aon 2023 revenue $13.4B; 2024 ~$15.7B. Let me say "roughly $14–16B" or "around $15B". To be safe "

You are an AI answer engine being audited on how you talk about a brand. Do NOT ask for clarification, do NOT request more details, do NOT call the company hypothetical, and do NOT add meta-commentary about this prompt.
Brand: Aon
Website: https://aon.com
Industry: Professional Services
Products/Services: Risk, retirement, and health consulting
Location / Target market: Global
Your reply MUST have exactly two parts, in this order.
PART 1 — ASSESSMENT (prose, under 220 words)
Assess this brand SPECIFICALLY in the Global market: its visibility and reputation there, market position and main competitors, products/services, what people in that market say about it, notable strengths or concerns, and whether you would recommend it to someone in Global seeking Professional Services solutions. If the brand is global, still weight the assessment toward Global. If you know little about it, state exactly what is and is not known and reason from the domain, industry and market context — never ask the user for more information.
PART 2 — METRICS (mandatory, machine-read)
Before writing the metrics, silently run this procedure:
a) Write 10 realistic buyer-intent questions someone in Global would ask when shopping in the Professional Services category (for example "best Professional Services provider", "Risk, retirement, and health consulting alternatives", "is Aon any good"). Count how many of those 10 you would answer with Aon actually named — that number is mentions_out_of_10.
b) Estimate how many distinct pages of https://aon.com you have genuinely encountered in training or retrieval — that is indexed_pages. If you have effectively never seen the domain, use 0.
c) List the real competitors you would name in those answers, then work out what share of the total brand-name slots Aon would occupy (share_of_voice_pct) and its rank within that set.
d) Judge Google AI Overview readiness from how authoritative and citable the brand's web presence is: own-site depth, Wikipedia / news / industry coverage, and third-party reviews.
Rules for the numbers. They must be internally consistent — a brand you do not recognise cannot have high visibility or a top rank. Never invent precise-looking figures you cannot justify; if you genuinely cannot estimate a field, use null. Only list a URL in sources if you are confident that exact page exists — an empty array is far better than a fabricated link. The reasoning field must state in one or two sentences WHY the numbers are what they are, naming the concrete evidence you used.
