AEO for professional services firms

Updated 17 October 2026 · AEO Services · Every figure on this page links to the study it came from

The short answer

For accountants, lawyers, financial advisers, engineers and architects, AEO is mostly about being visible and consistent in the places an AI engine can use to check that a professional is real and reputable: official registers, professional-body directories, review profiles and independent roundups. Almost every Australian profession has them — CPA Australia's Find a CPA, CA ANZ's Find a CA, the Tax Practitioners Board register, ASIC's Financial Advisers Register, the law societies' directories, Engineers Australia's National Engineering Register — and several are opt-in. The constraint is the rulebook. Queensland limits personal-injury advertising to name, contact details and area of practice; ASIC's RG 234 covers advertising of financial advice; health advertising cannot use clinical testimonials. Good AEO works inside those rules, not around them.

Registers and professional directories are the cheapest high-trust signals you have, and several only list you if you opt in.
45% of US consumers used ChatGPT or similar tools for local business recommendations in early 2026, up from 6% a year earlier. 21% of Australians say they got financial advice from an AI tool in the past year.
Anything you publish to be quoted is still advertising: RG 234, the solicitors' conduct rules, Queensland's PIPA s 66 and Ahpra's testimonial ban all apply.
Reviews must be genuine. The ACCC says incentives must not depend on a positive review and must be disclosed.

How people are using AI to choose a professional

Choosing an accountant, a lawyer or an adviser is a high-trust, high-consideration decision, which is exactly the kind of question people now put to an assistant: “who’s a good small-business accountant near me”, “do I need a lawyer for this”, “is this adviser any good”. The data is still thin and mostly from the US, so treat it as direction, not size.

BrightLocal’s 2026 survey of US consumers found 45% had used ChatGPT or a similar tool for local business recommendations, up from 6% the year before, making AI the third most-used source after Google and Facebook.
A 2026 US study by a legal-marketing agency found 41.9% of consumers would use ChatGPT to research a lawyer, up from 28.1%, while Google fell from 86.7% to 71.9%.
In Australia, Great Southern Bank found 21% of people said they had received financial advice from ChatGPT or similar tools in the previous 12 months (38% of Gen Z), though 69% still valued human advisers more.

We could not find Australian data on how people use AI to find an accountant or a lawyer specifically. If someone shows you a confident number for that, ask where it came from.

Where an engine can check that you are real

AI engines recommend professionals they can verify. In professional services, the verification layer already exists, maintained by regulators and professional bodies, and it is cheap to get right.

Profession	Public registers and directories	Worth knowing
Accountants	CPA Australia’s Find a CPA; CA ANZ’s Find a CA; the Tax Practitioners Board register	Find a CPA and Find a CA are opt-in: public-practice members are listed only if they select it. The TPB register also shows breaches and sanctions on the public record
Financial advisers	ASIC’s Financial Advisers Register on Moneysmart	Shows where an adviser has worked, qualifications, professional memberships and what they can advise on
Lawyers	Law Society of NSW Register of Solicitors and Solicitor Referral Service; Law Institute of Victoria’s Find Your Lawyer Referral; Queensland Law Society’s Find a solicitor	The NSW referral service matches people to up to three of about 1,200 registered firms; the LIV service refers up to three firms with a free first interview of up to 30 minutes; the QLS directory lists full members with an unrestricted practising certificate
Engineers	Engineers Australia’s National Engineering Register	Publicly searchable by name, area of engineering and location
Architects	State registration boards, e.g. the NSW Architects Registration Board	“Architect” is a protected title; the register is the authoritative check

Listings matter more than the usual “earned media” advice suggests. In Yext’s analysis of 6.8 million AI citations, listings were 42% of what engines cited and websites 44%; in finance, 48.2% of citations came from brand-owned websites. That study is vendor research and did not cover law or accounting, but the direction is clear: for professional services, getting the registers, directories and your own practice pages complete and consistent is not housekeeping, it is the work.

The rulebook

Every profession on that list has advertising rules, and content written to be quoted by an AI engine is still advertising. This is a summary, not legal advice.

Solicitors. Under the Australian Solicitors’ Conduct Rules, advertising must not be false, misleading or deceptive, offensive, or prohibited by law, and must not imply specialist accreditation the solicitor does not hold.
Queensland personal injury. The Personal Injuries Proceedings Act 2002 limits advertising to name, contact details and area of practice, published by an allowable method — which includes a directory “published or maintained independently” of the practitioner. A firm’s own website may explain the law of negligence and its terms. The maximum penalty is 300 penalty units, and in May 2026 a Gold Coast principal was publicly reprimanded over website wording including “Free consultation – No win no fee”. New South Wales removed its blanket personal-injury advertising ban when the Uniform Law replaced the old regulation, though scheme-specific rules may still apply.
Financial services. ASIC’s RG 234, reissued in June 2026, is written for promoters of financial advice services as well as products and credit, and for publishers of their advertising.
Health practitioners. Under the National Law, testimonials cannot be used to advertise regulated health services; reviews about non-clinical matters such as customer service are allowed.
Everyone. The ACCC says it is illegal to create fake reviews or arrange for others to, that review incentives must apply whether the review is positive or negative and be clearly disclosed, and that suppressing genuine negative reviews can mislead. HealthEngine was ordered to pay $2.9 million.

The consequence for AEO is that the playbook leans on facts rather than claims: complete registers, consistent naming, genuine reviews, and plain-English explanations of the questions clients ask, with sources. That happens to be what engines quote anyway. The Princeton GEO research found citing sources and adding statistics raised visibility by 30–40%; it found nothing for superlatives.

What AEO looks like for a professional firm, in order

Registers and directories first. Opt in where listing is optional, and make the firm name, address, practice areas and contact details identical everywhere. This takes hours, not months.
Practitioner and firm identity. Engines verify people as well as firms, especially advisers and lawyers. Practitioner pages on your site should match the registers exactly and link to them.
Reviews, collected properly. Ask every client, respond to every review, follow the ACCC rules. In one large study, brands with no active review profile appeared in 1% of AI answers against 75.3% for brands actively collecting and responding.
Answer-first explainers for the questions clients ask before they call — what a service costs, how long it takes, what to bring — written to your profession’s rules and signed off by you.
Independent coverage. Professional-body features, trade and local publications, and the “best firms” roundups that appear in your citation map.
Measure with a prompt set phrased the way clients ask, including suburb and city: see the Sydney, Melbourne and Brisbane pages for what we found locally.

Questions people actually ask

Can a Queensland personal-injury law firm do AEO at all?

Yes, within narrow limits. The Personal Injuries Proceedings Act 2002 (Qld) restricts personal-injury advertising to a statement of the practitioner's or firm's name, contact details and area of practice, published by an allowable method — and a directory or database published independently of the practitioner is one of those methods. A firm's own website may explain the law of negligence and the firm's terms. So the AEO work for such a firm is mostly accurate directory presence and factual, non-promotional explanation, never claims such as "no win, no fee", which the Act gives as an example of a breach. Get your own legal advice on any specific copy.

Do AI engines actually use the TPB or ASIC registers?

We cannot confirm which engine reads which register; none of the engines publish their source lists. What we can say is that these are public, authoritative records of exactly the facts an engine needs to verify a professional, and that listings in general are a large share of what engines cite. The audit measures it directly: if a register appears in the citation map for your category, it is a priority.

Can we ask clients for reviews?

Yes, and you should. The ACCC's rules are that reviews must be genuine, that any incentive must apply whether the review is positive or negative and be clearly disclosed, and that you must not suppress or remove genuine negative reviews. Health practitioners have an extra rule: testimonials about clinical aspects of care cannot be used in advertising.

Who signs off the content?

You do, or your compliance lead or practice manager. We write to the rules of your profession and flag anything we think is near a line, but we are not your lawyers or your compliance function, and nothing is published without your approval.

Is AEO worth it for a small practice?

Often, because one client is worth a lot. A practice where a new client is worth $5,000 or more in gross margin needs very few extra clients a year to cover an audit, and the first jobs — registers, directories, review profile, consistent naming — are cheap. The break-even table in our guide to whether AEO is worth it shows the arithmetic.
