Can You Use AI to Advertise a Professional Practice Within the Rules?

Yes, if a qualified person owns every claim. AI can draft adverts, headlines and posts for a solicitors', accountants' or advisers' practice, but the rules apply to what is published, not to who wrote it. The practice must make sure each statement is accurate, not misleading, properly labelled and approved before it goes out.

The problem is not that AI writes badly. It writes fluently, and fluent copy is the dangerous kind in a regulated profession. A model will happily produce "the best conveyancing team", "guaranteed returns" or "we save clients thousands", none of which you can prove. So the useful question is where AI sits in the process, and the answer is: at the drafting step, behind a fixed brief, in front of a compliance check that a person completes.

The rules sit on the advert, whoever wrote it

Different professions use different rulebooks, but they converge on a short list of ideas. I name the main ones below as examples. Check the current text for your own regulator, since rules and guidance are revised.

• Solicitors. The SRA Code of Conduct for Solicitors groups client information and publicity together (paragraphs 8.6 to 8.11). Publicity about the practice must be accurate and not misleading, including what it says about charges, and solicitors must not make unsolicited approaches to members of the public, other than current or former clients, to advertise their services. The separate SRA Transparency Rules require a firm's website to publish its complaints procedure and, for listed services such as residential conveyancing and estate administration, cost information.
• Accountants. ICAEW's marketing helpsheet says firms must not bring the profession into disrepute when marketing, citing its Code of Ethics, and that adverts must comply with the law and the advertising standards body's requirements. It then lists what firms must not do: disparage other practices, make claims of size or superiority they cannot substantiate, exaggerate their services, qualifications or experience, make unsubstantiated comparisons, or promote services to the point of harassing a potential client. Other accountancy bodies have their own equivalents.
• Financial advisers and lenders. The FCA says all financial promotions must be clear, fair and not misleading whatever the media type, and it links product-specific rules for areas such as retail investments and consumer credit. Who can approve a promotion is a separate rule with its own conditions.
• State bars for lawyers. State rules are generally modelled on ABA Model Rule 7.1: a lawyer shall not make a false or misleading communication about the lawyer or the lawyer's services, and a communication is misleading if it materially misstates fact or law or leaves out a fact needed to stop the whole from misleading. The comment to the rule as states have adopted it warns that truthfully reported past results can still mislead if they suggest the same outcome for other clients. States add their own rules on specialist claims, testimonials, disclaimers and solicitation, so check your state's current text.

What these share: the practice must not mislead, must present facts it can support, must identify itself properly, and cannot hand its responsibility to a tool or an agency. A regulator reading a complaint will ask who approved the advert, what evidence supported each claim, and what the practice did to check. "The AI wrote it" is not an answer to any of those. For the wider firm picture, the AI governance checklist for advice firms sets out the policy side.

What AI is good for in advert drafting, and what it must never decide

Split the work into the parts that carry regulatory weight and the parts that do not.

The rule behind the table: AI shapes and words what you already know to be true. It does not supply the facts, make the comparison or choose the claim.

Main worked example: a four-partner accountancy practice

Say a four-partner accountancy practice wants to promote its small-business year-end service. The marketing lead writes a fact sheet in ten lines: services included, a fixed fee range the partners have approved ("from $950 for a sole trader, from $1,600 for a small company, depending on records"), turnaround time ("accounts delivered within four weeks of receiving complete records"), who does the work, and the regulatory statement the firm uses. She then asks an assistant to draft three versions of a web page intro and a LinkedIn post.

Draft a 120-word web page intro and a 60-word LinkedIn post for
our small-business year-end accounts service.

Use ONLY the facts below. Do not add claims about savings, ranking,
awards, years of experience or client results. Do not compare us with
other firms. Do not promise outcomes. Use plain, calm language.
Include the fee line exactly as written.

Facts:
- Service: year-end accounts and tax return for sole traders and
  small companies
- Fees: from $950 for a sole trader, from $1,600 for a small company,
  depending on the state of the records
- Turnaround: accounts delivered within four weeks of receiving
  complete records
- Work done by a qualified accountant and reviewed by a partner
- Call to action: book a 20-minute call

An illustrative first draft comes back with this line in it: "We are the stress-free way to handle your accounts, trusted by hundreds of small businesses and saving owners thousands every year." The compliance check, covered next, finds four problems. "Stress-free" is a vague promise, "trusted by hundreds" is a number the firm has not supplied, "saving owners thousands" is an unsupported outcome claim, and "the" way implies superiority over others. The corrected line reads: "We prepare year-end accounts and tax returns for sole traders and small companies, from $950, delivered within four weeks of receiving complete records." The edit removed adjectives and kept facts. The change is typical: most of a compliance edit is deletion.

The compliance check, as a form a person completes

Put this check in a shared document or your project tool. It takes about ten minutes per advert for someone who knows the rules. The point is that it is written, repeatable and leaves a record.

1. Every factual claim has a source on file. For each claim in the advert, name where the evidence is: the fee schedule, the staff list, the engagement terms.
2. No outcome promises. No guaranteed results, no "will save", "will win", "will reduce", unless the practice can prove and lawfully make the statement.
3. No unsupported superlatives or comparisons. "Best", "leading", "number one", "cheapest", "most experienced", and any named competitor comparison, need documented support or come out. Some codes go further: ICAEW's helpsheet gives "we provide a better service than [named firm]" as unacceptable even if it is objectively true, while "we pride ourselves on the service we provide" is fine.
4. Prices and fees are exact and complete. The wording says what the fee covers, what it excludes, and any variable element. Any required price transparency details are present.
5. Required identifiers are present. Firm name, regulatory status, registration or licence details and any required disclaimers, taken from the approved block.
6. Testimonials and cases are real and approved. Written client consent on file, and the text matches the approved version.
7. Specialist or expertise claims match accreditation. Only claim a specialism the regulator or the body permits you to describe that way.
8. Risk balance. For anything touching investments, credit or tax planning, the advert gives a fair picture, and risk warnings are as prominent as benefits where rules require.
9. Audience and channel fit. The advert does not target vulnerable people unfairly, and the platform's own advertising rules for regulated services are met. For a solicitors' practice, an AI outreach tool that writes and sends personalised cold messages to members of the public is an unsolicited approach of the kind the SRA Code rules out, except to current or former clients.
10. Sign-off. Name, date and version of the approver, and the final text stored.

A model can help with the first pass of this check. Give it the advert and the list, and ask it to mark every claim that needs evidence. Its list is a prompt for the human reviewer, not a replacement. Say the reviewer reads the AI's flags and finds it caught three of four problems and missed one: "within four weeks" had no evidence that the firm met that target in busy season. A person catches that because they know the firm.

A prompt for the claim-spotting pass

You are checking a draft advert for a regulated accountancy practice.
List every statement that is a factual claim, a comparison, a promise
of outcome, a superlative, a testimonial or a price. For each, say
what evidence the practice would need to hold on file. Do not rewrite
the advert and do not say whether it is compliant.

Four more situations from a typical quarter

A solicitors' firm turns a guide into social posts

A small firm publishes a guide to what happens when a tenant stops paying. The marketing assistant asks an AI tool for five posts from the guide. The posts must stay inside what the guide says, because a post is a short, context-free version of advice and tends to overstate. Rule for the firm: each post carries a pointer to the guide and a line that the content is general information. The reviewer deletes one draft that implied "you can always evict within weeks". See the tutorial on AI marketing for small law firms for the content-and-reviews side.

An adviser's investment-themed post

An independent adviser asks an assistant for a post about saving into a pension. The draft includes "markets always recover". That is a performance-flavoured statement with no balance, and it fails the risk-balance test. The compliance lead rewrites it as a general educational post with no recommendation, a plain risk statement and a link to the firm's approved page. If the advert counts as a financial promotion under the adviser's rules, the approval route matters more than the wording.

The "reviews" page

A practice asks AI to turn client feedback into a testimonials page. Two of the quotes were paraphrased by the tool and the clients never saw the new wording. The practice pulls the page, goes back to each client with the exact text, and keeps their replies. New rule: AI may fix typos in an approved testimonial, never paraphrase one.

An ad agency that uses AI

A firm hires an outside agency that drafts ads with AI and posts them directly. The firm remains responsible for the content. The fix is contractual and practical: the agency sends every ad for written approval before it runs, and the firm's check list is part of the brief. Ask the agency which tools it uses and what it does with the firm's information. The tutorial on AI website articles for law firms is a useful model for the brief.

Before and after: three rewrites a reviewer would make

Seeing the edits is the quickest way to train a team. These are illustrative lines of the kind AI produces, each with the compliance version beside it.

Notice what the second row does. The reviewed line does not become vague. It becomes true, and says who the service is for. A good compliance edit usually makes the advert clearer, which is why the check does not have to cost you conversions.

Images, voices and video in adverts

Text is the easy case. Practices now also generate headshots, illustrations, voiceovers and short videos with AI, and each brings a distinct risk. An AI-generated "partner" photo on a team page misleads visitors about who they will deal with, and it is hard to defend as anything else. A synthetic voiceover reading a testimonial implies a real client spoke. A stock-style illustration of a happy family on a family-law page is fine if it is plainly decorative, but an image that implies a real result ("a client at their new home") is a claim.

A workable rule: real people for real people. Use genuine staff photos for team pages, real recordings for testimonials, and clearly illustrative graphics for concepts. Where your regulator, the platform or the law requires AI-generated media to be labelled, label it, and when in doubt label it anyway. The guide to labelling AI-generated images and video covers the mechanics on the main social platforms.

Paid ads, targeting and platform rules

An advert for a regulated service passes through two sets of rules: your regulator's and the platform's. Several ad platforms restrict or add certification steps for financial services, and some limit targeting options on certain categories. Read the platform's current policy for your service before you build a campaign, and keep a copy of the version you relied on. AI makes it easy to generate fifty ad variants. The practice should treat each variant as a separate advert for compliance purposes, which is why a short list of approved claims, rather than free-form generation, keeps the volume manageable.

A sensible pattern: the compliance owner approves a library of claims, headlines and call-to-action lines, and AI recombines only those. Variants built from approved parts need a quicker check than new copy, and the log shows which approved parts went into each ad. If a regulator later asks about a variant, you can show the parts and the approval.

Website copy and AI-search answers

Your website's service pages also feed answers in AI search tools. A vague or overstated sentence on a page can be quoted without its context. Write pages so that every sentence still reads accurately on its own: name the service, the audience and any limit in the same sentence. That is good for compliance and for being quoted correctly. Avoid pages that rely on a disclaimer three screens down to correct a headline claim.

A filled-in claims library, as a starting point

Approved claims (reviewed [date], owner: [name])
Service: year-end accounts, sole traders and small companies
- "Prepared by a qualified accountant and reviewed by a partner." (staff register)
- "Fees from $950 for a sole trader." (fee schedule v4)
- "Accounts delivered within four weeks of complete records." (service standard, target only)
Not approved: savings claims, rankings, "leading", "trusted by" numbers
Required block: firm name, regulatory status line, registration detail

Keep the library short. A long one becomes hard to review, and a short one lets you say with confidence what the practice is prepared to stand behind.

Confidentiality and data when you brief the tool

Adverts rarely need client information. Use public facts, your own fee schedule and anonymised, composite examples only. If you do use a case study, the client's consent for the publication has to come first, and the text should still avoid anything that could identify them by detail. When choosing an AI tool, prefer a business plan whose terms say your content is not used to train models by default. The general point is covered in the tutorial on whether financial advisers can use ChatGPT.

A short written policy for adverts that involve AI

A one-page policy turns the above into a habit. Illustrative wording you can adapt:

Advertising and AI: practice policy
1. AI may draft marketing copy from a fact sheet approved by [name].
2. AI never supplies facts, prices, results, rankings or testimonials.
3. Every advert, post or page goes through the ten-point check.
4. [Name] approves the final text. The approved version is stored.
5. No client-identifiable information goes into an AI tool.
6. Agencies and freelancers follow the same steps and send drafts
   for approval before publication.
7. We review this policy every six months and after any regulator
   guidance on AI or advertising.

Measuring whether the process works

Track three things for a quarter. How many drafts needed changes at the compliance check, and what kind. How long each advert takes from brief to approval. And whether anything has been corrected or withdrawn after publication. If corrections after publication stay at zero and the check time falls, the process is working. If the compliance lead edits the same claim every time, put that exclusion in the prompt. A prompt that says "do not claim savings" is cheaper than deleting the sentence fifty times.

A word on speed. Say the practice previously spent two hours on each page between drafting, rewriting and approval. With a fact sheet, a standing prompt and the ten-point check, the drafting falls to twenty minutes and the compliance check to ten, leaving about half an hour a page. The time saved is real only if the check does not shrink, and that is the discipline to protect.

Where it goes wrong, and how it shows

• Invented specifics. The tool adds a number, an award or a client story. It shows up as any detail not in your fact sheet. Search each draft for digits and names and tick them against the sheet.
• Copied phrasing. The tool echoes a competitor's slogan or a regulator's wording. Run a quick search on any distinctive phrase.
• Tone drift. Over time the copy becomes more promotional than the profession's rules allow. Compare new copy with an approved example every month.
• Approval skipped under deadline. The advert goes live "just this once". Make the platform's scheduling tool require the approver's name before anything is queued.
• Old rules. The prompt and the check list stay unchanged while the regulator updates its guidance. Put a six-month review date on both.

For firms that want a wider view, the AI compliance checklist for small businesses covers the questions beyond advertising. If you want help setting up the fact sheet, the prompts and the check for your own practice, my AI implementation consultation covers that mapping. Nothing here is legal advice; take your regulator's current rules and your compliance lead's view as the final word.

Questions from regulated practices about AI adverts

Does using AI change who is responsible for an advert?

No. The practice and the named professional remain responsible for every statement, whoever or whatever drafted it. Regulators judge the published advert, not the tool. Treat AI output as a junior's first draft that a person must read, verify and approve.

Do I have to say an advert was written with AI?

There is no general rule I could verify that requires it for text adverts, but a rule may apply to synthetic images, voices or testimonials. Check your regulator and the ad platform. Never use AI to invent a client or a quote.

Can AI write client testimonials or case studies?

Not invented ones. A testimonial must be real, current and used with consent. AI may help tidy wording a client has approved, but the client must agree to the final text, and the practice should keep that approval.

Can I paste client details into an AI tool to write a case study?

Not without thinking about confidentiality and consent. Anonymise heavily, use a business plan with suitable data terms, and get the client's written agreement before publishing anything identifiable.

Who should sign off AI-drafted adverts?

Someone with the authority and knowledge to say a claim is true and compliant: usually a partner, compliance officer or the person your regulator holds responsible for marketing. Name them in your process, and keep a record.
