SEO, AEO, and GEO for professional services firms

For professional services firms, SEO, answer engine optimization (AEO), and generative engine optimization (GEO) are one job: making a firm's people, services, fees, and credentials easy for search engines and AI assistants to find, cite, and recommend when businesses and individuals look for an accountant, a tax adviser, or a consultant. It rests on SEO, because assistants that search the web draw their sources from search indexes. For professional services, the research points to four additions: public, checkable facts about services and fees; credentials that a reader can verify; accurate profiles on the marketplaces and local listings that buyers and assistants use; and attribution that asks clients how they found the firm, because many engagements still start with a referral.

Accountants and tax practitioners work under written advertising rules. The AICPA's code says a member in public practice "shall not seek to obtain clients by advertising or other forms of solicitation in a manner that is false, misleading, or deceptive" (opens in a new tab), state boards of accountancy add their own rules, and the Treasury's Circular 230 says a tax practitioner may not use any public communication "containing a false, fraudulent, or coercive statement or claim; or a misleading or deceptive statement or claim" (opens in a new tab). We found no profession-wide advertising code for management consultants in the United States; the FTC's standards for advertising, endorsements, and reviews apply to them as to any business. This page covers both sides: what helps a firm appear in search results and AI answers, and what the rules let it say there.

This page is part of AEO HQ's guides by industry. It covers SEO, AEO, and GEO together, as one practice that AEO HQ calls SEO+. Google's guidance on outside services uses both names for the same work, referring to "AI experiences (sometimes called AEO for 'answer engine optimization' or GEO for 'generative engine optimization')" (opens in a new tab) (official documentation). Facts on this page link to their sources, evidence strength is labeled where it matters, and recommendations are marked as ours. AEO HQ is itself a professional services firm, and much of the evidence on AI buying comes from companies that sell software or marketing services; the text says so each time. The summary of rules is not legal or ethics advice.

Scope and definitions

This page is for partners, marketing staff, and business development teams at U.S. accounting firms, tax practices, bookkeeping firms, and management and technology consultancies, and for the agencies that work for them. It covers unpaid visibility in search results and AI answers, and the pages, profiles, and reviews behind it. It covers accounting and tax in the most detail, because their advertising rules are written down: the AICPA Code of Professional Conduct, updated through September 2026; the Texas State Board of Public Accountancy's advertising rule, as one example of a state board; and Circular 230's rule on solicitation. Law firms have their own page. Financial advisers, broker-dealers, architects, and engineers answer to other regulators and are not covered. Rules were read on 27 September 2026, and other states differ.

• Answer engine. An AI system that answers a question in its own words and names or links its sources, such as ChatGPT, Gemini, Claude, Perplexity, Microsoft Copilot, and Google's AI Overviews and AI Mode.
• Retrieval. The step in which an assistant fetches pages from a search index while it writes an answer.
• AICPA Code of Professional Conduct. The ethics code of the American Institute of CPAs for its members. On the CPA credential itself, it tells members to follow "applicable state accountancy laws and board of accountancy rules and regulations" (opens in a new tab).
• Circular 230. The Treasury regulations, at 31 C.F.R. Part 10, that govern practice before the Internal Revenue Service (IRS). Section 10.30 covers solicitation and applies to a practitioner "with respect to any Internal Revenue Service matter" (opens in a new tab).
• B2B services marketplace. A directory where business buyers compare service firms by profile, reviews, and prices, such as Clutch.
• Individual practitioner. Google's term for "a public-facing professional, typically with their own customer base" (opens in a new tab), who may have a Business Profile of their own.
• Your Money or Your Life (YMYL). Google's term for topics that could significantly affect people's health, financial stability, or safety (opens in a new tab). Its rater guidelines name "YMYL Financial Security: Topics that could damage a person's ability to support themselves and their families" (opens in a new tab) as one type.

How buyers find professional services firms, and where AI fits

Business buyers research service providers with AI more than any other category in one recent survey, but no study measures how often AI decides which accounting firm or consultancy is hired. The evidence is thinner than for software buyers (our assessment), and most of it comes from companies that sell marketing or software. The table gives each finding with its sample.

What an assistant says about a firm's fees. In July 2026, the marketing firm above described asking ChatGPT what a leading accounting firm charges. The answer noted that the firm "does not publish a standard, one-size-fits-all price sheet," then gave hourly rates by staff level anyway; asked whether those prices were based on the firm's actual pricing data, the author answers "No," and writes that unless a firm publishes its prices, "the prices don't reflect your actual fees" (opens in a new tab). This is one example from a firm with a commercial interest. It is consistent with the survey finding above that 27% of AI-using buyers see pricing misstated.

Limits. All of these figures are self-reported or come from vendors' panels, and every publisher sells marketing services or software. The Semrush survey covers business purchases of all kinds, not only professional services. The only buyer study specific to professional services predates AI assistants. No study with a transparent method measures which firms assistants name, or how often. The direction of the evidence is consistent (moderate); the size of AI's role in choosing a firm is unknown.

How assistants find and choose firms

An assistant can answer from what its model learned in training, its parametric knowledge, or it can search the web and write from the pages it retrieves. For questions about firms, four findings matter:

• Assistants that search rely on search indexes. Google says its generative AI features are "rooted in our core Search ranking and quality systems" (opens in a new tab) and that optimizing for them "is optimizing for the search experience, and thus still SEO" (opens in a new tab). OpenAI says ChatGPT search "sometimes partners with other search providers," and it names Microsoft and Shopify (opens in a new tab) (all official documentation).
• Local questions use location and listings. ChatGPT may use an approximate location based on the user's IP address "to provide relevant local results," and may share location with third-party providers of local information "such as nearby business listings" (opens in a new tab). Google says Business Profiles "can help your products and services to be visible in both AI responses and other Google Search results" (opens in a new tab) (official documentation). In a preprint comparing a web-enabled AI engine with Google on local-business queries, the share of cited domains the two had in common was 15.4% for tax preparation, and local overlap was lower than in broader consumer categories (opens in a new tab) (mid-2025). Ranking well in Google's local results therefore does not ensure that an assistant cites the same sources (our reading).
• Assistants lean on third-party sources. In controlled comparisons across several consumer categories, AI search showed "a systematic and overwhelming bias towards Earned media," meaning third-party sources, compared with Google's more balanced mix (opens in a new tab) (preprint; mid-2025; professional services not tested).
• Marketplaces now sit inside the assistant. In April 2026, Clutch, a B2B services marketplace, launched an app inside ChatGPT that surfaces "verified profiles, review highlights, pricing signals, and real client feedback" when a user asks, for example, "Which digital marketing agencies have the best reviews for SaaS companies?" (opens in a new tab) (company announcement). Clutch says users can find the app by searching for "Clutch" in ChatGPT's apps menu (opens in a new tab).

No study found for this page measures which sources AI answers cite for questions about accountants or consultants. Answers also change from one run to the next: when the same prompt was repeated, ChatGPT and Google's AI returned the same list of brands less than once in 100 runs, and Claude only slightly more often (opens in a new tab) (2,961 runs, November–December 2025; industry study; a co-investigator works for a tracking vendor). How ChatGPT, Gemini, Claude, Perplexity, and Copilot find and cite sources describes each assistant's index and crawlers.

The questions buyers and firms ask

Questions buyers ask

The example wording below is illustrative. The evidence column comes from the survey of AI-using B2B professionals above.

What firms ask about SEO, AEO, and AI search

In AEO HQ's keyword data for the United States, pulled on 27 September 2026, no AEO or GEO queries matched professional services. An industry with no matching queries may still have demand that the pull did not capture.

In AEO HQ's query research (Google and Bing suggestions and forum thread titles, 27 September 2026), and in the question headings of an agency's guide for accounting firms, firms' questions fell into the groups below. Many suggestions used "CPA" to mean cost per acquisition ("what is cpa marketing") and "AEO" to mean something else ("what is an aeo in payroll"), so this page spells out "certified public accountant" where it matters and "answer engine optimization."

Local search, marketplaces, and entity signals

Accounting and tax practices that serve local clients meet AI answers through local results and Business Profiles. Firms that sell nationally meet them through their own sites, marketplaces, and publications. For both, the aim is one set of facts that every source repeats.

Google Business Profiles

Firm names carry a second set of rules. The AICPA code says a member shall not practice public accounting "under a firm name that is misleading," and a firm may not call itself "Members of the American Institute of Certified Public Accountants" unless all its CPA owners are members (opens in a new tab). Texas bars the use of "a name that is misleading as to the identity of the individual practicing under such name" (opens in a new tab). The firm name on the Business Profile, the website, and every marketplace profile should be the licensed name (our recommendation).

One set of facts everywhere

An entity is a person or organization that search systems treat as one distinct thing. Keep the firm's name, offices, services, industries served, fee information, and each professional's name and credentials identical on the website, the Business Profile, marketplace profiles, professional directories, and LinkedIn. The reasons are indirect: language models often merge information about different entities that share a name (opens in a new tab) (peer-reviewed), and in lab trials consistent rather than contradictory claims raised a source's odds of being cited first in at least four of six models (opens in a new tab) (peer-reviewed; laboratory setting; the authors work for a marketing software vendor). The marketing firm quoted above found that assistants looking for a firm's prices seem to look first for "any pricing information on the web that is connected to your firm," such as a "Starting at" price listed, probably years ago, on a public directory or certification site (opens in a new tab) (practitioner observation). No study has tested whether consistent facts raise AI recommendations of firms, so treat this as an inference. The entity and brand consistency checklist lists the checks.

Structured data: useful, but not an AI citation lever

Structured data is code that describes a page to search engines. It helps Google identify a firm; the evidence does not show that it earns AI citations.

• Identify the firm. Organization markup on the home page helps Google "disambiguate your organization in search results" (opens in a new tab), and for each office Google asks for the most specific LocalBusiness subtype (opens in a new tab). For an accounting office, that is AccountingService, "Accountancy business," a subtype of FinancialService (opens in a new tab). Schema.org says its general ProfessionalService type "was deprecated due to confusion with Service" (opens in a new tab). Schema.org has no consulting type, so a consultancy's office can use LocalBusiness and its home page Organization (our reading).
• Do not expect stars for your own reviews. If the entity being reviewed controls the reviews about itself, its pages that use LocalBusiness or Organization markup are ineligible for review stars (opens in a new tab) (official documentation).
• Do not sell markup as an AI tactic. In a matched study of 1,885 pages that added structured data, AI Overview citations fell 4.6%, and changes for AI Mode (+2.4%) and ChatGPT (+2.2%) were statistically indistinguishable from zero (opens in a new tab) (vendor study; all pages were already heavily cited). Google says "there's no special schema.org markup you need to add" (opens in a new tab) for its AI features, and it stopped showing FAQ rich results on May 7, 2026 (opens in a new tab).
• Keep hidden fields honest. Google asks site owners to make sure structured data matches the visible text on the page (opens in a new tab). A claim that the rules bar on the page is no safer in a title tag or markup (our reading).

Crawling and indexing

Assistants can cite only pages their crawlers can reach. Sites that block OAI-SearchBot "will not be shown in ChatGPT search answers" (opens in a new tab); blocking Claude-SearchBot may reduce visibility in Claude's search results (opens in a new tab); and PerplexityBot access is controlled by robots.txt (opens in a new tab). Google's AI features can show only pages that are indexed and eligible to appear with a snippet (opens in a new tab) (all official documentation). Keep services, fees, and bios in the HTML the server sends, not only in PDFs or proposal decks: in December 2024, none of the major AI crawlers rendered JavaScript (opens in a new tab) (network measurement).

Which third-party sources carry weight

Buyers and assistants both lean on sources a firm does not control. The evidence here is thinner than for other industries; the table says where it is missing.

What the evidence does not show. No study found for this page measures which sources assistants cite for accounting, tax, or consulting questions, or whether a marketplace listing causes a recommendation. The low citation rate that Similarweb reports for professional services prompts suggests that many answers in this category come without links to check (our reading).

Our recommendations:

1. Publish the facts buyers check on your own site first: services, industries served, fee information, and who does the work.
2. Complete the free profiles next: Google Business Profile for staffed offices, and the marketplaces your buyers use.
3. Ask every client for reviews the same way, within the rules below.
4. Earn mentions honestly. Google says "seeking inauthentic 'mentions' across the web isn't as helpful as it might seem" (opens in a new tab). The evidence on brand mentions has its own guide.

Rules that limit professional services marketing

This section is not legal or ethics advice; check with your state board and counsel. It summarizes the AICPA code, one state board rule, Circular 230, and FTC guidance, as read on 27 September 2026. Rules differ by state and credential, and they change.

AICPA Code of Professional Conduct

The code below is updated for all official releases through September 2026. Citations are to its sections.

State boards: Texas as an example

Texas's rule for licensees, 22 Tex. Admin. Code § 501.82 (last amended effective June 3, 2020), bars communications about professional services that contain "a false, fraudulent, misleading or deceptive statement or claim," and defines such a statement to include one that is "intended or likely to create false or unjustified expectations of favorable results"; that "implies educational or professional attainments or licensing recognition not supported in fact"; that says services can be performed for a stated fee "when this is not the case," or states fees without disclosing "all variables that may reasonably be expected to affect the fees"; that "consists of self-laudatory statements that are not based on verifiable facts"; that "makes untrue comparisons with other accountants"; or that "contains testimonials or endorsements that are not based upon verifiable facts" (opens in a new tab).

The same rule has record-keeping duties. A copy of an electronic or direct mail communication, with a list of recipients, must be kept for at least 36 months, with exceptions such as communications to current clients or ones the recipient invited; broadcasts must be recorded and kept for at least 36 months; and "broadcast" is defined to include transmission over "Internet, cellular, e-mail system or any other electronic means" (opens in a new tab). The rule does not say how these duties apply to web pages or chat assistants; a Texas firm should ask the board (our recommendation). Other states' boards have their own rules.

Circular 230: tax practice

Consultants and every firm: FTC standards

• Comparisons. The FTC evaluates comparative advertising "in the same manner as it evaluates all other advertising techniques," asking "whether or not the advertising has a tendency or capacity to be false or deceptive" (opens in a new tab).
• Employees and agencies. The FTC's guidance on endorsements says that when employees share a company post that could be viewed as promoting its services, "employees endorsing the post should disclose their relationship to the company," (opens in a new tab) and that employees of an ad agency or public relations firm "have a connection to the advertiser, which should be disclosed in all social media posts" (opens in a new tab).
• AI claims. The FTC's chair said its 2024 enforcement actions "make clear that there is no AI exemption from the laws on the books" (opens in a new tab). In November 2024, the FTC announced a proposed settlement with a company that sold AI-powered security scanners to schools and other institutions; the order would prohibit misrepresentations about any material aspect of the products' performance, "including the use of algorithms, artificial intelligence, or other automated systems or tools" (opens in a new tab). Claims made to business buyers are not exempt.

Reviews, testimonials, and platform rules

Texas adds that testimonials must be based upon verifiable facts (opens in a new tab), and the AICPA's confidentiality rule applies to anything a reply or testimonial reveals about a client (above).

Content that complies and still answers the question

Assistants favor specific, checkable facts. In lab trials, being on topic, stating a price, and carrying a recent date raised a source's odds of being cited first in all six models tested (opens in a new tab) (peer-reviewed; laboratory setting). The rules above allow most of those facts. Circular 230 lets tax practitioners publish fixed fees, hourly rates, fee ranges, and consultation fees, and the AICPA and Texas rules are aimed at fee statements that mislead, not at fee statements as such (our reading). Google's systems "give even more weight to content that aligns with strong E-E-A-T" (opens in a new tab) (experience, expertise, authoritativeness, and trustworthiness) for topics that could significantly affect people's financial stability, and its rater guidelines list "Instructions on how to fill out tax forms" (opens in a new tab) among information best left to experts.

Our recommendation: publish each expert article under the name of the professional who wrote or reviewed it, linked to a bio with credentials, and add what your professionals see in client work rather than restating common knowledge, since Google asks for non-commodity content (opens in a new tab).

How to measure SEO and AEO for a professional services firm

Measure AI visibility as a rate across repeated runs, per assistant and per service line, and connect it to new engagements by asking every new client how they found the firm. For local practices, measure per city as well.

Change one thing at a time, keep a group of pages you did not change, and record the date of each change. In the only controlled field study found, ChatGPT referrals to pages that were not changed grew 3.5 times over the same period (opens in a new tab) (preprint; one site), so a before-and-after comparison without a control would have credited that growth to the changes.

How to do SEO and AEO for a professional services firm

These steps are recommendations. Each draws on the evidence above.

1. Know the rules for each credential and state where the firm practices, including record-keeping duties, and decide who approves each page.
2. List the questions buyers ask, by service line and client type, in their words, from sales calls, proposals, and search data. Remove client details.
3. Publish fee information in the forms the rules allow, with what makes a fee change and the date it was set.
4. Make every bio verifiable: license and state, enrolled agent status in the approved wording, industries served, and a link to the public license record.
5. Make the Business Profile, marketplace profiles, and website state the same facts, under the firm's licensed name.
6. Publish expert content under the names of the professionals who wrote or reviewed it, and case studies only with client consent.
7. Ask every client for a review the same way, with no incentive tied to sentiment, and disclose any incentive.
8. Make the pages crawlable and indexable, and keep services, fees, and bios in the HTML.
9. Measure with a fixed prompt panel and a source question, and change one thing at a time.

Checklist for professional services firms

What the evidence shows and does not show

Antipatterns in professional services marketing

Each antipattern below is common in professional services marketing and fails for a documented reason.

Frequently asked questions

Can CPA firms advertise?

Yes. The AICPA code bars advertising or solicitation that is "false, misleading, or deceptive" (opens in a new tab), not advertising itself, and it tells members to follow their state board's rules on the CPA credential. State boards add their own terms; Texas, for example, bars self-laudatory statements and testimonials "not based on verifiable facts" (opens in a new tab). Tax practice adds Circular 230.

Can a CPA advertise low prices?

Fee advertising is allowed within limits. Circular 230 lists the fee information a tax practitioner may publish and requires honoring published rates for at least 30 days; the AICPA bars quoting a fee that is likely to be substantially increased without saying so; and Texas bars fee statements that omit the variables that affect the final fee (rules above).

How do accounting and consulting firms get clients from AI search?

No one can guarantee it; OpenAI says of ChatGPT search results, "Placement is not guaranteed." (opens in a new tab) A firm controls whether its pages can be crawled and whether its facts agree everywhere: publish services, fees, and credentials on its own site, keep marketplace and Business Profile facts identical, and put expert content under named professionals. How to get recommended by ChatGPT covers the details.

Should a professional services firm publish its prices?

In our reading, the evidence leans toward yes, with limits: assistants can state prices whether or not a firm publishes them, and published prices are the only ones a firm controls (sources above). If fees vary by engagement, publish what sets the price, typical ranges, and the date (our recommendation), in the forms the rules allow. No study has measured how publishing fees changes AI recommendations or win rates.

Do accountants need local SEO?

Firms that serve clients in their area do. Google's local results depend on relevance, distance, and popularity (opens in a new tab), 45% of U.S. consumers used AI tools for local recommendations in 2026 (above), and AI engines cited different sources than Google for tax-preparation queries in one preprint (above). Firms that sell nationally depend more on their own sites and marketplaces.

Is AEO worth it for a professional services firm?

The evidence is thin. Business buyers research service providers with AI more than any other category in one survey, but no study measures how often AI decides who is hired. In our view, the lowest-cost parts of the work, such as clear fee pages, verifiable bios, and consistent profiles, also serve referred buyers who check the firm before calling. Is AEO worth it? What the evidence says reviews the general case.

How long does SEO or AEO take for a CPA firm?

No study has measured it. A 2026 review of 45 studies found no technique with a stable, longitudinal, cross-platform causal effect on organic discoverability (opens in a new tab) (preprint), so there is no evidence base for a timeline. Google says crawling a URL "can take anywhere from a few days to a few weeks" (opens in a new tab). Treat a promised timeline as a sales claim.

How much does AEO cost, and which agency should we hire?

We found no published survey of what accounting or consulting firms pay for SEO or AEO. A software company that sells its own AEO product puts agency work at about $3,000 and up for a one-time audit or sprint, and about $9,000 to $15,000 or more a month for ongoing programs (opens in a new tab) (September 2026); the index of what AEO costs compares published prices. AEO HQ sells this work itself (see Answer engine optimization (AEO) services), so we have an interest, and we do not rank agencies. Google says third-party tools "can't guarantee performance," and lists AEO and GEO tools among the services to evaluate critically (opens in a new tab). How to choose an AEO or GEO agency lists the questions to ask; for an accounting firm, add one: will the agency's copy pass the AICPA code and your state board's rules?

Can we name clients or show their logos?

With consent, and with care. The AICPA code bars disclosing confidential client information without the client's specific consent, and it notes that a name alone can be confidential when it reveals something, as in a bankruptcy practice (rules above). Our recommendation: get written consent for every name, logo, and case study.

Next steps

AEO HQ is a professional services firm that sells this work at fixed, published prices, from a $499 automated audit to $8,995 for an audit, a plan, and technical implementation that includes analytics setup. We do not give legal or ethics advice: your firm's professionals approve every claim before it is published. See the prices and what each package includes.
