AEO — or Answer Engine Optimisation, a marketing term for structuring content so AI-powered search tools can more easily understand, extract, and cite it — is becoming a meaningful visibility consideration for professional services firms. When a potential client asks Google AI Mode, ChatGPT, or Perplexity to recommend a solicitor, a mortgage broker, or an IFA, the AI draws from sources it assesses as authoritative, well-structured, and relevant. In many AI-answer experiences, fewer sources are surfaced prominently than in a traditional results list — which means whether your firm is mentioned at all can matter more than where you rank on page two. For professional services, this is worth understanding now.

What AEO actually is — and how it differs from the SEO you already know
Most professional services firms have some understanding of SEO: write content around the keywords your clients search for, structure it correctly, build authority over time, and you earn visibility in Google’s organic results. That model is still valid. But it describes only one of the two search experiences your potential clients now use.
SEO earns you a position. AEO is about being in the answer.
When someone searches Google using a traditional query, they get a list of results and choose which one to click. Your goal is to appear high on that list. Clicks, traffic, and enquiries follow.
When someone uses Google AI Mode, ChatGPT, Perplexity, or any similar AI-powered tool, the experience is different. They ask a question — often a long, specific, conversational question — and the AI synthesises an answer from across the web and delivers it directly. It may name specific firms or providers. It may recommend a course of action. It may summarise the key considerations and suggest the best next step. The user gets an answer, not a list.
In that model, appearing in the answer has a different kind of value to appearing on page two of organic results. AI tools typically surface fewer sources than a traditional results page, so inclusion in the answer tends to matter more than a lower-ranking position in a list. This is what AEO is about: structuring your content so that when an AI tool answers a query relevant to your firm, your content is easy to extract, verify, and cite.
Why Google I/O 2026 made this timely for professional services firms
In May 2026, at its annual developer conference, Google announced that AI Mode — its AI-powered search experience — had surpassed 1 billion monthly active users (source: blog.google, 19 May 2026). In Sundar Pichai’s words: “AI Mode has been a revelation, our biggest upgrade to Search ever.” At the same time, Google AI Overviews now have 2.5 billion monthly active users (same source). These figures confirm that AI-powered search is no longer an opt-in feature. It is the default search experience for a large and growing share of users — including those searching for professional services.
If you are a solicitor, an IFA, or a mortgage broker, your potential clients are encountering AI-generated answers when they search for firms like yours. The question is whether those answers mention you.
Why AEO matters more in high-trust professional services sectors
AEO considerations affect every industry. But they affect regulated professional services differently — and more acutely — than most.
Fewer sources are surfaced in AI answers
In traditional Google search, clicks are distributed across multiple results. The top organic result earns the largest share, with positions two through ten each receiving progressively smaller but still meaningful fractions of available traffic. There is a spread.
AI-generated answers tend not to work that way. When an AI names providers in a category, it typically names a small number. Research from Ahrefs, published in early 2026, analysed 863,000 keyword SERPs and found that only 38% of pages cited in Google AI Overviews also ranked in the top ten organic results — down from 76% in Ahrefs’ earlier study from mid-2025 (source: ahrefs.com). AI citation appears to be increasingly decoupled from traditional ranking position. A firm can rank organically and still be absent from the AI answer. Equally, a well-structured piece from a smaller firm can be cited even without high domain authority, if the content is built to answer the query precisely.
For professional services firms where a single client instruction can be worth thousands of pounds in lifetime value, this dynamic is worth paying attention to.
Law firms, IFAs, and mortgage brokers face a higher credibility bar
Google’s published quality-rater guidance describes high-stakes “Your Money or Your Life” topics — including legal, financial, and medical content — as requiring high E-E-A-T: Experience, Expertise, Authoritativeness, and Trustworthiness. Google notes that quality raters use this framework to evaluate content; it does not publish a direct algorithmic formula for how this affects ranking or citation. But the logic applies to AI search: when a query involves choosing a law firm, selecting a financial adviser, or understanding a mortgage option, there is good reason to expect AI systems to favour well-sourced, authoritative content over loosely evidenced claims (source: Google Search Quality Evaluator Guidelines).
For regulated sectors, this creates both a challenge and an opportunity. The challenge: generic, loosely sourced content is less likely to be cited when an AI is answering a question about which IFA a potential client should consult, or how a law firm approaches a particular practice area. The accuracy bar is higher. The opportunity: if your content is specific, accurate, verifiable, and structured around genuine questions, it produces credibility signals that vague or AI-generated competitor content cannot. Specialist, verifiable content from a firm that operates in a regulated sector — where accuracy is a professional obligation, not just a preference — tends to be more citable than broad, generic content from a larger but less specialist competitor.
If you work with IFAs navigating AI search or are thinking about how SEO and AEO intersect for regulated firms, this dynamic matters from the start.
What the evidence suggests helps AI citation
No single source publishes a definitive AI-citation formula. Google and the major LLM providers have not released a checklist equivalent to the structured data documentation for traditional rich results. But patterns from current research, combined with the logic of how retrieval systems work, point to several consistent signals. These are best practices, not guarantees.
Answers near the top of the page
AI retrieval systems are designed to extract citable answer fragments from the pages they index. A page that leads with a clear, direct answer to the query is easier for a retrieval system to cite than a page that buries the answer after several paragraphs of preamble. This is not a formal rule, but it is a strong practical pattern: pages that answer the query clearly near the top tend to be easier for AI systems to extract and summarise.
For professional services content, this means articles that open with a general introduction to the topic — before eventually arriving at the point — may perform less well in AI citation contexts than articles that answer the question in the opening paragraph.
Structured data
Google deprecated FAQ rich results — the dropdown Q&A sections that appeared in traditional search results — on 7 May 2026 (Google structured data documentation, May 2026). The rich result feature is gone: FAQ dropdowns no longer appear in Google Search. But FAQPage remains a valid Schema.org type, and valid structured data that you have left in place does not harm Google Search performance — Google has stated that unused structured data does not cause problems. For non-Google systems, FAQPage remains a valid schema.org type; some industry guidance suggests other search and AI systems may still parse it, though the evidence on whether JSON-LD markup directly improves AI citation rates is mixed.
More broadly: structured data — Article schema, BreadcrumbList, and FAQPage where a FAQ section is present — helps retrieval systems interpret your content with less ambiguity. For many professional services articles, these are sensible defaults: Article and BreadcrumbList schema provide useful context, and FAQPage schema is appropriate where a genuine FAQ section exists and reflects the page content accurately.
E-E-A-T signals
Google’s E-E-A-T framework — Experience, Expertise, Authoritativeness, Trustworthiness — was developed for the search quality rater guidelines, used by human raters to evaluate content quality. Google states that these rater evaluations help assess its search systems; they are not themselves a direct ranking or citation mechanism. The signals that help quality raters assess E-E-A-T, however, are the same kinds of signals that make content more useful to AI retrieval systems:
- Specific claims with verifiable sources — not “SEO can improve your visibility” but a specific claim tied to a named study, with a date, that can be confirmed
- Verified factual accuracy — content whose claims can be confirmed from primary sources is more reliable than content that sounds plausible but cannot be checked
- Consistent publication — a site with ten well-structured, factually consistent articles on a topic tends to be assessed as more topically authoritative than a site with one article
- Named, qualified expertise — for professional services, this includes communicating the firm’s credentials, regulatory standing, and specific areas of practice
Regulated professional services firms already operate in an environment where accuracy and verifiability are professional obligations. That same discipline, applied to content production, tends to produce content that performs better in AI citation contexts.
Specific, verifiable content
The most defensible path to AI citation is content that is genuinely useful: specific, structured, factually accurate, and built around the actual questions your clients are asking. This requires a production process — not just a topic list and a writer. For the practical step-by-step on building content AI systems will cite — covering structure, schema, inline citations, and topical clusters — see our guide on how to optimise content for AI search.
What AEO-ready content looks like in practice
The gap between “content that ranks reasonably well” and “content that gets cited by AI tools” is often narrower than it appears — but it does require getting the article structure right.
The structure of a more citable article
A professional services article designed to perform in both organic search and AI citation contexts tends to share these characteristics:
It answers the query clearly near the top. The first paragraph addresses the question. Not context, not background — the answer.
It uses a summary table or quick-reference block near the top. Structured summaries with clear fields and accurate values are easy for retrieval systems to extract. A well-formatted table is a self-contained citation unit.
It organises the body around reader questions, not topic categories. An article structured around “H2: Types of Mortgage Broker” is a topic article. An article structured around “H2: Why most mortgage broker blogs generate no enquiries” addresses a question. AI systems serve question-askers. Content that mirrors that structure tends to be more extractable.
It places citations and verification signals inline. A claim supported by a named source cited at the specific sentence where the claim appears is more credible than a claim followed by a footer list of sources. This applies to regulatory citations (FCA guidelines, SRA principles, Law Society guidance), industry research, and statistical claims.
It includes a well-structured FAQ section. Six to eight questions, written as real search queries, with self-contained answers of two to four sentences each. The answers should make sense without the surrounding article, because an AI may extract them independently.
It implements Article, BreadcrumbList, and FAQPage schema in JSON-LD in the <head> of the page, where a genuine FAQ section exists.
The AEO discipline — fact verification, structured data, citation-optimised architecture — has to be built in from the brief stage, not added at the end. See how we build it for professional services firms.
Why most professional services content may fall short of this standard
Most professional services content — including content that ranks reasonably well in traditional Google search — may not meet the AEO citation bar for one of three reasons.
The first is structural: the content buries its answer. Many law firm and IFA blog posts open with scene-setting before reaching the point. Retrieval systems looking for extractable answer fragments cannot use this content as efficiently, even if the answer is good.
The second is specificity: the content makes general claims. “Content marketing can help law firms attract clients” is a statement, not an answer. A specific, verifiable claim tied to a named source tends to be more useful to a system that is synthesising an answer to a reader’s question.
The third is verification: the content cannot be checked. For regulated sectors, content whose claims cannot be confirmed from primary sources carries greater risk in the AI citation context. If your article about SRA compliance or FCA-regulated mortgage advice contains statements that a retrieval system cannot easily verify, it is a weaker citation candidate than an article whose claims are clearly sourced.
This is why how we build content for professional services firms uses a documented nine-step production process — not because nine steps sounds impressive, but because the AEO discipline (fact verification, structured data, citation-optimised article architecture) has to be built in from the brief stage, not added at the end. See how we build it for professional services firms.
AEO and SEO are not separate strategies — here is why that matters
There is a tempting framing of AEO as the “next thing” after SEO — as if firms should replace one strategy with another. This is not the right framing.
Traditional organic search has not disappeared. Google’s organic results still exist and still drive meaningful traffic for well-ranking content — particularly for BOFU commercial queries where users are actively choosing between providers. For professional services firms targeting in-market buyers via queries like how SEO works for UK law firms or SEO for IFAs, traditional SEO returns are still real and still worth building.
What has changed is that a well-built SEO article — structured around a clear answer, supported by verified citations, with clean schema markup — is also a stronger AEO candidate. The two are not in tension. Content built to a high standard tends to perform better in both environments: it earns Google rankings via traditional signals, and it produces the kind of extractable, verifiable content that AI systems can work with.
The risk is not that SEO and AEO are competing strategies. The risk is producing content that performs well in neither — generic, loosely structured, unverified content that is progressively less competitive as AI Mode and AI Overviews handle a growing share of queries.
For firms thinking about their content investment, the standard for “good enough” is rising. Content produced in 2022 to a lower standard may not perform well in the 2026 AI-search environment. The firms that build to the current standard now — rather than retroactively updating content that was never designed for this environment — are likely to accumulate a compounding advantage over those that wait.
This is also true for the content marketing for mortgage brokers and content marketing for surveying firms content already live on this site: every piece is built to AEO-ready standards from the first draft, not retrofitted.

Frequently asked questions
What is AEO (Answer Engine Optimisation)?
AEO — Answer Engine Optimisation — is a marketing term for structuring content so that AI-powered search and answer tools can more easily extract and cite it. Where SEO focuses on earning a position in a list of search results, AEO focuses on being mentioned or cited inside the AI’s answer. For professional services firms, this is relevant because AI tools like Google AI Mode, ChatGPT, and Perplexity are increasingly part of how prospective clients research which firm to approach.
How does AEO differ from SEO for professional services firms?
SEO earns you visibility in Google’s organic results. AEO is about being cited — mentioned or referenced — inside an AI-generated answer. The two are not mutually exclusive: content built to AEO standards (direct answers, verified claims, clean structured data) tends also to be strong SEO content. The key difference is emphasis: AEO requires leading with the answer, structuring content around real questions, and ensuring factual accuracy from the first draft.
Does AEO replace SEO?
No. Traditional organic search still drives meaningful traffic, particularly for commercial queries where users are actively choosing between providers. What has changed is that the quality signals that help content rank in organic search — clear answers, specific verified claims, good structure — are increasingly the same signals that make content easier for AI systems to cite. Content that performs well on both tends to outperform content optimised for only one.
What schema markup should professional services firms consider for AEO?
For many professional services articles, three schema blocks are worth considering: Article schema (identifies the content type and publication details), BreadcrumbList schema (signals site hierarchy), and FAQPage schema where a genuine FAQ section exists and accurately reflects page content. Note that Google deprecated FAQ rich results in May 2026 — FAQ dropdowns no longer appear in Google Search — but FAQPage remains a valid Schema.org type. Whether it directly influences AI citation rates is an open question; the visible Q&A content on the page is the more reliably impactful element.
How long does AEO take to produce results for a law firm or IFA?
Timelines vary significantly depending on domain authority, query competitiveness, crawl frequency, and content quality. In our experience, well-structured content on lower-competition professional services keywords may begin appearing in AI citations within weeks of publication — but this is not guaranteed and varies considerably. Building consistent citation presence across a topic area typically requires months of systematic content production. We would caution against expecting fast, predictable results: AEO is an emerging discipline and the signals that drive citation are not fully published or stable.
Does my content need to change to work for both Google and AI search?
Not necessarily change — but it does need to meet a higher standard than content produced before AI Mode became widely adopted. Specifically: answers should appear early, claims should be verifiable from named sources, and the article should include a FAQ section with self-contained answers and accurate structured data. Content that already meets these standards is well-positioned. Content that does not may need to be updated.
Can a small professional services firm compete in AI search against larger firms?
Potentially yes — and this is one of the more interesting early findings. Ahrefs’ 2026 research found that only 38% of pages cited in Google AI Overviews rank in the organic top ten. AI citation appears to be increasingly decoupled from traditional domain authority, which means specialist, well-structured content from a smaller firm may be cited alongside or ahead of generic content from a larger competitor. This is not a guarantee, but it suggests that quality and specificity matter more in this environment than scale alone.
What did Google I/O 2026 announce that changed AI search?
At Google I/O on 19 May 2026, Google announced that AI Mode — its AI-powered search experience — had surpassed 1 billion monthly active users, and described it as “our biggest upgrade to Search ever.” Google AI Overviews, which appear above traditional organic results for a large share of queries, now have 2.5 billion monthly active users. Both figures confirm that AI-powered search is now a primary, mainstream experience — not a feature used only by early adopters.
