What is GEO and why it matters now

Generative Engine Optimisation (GEO) is the practice of optimising your online presence so that AI search platforms — ChatGPT, Perplexity, Gemini, Claude, and others — cite and recommend your firm in their responses. It’s the newest discipline in digital marketing, and for law firms, it’s no longer theoretical.

The shift is straightforward. When someone asks Google “best divorce solicitor in Manchester”, they see a page of links and choose which to click. When someone asks ChatGPT the same question, they get a single synthesised response — often naming specific firms, explaining what to look for, and citing sources. There’s no page two. There’s no “near the top of the results”. You’re either in the response or you’re not.

This matters now — not in the future — because adoption has crossed the threshold from early-adopter novelty to mainstream behaviour. As the platform data in this report shows, tens of millions of UK users are already using AI tools to search for information, make local decisions, and research professional services. The firms that appear in those AI responses are capturing enquiries that would previously have gone through Google. The firms that don’t are invisible in a rapidly growing channel.

GEO is distinct from AEO (Answer Engine Optimisation), which focuses on answer features within Google’s own search results. GEO targets a fundamentally different set of platforms — third-party AI systems that maintain their own indexes, citation patterns, and ranking signals. The overlap exists (strong organic authority helps in both), but the optimisation strategies diverge in important ways that this report examines.

For a complete introduction to both disciplines, see our guide to GEO and AEO for law firms.

The AI search platforms: scale and UK adoption

The scale of AI search platform adoption is now large enough to affect law firm client acquisition in measurable ways. Here is where each major platform stands.

ChatGPT

OpenAI reports that ChatGPT now serves over 900 million weekly active users globally. In the UK specifically, Ofcom’s Online Nation report found approximately 16 million monthly active UK users. Backlinko’s traffic analysis shows UK-based visits to ChatGPT reached 1.8 billion in 2024 — a 389% year-on-year increase.

ChatGPT’s integration of web search (via Bing) and its growing use as a direct search tool — rather than just a conversational assistant — means an increasing share of these users are asking it questions that would previously have gone to Google. “Find me a good immigration solicitor in Birmingham” is no longer a hypothetical use case. It’s happening at scale.

Perplexity

DemandSage’s Perplexity analysis reports over 45 million monthly active users globally, processing over 780 million search queries. Perplexity is explicitly positioned as a search engine — every response includes cited sources with links, making it the most transparent of the AI search platforms. UK usage has grown over 100% year-on-year.

For law firms, Perplexity is particularly significant because of its citation-heavy approach. When a user asks Perplexity about legal services, the response includes numbered references to specific webpages. The firms whose websites, directory listings, and media coverage appear in those citations receive direct referral traffic — measurable in analytics, just like any other referral source.

Gemini

Google’s own AI assistant, Gemini (formerly Bard), has over 750 million monthly active users globally, powered by its integration into Google’s ecosystem — Android, Google Workspace, and Google Search itself. UK adoption grew 146% year-on-year.

Gemini’s significance for law firms is twofold. First, it powers Google’s AI Overviews (covered in our AEO report). Second, it operates as a standalone AI assistant that users can ask directly about legal services. Its deep integration with Google’s index means it draws heavily on the same signals that determine organic rankings — making traditional SEO directly relevant to Gemini visibility.

Claude

Anthropic’s Claude has seen UK adoption grow 138% year-on-year, according to Backlinko’s comparative platform analysis. While smaller in absolute terms than ChatGPT or Gemini, Claude is increasingly used in professional contexts — including legal research — due to its handling of nuanced, complex queries and its capacity for processing long documents.

The combined picture is clear: hundreds of millions of users are now searching through AI platforms, and UK adoption is growing at triple-digit rates. These aren’t separate from your potential clients — they are your potential clients, using a different tool to find the same legal services.

How AI platforms are changing local discovery

The most immediate impact of AI search on law firms is in local discovery — how people find and choose local service providers. The data here is unambiguous and the shift is accelerating.

BrightLocal’s 2026 Local Consumer Review Survey found that 45% of consumers now use AI tools for local business recommendations — up from just 6% the previous year. That’s not a gradual trend. That’s a step-change in consumer behaviour, driven by the mainstreaming of ChatGPT and the integration of AI features into Google and Apple’s ecosystems.

The same survey found that Google’s share of local business discovery dropped from 83% to 71% in a single year. Google remains dominant — but it’s losing share at a rate that would have been unthinkable 24 months ago. The share isn’t disappearing; it’s being redistributed to AI platforms, social media, and direct recommendation tools.

For law firms, this means the Local Pack and organic Google results — while still critical — are no longer the only places where potential clients discover solicitors. When someone asks ChatGPT “can you recommend a family solicitor in Leeds”, the response draws on web content, directory listings, review aggregation, and other signals to generate a recommendation. The firms with strong, consistent online presences across multiple platforms are the ones that surface in these responses. The firms that exist only as a Google Business Profile and a basic website are increasingly invisible on this new channel.

The practical implication: local SEO for law firms now needs to account for AI discovery alongside traditional Google optimisation. Your Google Business Profile still matters — enormously. But so do your presence in legal directories, your review profile, your website content, and the breadth of your online footprint. AI models aggregate all of these signals. A firm with five-star Google reviews, comprehensive directory listings, and detailed practice-area pages on its website will be cited by AI platforms far more often than a firm with a thin web presence, regardless of its Google ranking.

What AI platforms cite and why

Understanding how AI platforms select and cite sources is fundamental to GEO. Unlike Google’s PageRank — where the algorithm is well-studied, if not fully transparent — AI citation patterns are less understood. But emerging research is beginning to map the landscape.

TryProfound’s analysis of AI citation patterns found significant differences between platforms. ChatGPT’s most-cited domain is Wikipedia, at 7.8% of all citations. Perplexity’s most-cited domain is Reddit, at 6.6%. This reflects the different architectures: ChatGPT draws heavily on its training data (where Wikipedia is overrepresented), while Perplexity performs real-time web searches and surfaces sources that are frequently linked to and discussed — Reddit being a prime example.

A striking finding: Perplexity cites approximately 2.76 times more sources per response than ChatGPT. This makes Perplexity a significantly larger citation opportunity — for every question asked, more websites have a chance of being referenced. However, only 11% of domains cited by one platform are also cited by the other. The citation patterns are largely non-overlapping, meaning that optimising for one platform doesn’t automatically optimise for the other.

Citation accuracy is also a concern. Research from the Tow Center for Digital Journalism via the Nieman Lab found that over 60% of AI search engine citations contain some form of inaccuracy — ranging from slightly misattributed claims to sources that don’t support the statements made. This has practical implications for law firms: even when your website is cited, the AI-generated text surrounding the citation may not accurately reflect your content. Monitoring AI mentions is important for reputation management.

What increases your chances of being cited? The research points to several factors:

• Authority signals: Websites with strong backlink profiles, high domain authority, and established reputation are cited more frequently. This aligns directly with traditional SEO authority.
• Content structure: Clear, well-organised content with explicit answers to specific questions is easier for AI models to extract and cite. Unstructured walls of text are harder to parse and less likely to be referenced.
• Recency: AI platforms with web search capabilities (Perplexity, ChatGPT with browsing) favour recently published or updated content. Stale pages are less likely to be cited than current ones.
• Source diversity: Firms mentioned across multiple sources — their own website, directories, media coverage, professional bodies — are more likely to surface in AI responses because the AI model can corroborate the information from multiple inputs.
• Specificity: Generic content that could apply to any law firm is less citeable than content specific to a practice area, jurisdiction, or locality. “We offer expert legal services” is invisible to AI. “Our Manchester family law team has handled over 500 divorce cases since 2018” gives the AI something concrete to reference.

For law firms, the citation strategy maps closely to a strong content and authority strategy: build comprehensive, specific, well-structured content; earn citations and mentions from authoritative sources; maintain accurate, consistent listings across the web. The firms already doing this well for traditional SEO have a significant head start in GEO.

UK workplace and consumer AI adoption

The adoption of AI tools in the UK has crossed from niche to mainstream in a remarkably short timeframe. Understanding the scale helps contextualise why GEO matters now.

IAB UK’s Generative AI Report found that 49% of UK workplaces now use AI tools — up from 32% the previous year. This includes law firms themselves, many of which are using AI for legal research, document drafting, and case analysis. The same tools that solicitors use internally are the ones their potential clients are using to find them.

Consumer AI adoption is equally dramatic. The Reuters Institute Digital News Report found that 24% of UK adults now use AI tools weekly for information-seeking — double the 11% recorded the previous year. For a tool category that barely existed in public awareness three years ago, this represents extraordinary adoption velocity.

The demographic distribution matters for law firms. AI adoption is highest among 18-34 year-olds and higher-income professionals — demographics that are increasingly likely to need legal services (property transactions, employment disputes, family matters). It’s lowest among over-65s, though adoption in this group is growing from a low base. The practical effect: the consumers most likely to use AI search for finding solicitors are those in the prime age range for needing solicitors.

Ofcom’s data adds another dimension: 30% of UK internet users reported using AI-supported search tools specifically — not just chatbots, but AI-enhanced search experiences including Google’s AI Overviews and standalone tools like Perplexity. This figure has grown quarter-on-quarter since tracking began and shows no sign of plateauing.

The workplace adoption figure has an additional implication. As professionals become comfortable using AI tools at work, they bring those habits home. A solicitor who uses AI daily for research will naturally use it for personal decisions too — including recommending professionals to friends and family. The referral network, long the backbone of legal client acquisition, is itself being mediated by AI.

The Google problem: declining discovery share

Google’s 93.35% share of UK search engine queries, documented in our State of Legal SEO report, remains formidable. But that figure measures traditional search — queries typed into a search engine. It doesn’t capture the growing share of discovery that bypasses search engines entirely.

BrightLocal’s data — showing Google’s share of local business discovery dropping from 83% to 71% in one year — captures a different metric: where consumers actually start when they need to find a local service provider. The 12-percentage-point drop represents a structural shift. Some of that share went to AI platforms. Some went to social media (TikTok, Instagram, Reddit). Some went to direct recommendation tools and review platforms.

The zero-click trend compounds this. As documented in our SEO report, only 43.5% of EU and UK Google searches result in a click to an organic website — down from 47.1%. Google is increasingly answering queries on its own results page, through AI Overviews, featured snippets, and knowledge panels. The user gets their answer without ever visiting a website. For law firms, this means that even when someone does use Google, the chance of them clicking through to your website is declining year-on-year.

The combined picture: fewer people are starting with Google for local discovery (83% to 71%), and those who do use Google are less likely to click through to a website (47.1% to 43.5%). These trends are multiplicative. A firm that relied on Google for 83% of its discovery and converted 47% of those searches into website visits is now looking at 71% discovery share and 43.5% click-through — a compounded decline in actual website traffic from Google, even if their rankings haven’t changed.

This doesn’t mean Google is becoming irrelevant. It remains — by a large margin — the single most important discovery channel for UK law firms. But it’s no longer sufficient on its own. The firms that treat Google as their only source of online visibility are ceding a growing share of the market to competitors who are visible across AI platforms, directories, social channels, and the broader web.

The strategic response isn’t to abandon Google optimisation. It’s to build a broader presence that serves both traditional search and AI discovery — because the same content authority, structured data, and online reputation that drive Google rankings are also the signals that AI platforms use when selecting sources to cite. A firm investing in comprehensive SEO, local SEO, and GEO is building one foundation that serves all channels simultaneously.

What this means for your firm

The data in this report converges on five priorities for UK law firms navigating the AI search transition.

1. Accept that AI search is a real acquisition channel — now. 45% of consumers using AI for local recommendations; 16 million UK ChatGPT users; triple-digit growth across every platform. These aren’t projections. They’re current figures. Your competitors’ potential clients are already asking AI platforms for solicitor recommendations. The question is whether your firm appears in those responses.

2. Build content that AI models can cite. AI platforms cite specific, authoritative, well-structured content. Vague service descriptions and generic marketing copy are invisible to them. For each practice area, create detailed, factual content that answers the exact questions clients ask — with specific data, clear processes, and local relevance. This is the content that both Google and AI platforms will reference. Our GEO and AEO service helps firms build exactly this kind of content.

3. Diversify your online presence beyond your website. AI platforms aggregate signals from across the web. A firm with a strong website but no directory listings, no media coverage, and no review presence gives AI models less to work with. Ensure your firm is accurately listed in the major legal directories (Law Society, SRA register, Chambers, Legal 500), has a comprehensive Google Business Profile, and actively manages its review profile. Each additional authoritative mention of your firm increases the probability of AI citation.

4. Monitor your AI visibility. Most law firms have no idea whether AI platforms are recommending them — or recommending their competitors. Periodically test the major platforms by asking them the questions your clients ask: “best family solicitor in [your city]”, “how to find a personal injury lawyer in the UK”, “recommend a solicitor for [practice area]”. Document which firms are being cited and what sources are being referenced. This gives you a baseline to optimise against.

5. Don’t abandon Google — layer GEO on top of SEO. Google still accounts for 93.35% of UK search queries and 71% of local discovery. The organic fundamentals documented in our State of Legal SEO report, and the answer engine features covered in our State of Legal AEO report, remain the bedrock. GEO is an additional layer — one that compounds the value of your existing SEO investment. The same authority, content quality, and technical foundation that drive organic rankings also make you more likely to be cited by AI platforms. Build the foundation right, and it serves every channel.
