In-house counsel are researching your firm via AI before you know they exist
The panel review process has always been opaque to law firms. By the time a general counsel issues an RFP or a procurement team sends an invitation to tender, the real decision-making has already narrowed the field. Firms that did not make the initial longlist never learn they were excluded.
What has changed — decisively — is how that longlist is compiled. In-house legal teams are increasingly using AI search tools to research firms, compare practice areas, and validate credentials before any formal process begins. A head of legal asking Gemini “best M&A law firms for mid-market deals in the UK” or a company secretary querying ChatGPT about “commercial property solicitors with logistics sector experience” is not a hypothetical scenario. It is happening now, at scale.
If your firm is not appearing in these AI-generated responses, you are being excluded from shortlists you never knew existed. And by the time the RFP arrives — if it arrives at all — the instructing party already has a preferred firm in mind. One that the AI recommended.
The AI Discovery Problem for Commercial Law Firms
UK commercial law has historically relied on a well-understood discovery hierarchy: personal relationships, industry reputation, Chambers and Legal 500 rankings, and professional referral networks. These channels still matter. But a new layer has been inserted at the very top of the research process — one that most firms are entirely unprepared for.
AI-powered search engines synthesise information from multiple sources to construct an answer, not a list of links. When an in-house lawyer asks about firms with expertise in a specific practice area, the AI model evaluates published content authority, directory presence, third-party citations, and entity signals to determine which firms to name.
The structural problem for many commercial firms is that their online presence is built for traditional SEO: a well-designed website, some keyword-optimised practice area pages, and a Google ranking strategy. But AI models do not rank pages. They evaluate authority, specificity, and corroboration across sources. A generic “Our Commercial Property Team” page that reads identically to fifty competitors provides the AI with nothing to differentiate.
The firms winning in AI search are the ones with deep, specific, regularly updated content that demonstrates genuine expertise — not marketing copy, but substantive analysis that an in-house lawyer would actually find useful.
How GEO Works for Commercial Law Firms
Generative Engine Optimisation for commercial law firms requires a strategy built around three distinct authority layers.
Practice area content depth. AI models reward specificity. A firm that publishes detailed analysis of the Leasehold and Freehold Reform Act 2024’s implications for commercial landlords will be cited for commercial property queries long before a firm with a generic practice area page. The content must be technically rigorous — in-house lawyers are sophisticated readers who will immediately recognise surface-level marketing. Briefing notes, sector updates, deal commentary (within confidentiality constraints), and regulatory analysis all build the content authority that AI models draw on.
Chambers and Legal 500 citation alignment. The legal directories remain among the most authoritative third-party sources that AI models reference when evaluating law firm expertise. But the relationship between directory rankings and AI visibility is not automatic. Your firm’s Chambers and Legal 500 profiles need to be actively aligned with your GEO strategy — ensuring that the practice area descriptions, key contacts, and notable work cited in directories are consistent with and reinforced by your website content, published articles, and partner profiles.
Partner thought leadership as entity authority. AI models increasingly attribute expertise to individuals, not just organisations. A partner who regularly publishes substantive commentary on their practice area — through legal publications, industry journals, LinkedIn articles, and conference presentations — builds a personal entity authority that the AI model associates with the firm. This is not vanity publishing. It is a strategic authority signal that directly influences whether the firm is cited in AI responses.
The SRA Compliance Dimension
The Solicitors Regulation Authority’s rules on publicity create specific parameters for law firm GEO that generic marketing agencies routinely overlook.
SRA standards require that all publicity is accurate, not misleading, and does not diminish trust in the profession. Claims about expertise must be substantiable. Client testimonials and case studies must not breach confidentiality obligations. Fee information, where published, must be clear and accurate.
For GEO, this means that the social proof signals which work in other sectors — client reviews, outcome-based case studies, comparative claims — must be handled with care. What works exceptionally well within SRA parameters is exactly what AI models value most: substantive, authoritative content that demonstrates expertise through analysis rather than assertion.
Published legal commentary, sector briefings, and regulatory analysis are both SRA-compliant and GEO-effective. The constraint, properly understood, is a competitive advantage — it forces the kind of substantive content production that AI models reward.
Key AI Queries for Commercial Law Firms
The queries that matter most for commercial law GEO reflect how in-house counsel actually research firms:
- “Best M&A law firm UK” — a high-value practice area query where Chambers citations, deal track record, and published transaction commentary dominate
- “Commercial property solicitors London” — a location-qualified practice query where local authority signals and sector-specific content differentiate
- “Law firm for Series A funding round” — a transaction-specific query where demonstrable startup and venture capital expertise signals are critical
- “Employment law firm for TUPE transfers” — a specialist query where deep, technical content on a specific legal area wins disproportionate citation
- “Best litigation solicitors for contractual disputes UK” — a dispute-focused query where published case analysis and dispute resolution expertise signals matter
Each query type requires different content and entity strategies. Firms that approach GEO as a single initiative rather than a practice-area-specific programme will consistently underperform.
The Synaptic Authority Engine for Commercial Law
MarGen’s Synaptic Authority Engine applies our proprietary methodology to the specific dynamics of commercial law firm visibility. The Engine operates across three interconnected layers.
The audit layer establishes your firm’s current AI search presence. What do ChatGPT, Gemini, Perplexity, and Copilot say when asked about your firm, your practice areas, and your key partners? How do you compare against the firms being cited for your target queries? The gap analysis provides the strategic foundation.
The entity layer ensures that your firm’s authority signals are complete, consistent, and correctly structured across all the sources AI models reference: SRA records, Chambers and Legal 500 profiles, your website’s structured data, partner profiles on legal publications, and professional body memberships (Law Society specialist panels, sector associations).
The content layer builds the practice-area-specific, technically substantive content that AI models cite. Not marketing copy — genuine legal analysis, sector commentary, and regulatory briefings that demonstrate the expertise in-house counsel are looking for. Published, attributed, and structured for AI extraction.
The result is a firm that AI models cite with confidence — because the authority is real, multi-sourced, and verifiable.

Most commercial law firms have never checked what AI search engines say about them. The results are frequently surprising — and not always in a positive direction. Our free AI Visibility Audit reveals exactly how your firm appears across ChatGPT, Gemini, Perplexity, and Copilot for your key practice areas, and identifies the specific authority gaps your competitors may already be filling.
