AEO Agencies for B2B Law Firms: Top 6 for 2026.
The best AEO agencies for B2B law firms treat "who should we hire" as a question with a short, winnable answer list, not a crowded one. Our nearest proxy inside an adjacent deal-advisory category backs that up directly. In our October 2026 measurement of who AI engines recommend for sell-side M&A advisors, a category corporate counsel is hired alongside constantly, Houlihan Lokey was named in 26 of 58 answers, Lincoln International in 24, and Harris Williams in 19, while 80 of the 140 firms named across the run appeared in only one answer (who AI recommends: sell-side M&A advisors). That is a field with no entrenched winner and a long tail doing almost all of the losing. A corporate or transactional law firm sits in the same kind of trust-led, people-not-product category, which is exactly why showing up by name in an AI answer is winnable rather than hopeless.
If you are shortlisting an AEO agency to help a law firm get named when a buyer asks ChatGPT or Google AI Overviews who handles this kind of matter, this page narrows the field to six worth checking, verified against each provider's own site on the day this was written. AEO agencies for B2B law firms are a different buyer than accountancy or consultancy more broadly, which is the vertical covered by our wider AEO agencies for accounting firms guide and by SourceRank's measured AEO agencies page for professional services, which ranks real citation counts across law, accountancy and consulting together. This list is narrower on purpose: corporate and commercial legal work only, not personal-injury or consumer-facing practices, because the content, the proof points and the buyer question are all different.
We publish this list and SourceRank AI is our own service; the other five are ranked on the criteria below.

How we chose
Every provider on this list of AEO agencies for B2B law firms had to name AEO, GEO or AI search optimisation as an actual service, not a generic SEO page with "AI" added to the title. Within that set we weighed:
- 1. Corporate-legal fit, checked honestly. A law-firm case study is not automatically relevant. We checked whether the named proof point is corporate or transactional work, or whether it is personal-injury or consumer law, and said so plainly either way.
- 2. Checkable proof. A named client beats an anonymised one, and an anonymised result with real figures beats a bare claim.
- 3. Pricing transparency, because a managing partner or marketing director qualifying five vendors cannot run five discovery calls just to learn who is even in budget.
- 4. What is actually measured. Several providers in this space use "AI visibility" loosely. We checked whether each one names which engines it tracks and how, not just rankings.
The 6 best AEO agencies for B2B law firms
1. SourceRank AI
SourceRank AI is a done-for-you Answer Engine Optimisation service for B2B companies, based in Aarhus, Denmark, part of the Danish Lead Co group. It measures how often ChatGPT, Gemini, Microsoft Copilot, Google AI Mode and Google AI Overviews name a firm across a fixed set of the questions its buyers actually ask, then does the fix work: entity and schema structure, answer-shaped content, and the third-party citations the engines pull from. The tracking dashboard is included; there is no software handed to your team to run. Pricing starts at a $497 one-time AI visibility audit, with monthly plans from $997.
Best for: A corporate law firm that wants a measured citation rate before it pays for content nobody can verify moved the number.
2. 9Sail
9Sail is a law-firm-only marketing agency with a dedicated page for generative engine optimisation, stating plainly that "GEO for law firms is how your firm gets named when prospects ask ChatGPT, Perplexity, or Google's AI Overviews who to hire" (9sail.com/law-firm-geo). It names real clients on-site, including Peters Brovner LLP, Jacobs Berger LLC, Romano Law and Berardi Immigration Law. Pricing is not published; the firm describes "premium positioning with custom strategies rather than standardized packages" (9sail.com/working-with-9sail).
Best for: A firm that wants a specialist built only for law, understanding that its named proof skews toward litigation, employment and immigration practices rather than transactional corporate work.
3. Maximus Labs
Maximus Labs runs dedicated AEO and GEO service lines with published, tiered pricing, and states its thesis directly: "Law firms, consulting companies, accounting firms, and advisory practices sit on a goldmine of GEO-ready content: expert opinions, practice area depth, case outcomes (anonymized), and regulatory expertise" (maximuslabs.ai/services/geo). Its published case studies, however, are all technology companies, not law firms. Tiers run from $2,000-$3,000/mo for a basic audit-and-schema engagement up to $15,000-$50,000+/mo at enterprise scope.
Best for: A firm that wants transparent, tiered pricing and a stated rationale for why legal content fits GEO, without yet a named legal client as proof.
4. First Page Sage
First Page Sage claims to have launched the first dedicated GEO service in May 2023 and publishes both a general AEO services page and a dedicated law firm AEO/GEO page. Its one named legal case study, though, is an anonymised "Los Angeles-based personal injury law firm," not a corporate or commercial practice; its enterprise client roster (Logitech, Salesforce, U.S. Bancorp) establishes general B2B credibility but not legal-sector proof. The firm has self-reported pricing of $6,000-$12,000/month in its own published pricing commentary (firstpagesage.com/seo-blog/geo-aeo-pricing-statistics).
Best for: A firm comfortable hiring the most established AEO/GEO brand in the category, on the understanding that its public case study is a personal-injury practice, which is a different buyer and a different content strategy to corporate counsel.
5. Position Digital
Position Digital is a London agency with a dedicated Generative Engine Optimization service, including a named "GEO Audit" product, and it lists professional services among its served B2B sectors. It names no law-firm client specifically; its own roundup of GEO agencies in fact points legal-sector readers elsewhere. Pricing is not published on its services page, though the site notes a minimum engagement of around $2,000/month.
Best for: A UK-based corporate or professional-services firm wanting a defined GEO audit product from a generalist agency, without a legal case study attached.
6. Blend
Blend (trading as Blend B2B) runs a dedicated AEO services line targeting B2B visibility across ChatGPT, Perplexity, Claude and AI Mode, with published pricing tiers starting at $7,500/month for its Essential AEO package (blendb2b.com/en-us/pricing). Its positioning explicitly includes "professional services and advisory firms," and its closest relevant case study is BCAS, described as "a specialist legal and regulatory consultancy focused on cryptocurrency" (blendb2b.com/work/bcas): legal-adjacent, not a conventional law firm.
Best for: A professional-services or advisory firm that wants published pricing tiers and a legal-adjacent regulatory case study, not a law-firm-specific one.
How does a B2B law firm actually get cited by AI engines?
A B2B law firm gets cited the same way any advisory business does: by being an unambiguous, well-corroborated entity whose named people and specific engagements show up consistently across its own site and third-party sources the engines trust. In the closest measured proxy we have, private equity and M&A deal sourcing, vendor and agency sites carried 85.0% of citations and no single third-party source type dominated behind them; social and video led at only 10.2% (what AI engines cite, by industry). The practical read for a law firm: your own site has to carry the specific, checkable detail (named partners, practice areas, representative matters), because the engines are not finding that detail anywhere else in volume.
How to choose an AEO agency for a B2B law firm
- 1. Separate corporate proof from consumer proof. A personal-injury or immigration case study tells you little about whether an agency can get a mergers-and-acquisitions or regulatory practice cited; ask for the closest match to your actual practice areas.
- 2. Ask what gets measured, and how often. A one-time audit is a starting point, not a programme; ask whether citation tracking repeats on a schedule across the engines your buyers actually use.
- 3. Get the price before the pitch. Several of the providers above publish nothing; get a number in writing before a discovery call, not after it.
- 4. Check the content plan against compliance. Legal marketing has rules generalist AEO agencies may not know; ask how they handle attorney advertising review before anything publishes.
- 5. Start with a baseline. Run a free AI visibility score or a paid audit before signing anything longer, so "it's working" has a number behind it.
Frequently asked questions
What is AEO for a B2B law firm?
AEO, Answer Engine Optimisation, is the practice of getting a law firm named when AI engines such as ChatGPT or Google AI Overviews answer a buyer's question about who to hire for a specific kind of legal matter, rather than only ranking the firm's website in a traditional search results page.
Is a personal-injury AEO case study relevant to a corporate law firm?
Not directly. Personal-injury and consumer-law buyers ask different questions, read different content and are swayed by different signals than a general counsel or deal team choosing corporate or transactional representation, so an agency's proof in one area says little about the other.
Do AI engines recommend law firms the way they recommend M&A advisors or accountants?
We have not measured law firms directly, but the nearest trust-led, people-not-product category we have measured, sell-side M&A advisors, shows a long tail with no dominant incumbent, which is the pattern a corporate law practice should expect to compete inside rather than a single entrenched leader.
Should a corporate law firm hire a generalist AEO agency or a law-only specialist?
Either can work; the deciding factor is proof. A law-only specialist with named corporate or commercial clients is the stronger default, but a generalist agency with a transparent methodology and relevant professional-services experience is a reasonable second choice if no law-only option fits your budget or practice area.
How much does AEO cost for a law firm?
Published pricing on this list ranges from roughly $997 a month for SourceRank AI's entry plan to $7,500 a month and up for Blend's Essential tier, with several providers declining to publish a number at all; always get a figure in writing before committing.
How long does it take for a law firm to show up in AI answers?
Expect weeks for mechanical fixes like schema and entity consistency to register, and one to two months of sustained content and citation work before a fixed set of buyer questions shows the firm named consistently, broadly in line with how long AEO takes to work for other B2B categories.
Which AI engines should a law firm track first?
Start with ChatGPT and Google AI Overviews, since they carry the most B2B research traffic today, then add Gemini and Microsoft Copilot. Perplexity sits outside the five engines SourceRank AI measures; see our earlier ChatGPT vs Perplexity B2B citation comparison if Perplexity also matters to your buyers.
Does SourceRank AI work with law firms directly?
Yes. SourceRank AI runs the same five-engine measurement and fix programme for law firms that it runs for other professional-services categories; contact us to see a sample citation report before committing to a plan.
