Hiring an LLM SEO agency in 2026 means paying someone to change what ChatGPT, Claude, Gemini and Perplexity say when a buyer asks them for a recommendation in your category. That sounds like one job, but it is really four, and it helps to know which of them you are buying.
The first job is presence in what a model already knows. A model answering from its own weights draws on whatever was written about you, and about your category, across the open web before its training cutoff. Nobody can edit that directly, so the work is slow and indirect: consistent coverage on trusted third-party sites and research that other writers reuse. The second job is retrieval and citation. When an assistant searches the live web before it answers, it pulls a handful of pages from a search index, and the question becomes whether your pages are indexed, crawlable by AI bots, and written so a passage can be lifted cleanly into an answer. The two jobs use different levers and move on different timelines, and our guide on how language models decide who to cite covers the mechanics in detail.
The third job is entity consistency. If your company is described one way on your site, another way on LinkedIn, a third way in directories and a fourth way in old press coverage, a model has to guess which version is true, and it often blends them. Good LLM SEO services start with a single agreed description of who you are, what you sell and who you sell it to, then push that description into schema, profiles and third-party pages. The fourth job is third-party mentions: listicles, comparison pages, community threads and industry publications that an assistant retrieves and trusts more than your own site. This is where LLM SEO overlaps with digital PR, and where the agencies that focus on LLM citation and brand mention building do much of their work.
Finally, you are paying for measurement. Traditional rank tracking does not tell you whether you appear in an AI answer, so a credible LLM SEO company should define a fixed set of buyer prompts, run them across engines on a schedule, and report your share of voice against named competitors, ideally tied to pipeline rather than impressions. Many agencies license AI visibility tracking tools for this; some build their own. The firms below were chosen because LLM optimization, sometimes called LLMO, is a named, documented service on their own websites rather than a line added to an old SEO menu. Each was verified on its own site, and the mix runs from established search firms to boutiques founded around AI visibility.
This list covers agencies that sell LLM SEO as a defined service: making a brand’s own site and content easy for language models to retrieve, understand and cite. For firms that focus on earning mentions on third-party sites, see our roundup of agencies for LLM citation and brand mention building, and for full generative engine optimization programs, see the best GEO agencies.

Best LLM SEO Companies In 2026
1. Found — London Agency With A Named LLM SEO Practice And Luminr Tracking
Found is a London search and performance agency based on Hatton Garden, with a second office in New York. It sits inside Tomorrow Group alongside Braidr, a data and AI consultancy, and it is a Google Premier Partner whose client roster includes Toolstation and PUMA. What earns it the top spot here is that it markets LLM SEO under that exact name, as a defined service with its own scope, rather than folding AI answers into a general SEO retainer.
The service covers semantic content structuring, llms.txt management, entity optimization, prompt-led keyword expansion, FAQ development, a community mentions strategy, and authority building through digital PR. Measurement runs through Luminr, Found’s own platform for seeing how and where AI engines surface a brand across ChatGPT, Claude, Gemini and other assistants, and the work sits within what the agency calls its Everysearch methodology.
Found publishes a case study for Mahlkönig, a commercial coffee grinder maker, reporting a 194 percent year-over-year rise in blog clicks and stating that 67 percent of the brand’s LLM citations came from content the agency created. Found suits mid-market and enterprise brands that want LLM SEO run alongside paid media and digital PR by one team.
2. Breaking B2B — Senior-Led LLM SEO For B2B SaaS Pipeline
Breaking B2B is a UK-based agency founded by Sam Dunning, who also hosts the Breaking B2B podcast. It works only with B2B, SaaS and technology companies, and it states that every account is handled by senior SEOs with no junior hand-offs. Its dedicated LLM SEO page treats search-index SEO and AI citation as one program, on the reasoning that assistants source many answers from what already ranks in Google and Bing.
The service has four parts: money-keyword research and ranking work in the search indexes, what the agency calls brand visibility engineering (placements in sources that models cite, brand mention outreach and entity optimization), reverse-engineering the answer format each model uses for a given query type, and agent-friendly technical SEO.
Published results include Proposify, which reported 91 percent growth in visitors from AI search and a 115 percent lift in demos, and RB2B, which grew non-branded organic traffic by 77 percent. The client list also includes Vidyard, ClickHouse and Ahrefs. Pricing starts at $4,000 per month, with the agency noting average spend of $7,000 or more, on six or twelve month programs. It suits SaaS marketing leaders who want LLM SEO judged on demos rather than visibility scores.
3. DerivateX — Citation Engineering For B2B SaaS At $5M To $50M ARR
DerivateX is a Bengaluru agency founded in January 2024 by Apoorv Sharma, an SEO practitioner since 2018, and Shivanshi Bhatia, a former SaaS founder. It lists LLM SEO as a primary service line, with sub-services for LLM visibility, entity optimization and what it calls Agent Search Optimization, and it deliberately narrows its market to B2B SaaS companies between $5 million and $50 million in annual recurring revenue.
Its LLM SEO scope has six parts: an AI visibility audit across ChatGPT, Perplexity, Gemini and Claude; citation engineering through comparison pages and AI-structured content; third-party placements on industry publications; entity and schema work including knowledge panel optimization and llms.txt; cross-platform measurement tied to pipeline; and ongoing monitoring of shifts in which sources get cited. Work runs in 90-day sprints, and the agency says that if the first sprint does not show clear citation movement, it will not ask the client to continue.
Pricing is published in three retainer tiers of $5,000, $8,000 and $12,000 per month, plus a separate placement budget of $1,000 to $3,000. Case studies include Gumlet, which attributes more than 20 percent of inbound revenue to AI discovery, and REsimpli, which the agency says became the top-cited real estate CRM in ChatGPT within 90 days. It fits funded SaaS companies that want founder-level attention.
4. Techmagnate — Large Indian Search Agency With A Dedicated LLM SEO Line
Techmagnate is a New Delhi digital marketing agency founded in 2006, with offices in Mumbai, Pune, Bangalore and Chennai and a team of more than 300. It is a Google Premier Partner, and its search practice has won awards in the financial services sector. It runs a dedicated LLM SEO services page, and it has gone further than most by splitting out separate Gemini SEO and Perplexity SEO offerings for brands that want to prioritize one engine.
The LLM SEO service covers AI-driven keyword research for conversational queries, content structured for language models, semantic optimization, link building and ongoing analytics. The agency reports that across 103 brands in its 2025 to 2026 financial year, client keywords were cited in AI answers more than 333,000 times, and it reports a 273 percent increase in AI visibility over the same base.
Named clients include Bajaj Finserv, Hero FinCorp and Hyundai. Techmagnate suits large, regulated brands with big keyword sets that want an LLM SEO company with the staff to handle enterprise volume.
5. Netpeak US — LLMO Inside A Multinational Performance Marketing Group
Netpeak US is the American arm of Netpeak Group, an international marketing holding company established in 2009 with more than 600 people and offices in Ukraine, the UK, Bulgaria and Kazakhstan. The US company lists its address in Dover, Delaware. Its service page for generative engine optimization explicitly names LLMO, describing the offer as SEO for AI and LLM optimization under one scope.
Deliverables include a visibility audit across ChatGPT, Gemini and Perplexity, generative keyword research built around the questions people type into AI tools, content structuring for AI answers, a brand mention strategy across owned and external platforms, technical SEO changes for LLM crawler access, and AI channel analytics delivered through custom dashboards. The agency says it has more than 80 SEO specialists and has completed more than 2,100 SEO projects.
The client list is heavy on consumer and ecommerce names, including Domino’s, Puma, Bosch Siemens and Depositphotos. That makes Netpeak US a sensible choice for brands that already buy SEO, PPC and email from a performance agency and want LLMO added by a team with the headcount to run it across many markets.
6. Flow Agency — Berlin B2B Boutique With A Custom LLMO Dashboard
Flow Agency is a B2B marketing boutique headquartered in Berlin and run as a remote team, founded by Viola Eva, who speaks regularly on search. It works with B2B startups, SaaS companies and professional services firms, and says it has helped more than 100 of them grow visibility. Its site uses the term LLMO directly and treats LLM optimization as a core service rather than an add-on, arguing that models recommend brands they already recognize and trust.
The LLMO service is built around quarterly strategy and goal setting, opportunity analysis using AI search tracking, audits of the listicles and reference pages that AI answers pull from, and reporting through what the agency describes as its first-of-its-kind LLMO dashboard. Strategy is tied to the client’s go-to-market plan and messaging.
Named clients include Beekeeper, Betterworks, Simpro, FloQast and Mailbird. Flow is a good match for European or international B2B software companies that want a senior boutique to run SEO and LLMO together, with particular attention to the third-party lists and reference sources that shape AI recommendations.
7. Verticality — Model-By-Model LLM SEO With Published Monthly Pricing
Verticality is a Toronto agency founded by Vadim Litvak that serves clients in Canada and the United States. Its homepage leads with AI search, and its LLM SEO page is one of the more specific in the market. The core argument is that ChatGPT, Perplexity, Google AI Overviews, Gemini, Claude and Microsoft Copilot cite different sources and often disagree, so the work has to be planned engine by engine rather than as one generic AI program.
The service has five deliverables: index gate checks covering Bing and Google indexing, crawler access, CDN settings and sitemaps; an entity sheet that standardizes how the brand is described everywhere; per-engine source mapping that shows which pages each model cites; answer page rewrites plus placements in the sources that are already being cited; and monthly scorecards of mention and citation rates by model. The agency tracks a fixed set of buying questions daily with its own tracker.
Pricing is published at $2,500 to $7,500 per month on month-to-month terms, with no long-term commitment. Client testimonials come from Else Nutrition, Flow Security and Memphis.dev. Verticality suits SaaS, DTC and regulated brands that want transparent pricing and a technical, engine-specific approach.
8. MQL Magnet — LLMO Focused On Training Data Footprint For Enterprise Tech
MQL Magnet is a founder-led California content and marketing services firm founded by Harold Bell, working with B2B software and AI companies. Its client logos and testimonials include AWS, Cisco, Zscaler, Workday and ServiceNow, which reflects its roots in enterprise content: case studies, thought leadership and video for technology marketers.
Its LLMO service stands out for how directly it targets the first of the four jobs described above. Where most agencies concentrate on live retrieval, MQL Magnet frames LLMO around getting brands named by ChatGPT, Claude, Gemini and Perplexity through what those models learn. Deliverables include model presence audits, mention density campaigns, training data footprint expansion, digital PR and syndication on high-trust domains, distinctive point-of-view development, brand association shaping, author entity building and LLM visibility measurement.
The service sits inside what the firm calls its Engine Optimization Matrix, which maps SEO, AEO, GEO and LLMO against five levers: message, schema, authority, distribution and citation. MQL Magnet is best for enterprise and growth-stage tech companies that already produce strong content and want it syndicated and positioned so it shapes how models describe the category over the long run.
9. DoodleWeb — Seattle Web Studio Running Weekly Six-Engine Citation Tests
DoodleWeb is an independently owned web strategy, design and engineering firm founded in 2019 and based in Seattle’s Columbia Tower, with Chandan Sharma as co-founder and lead strategist. It says it has shipped more than 350 projects for over 120 clients in higher education, government, healthcare, ecommerce and SaaS, and it staffs every project with senior people only. AI search optimization is now a prominent part of its offer, and it runs a dedicated LLM SEO agency page.
The LLM SEO program has eight workstreams: prompt mapping, baseline citation tests, crawler access, entity consistency, answer-first rewrites, structured data, alignment of external profiles, and weekly reporting. Testing covers ChatGPT, Google AI Overviews, Gemini, Perplexity, Claude and Microsoft Copilot, each tracked separately because their sources and refresh schedules differ. It says first citation changes usually take 60 to 90 days.
Pricing is published: monthly retainers of $4,000 to $12,000, project sprints of $8,000 to $20,000 over three to five weeks, and enterprise programs from $12,000 to $35,000 a month. DoodleWeb also offers SiteSonar, its own AI visibility and lead capture tool. It is a natural choice when the site itself needs re-engineering for AI crawlers.
10. SEO Discovery — Mohali Agency With A Four-Step LLM Audit Process
SEO Discovery is a digital marketing agency in Mohali, Punjab, founded in 2003, with a team of more than 400 and clients that have included Mercedes-Benz, Toyota and Indiamart. LLM SEO is one of many services on its menu, but it has its own detailed service page and a documented process, which puts it ahead of agencies that only mention AI answers in passing.
The LLM SEO scope includes content written for AI comprehension, entity and knowledge graph optimization, structured data and schema, authority building through citations and thought leadership, AI Overview and featured snippet work, and citation tracking across AI platforms. Engagements follow four steps: an LLM audit that scans six major AI systems, query mapping to find the conversational intent behind buyer questions, content and entity engineering, and continuous monitoring with monthly reporting.
The service page includes anonymized examples, such as an immigration law firm and a DTC wellness brand, rather than named case studies, so ask for references in your sector before signing. SEO Discovery fits companies that want a structured LLM audit and ongoing optimization from an experienced offshore team at a lower cost than a US or UK boutique.
How To Choose An LLM SEO Agency
Which Of The Four Jobs Do You Actually Need?
Start by diagnosing before you shortlist. If assistants never mention you when asked about your category, the gap is usually presence and third-party mentions. If they mention you but describe you wrongly, the gap is entity consistency. If they cite competitors’ pages on queries where your content is stronger, the gap is retrieval: indexing, AI crawler access or passage structure. Ask each agency to show you which of these it sees in your case and to explain how its plan addresses that specific gap, not all four at once.
The best LLM SEO agency for a well-known brand with a messy entity footprint will look very different from the right partner for a new company nobody has written about yet.
How Will They Measure AI Share Of Voice?
Ask for the exact prompt set they will track, how many engines they will cover, how often they will run the prompts, and how they handle the fact that answers vary from one run to the next. A serious proposal names competitors, reports mention rate and citation rate separately, and shows a baseline before any work starts. Be wary of a single blended visibility score with no method behind it. If they rely on third-party software, ask which one and whether you get direct access.
Can They Earn Mentions Beyond Your Own Site?
Most of what shapes an AI recommendation lives on other people’s websites. Ask what share of the budget goes to placements, digital PR, reviews and community work, and ask for examples of third-party pages the agency has influenced that now show up as citations. An agency that only offers on-site rewrites and schema is doing part of the job. Several firms on this list publish a separate placement budget, which is a sign they take this part seriously.
What Does The Contract Commit You To?
LLM optimization results take time, usually months, but that is not a reason to sign a year-long contract blind. Look for a defined pilot or sprint with agreed success criteria, clear ownership of any content and placements, and reporting you can take with you if you leave. Published pricing on this list ranges from $2,500 to more than $12,000 a month, so compare scope carefully rather than headline cost. If you also want broader AI search support, compare these firms with our list of top AI SEO agencies.
Conclusion
Our picks for the Top LLM SEO Companies In 2026 reflect how quickly LLM SEO has moved from a buzzword to a service with a recognizable shape: making sure models can find, retrieve and trust the right description of your company, and proving it with repeatable measurement across engines. The firms above approach that job from different starting points, from Found’s in-house tracking platform and Verticality’s engine-by-engine method to DerivateX’s SaaS pipeline focus and MQL Magnet’s work on training data presence. The right choice depends on whether your gap is presence, retrieval, entity consistency or third-party coverage.
Whichever partner you pick, insist on a baseline, a fixed prompt set and a clear link between AI visibility and revenue. If your firm offers LLM SEO or LLM optimization and belongs in this conversation, you can submit your company for consideration in future updates.
