The 9 Best LLM SEO Agencies for B2B Brands (2027 Guide)

Best LLM SEO agencies: Key takeaways for choosing one

  • Your growth stage should drive the shortlist more than any feature comparison. Lean early-stage teams tend to fit published-tier pricing, teams with an established content engine fit editorial-first programs that fold in GEO, and enterprise brands fit full-service retainers.
  • Citation tracking has to span platforms, not just produce one score. ChatGPT, Perplexity, Gemini, and AI Overviews cite differently, so an agency that can’t break out platform-level data can’t tell you where you’re actually losing ground.
  • Pricing in this category runs from roughly $2,000/month tiered packages to $15,000+/month full-service retainers. Most agencies land somewhere in between depending on scope, so know which model you’re buying before you get a quote.
  • A good onboarding hands you a baseline and a fix list within 30 days. Get in writing that you’ll receive an audit of where your brand appears across AI platforms and a prioritized list of what gets fixed first.

LLM SEO isn’t a brand-new idea anymore. Most B2B teams are way past “What impact will AI search have on clicks?” They’ve landed on a harder question: “We know this matters, but how do we actually move the needle?”

The pressure usually starts at the top. An executive runs a few searches in ChatGPT, notices the brand missing from the answers, and asks Marketing why. Many teams then try an AI visibility tracking tool to start addressing the concern from the powers that be, but aren’t sure what to do with the insights from their tool of choice. (Many dashboards only show where you’re absent but don’t tell you what to fix first.)

That gap is where the best LLM SEO agency for your team earns its fee. A specialist can turn those insights into a prioritized plan, which can reduce the pressure to figure out AI search strategy quickly on your own. We built this list to help you choose one.



Disclosure: This guide is published by Omniscient Digital. We’ve included ourselves because we run GEO engagements daily and know exactly what a rigorous evaluation looks like from the inside. However, every agency on this list was evaluated against the same criteria.

How we evaluated the agencies

These criteria exist to separate a genuine LLM search service from the same old slide deck with new terminology on it. Here’s what we checked for on every agency in this list.

  1. decisions, and other nuances that come with B2B. 
  2. A described approach to AI search—Does the agency explain what the work involves (audits, content, authority-building, technical fixes), instead of just “we do AI SEO too”? Bonus points for agencies that publish proprietary research or educational resources on LLM SEO.
  3. Proof of work—Does the agency have a good track record, preferably with testimonals or detailed case studies related to optimization for AI search?

Overviews of the 9 best GEO and AI search agencies

With those criteria in mind, here’s how the nine agencies on this list actually compare. Each overview covers who it fits, what it does well, what it costs, and the caliber of results it has delivered for past clients.

Omniscient Digital: Best for B2B SEO and GEO that fuels pipeline

GEO Service page for Omniscient Digital—the best B2B LLM SEO agency

Best for: B2B and B2B SaaS companies that want their AI-visibility work integrated with a full content and SEO program. Pipeline attribution included. 

Omniscient Digital is an organic growth agency that helps B2B companies turn SEO, GEO, and content into growth channels. Same as with our other offerings, we treat AI visibility as a revenue channel and aim to make it clear how LLM SEO contributes to pipeline, not just vanity metrics like website traffic. We pair citation engineering and LLM monitoring with editorial-grade content built to earn mentions in AI answers and Google rankings. 

Pros:

  • Our engagements cover competitor and citation analysis, technical GEO implementation, and content production as one program. Monitoring runs on an ongoing basis, catching new LLM mentions as they appear and adjusting strategy accordingly. 
  • Our barbell content strategy combines authority-building editorial content with bottom-funnel pages mapped to buyer intent. We help our clients balance brand credibility-building with tapping into conversion opportunities. 
  • We also offer digital PR, technical SEO, conversion optimization, and more. We’ve delivered for dozens of brands, including Jasper, Convert, Smartling, and AppSumo.

Pricing: Full-service engagements start at $10,000 a month.

Results: Convert grew LLM visibility by 81% and AI citations by 140% within 60 days of signing on with us. Even better, our GEO work helped OnBoard double meetings booked from AI-referred traffic month over month. And that’s in addition to consistently being the #1 most visible brand in its category every month starting from January 2026. 

Omnius: Best for SaaS, fintech, and AI teams wanting a GEO specialist

Website screenshot for Omnius

Best for: SaaS and fintech companies that want a vertically-focused GEO partner with a published list of GEO activities, over a generalist shop.

Omnius is a B2B SEO and GEO agency that works solely with SaaS, fintech, and AI companies, which makes vertical specialization the core of its pitch. Its methodology is built specifically around how SaaS, fintech, and AI buyers evaluate vendors, so that’s a plus if you’d prefer a more specialized vendor with expertise in your industry or vertical.  The agency has teams across London, Dubai, and Belgrade.

  • Omnius’ site lists 20 GEO activities it handles. The agency reaches beyond the website to off-site work such as multi-channel authority building, cross-platform content syndication, and Knowledge Panel management, to name a few. 
  • It also lists AI-engine competitive analysis, fan-out and emerging query mapping, and Bing optimization among its GEO activities.
  • The agency built proprietary tracking technology called Atomic AGI for monitoring AI-search visibility and auditing site performance across engines.

Pricing:  Prospects must contact Omnius for a quote.

Results: AuthoredUp reported 64% higher conversion on a new website and 110% organic growth within 6 months of working with Omnius. 

Flying Cat Marketing: Best for global B2B SaaS teams wanting SEO and GEO run as one integrated program

Website screenshot for Flying Cat Marketing, which is an international LLM SEO agency

Best for: International B2B SaaS teams that want topical authority built once and used to earn both Google rankings and AI citations, not run as two separate programs.

Flying Cat Marketing is a Barcelona-based SEO consultancy for B2B SaaS brands that treats traditional SEO and GEO as one unified discipline. Content built to rank in Google is also built to get cited by tools like ChatGPT and Perplexity, not split into two separate workstreams. That approach fits SaaS teams operating across multiple markets, where a single piece of content needs to perform in Google search and in AI-generated answers at once.

Pros:

  • The agency’s B2B SaaS specialization supports work on technical, product-led, and bottom-funnel topics that require subject-matter depth.
  • Flying Cat Marketing serves a global B2B SaaS client roster, including Hotjar, ActiveCampaign, and Softr. The company is well positioned to drive international organic growth. 
  • Its services are tailored primarily to B2B SaaS companies, so it’s a good option for software brands that need a more specialized partner. 

Pricing: Flying Cat Marketing does publish some figures for its SEO services, but not for LLM SEO specifically. Contact the team for details. 

Results: D2L’s share of tracked AI answers rose from 12% in December 2025 to 33% in September 2026 thanks for Flying Cat Marketing’s help. The company also saw a 73% increase in demo requests from organic search and LLMs.

RevenueZen: Best for GEO built into a demand-gen program

Website screenshot for RevenueZen

Best for: B2B SaaS teams that want GEO delivered as one module inside a broader demand-generation retainer, with published, tiered monthly pricing.

RevenueZen is a B2B SaaS demand-generation agency that folds GEO into a broader organic-growth service. Like most alternatives, it focuses on brand visibility inside AI Overviews, ChatGPT, Gemini, and Perplexity. It frames GEO as additive to SEO, pairing AI-search monitoring with content and digital PR built for AI-source credibility. Its positioning leans toward teams that already think in pipeline terms. 

Pros:

  • RevenueZen tracks referrals from ChatGPT, Perplexity, Gemini, DeepSeek, and Copilot directly through GA4. This is in place of a separate analytics layer bolted onto existing reporting.
  • The agency pairs GEO work with digital PR, building story angles around original data to place clients in expert roundups and credible outlets.
  • It shares its own internal SOPs and documented methods with clients as part of the engagement, where most competitors keep the process opaque.

Pricing: Pricing runs across six published monthly tiers, from $3,000/month for the Foundation package up to $15,000/month for the Total Market package. 

Results: Expensify saw a 358% increase in total AI Overview appearances and a 101% increase in AI-sourced website visitors, both measured over a 5-month engagement.

Animalz: Best for balancing AI visibility with editorial quality

LLM SEO service page for Animalz

Best for: Content-driven brands, SaaS or otherwise, that want AI-search visibility work delivered with the same editorial rigor as their existing content program.

Animalz is a content marketing agency that now offers Answer Engine Optimization alongside its core content work, helping brands earn visibility in AI-powered search tools. Animalz differentiates through editorial-grade content craft paired with citation outreach instead of just technical audits. That editorial lineage carries over directly into its AEO work, so brands already running a content-led SEO program tend to find the transition natural, not a bolt-on service from a different team.

Pros:

  • Animalz runs a standalone AI visibility audit as one of several discrete service categories, alongside citation outreach and measurement and reporting.
  • Reddit community engagement is included as a named channel within its AEO service. This is an advantage since Reddit is a commonly used source in many LLM results. 
  • Its client base is broad and not SaaS-exclusive, including Amplitude, Preply, and Unit21.

Pricing: Contact Animalz for a quote.

Results: For SupportLogic, Animalz built a diversified content program designed to hold up against the AI-search shift triggered by ChatGPT and Google’s AI-generated summaries. It drove 500% qualified organic traffic growth and a 450% increase in keyword footprint over 12 months.

Quoleady: Best for SaaS teams wanting manual LLM prompt testing

Website screenshot for Quoleady

Best for: SaaS teams that want LLM visibility work validated by hands-on prompt testing and backed by outreach for listicle and media placements.

Quoleady is a B2B SaaS content marketing agency that combines traditional SEO with LLM optimization. The goal is, of course, appearing in AI-generated answers across ChatGPT, Gemini, Claude, and Perplexity, alongside standard Google search. Its team manually tests prompts relevant to each client’s audience, a check that goes beyond automated tracking. That matters because an answer can shift with the exact wording a buyer uses, and a fixed list of tracked prompts may miss those variations.

Pros:

  • Quoleady structures the engagement around four pillars—visibility and opportunity audits, on-site technical fixes like llms.txt and schema markup, authority-building distribution, and monthly tracking reports.
  • It uses proprietary and third-party tracking, including a platform called AIScope, to monitor presence in AI-generated responses.
  • Clients typically see initial movement in AI citations and visibility within 1 to 3 months, per the agency’s stated timeline.

Pricing: Though Quoleady’s Clutch profile lists some pricing for content marketing, SEO, and content writing services, you’ll need to contact the agency for GEO-specific pricing details.  

Results: Quoleady’s LLM optimization work earned Expandi the #1 spot in ChatGPT for “LinkedIn automation tools”. Loopy Loyalty also hit #1 in ChatGPT for “digital passes software”. 

Grow and Convert: Best for GEO with an AI visibility tool included

Website screenshot for Grow and Convert's LLM SEO services

Best for: B2B and B2C teams that want a conversion-first GEO engagement, and a built-in AI visibility tool to support attribution from day one.

Grow and Convert is a full-service B2B and B2C content marketing agency whose GEO offering extends its long-standing “conversion content” methodology into generative-engine visibility. The team rightly believes that GEO is a natural extension of customer-research-driven, conversion-first content. It backs that viewpoint with a proprietary tracking tool (Traqer AI) included at no extra cost. 

Pros:

  • Every engagement opens with structured interviews across the client’s own product and sales teams, feeding GEO strategy and topic selection directly from that research.
  • The agency emphasizes attribution. It ties content and GEO work back to specific conversions, rather than treating traffic or rankings as the end goal.
  • All content is written in-house rather than through AI generation. The agency positions human-written work as a differentiator even in a service built around AI-search visibility.

Pricing: The base package starts at $10,000/month and scales up depending on the number of keywords or articles requested.

Results: For Leadfeeder, Grow and Convert’s pain-point SEO content scaled blog-attributed trial signups to more than 225 per month, with organic blog traffic passing 21,000 monthly visitors along the way. Individual posts converted at roughly 10 times the rate of story-based content by comparison.

NoGood: Best for enterprise AEO and full-service growth

Website screenshot for NoGood

Best for: Fortune 100 and category-leading enterprise brands that want AEO run as its own discipline within a broader paid, organic, and creative growth program.

NoGood is an AI-native growth marketing agency serving Fortune 100 brands and high-growth startups across SaaS, B2B, healthcare, fintech, and consumer categories. It delivers paid, organic, creative, and analytics services through dedicated growth squads. Its own framing is explicit: NoGood treats AEO as its own dedicated discipline, not an add-on to SEO. That framing matters most to brands already running full-service growth programs, since AEO here sits alongside paid and creative work, not as a standalone SEO-adjacent add-on.

Pros:

  • NoGood structures AEO around four pillars—intelligence and strategy, content optimization, earned media and citations, and technical infrastructure. 
  • The agency covers all of the most common LLM surfaces, including ChatGPT, Gemini, Perplexity, Google AI Overviews, Claude, and Copilot.
  • Its partner platform Goodie AI offers real-time LLM visibility monitoring and conversion tracking.

Pricing: NoGood publishes an average retainer figure in place of a fixed-package price list. Typical engagements run above $20,000 a month. 

Results: For SteelSeries, a gaming accessories brand, NoGood’s AEO engagement drove a 23x year-over-year increase in AI search traffic and a 27x increase in conversions from AI platforms.

Flow Agency: Best for boutique B2B SaaS brands

Website screenshot for Flow Agency, which offer LLM optimization services

Best for: Boutique B2B SaaS and professional-services firms that want direct senior access and their own AI-search reporting dashboard over layered account management.

Flow Agency is a boutique B2B marketing agency, founded by Viola Eva and run remotely. It’s built around search-driven growth for SaaS and professional-services companies and unifies organic SEO, paid media, and generative engine optimization under one senior-led team. The agency has worked with more than 100 B2B startups and service providers and runs its own ongoing research into AI-powered search, without following a fixed playbook. 

Pros:

  • Flow Agency resets priorities and strategic projects on a quarterly cycle, not a single static plan locked in for the length of the engagement.
  • It also offers a proprietary LLMO dashboard reporting who is finding the client via AI search, what they engage with, and how it converts. The team also audits the specific listicles and reference sources AI search pulls from to help get clients mentioned there.
  • Clients get direct points of contact, with no intermediary account managers between them and the people doing the work.

Pricing: Contact Flow Agency directly for a quote.

Results: Though case studies with measurable outcomes are available at the time of writing, Flow has plenty of excellent testimonials that speak highly of its GEO work. 

For example, one client said: “It was extremely insightful working with Viola, Helene, and their team at Flow Agency. We conducted a project together regarding’s [sic] Wilmac Technologies’ opportunities when it came to SEO and GEO. Viola developed a comprehensive plan where she led the team through an intensive site audit with great recommendations on how we could improve.”

How to evaluate a GEO or AEO agency

The list above is a good starting point to narrow your search. However, there are still pros and cons to weigh to ensure that you’re making an informed decision—no matter what vendor you’re considering. Below are 5 things to look for. 

1. A documented GEO or AEO methodology, not just SEO with AI language added

Plenty of agency homepages mention “AI search” somewhere. Far fewer can point you to a specific, repeatable process for auditing how an LLM currently represents your brand, then closing the gaps.

That distinction matters. GEO work touches different levers than traditional SEO: schema and llms.txt implementation, citation engineering, knowledge-panel optimization. None of that shows up in a standard keyword-and-backlink audit.

Ideally, you can gather info from the website and draft questions about an agency’s approach before a discovery call. Even if not, they walk you through their framework live. If not, and they start talking in generalities, signing on with that agency would be risky.

2. Citation and visibility tracking across multiple AI platforms

A single aggregate “AI visibility score” sounds tidy, but it hides more than it reveals. ChatGPT, Perplexity, Gemini, Google’s AI Overviews, and other LLMs pull from different sources and update on different cycles. Your brand can be gaining ground in one and disappearing from another at the same time.

Agencies worth hiring track and report each platform separately, not as one blended number.

(Along the same lines, an AI visibility tool that breaks results out by platform gives you an early warning when one channel drops, instead of burying it inside a flat monthly average. If you’re considering a tool for tracking how and how often your brand appears in LLMs, pick one that doesn’t bury useful insights within a vague average.)

3. Case studies with named clients and dated, measurable outcomes

A logo wall proves an agency has clients. It doesn’t prove the work was effective. 

What you want instead is a named client, a specific metric, and a timeframe attached to it. Something like a documented case study showing visibility or citation growth over a stated number of weeks. That combination is hard to fake and easy to verify.

4. Reasonable onboarding process and time to first insight

A standard GEO onboarding runs a few weeks. Beware of an agency that says: 

  • “You’ll be onboarded in days.” This likely indicates a rushed and/or surface-level process. A good agency will need time to do deep research and develop a sound LLM SEO strategy tailored to your company’s unique situation. 
  • “Onboarding takes more than a month.” AI search in general and your AI visibility specifically are changing all the time. A program that takes too long to get off the ground not only means missed opportunities, but also increases the chances you’ll waste resources on outdated recommendations. 

Ask what you’ll have in hand at the 30-day mark, in writing, before you sign. You should get a baseline audit of where your brand currently shows up or doesn’t across AI platforms. Your agency partner should also provide a prioritized list of what it plans to fix first.

5. Contract flexibility and minimum commitment length

Minimum terms in this category range from month-to-month to six-month commitments. That spread is wider than it is in most marketing services. Shorter minimums generally signal an agency confident it can show early movement; longer minimums aren’t automatically a red flag, but they deserve a direct question about why.

GEO results can move faster than traditional SEO in some cases. A single content update or schema fix can change how an LLM cites a page within weeks, not the months typical of a Google ranking climb. That makes a rigid long-term lock-in worth scrutinizing.

Find out what happens if you want to leave after 90 days, and get the answer in writing. Once you know what to look for, the next question is what it costs to get it.

How much do LLM SEO agencies cost?

Pricing across this category spans from roughly $2,000/month at the low end to $15,000 or more per month at the high end. The low end is tiered SaaS-focused packages; the high end is full-service enterprise retainers. Where an agency lands in that range depends heavily on scope. A content-only GEO add-on costs far less than a full-service program spanning strategy, technical implementation, and ongoing monitoring.

Three pricing models show up repeatedly across this category:

  • Tiered, published packages tied to content volume or deliverables. 
  • Custom full-service retainers scoped after a discovery call, with no fixed starting figure published.
  • Enterprise average-retainer figures published without a fixed package list, the pattern among agencies serving Fortune 100 clients.

Price alone won’t tell you which of these is the best LLM SEO agency for your situation, though—that comes down to your growth stage.

Strengthen your LLM visibility with the right partner

Your growth stage and current SEO maturity should drive this decision more than any single feature comparison. An early-stage SaaS company with a lean team and a tight budget is generally better served by a tiered, published-pricing agency like Quoleady or RevenueZen. The scope is defined upfront, and there’s less ambiguity in what you’re buying.

A mid-market or growth-stage B2B SaaS company with an established content program is a different case. If you want GEO folded into a broader editorial-first SEO and content program, Omniscient Digital fits that profile. Especially if you’re already running a content engine and want AI visibility layered in, not run as a parallel workstream. Companies at this stage with a strong existing SEO foundation but a narrower need might instead look at a dedicated SEO strategy service paired with a lighter GEO add-on.

Enterprise brands need a different fit. Ones with the budget for a $20,000-plus monthly retainer and a need for full-service execution across paid, organic, and creative channels are the clearest match for an agency like NoGood.

Frequently asked questions about LLM SEO agencies

What is an LLM SEO agency?

An LLM SEO agency helps brands improve how they’re represented, cited, and recommended inside AI-powered answer engines like ChatGPT, Perplexity, Gemini, and Google’s AI Overviews. The work typically spans technical implementation, such as schema markup and llms.txt files, alongside content built specifically to earn citations rather than just search rankings.

Most vendors now offering these services were traditional SEO agencies first, so they now offer both services. After all, the two disciplines share overlapping technical and content foundations.

How is LLM SEO different from traditional SEO?

Traditional SEO optimizes for ranking position in a list of links. LLM SEO optimizes for being cited or summarized inside a generated answer, where there’s no fixed number of “spots” the way there is on a search results page. That shift changes what counts as success—a citation inside an AI Overview matters more here than a top-three ranking alone.

It also changes measurement. SparkToro reported that 68.01% of US Google searches ended without a click between January and April 2026. Visibility inside the answer itself increasingly matters more than the click that used to follow a ranking.

How long does it take to see results from an LLM SEO agency?

Early signals, such as a documented shift in citation frequency for a handful of tracked queries, can show up within 60 to 90 days for agencies with focused, well-scoped engagements. Larger, sustained gains in AI-search traffic and conversions typically take longer to materialize. Based on the case studies referenced throughout this list, that range runs 6 to 12 months.

Timelines vary by starting point. A brand with little to no existing content authority will generally take longer to see AI-citation gains than one with an established editorial footprint the agency can build on.
