Best GEO Agencies 2026: 11 Generative Engine Optimisation Specialists Compared

By Matt Emgi · Updated November 2026

Nearly three quarters of B2B software buyers now use ChatGPT to evaluate vendors, and 51% of tech brands have zero AI citations to show for it (MarketScale, 2026). Generative engine optimisation (GEO) is the work of closing that gap, and dozens of agencies now sell it. This list compares the 11 best, with pricing checked against each agency’s own published pages in October and November 2026.

Full disclosure before you read: I run EMGI Group, which appears first on this list. Our entry is written as a pitch with receipts, every other entry is sourced from at least two independent references, and the caveats their sales pages leave out are stated plainly. If what you actually need is a full search partner for the AI era rather than a GEO specialist, start with the companion list of the best AI SEO agencies.

The 11 best GEO agencies at a glance

How this list was evaluated

• A real citation mechanism, explained plainly. If an agency cannot tell you how AI engines pick their sources, it cannot change which sources get picked.
• Off-site work in the delivery, not the appendix. AI answers lean heavily on third-party pages and communities. A 5W Public Relations synthesis of nine citation datasets found Wikipedia and Reddit alone drive over a quarter of US ChatGPT citations. Agencies that only edit your website are working on a minority of the machine.
• Named clients and named numbers. This young market is thick with anonymous multipliers. Agencies with checkable results get credit for it below.
• Monthly measurement, not one-off audits. AI Overview trigger rates swung from 6.5% to 24.6% and back to 15.7% within a year (Semrush, 10 million keywords). A snapshot audit ages in weeks.
• Priced like a service, not a secret. Where an agency publishes pricing, it is quoted here from its own pages, checked 30 October 2026.
• Visible in AI answers themselves. The product should work on its maker.

The 11 best GEO agencies in 2026

1. EMGI Group: best for B2B SaaS that wants Google and AI search moved together

HQ: London, UK · Pricing: from $4,000/mo, three-month rolling cycles · Best for: post-PMF B2B SaaS, $1M to $30M ARR

EMGI is my agency, so read this entry as a pitch with receipts. We work on one principle: citations follow authority. AI engines recommend the brands they keep meeting on credible pages, so we put clients on those pages, then keep the signals consistent everywhere the models look. The work runs as one programme through our LLM SEO service for SaaS.

Key services:

• Editorial link building: DR60+ placements with real organic traffic, mapped to the specific pages that drive revenue.
• Listicle and brand mention placements: presence in the third-party lists and comparison pages AI engines cite when buyers ask for recommendations.
• Community and entity work: presence where the engines quote, and consistent brand facts everywhere they learn.
• Prompt-level reporting: monthly re-runs of your buyers’ actual prompts across ChatGPT, Perplexity and Google’s AI, against a recorded baseline.

Why EMGI stands out: the method is published, not claimed. Our research includes a citation gap study across 150 SaaS companies, an llms.txt adoption study across 3,254 SaaS sites and an open capture of the hidden queries behind SaaS buying prompts. The results pages to check: the allied health SaaS campaign, which took over the AI answers for a practice management category, and the web scraping SaaS engagement in a developer-tools market.

Honest caveat: B2B SaaS only, and you get me rather than an account team. Enterprises wanting armies, or brands outside software, should read on.

2. Breaking B2B: best for bottom-funnel comparison queries

HQ: UK · Founder: Sam Dunning · Pricing: Light from $4,600/mo (12-month term); tiers $6,000 to $15,200; Category King from $20,000 · Best for: B2B SaaS with $50k+ ACV that needs decision-stage visibility fast

Breaking B2B does one thing with unusual focus: 90-day pushes on the decision-stage and comparison queries where AI answers directly shape shortlists. Alternatives pages, comparison pages, money keywords, measured in revenue terms rather than traffic.

Behind the agency sits one of the strongest founder media engines in B2B marketing: a top 2.5% podcast past 430 episodes, a daily newsletter and an active YouTube channel. That constant circulation is a genuine GEO asset in its own right, because it keeps the brand appearing in exactly the sources AI models learn from. Named clients include RB2B, Chili Piper and ClickHouse, and the named proof point is Proposify’s 91% increase in AI search traffic.

Key services:

• 90-day BOFU campaigns: alternatives, comparison and pricing queries where buyers decide.
• SEO and AEO together: pages built to rank in Google and be cited in AI answers at the same time.
• Published tiered pricing: six named tiers from Light to Category King, six or twelve-month terms, roughly $500/mo off for the longer commitment.

Why Breaking B2B stands out: it is the clearest pick when the revenue sits in comparison and alternatives queries, and six published pricing tiers mean you know the cost of each step up before the first call.

Honest caveat: the founder is the engine, so founder dependency is high, and the editorial link layer that citations lean on still has to come from somewhere.

3. Nine Peaks Media: best for B2B SaaS and technology companies that want SEO and AI search visibility together

Global: Remote · Pricing: published AI SEO investment range of $3,500 to $10,000 per month · Best for: B2B SaaS, software, IT and technology companies

Nine Peaks Media is a B2B SEO and AI search optimisation agency serving clients across global markets. Its approach combines traditional SEO with generative engine optimisation (GEO), improving visibility in both Google search results and AI-generated recommendations. Since 2009 it has worked with more than 60 brands, including DataDome, Pythian and Moosend.

Nine Peaks Media approaches GEO through a combination of website optimisation, content improvements and external authority building. Instead of focusing only on keyword rankings, the agency also considers how brands appear in AI-generated answers across platforms such as ChatGPT, Perplexity, Gemini, Claude and Google AI Overviews.

Key services:

• Technical SEO: structure, crawlability, indexing and on-page improvements.
• AI-focused content optimisation: making brand information more relevant and accessible to generative search platforms.
• Link building: contextual backlinks and relevant editorial placements.
• Third-party brand mentions: listicle placements, directories and external citations.
• AI visibility optimisation: prompt research and monitoring of how the brand appears in AI-generated responses.
• SEO and GEO integration: conventional SEO and AI search optimisation run as one organic growth strategy.

Why Nine Peaks Media stands out: its approach connects established B2B SEO and link-building practices with newer GEO strategies, strengthening traditional search presence and AI visibility at the same time.

Honest caveat: Companies looking for a GEO-only consultancy should clarify how much of the engagement is dedicated to AI visibility rather than traditional SEO, content and link building. Typical engagements also run 6 to 18 months, a longer-term commitment than some options here.

4. Skale: best for AI citation outreach for scaling SaaS

HQ: London, UK · Founded: 2020 · Pricing: not published; their own listing cites from about $4,000/mo, third-party reviews report $8,000+ floors · Best for: Series A and B SaaS scaling organic into MRR

Skale built its name on SaaS SEO that reports in signups, trials and MRR rather than sessions, with a client roster to match: HubSpot, UserTesting, Maze, Flodesk and Attest. The published outcomes are among the strongest in SaaS SEO: Rezi +176% revenue, Holded +450% signups, Flodesk +2,300% trials.

The GEO offer extends that machine into AI citation outreach: placing and optimising the third-party mentions that drive AI answer coverage. Their named movement is a client’s AI brand coverage going from 22% to 55%.

Key services:

• AI citation outreach: building presence in the pages and lists AI engines cite for your category.
• Revenue-attributed SEO: the established practice: strategy, content and links reported against signups and MRR.
• Link building: manual outreach with the same quality framing as the SEO work.

Why Skale stands out: its SaaS client roster and published revenue outcomes are among the strongest on this list, so the GEO offer is built on an SEO practice with a proven commercial record.

Honest caveat: the GEO practice is visibly newer than the SEO practice, and the pricing picture is murky from the outside. Probe the AI-specific delivery and the real floor on the call before you anchor on any number.

5. First Page Sage: best for regulated, considered-purchase enterprise

HQ: California, US · Founded: 2009 · Founder: Evan Bailyn · Pricing: $6,000 to $12,000/mo, month-to-month, per their own published 2026 pricing report · Best for: healthcare, financial services and other slow-trust enterprise categories

First Page Sage, founded by Evan Bailyn, runs GEO on executive thought leadership: long-form expert content under named executives, built for industries where buyers research for months and trust is the product.

Named clients include Salesforce, Logitech, Verizon, U.S. Bancorp and Dignity Health, and they are one of the few agencies publishing their own GEO research and pricing data rather than hiding both.

Key services:

• Thought leadership content: executive-bylined articles targeting the questions AI engines answer in regulated categories.
• Generative engine optimisation: adapting that expert content to the questions buyers put to ChatGPT, Perplexity and Google’s AI answers.
• Published benchmarks: pricing studies, CAC benchmarks and agency rankings for the whole category.

Why First Page Sage stands out: month-to-month terms are rare at this price point, and few agencies show their working on pricing and benchmarks this openly.

Honest caveat: their best-known evidence is self-published, and their own agency ranking puts First Page Sage first. Verify the claims with named references in your industry.

6. Omniscient Digital: best for GEO tied to pipeline for funded SaaS

HQ: Austin, US · Founded: 2019 · Pricing: from about $120,000/yr ($10,000/mo) · Best for: Series A to C B2B SaaS with content as the main engine

Omniscient Digital was co-founded by David Ly Khim, Alex Birkett and Allie Konchar, who came out of growth and content roles at HubSpot and Shopify, and it shows: revenue framing, documented frameworks and a client roster (Jasper, Asana, Loom, SAP, Hotjar) as SaaS-credible as any on this list.

Their GEO work grew out of their own AI citation research rather than a rebrand. The named proof is Convert growing AI citations 140% and LLM visibility 81% in 60 days, and OnBoard reaching the top spot for AI search visibility with an 88% lift.

Key services:

• Content-led GEO: strategic content built to be cited in AI answers as well as rank.
• Barbell content strategy: mostly product-led conversion content with a smaller share of attention-earning assets, typically around 90/10.
• SEO and technical foundations: full-stack organic for software companies.

Why Omniscient stands out: results are reported in pipeline terms, such as $400,000 of qualified pipeline for Teambridge, rather than in traffic alone.

Honest caveat: content is the engine and off-site authority is not the core muscle. The $10,000/mo floor prices out earlier-stage teams.

7. Discovered Labs: best GEO-native boutique

HQ: London, UK · Founded: 2024 · Pricing: from €6,995/mo on a six-month term (€7,995 month-to-month); Compete tier €10,995/mo; top tier from €15,995/mo · Audit: €4,370 one-off, fully credited to your first retainer month if you sign within 14 days · Best for: teams that want a GEO-native specialist rather than a converted SEO shop

Discovered Labs is one of the few agencies born for this market rather than converted to it. Co-founders Liam Dunne, whose bio credits him with taking Instantly.ai to $20M ARR, and Ben Moore, a former Stanford AI researcher, built delivery around a structured content framework (CITABLE) and measurement around their own AI Visibility Tracker.

The named proof: Gladia’s sales-accepted leads up at least 7x, Granola’s AI citation rate up 558% and incident.io up 22% in meetings booked. The standalone diagnostic is a sensible low-risk way to test them: it is fully credited against your first month if you proceed.

Key services:

• CITABLE framework delivery: a documented, repeatable GEO methodology rather than ad hoc tactics.
• Proprietary visibility tracking: daily tracking of where the brand appears in AI answers, across every major model.
• Tiered retainers: three published tiers so you know the scope jump before the sales call.

Why Discovered Labs stands out: it is the most GEO-native team on this list, with measurement built in-house rather than rented from a third-party tool.

Honest caveat: founded in 2024, so a short track record and boutique capacity. That is the trade for genuine specialists.

8. Optimist: best for a transparent, low-commitment start

HQ: Des Moines, US · Founded: 2016 · Founder: Tyler Hakes · Pricing: from a published $3,000/mo, with weekly AI visibility tracking and a shared Slack channel · Best for: teams that distrust this category and want to start small and visible

Optimist, founded by Tyler Hakes in 2016, publishes the lowest entry price on this list directly on its site, and backs it with a client list that proves it is not a discount shop: Semrush and Superhuman on the homepage, Stampli, Glide, Kubera and Plytix in the case studies.

Named outcomes include a 5x inbound SEO pipeline for Stampli, 14x leads attributed to content for Glide and a 4,200% lift in product sign-ups for Kubera. A free strategy call with the founder makes the first conversation genuinely free.

Key services:

• GEO retainers from $3,000/mo: published on the page, no call required to learn the floor.
• Weekly AI visibility tracking: a reporting cadence most of the market only offers monthly.
• Content-led execution: the established Optimist content practice pointed at AI answers.

Why Optimist stands out: pricing, reporting cadence and the founder are all visible before you commit, which is rare in a category this opaque.

Honest caveat: boutique scale, and their own best-GEO-agency ranking puts themselves first, which is the market’s bad habit even among its most transparent players.

9. Omnius: best for EU SaaS and fintech

HQ: London, UK and Belgrade, Serbia · Pricing: not public · Capacity: eight new clients a year · Best for: European SaaS and fintech brands

Omnius pairs content-led GEO with its own AI visibility software, Atomic AGI, which tracks AI search visibility and source citations alongside the service. The strongest credential is organic: Google’s own AI Overview for this exact query cites Omnius directly, which is the product demonstrating itself in public.

Named fintech and SaaS work includes ANNA Money, where signups grew 60% and AI search traffic 164%, and Myos, up 228% in signups in six months. WorldFirst, TextCortex and AuthoredUp also appear among its clients and testimonials.

Key services:

• Content-led GEO: SaaS and fintech content built for AI citation.
• Atomic AGI tracking: their own software for AI visibility and source citation monitoring, offered alongside the service.
• European market depth: offices in London, Belgrade and Dubai, with native understanding of European SaaS buying and compliance contexts.

Why Omnius stands out: a deliberate cap of eight new clients a year, so senior attention is built into the model rather than promised on a sales call.

Honest caveat: unpublished pricing, and like half this market, some visibility comes from ranking themselves in their own comparison content. Verify with named case studies on the call.

10. iPullRank: best for enterprise technical GEO

HQ: New York, US · Founded: 2014 · Founder: Mike King · Pricing: not public; directory estimates put minimums above $10,000/mo · Best for: enterprises whose GEO problem is architectural

iPullRank, led by founder and CEO Mike King, runs the deepest technical practice in the market: how AI systems retrieve, chunk and rank content, treated as engineering rather than copywriting. For large sites where the problem is that AI engines cannot read or trust the architecture, nobody is more credible.

Their research is the reference material much of this industry quietly works from: The AI Search Manual, their breakdown of how Google’s AI Mode works, and a study of how the same 16,000 users behave in AI search versus Google. Qforia, their free query fan-out simulator, shows the engineering-first approach in practice.

Key services:

• Relevance engineering: restructuring content and architecture around how retrieval systems actually work.
• Enterprise technical SEO: crawlability, structured data and performance at scale.
• AI search research: published, practitioner-grade analysis of generative retrieval.

Why iPullRank stands out: nobody else on this list publishes research this deep on how generative retrieval actually works.

Honest caveat: case studies are deliberately anonymised, so ask for references. And if your GEO gap is off-site presence rather than on-site mechanics, their strength is not your bottleneck.

11. Go Fish Digital: best for patent-level retrieval rigour

HQ: Raleigh, US · Founded: 2005 · Pricing: not public · Best for: regulated and reputation-sensitive brands

Go Fish Digital reads the search patents so you do not have to, then builds tools around them. Barracuda, its AI page-analysis platform, scores content against 14 factors drawn from Google’s own patents, alongside an AI Overview Analyzer and a semantic content audit. Brands including Lowe’s and LegalZoom use Barracuda.

The practice combines technical SEO with digital PR and online reputation management, which matters for brands where being cited wrongly in an AI answer is worse than not being cited at all. Named work includes MoneyGeek, where clicks rose 75%. Go Fish is now part of the Agital group.

Key services:

• Patent-informed GEO: optimisation grounded in how the engines are documented to work.
• Digital PR: earning the third-party coverage AI answers draw from.
• Reputation management: monitoring and correcting how AI systems describe the brand.

Why Go Fish Digital stands out: it has turned patent research into software clients can actually use, rather than a methodology deck.

Honest caveat: for a straightforward SaaS visibility problem, this is a research lab where you may only need a workshop.

Before you trust any list (including this one)

Almost every list ranking GEO agencies is published by a GEO agency that ranks itself first. In October 2026 we asked ChatGPT, with web search on, to name the best GEO agencies. Its number one pick was a firm few practitioners have heard of, and the deciding source was a press release the winner wrote about itself:

Another of the five sources behind that answer was First Page Sage’s own study, which ranks First Page Sage first. To their credit the methodology is published in full, and the same article warns that most GEO rankings lean on pay-to-promote directories. They are right, and the machine retrieved their table anyway.

Google is no cleaner. Its AI Overview assembles a shortlist from the same ecosystem, and page one includes a paid listicle sitting in a regional newspaper:

EMGI did not appear in that ChatGPT answer. The agencies that did were largely there because of pages like the ones above. So run the check yourself, on your own category, before you sign with anybody; here is a screenshot-by-screenshot walkthrough of how.

What is GEO, and how does it work?

Generative engine optimisation is the work of making your brand the one AI engines retrieve, cite and recommend: in ChatGPT answers, Google AI Overviews, Perplexity, Claude and Gemini. When an engine answers a buying question it does two things: it recalls brands it learned about in training, and it runs live searches and merges what it finds. You influence the first by being consistently present on the pages and communities the models learn from, and the second by being on the pages they retrieve: your own site, third-party lists and communities. Google’s AI surfaces quoted Reddit in 81.6% of the SaaS buying queries we measured, which is why a GEO plan that only edits your website is working on a minority of the machine.

The simplest way to hold it: memory is your reputation, retrieval is your references. The full argument, including how GEO relates to SEO and AEO, is in our GEO versus SEO guide.

Agencies, tools, and the hybrids in between

Three different products get sold under “GEO” and buyers keep paying for the wrong one. Pure tools: Profound, AthenaHQ, Peec AI and Otterly track your AI visibility; useful instruments, zero execution. Pure agencies: most of the list above; they do the work and license or build measurement as needed. Hybrids: WebFX (OmniSEO), Graphite, NoGood (Goodie) and Flying Cat (Traqer) sell their own software alongside services, which can be efficient but muddles what your retainer actually buys. The test is one question: “if we cancel, what stops happening?” If the answer is mostly “the dashboard”, you were buying a tool.

Honourable mentions

Siege Media, Animalz and Onely all do work that touches GEO (citation-worthy content assets for the first two, technical retrievability at enterprise scale for Onely) and are covered properly in the companion AI SEO list, where their broader practices belong. Beyond those: Directive Consulting for enterprise B2B demand gen with GEO integrated. Minuttia, a capable content shop whose heavy self-ranking habit means you should verify claims independently. NoGood for consumer and brand-name work (SteelSeries, 23x YoY AI search traffic). Singularity Digital for pre-Series-A SaaS at $1-10M ARR. Victorious and WebFX for enterprises that want AEO inside a generalist system.

Who should NOT hire a GEO agency?

• Skip it if your Google fundamentals are broken. AI engines lean on the same authority signals, and the sequencing matters. Our GEO guide for SaaS covers what comes first.
• Skip it if you cannot commit two quarters. Model memory moves slowly. That is physics, not agency excuses.
• Skip it if you expect guaranteed citations. Nobody controls the models. Anyone promising a specific answer is selling certainty they do not have.

How to pick: a 4-step framework

Step 1: baseline yourself. Ask ChatGPT, Perplexity and Google’s AI your ten most valuable buying questions. Record who appears. This is your scorecard for every sales conversation, and it costs nothing. (The volatile trigger rates on Google’s AI Overviews are exactly why you re-run it monthly.)

Step 2: ask each agency which mechanism they move. Retrieval (live citations), memory (trained associations), or both, and with what deliverables. The answer instantly separates specialists from re-labelled SEO.

Step 3: check the off-site muscle. Ask for three examples of third-party placements they earned that later appeared in AI citations. This is the hardest question on the list, which is why it is the most useful.

Step 4: prefer short commitments and monthly prompt-level reporting. The market is eighteen months old. Anyone demanding a year of your budget before showing movement is transferring their risk to you.

Where does GEO go next?

Three predictions, held loosely. The engines diverge, so single-engine strategies age badly. Monitoring becomes free as visibility dashboards get absorbed into every SEO suite, leaving “who can move the score” as the only paid question. And the citation economy professionalises: the third-party pages that decide AI answers become as contested as page one of Google once was, which makes early authority on them the cheap window worth using.

Frequently asked questions

What does a GEO agency do?

A GEO agency works to get your brand retrieved, cited and recommended by AI engines: ChatGPT, Google AI Overviews, Perplexity, Claude and Gemini. Legitimate delivery spans on-site retrievability, off-site authority (links, mentions, community presence on the sources engines cite), entity consistency, and monthly measurement of how AI answers to your buyers’ prompts change.

How much does GEO cost in 2026?

Published benchmarks, including First Page Sage’s published 2026 pricing research, put entry engagements at $1,500 to $5,000 a month, mid-market at $5,000 to $10,000, and enterprise from $10,000 to $25,000+. One-time audits and roadmaps run roughly $5,000 to $7,500. GEO added onto an existing SEO retainer typically costs an extra $500 to $1,500 a month.

Is GEO different from SEO or AEO?

They overlap heavily and share an authority foundation; the difference is the target surface and the measurement. SEO optimises for ranked links, GEO for being cited and recommended inside generated answers, and AEO (answer engine optimisation) is largely a synonym for GEO that some agencies prefer. Treat vendors that sell them as unrelated disciplines with suspicion.

Did Gartner really predict search volume would drop 25% by 2026?

Yes, in February 2024, and it is worth quoting carefully: it was a prediction, and 2026 retrospectives show traditional search has proven more resilient than that number implied. The genuinely measured shifts are still dramatic: generative AI traffic to US retail sites jumped 1,200% (Adobe Analytics). Build strategy on measurements, not prophecies.

Which AI engine should I optimise for first?

ChatGPT carries the dominant share of AI referral traffic and B2B research usage, so it is the default first target, with Google AI Overviews second because of raw search volume. But citation sources differ by engine (Perplexity leans on YouTube and communities far more, in our own capture), so a serious programme baselines all of them before choosing where to push.

Start with the baseline, not the shortlist

Run your ten buying prompts before you talk to any GEO agency, including us. If you are a B2B SaaS company and the answers came back without you in them, that is fixable, and I will show you how specifically with a free AI visibility audit: your prompts, your competitors, your gap, no obligation. And if what you actually need is the broader church of AI-era SEO rather than a GEO specialist, the companion list linked at the top of this article is the place to start.
