The 7 Best GEO Agencies Driving Real Revenue from AI in 2026

Most “best GEO agencies” lists are written by one of the agencies on the list, and the author always ranks themselves first.

Guilty.

But let me just say why we specifically rank Optimist as one of the best generative engine optimization agencies (besides doing it for the algorithms).

I judged every agency here, Optimist included, against the same criteria. 

Does the agency have convincing proof of their work helping improve AI visibility for clients in published case studies?

Ideally, I looked for evidence that they could connect that visibility to actual commercial outcomes – like increased revenue from LLM referral traffic specifically rather than increases in visibility metrics alone. 

I evaluated each agency on publicly available information, verified pricing where it exists, and also took a hard look at the stated methodology and whether they treat GEO and SEO as an integrated methodology or try to sell these services separately.

Of course, I also evaluated their track record, case studies, and reviews.

Quick note on terminology: We use generative engine optimization (GEO), AI SEO, and answer engine optimization (AEO)interchangeably. 

1. Optimist – Best GEO & SEO Agency for B2B SaaS

Website: yesoptimist.com

Best for: B2B technology and SaaS companies looking to grow their GEO (AI visibility) and SEO or startups who need to build an organic engine from scratch.

Pricing: Free analysis to start then one-time upfront roadmap and strategy with month-to-month retainers for ongoing support from $1,500/month.

Notable clients: Semrush, ZoomInfo, Superhuman, HelloSign, Stampli, Glide, Kubera

What we do well: Optimist is an AEO and SEO consultancy for B2B technology companies, and one of the few agencies in this category with published AI search case studies that report revenue rather than visibility scores:

• 49x LLM referral revenue growth over 14 months for a B2B technology client, alongside 26x LLM referral traffic
• 8x LLM conversions in 8 months for a fintech company, with 25x LLM referral traffic over the same period
• 13x LLM-sourced revenue year over year for a retail (B2C/D2C) brand

The full set of published AEO/GEO case studies reports conversions and dollars, which is the bar this list is judged against.

Optimist’s integrated GEO + SEO methodology is called The Complete Organic Revenue Engine (CORE) Framework, which builds one unified dataset and roadmap of every topic a company’s buyers care about and optimizes it through both the search lens and the AI lens.

The CORE Framework aligns GEO work into two related strategies with different levers. 

The primary strategy focuses on earning brand mentions and recommendations, the outcome that moves pipeline when a buyer asks an AI engine “what’s the best X for Y.” That work runs through content gaps, entity disambiguation, and messaging consistency.

The secondary strategy earns citations through content structure, schema, and fan-out query coverage.

Most GEO sellers conflate the two outcomes, but in our work, we’ve found that you need both approaches to fully optimize for visibility and drive measurable growth. 

Underneath the AI work sits a decade of pipeline-measured SEO case studies:

• Stampli grew inbound pipeline 5X with a 400% lift in MQLs
• Glide hit 14x product signups in a year
• Kubera reached 43x product signups in 15 months.
• HelloSign’s inbound engine fueled the growth that led to a $230M acquisition by Dropbox.

Client reviews back up the case studies. “I was impressed by their domain expertise and their outside-the-box thinking around the changing AI-search landscape,” wrote Evan Vuckovic, Director of Growth Marketing at Stampli, in a Clutch review. 

Optimist’s GEO services page covers the foundations of our services, which include AI visibility tracking and measurement, content and technical strategy, forecasting, roadmapping, and content direction. 

Potential limitations: Optimist is a small senior-practitioner team. Companies that want a 500-person agency with account managers and layered process won’t find that model here.

The deepest experience is in B2B technology and SaaS, so consumer brands and non-tech sectors may be a weaker fit. Engagements are built around strategy and senior execution rather than high-volume content production.

2. iPullRank

Website: ipullrank.com

Best for: Enterprises with complex site architectures that need the deepest technical GEO work available.

Pricing: Custom pricing

Notable clients: American Express, Citi, SAP, HSBC, Nordstrom

iPullRank, founded by Mike King in 2014, operates closer to the machinery of AI search than any other agency on this list. King’s “Relevance Engineering” methodology works at the level of embeddings, passage retrieval, and query fan-out, and iPullRank’s public research on how AI systems expand queries is foundational reading for the whole category.

For an enterprise with a sprawling site, an internal SEO team, and technical debt that breaks AI retrieval, iPullRank is one of the few agencies that can operate at that depth. The client roster reflects that.

Potential limitations: The enterprise orientation and unlisted pricing put iPullRank out of reach for some mid-market budgets. iPullRank handles the retrieval mechanics brilliantly. Companies that primarily need messaging and content-gap work may be buying more technical depth than their problem requires.

3. Siege Media

Website: siegemedia.com

Best for: Enterprise brands that want data journalism and digital PR at scale. 

Pricing: From around $11,000/month

Notable clients: Zendesk, The Zebra, Zapier

Siege Media, founded by Ross Hudgens in 2012 and now 100+ people, approaches GEO through the asset class it has always been best at, which is original data content and the earned media it attracts.

Siege Media holds a verified 4.9/5 Clutch rating across 46 reviews, the strongest independently confirmed client record on this list.

Potential limitations: Siege Media’s primary scorecard based on published case studies is estimated traffic value from third-party tools like Ahrefs and links, which are leading indicators rather than pipeline. A CMO who needs AI-sourced revenue reporting will have to build that attribution layer alongside the engagement. Enterprise pricing puts Siege out of range for some earlier-stage companies.

4. Animalz

Website: animalz.co

Best for: Enterprise B2B and SaaS brands that need expert-led thought-leadership content optimized for AI answers.

Pricing: Animalz pricing is reported by third parties at roughly $8,000/month for researched content and around $10,000/month for premium thought leadership including AEO and GEO. Treat those as reported figures, since they aren’t published on Animalz’s own pricing page.

Notable clients: Google, Intercom, GoDaddy, Zendesk, Amplitude, Airtable

Animalz, founded in 2015, runs as an established distributed content agency with a large writer and editor network. It built its name on deep subject-matter content driven by expert and SME interviews, a method it brands “Movement Marketing,” with AEO and GEO woven through alongside survey-driven whitepapers and LinkedIn thought leadership. 

Potential limitations: Animalz is content and editorial-led rather than technical-SEO or pipeline-attribution-led. Historically it’s a content shop that added GEO.

Published outcomes are content metrics rather than revenue. 360Learning’s blog reached 75,877 monthly pageviews in two years, and SupportLogic posted a 500% organic-traffic increase in 12 months. The only public third-party score is a 3.0/5 Glassdoor employer rating from 74 reviews, which reflects employee sentiment rather than client satisfaction, so don’t read it as a measure of client outcomes.

5. Omniscient Digital

Website: beomniscient.com

Best for: B2B SaaS brands that want an editorial-grade content program extended into GEO. 

Pricing: Custom pricing; engagements reportedly start around $10,000/month

Notable clients: SAP, Adobe, Loom, Asana

Omniscient Digital, founded in 2019 and run as a distributed team of 30+, built its reputation on content that reads like industry journalism rather than SEO filler. Most agencies on this list arrived at GEO from technical SEO. Omniscient arrived from editorial craft.

GEO is now a named service line, supported by a partnership with the AI visibility tracker Peec AI. 

Potential limitations: Omniscient’s published results are content- and SEO-attributed. The agency hasn’t yet published a case study reporting AI-sourced revenue or LLM conversion growth. 

6. First Page Sage

Website: firstpagesage.com

Best for: Companies that want thought-leadership-led GEO and operate outside B2B SaaS, including healthcare and professional services.

Pricing: Premium retainers; $10,000+ minimum per its Clutch listing

Notable clients: Salesforce, Verizon, Logitech, NerdWallet

First Page Sage built a dedicated GEO service before the category settled on a name, while most of this list added GEO to an existing playbook. 

The agency launched its GEO service in May 2023 and positions it as the first of its kind, which means First Page Sage has been doing this work since before most buyers had heard the acronym. The model is thought leadership SEO, an authority-content approach based on the idea that expert-driven content is what AI engines prefer to draw from.

Potential limitations: First Page Sage publishes no granular per-client case study reporting AI-attributed revenue, which is a meaningful gap for an agency selling on AI search expertise. There’s no verified Clutch client rating. The vertical spread runs from tech to construction to real estate, and breadth that wide can dilute depth in any single buyer’s category.

7. Skale

Website: skale.so

Best for: B2B SaaS teams looking for support with off-site brand mentions and third-party citations.

Pricing: $8,000–$20,000/month, agency-published

Notable clients: Perkbox, Personio, MoonPay

Skale is a London-based agency that works exclusively with B2B SaaS and frames every engagement around revenue metrics. Skale’s AI Citation Outreach service line reflects a focus on citation outreach and securing third-party mentions.

Potential limitations: Skale’s exclusive SaaS focus means non-SaaS companies aren’t a fit by design. The entry price is the highest among the specialist (non-enterprise) agencies on this list. Independent verification is thin. The 4.9 Clutch rating that appears in third-party roundups couldn’t be confirmed directly, and the founding history is inconsistently documented.

How to Evaluate a GEO Agency

The hard part of hiring a GEO agency isn’t finding one. 

It’s telling a real GEO partner apart from an SEO shop that renamed its services page. 

The discipline is barely two years old, so the fastest way for any agency to “offer GEO” was to relabel what it already sold. According to Conductor’s State of AEO/GEO 2026 report, 94% of CMOs plan to increase AEO and GEO investment this year, which is exactly the demand that makes every content and SEO shop slap “GEO” on its homepage.

A capability claim and an actual capability are not the same thing.

These are the criteria I’d use to close that gap, in order of how much they actually predict results.

Proof of Brand Recommendations, Not Just Citations

A real GEO agency can show a brand getting named and recommended when a buyer asks an engine “what’s the best tool for X,” not just a dashboard where an “AI visibility score” went up. 

When I evaluate a firm’s proof, I want mentions and recommendation data, not just “visibility” or a focus on citations. Answer engine optimization done right makes a clear distinction between these two forms of visibility.

AI engines can cite your blog post as a source and recommend a competitor by name two sentences later.

Citation drives a little traffic.

Recommendations drive real pipeline and revenue.

AEO and SEO Run as One System

The strongest agencies treat AI-answer optimization and traditional search as a single organic strategy, not as a separate discipline you buy à la carte.

Google’s own AI optimization guidance states that optimizing for generative AI search is optimizing for the search experience, and is therefore still SEO. Danny Sullivan put it more bluntly at WordCamp US in August 2025, saying “good SEO is good GEO.” 

(That’s not to say “GEO is just SEO” – it’s definitely not.)

An agency that sells GEO as a standalone product or tactical SEO services like Reddit content or citation outreach is just jumping on the latest fad.

If an agency is pitching GEO as a service that’s disconnected from your search foundation or tells you traditional SEO is dead weight, they’re misreading how the engines work.

SEO is the foundation AEO builds on, and the AEO, GEO, and SEO relationship is worth understanding before you let an agency sell you one without the others.

Pipeline-and-Revenue Measurement, Not Traffic and Scores

A rising AI visibility score can sit right next to a flat pipeline.

Plenty of brands watched a visibility dashboard climb while revenue didn’t move, because being seen by an AI engine and being chosen by a buyer are measured in different columns. Treat “our client’s AI visibility score went up 400%” as an input to interrogate, not a result to celebrate. 

The strongest credibility belongs to agencies with published revenue outcomes.

As a buyer in a competitive GEO evaluation recently told me, what she wanted in priority order was case studies showing results inside ChatGPT first, business results driven through chat second, and everything else third.

She noted those chat-attributed business outcomes are scarce because too many agencies report on “AI visibility” or “AI referrals” with no connection to leads, revenue, or pipeline.

Criterion	What good looks like	Red flag
Recommendations vs. citations	Shows the brand named and recommended in AI answers.	Reports only “AI visibility score” with no recommendation proof
AEO and SEO integration	Runs both as one organic strategy	Sells GEO as a bolt-on, standalone product separate from SEO
Measurement	Pipeline, revenue, signups, SQLs	Stops at traffic, rankings, or visibility scores
Proof	Published, chat-attributed business outcomes	Logos and traffic charts, no revenue attribution
Pricing transparency	Clear model or honest “quoted per engagement”	Vague scope that balloons after signing

GEO Agency vs. Hiring GEO In-House

Hire an agency when you need GEO capability faster than you can build it, and hire in-house when GEO becomes a permanent, full-time function you want to own.

For most B2B teams shopping this list, the honest answer is an agency first, because the discipline is too new and moving too fast for a single in-house hire to have meaningful reps yet.

The market math favors moving quickly.

G2’s Answer Economy 2026 report found that 51% of B2B software buyers now begin research in an AI chatbot more often than Google, up from 29% in April 2025, and that 69% chose a different vendor than they’d initially planned based on AI chatbot guidance.

A single GEO hire ramping for two quarters is two quarters your competitors are getting recommended and you aren’t.

An agency gives you a team that has already run GEO across multiple clients, which matters when the playbook is changing every few months.

An in-house hire gives you dedicated focus and institutional knowledge, but you’re betting one person can stay current on five AI engines while also doing the work.

The pattern I see most often is teams using an agency to build the engine and prove the model, then bringing a coordinator in-house to run the day-to-day once the system is stable. 

The agency builds it; the hire maintains it.

One more practical note: You can likely move fastest if you have a content or marketing team that can ship the work while an agency leads strategy.

The buyers I talk to who get the most from an agency are the ones who can execute internally based on an agency-supplied roadmap and content briefs. 

If you need the agency to do everything including production, you’re buying a more expensive engagement and should price for it.

What GEO Agencies Cost

GEO agency pricing generally runs from around $5,000/month at the low end to $20,000/month and up for premium or enterprise engagements, with most B2B SaaS retainers landing somewhere in the middle.

The wide range reflects how much the scope varies, from content-only programs to full technical-plus-content-plus-digital-PR systems.

The lesson in that spread is to interrogate scope before price. A $6,000/month retainer that earns brand recommendations is cheaper than a $4,000/month retainer that produces a rising visibility score and flat pipeline.

Price the outcome, not the input.

Red Flags When Hiring a GEO Agency

The most expensive mistake in GEO hiring is paying a generic SEO retainer dressed up as a GEO program. Watch for these signals before you sign.

• “GEO” appeared on their site this year with no published AI outcomes behind it. Nearly every content and SEO agency now lists AEO or GEO services. The claim is table stakes; the proof isn’t. If a firm can’t show AEO-specific results from real clients, it’s selling you a label.
• They lead with an “AI visibility score” and can’t connect it to pipeline. A score is an input. Ask what happened to revenue, signups, or demos, and watch whether the answer gets concrete or gets vague.
• They treat GEO as separate from SEO. A firm selling GEO as a disconnected à la carte product, or telling you SEO is dead, is misreading how the engines actually work.
• Vague scope and undefined deliverables. Custom-everything pricing with no clear model is where engagements balloon. A reputable firm can either show a clear model or honestly say it quotes per engagement.

Frequently Asked Questions About GEO Agencies

What is a GEO agency?

A GEO agency is a firm that optimizes a brand’s content and online presence so AI engines like ChatGPT, Perplexity, Gemini, and Google’s AI Overviews mention, recommend, and cite that brand in their answers. Generative engine optimization, or GEO, overlaps heavily with answer engine optimization (AEO) and builds on traditional SEO.

The strongest GEO agencies treat AI-answer visibility and search as a single organic strategy rather than as separate services, because the work that earns a brand recommendation in an AI answer is largely the same work that builds authority in search.

What’s the difference between GEO and SEO?

GEO optimizes for visibility inside AI-generated answers, while SEO optimizes for rankings in traditional search results, but the two are deeply connected rather than separate disciplines. 

Google’s own guidance states that optimizing for generative AI search is still SEO, and the practical reality is that the topical authority and content quality that earn search rankings also earn AI-answer recommendations. Treat GEO as an extension of SEO into AI surfaces, not a replacement for it.

An agency that sells one without the other is misreading how AI engines work.

How much does a GEO agency cost?

GEO agency pricing typically ranges from around $5,000/month to $20,000/month and up, depending on scope. Content-only programs sit at the lower end, while full technical, content, and digital-PR systems for enterprise clients run higher. Several agencies don’t publish pricing at all and quote per engagement, and some, including Optimist, route buyers through a free diagnostic before scoping a number. When you compare quotes, price the outcome rather than the monthly invoice, since a higher retainer that earns brand recommendations can be cheaper per dollar of pipeline than a lower one that only moves a visibility score.

How do I know if a GEO agency is legitimate or just a rebranded SEO shop?

Ask the agency to show a client getting recommended by name in an AI answer, with a business outcome attached, not just a screenshot of a rising “AI visibility score.” Because GEO is barely two years old, the fastest way for any agency to offer it was to relabel existing SEO services, so a real track record of AI-attributed results is the cleanest filter you have. I’d also ask how the firm earns third-party mentions, since 85% of brand mentions in AI answers come from sources the brand doesn’t own, and an agency that only talks about your website is solving a fraction of the problem.

Should I hire a GEO agency or build GEO in-house?

Hire an agency first if you need GEO capability faster than you can build it, which describes most B2B teams right now. Bring it in-house once GEO is a stable, permanent function you want to own. The discipline is changing every few months, so an agency that has run GEO across multiple clients carries reps a single new hire can’t match yet. A common pattern is using an agency to build the engine and prove the model, then hiring a coordinator internally to maintain the system once it’s running. Teams that can execute briefs internally tend to get the most from the agency model.

Does a GEO agency replace my SEO agency?

In most cases a GEO agency should absorb or integrate with SEO rather than run alongside a separate SEO vendor, because the two functions overlap heavily and splitting them creates conflicting strategies. The strongest firms run AEO and SEO as one system, so hiring a separate GEO shop on top of an existing SEO retainer often means paying two agencies to do overlapping and sometimes contradictory work. If your current SEO agency can’t show real AI-answer outcomes, the cleaner move is usually one partner that does both rather than two that each do half.
