Top 7 Generative Engine Optimization (GEO) Agencies (2026)

Every SEO agency in the world added “GEO” to their website in 2025. We can’t blame them… the demand is real, and the window to claim authority in a new discipline doesn’t stay open forever. But adding a service page and actually knowing how to get a brand cited in ChatGPT, Perplexity, or Google’s AI Overviews are two very different things.

The distinction matters because the stakes are higher than they look. Buyers arriving via an AI recommendation have already received an answer: they’re clicking for validation, not discovery. When AI omits your brand from a relevant response, a competitor fills that slot by default, quietly, and often before anyone on your team notices the gap.

Generative Engine Optimization (lovingly known as GEO) is the practice of ensuring your brand shows up in those answers. It pulls from SEO fundamentals: topical authority, structured data, crawlability, but the goal isn’t rankings. It’s citations. It’s share of voice across AI platforms. It’s showing up when someone asks ChatGPT to recommend a tool, a vendor, or a solution in your category.

The agencies that do this well have built their methodology around how LLMs retrieve and evaluate information. 

What Is Generative Engine Optimization (GEO)?

Generative Engine Optimization (GEO) is the practice of optimizing your brand’s content, structure, and authority so that AI search platforms (like ChatGPT, Google AI Overviews, Perplexity, Gemini, and Claude) recognize, trust, and cite you in the answers they generate.

You may have also heard it be called AEO (Answer Engine Optimization), LLMO (LLM Optimization), or even AIO or AISEO; needless to say, the terminology isn’t fully standardized, but the goal is the same: be present where AI discovery is happening.

GEO vs. SEO: Same Foundation, Different Game

GEO didn’t replace SEO; it extended it. Technical fundamentals still matter: crawlability, structured data, topical authority, and strong content. Research shows that 38% of AI Overview citations come from pages already ranking in Google’s top 10, so there’s a chance that if your SEO is broken, your GEO is, too.

But where SEO optimizes for ranking, GEO optimizes for citation. Where SEO measures clicks and positions, GEO measures share of voice across AI platforms.

A brand can hold the #1 organic spot for a high-intent keyword and still be completely absent from the AI Overview sitting above it. That’s the gap that GEO closes.

Why GEO Matters Now

AI traffic is growing fast, and early data suggests it converts at 2-3x the rate of traditional organic channels, likely because that buyers arriving via an AI recommendation are already further along in their decision. When AI omits your brand from a relevant answer, a competitor fills that space by default.

It’s an influence gap that compounds quietly until it shows up in the pipeline.

GEO is how brands stay in the conversation as that discovery layer continues to shift.

Why Finding the Right GEO Agency Matters

GEO is still technically an emerging field, and the agency market reflects that. In 2025, practically every SEO shop added a “/geo” page to their website. Conference talks pivoted from “how to rank on Google” to “how to show up in ChatGPT.” However, the problem with that is the fact that most of them just repackaged existing SEO services and hoped nobody would notice.

There’s a real discipline here, one that requires understanding how LLMs retrieve and cite information, why entity corroboration across multiple platforms matters more than keyword density, and how to measure visibility that doesn’t show up in Google Search Console. The agencies that get results have rebuilt their methodology around that. The ones that don’t are selling you SEO with a new label.

Here’s what to look for when evaluating a GEO partner:

• Demonstrated results, not just capabilities. Ask for case studies showing improved brand mentions in ChatGPT, Claude, or Perplexity, not just organic traffic wins.
• Proprietary measurement. If an agency can’t show you share of voice across AI platforms, they can’t prove GEO is working. Look for agencies with purpose-built tracking tools or clear partnerships with AI visibility platforms.
• A full-funnel approach. Effective GEO spans technical SEO, content strategy, and digital authority building (think: earned media, citations, structured data). Agencies that only pull one lever won’t move the needle.
• Honest fit assessment. The best GEO agency for a B2B SaaS company looks very different from the right partner for an eCommerce brand. Vertical expertise and business model fit matter.
• Transparency on timeline. GEO compounds over time. Be skeptical of anyone promising fast results, and ask specifically what “success” looks like at 90 days versus 6 months.

The list below is built around agencies that clear these bars, not just ones that showed up in the right roundups.

Our Evaluation Methodology

GEO is still a field where “we do that, too” gets added to agency websites faster than it gets added to actual service deliverables. So rather than pulling together a roundup of whoever ranks for “GEO agency,” we evaluated agencies against five criteria that actually reflect what it takes to move the needle on AI visibility:

• GEO or AEO methodology depth. Does the agency have a documented, coherent approach to AI search optimization, or did they just add GEO to their SEO deck? We looked for evidence of prompt-level thinking, entity optimization, content structuring for AI retrieval, and an understanding of how LLMs actually source and surface information.
• Tracking. If an agency can’t show you where your brand is appearing in AI answers, they can’t prove GEO is working. We prioritized agencies with purpose-built measurement infrastructure, whether that’s a proprietary AI visibility platform, share-of-model dashboards, or meaningful integrations with third-party tracking tools.
• Notable clients and case studies. We looked for demonstrated results, not just capabilities. That means real clients, real outcomes, and where possible, GEO-specific evidence rather than general SEO wins repackaged with new terminology.
• Industries served. The right GEO agency for an enterprise healthcare brand looks very different from the right partner for a B2B SaaS startup. We factored in vertical expertise and business model fit, and called those out explicitly in each profile.

Quick-Reference Comparison Chart for GEO Agencies

The Top 7 GEO Agencies for 2026

NoGood: Best Overall GEO Agency

Best For: Brands that want GEO embedded in a full-funnel growth strategy instead of bolted on as an afterthought.

NoGood is a full-service growth marketing agency that has built AI search into the connective tissue of how it operates, not just as a separate service line, but as a strategic layer that runs through content, social, PR, and performance. Where most agencies treat GEO as a content or technical SEO problem, NoGood approaches it as an owned, earned, and operated media challenge: ensuring that a brand’s signals are consistent and credible across every source LLMs pull from when forming an answer.

In practice, that means GEO strategy at NoGood coordinates across disciplines that most agencies keep siloed. Content teams optimize for AI citability. Social builds brand presence on the platforms LLMs increasingly reference. PR and digital authority work strengthen the third-party signals that AI systems use to validate brand credibility. The result is a compounding visibility strategy.

GEO work at NoGood starts with an LLM visibility audit and prompt-gap analysis, reverse-engineering the questions people are asking AI platforms to identify which answers a brand should be owning, and builds from there into technical optimization, schema implementation, and AI-readable content.

Because GEO is embedded in a broader growth offering that includes SEO, paid media, CRO, and content marketing, visibility improvements connect directly to the pipeline, not just citation counts.

Graphite: AEO-Focused Growth for B2B SaaS & Consumer Tech

Best For: B2B SaaS and high-growth tech companies that want AEO treated as a core growth channel, built on research and proprietary tooling.

Graphite is one of the more recognized names in the AEO space, and notably, CEO Ethan Smith prefers “AEO” over “GEO” by design. His argument? “GEO” already carries a geographic meaning in most LLMs’ training data, creating semantic confusion. It’s a small distinction that says something larger about how deeply Graphite thinks about how language models actually process information.

Smith has 18 years of SEO experience and has become one of the most cited voices in the AEO conversation, including a widely-shared appearance on Lenny’s Podcast, where he outlined how ChatGPT traffic converts 6x better than Google search.

That thought leadership isn’t just for optics; it shapes how the agency operates. Graphite’s methodology is built around identifying the 5% of work that drives the majority of impact, which in practice means intent-based question mapping, persona alignment, and content engineered specifically for how AI platforms retrieve answers.

Their proprietary AEO tracking platform monitors share of voice across ChatGPT, Perplexity, Google AI Overviews, Gemini, and Claude, giving clients visibility into where they’re being cited and where gaps exist. The agency has grown to over 130 people and works with some of the most recognizable names in consumer tech.

Founded: 2020

Headquarters: San Francisco, CA

GEO Case Studies: No GEO-specific case studies (yet), but you can view their SEO work here.

First Page Sage: Long-Term B2B Thought Leadership & Lead Generation

Best For: Complex B2B verticals (SaaS, MedTech, Healthcare, Financial Services, Manufacturing) that need long-term thought leadership paired with GEO.

First Page Sage was one of the first to formally define and offer GEO as a service. In 2023, the agency conducted a large-scale study analyzing the recommendation algorithms used by ChatGPT, Perplexity, and Claude, research that has since shaped how the broader industry thinks about AI visibility. CEO Evan Bailyn lectures on GEO at Stanford and the Haas School of Business, and is a bestselling author on SEO strategy.

First Page Sage’s GEO methodology is built on 15+ years of studying how algorithms surface content, translated into an approach that combines technical AI crawler optimization, thought leadership content engineered to earn AI citations, and reputation signals that build the trust generative engines require before recommending a brand.

All of their 2026 client campaigns include GEO as a standard component alongside SEO.

Their sweet spot is complex, long-cycle B2B categories where authority and trust signals carry more weight than volume. They’re less suited for brands that need fast results or high-volume content at scale.

Founded: 2009

Headquarters: San Francisco, CA 

Team Size: 51-200 employees

Additional Services: SEO, Digital PR, Online Reputation Management, Paid Search, Paid Social, Social Commerce, CRO, Brand Strategy, Web Design & Development, Email Marketing

Industries Served: Saas, MedTech, Healthcare, Financial Services, Manufacturing

GEO Case Studies: No GEO studies specifically, but there are case studies for other services here.

Go Fish Digital: Technical GEO With Digital PR

Best for: Mid-to-large brands that want a single partner for both paid and organic media, particularly eCommerce brands. 

Go Fish Digital leans more technical than other agencies on this list, and relies on Barracuda for their GEO strategy. Barracuda is their proprietary AI platform built in-house by Co-Founder and Chief Product & AI Officer Dan Hinckley. Barracuda evaluates content performance in AI search and is complemented by a Semantic Content Audit tool and an AI Overview Analyzer, giving the agency a research-backed, data-heavy approach to GEO that goes well beyond content optimization checklists.

What makes Go Fish particularly interesting for GEO is the combination of that technical infrastructure with a digital PR capability. Earned media is increasingly one of the strongest citation signals for LLMs, and AI engines tend to pull from sources with third-party validation.

Their SVP of Owned Media leads SEO, digital PR, copywriting, ORM, and email marketing as a unified function, which is a structural setup that maps well to how GEO actually works.

Founded: 2005

Headquarters: Raleigh, NC

Team Size: 201-500 employees

Additional Services: SEO, Digital PR, Online Reputation Management, Paid Search, Paid Social, CRO, Brand Strategy, Web Design & Development, Email Marketing

Industries Served: eCommerce, SaaS, B2B, Healthcare, Finance, Education, Automotive, Real Estate, and Hospitality

GEO Case Studies: MoneyGeek and other service case studies can be found here.

Animalz: B2B SaaS Editorial Authority

Best For: B2B SaaS brands competing on thought leadership and editorial authority.

Animalz is, by reputation, the content agency that other content agencies benchmark against. Founded in 2015, they’ve built editorial programs for companies like Google, Airtable, Atlassian, Wistia, Intercom, and Amazon, an alumni list that signals their quality standard.

Their entry into AEO acts as an organic extension of what Animalz has always done: produce content that earns authority rather than gaming for it. Their AEO process starts with an LLM visibility audit that maps current AI citations across ChatGPT, Perplexity, Google AI Overviews, and Gemini, then translates those gaps into a 90-day execution roadmap. From there, it’s the same editorial rigor applied to a new distribution reality: deep interviews with subject matter experts, micro-refreshes of existing content, citation outreach, and coverage of the specific prompts that matter to each client’s buyers.

What makes Animalz a strong GEO partner is the same thing that makes them a strong content partner: they understand that AI systems favor content that reflects genuine expertise and original perspective. The agencies that just produce “AI-optimized” content at volume aren’t going to win citations from platforms that are increasingly sophisticated about sourcing. Animalz wins on the content quality side of the equation.

Founded: 2015

Headquarters: New York City, NY

Team Size: 51-200 employees

Additional Services: SEO Consulting, Editorial Strategy, Content Systems, Thought Leadership, LinkedIn Thought Leadership

Industries Served: B2B SaaS, Enterprise Tech, VC-Backed Startups

Case Studies: SupportLogic and other service case studies can be found here.

Brafton: Content Production at Scale

Best For: Mid-market and enterprise brands that need GEO-informed content at scale, without sacrificing brand voice.

Brafton has been doing content marketing since 2008, so they’ve seen every major search shift unfold in real time and adapted to it. Their take on GEO follows the same pattern: they treat it as an evolution of content marketing rather than a technical overhaul, and that philosophy shows in their execution.

Where some GEO agencies lead with schema markup and entity engineering, Brafton leads with content strategy and brand storytelling. Their GEO-informed work focuses on producing conversational, AI-friendly content that aligns with how users phrase questions in AI tools, built on strong sourcing, editorial consistency, and schema support at library scale. Their in-house team covers writing, design, video, and SEO.

Their GEO approach is better suited for brands competing on brand awareness and content volume in AI summaries than brands trying to win technically complex citation battles. Brafton clients tend to see gains in traffic and marketing-qualified leads backed by solid reporting on content performance, not necessarily granular AI citation tracking, which is where more specialized GEO agencies have an edge.

If your GEO priority is producing consistent, well-sourced content at scale that AI platforms are more likely to summarize, and you want that embedded in a broader content marketing program, Brafton delivers. If you need detailed share-of-voice tracking across AI platforms or aggressive technical GEO mechanics, you’ll want to supplement or look elsewhere.

Founded: 2008

Headquarters: Boston, MA

Team Size: 201-500 employees

Additional Services: SEO, PPC, Social Media Marketing, Video Production, Web Design & Development, Email Marketing, Content Strategy

Industries Served: Fintech, Manufacturing, Education, Health, Pharma, HR, B2B, and B2C 

Case Studies: TruGreen, EOS GmbH, and others.

Coalition Technologies: Full-Service Exclusivity Needs

Best For: Mid-market to enterprise brands wanting GEO integrated into a full-service digital marketing program.

Coalition Technologies is one of the larger agencies on this list, with 250+ team members across Los Angeles, Seattle, India, the Philippines, and Europe. Founded in 2009 by Joel Gross, they’re a top-ranked SEO and web design firm, and their GEO offering, branded as “Rank in AI,” extends that foundation.

Their approach to GEO is technical at its core: schema markup, structured content, voice assistant optimization, AI-tailored content formatting, and digital PR to build the third-party signals that LLMs weigh when deciding what to cite. They’re one of the few full-service agencies that demonstrate real GEO results on their own behalf, appearing in AI-recommended lists for searches around SEO agencies, which is a reasonable proxy for execution quality.

A notable case study: Coalition helped Pier 39 become a top AI-recommended local destination, showing that their GEO work extends beyond pure B2B into brand discovery for consumer-facing businesses as well. Their client roster is broad, including Sony, Harvard University, and thousands of retailers, reflecting their range across industries and business types.

The honest tradeoff here is scope. Coalition is a full-service agency first, and GEO is one capability within a much larger offering. For brands that want an all-in-one partner for SEO, PPC, web development, and GEO, that’s a feature. For brands that want deep GEO specialization and proprietary AI citation tracking, another agency may be a better fit.

Founded: 2009

Headquarters: Los Angeles, CA

Team Size: 201-500 employees

Additional Services: SEO, PPC, Paid Social, Web Design & Development, eCommerce Development, Email Marketing, Social Media

Industries Served: eCommerce, Retail, B2B, Healthcare, Finance, Consumer Brands 

Case Studies: Asphalt Kingdom, Food Fire Knives, and more.

How to Choose the Right GEO Agency for Your Brand

The right GEO agency isn’t necessarily the most well-known one, or the one that ranks highest for “best GEO agency.” It’s the one that’s actually built to solve your specific visibility problem. Here’s how to think through the decision.

Know What You’re Actually Buying

GEO isn’t one thing. Depending on the agency, you might be buying content production, technical optimization, digital PR, AI citation tracking, or some combination of all four. Before you talk to anyone, get clear on where your biggest gap is:

• Are you invisible in AI answers entirely, or just underrepresented?
• Is the problem your content, your authority signals, or your technical setup?
• Do you need someone to build the strategy, execute it, or both?

Your diagnosis should drive your shortlist. A brand that needs high-volume AI-optimized content at scale has different needs than one that needs to engineer citations in a competitive, technical category.

Ask for GEO-Specific Evidence

This is the fastest filter. Most agencies can show you SEO results. Fewer can show you documented improvements in AI citation rates, share of voice across ChatGPT or Perplexity, or prompt-level visibility data. Ask specifically:

• Can you show me a client whose brand mentions in AI answers increased as a result of your work?
• How do you measure AI visibility? What tools or platforms do you use?
• What does success look like at 90 days versus six months?

Vague answers here are a red flag. The agencies doing this well can be specific.

Match the Agency Model to Your Business

A boutique content agency that specializes in B2B SaaS thought leadership is not the right partner for an eCommerce brand that needs GEO at scale across hundreds of product categories, and vice versa. Consider:

• Industry Fit: Does the agency have experience in your vertical? GEO strategies that work in healthcare look different from those that work in fintech or consumer tech.
• Business Stage: Early-stage brands building authority from scratch need a different approach than established brands trying to defend category presence in AI answers.
• Service Model: Do you need a full-service partner that handles SEO, content, and GEO together? Or a specialized GEO shop to complement an existing in-house team?

Don’t Skip the Measurement Conversation

GEO without measurement is just content marketing with better branding. Before signing anything, confirm that the agency can tell you:

• Which AI platforms they track and how often
• How they define and report on share of voice across models
• Whether they can attribute changes in AI visibility to specific content or optimization moves

If you want to monitor AI visibility independently (or pressure-test what your agency is reporting) tools like Goodie let you track brand mentions and citation patterns across ChatGPT, Perplexity, Gemini, and other AI platforms in real time. It’s useful both for evaluating agency performance and for understanding the broader AI search landscape your brand is competing in.

Finding the Right GEO Agency for Your Brand 

If there’s one thing this list makes clear, it’s that “we do GEO” means something different depending on who’s saying it. For some agencies, it’s a content play. For others, it’s technical infrastructure. For others still, it’s PR and earned authority. The best programs combine all three, and the best agencies know which lever matters most for your specific business.

The good news: GEO compounds. Brands that invest early in AI visibility tend to build citation presence that’s hard for competitors to displace, especially as the platforms get better at recognizing and rewarding genuine authority.

The question isn’t whether GEO matters. At this point, that’s settled. The question is whether you’re building AI visibility intentionally or leaving it to chance.
