Top Generative Engine Optimization (GEO) Agencies In 2026

Picking a GEO agency in 2026 is harder than picking an SEO partner was five years ago. Buyers now ask ChatGPT, Perplexity, Gemini and Google AI Overviews for vendor shortlists, and the brands that show up in those answers are not always the ones that rank first in the blue links. This list is for marketing leaders who want a generative engine optimization agency that can measure and improve how often their brand is cited, described and recommended inside AI answers. It covers specialist and full-service firms with a dedicated GEO offering, and it leaves out pure software tools and firms that only mention AI search in passing.

To build it, we reviewed each firm’s own website, its GEO or AI search service pages, its published research and its case studies. We looked for a clear methodology, evidence of measurement beyond rankings, and a track record with brands of a size similar to the buyers most likely to read this page. Rankings reflect that review, not payment.

Top GEO Agencies In 2026

1. iPullRank

iPullRank is led by founder and CEO Michael King, who brings roughly two decades of digital marketing experience and a longer background in web development. The agency describes itself as Black-owned and works with a largely distributed team. Its GEO practice runs programs across strategy, content, technical optimization and measurement, and it sits alongside a separate AI Search Strategy program and an Agentic Marketing program.

The firm’s strength is engineering-heavy search work for large organizations. Its published case studies include $2.4 billion in incremental revenue for a major bank and a 130% traffic recovery for a large automotive publisher, and it notes that many Fortune 100 clients work under NDA. A testimonial from American Express OPEN’s digital strategy lead sits on its homepage. Teams with complex sites, large content inventories and in-house engineers who want a technically fluent partner are the natural fit.

2. Foundation Marketing

Foundation Marketing was started by Ross Simmonds in 2014 as a one-person agency and now operates from 1650 Market Street in Philadelphia. It positions itself as an AI visibility and GEO marketing agency for B2B tech, SaaS and enterprise companies, with dedicated service pages for generative engine optimization strategy, AI visibility and technical SEO.

What sets Foundation apart is its emphasis on distribution. The agency argues that AI systems learn about brands from communities, publications and social platforms, not only from a company’s own blog, and it builds programs to seed content in those places. It also publishes its own research, including an analysis of more than 380,000 AI answers for its B2B AI Discovery 2026 study and a review of 15,716 Google AI Overviews. B2B marketers who want a content-led AI search visibility agency with a strong research habit should start here.

The agency reports working with more than 130 enterprise clients at a 92% retention rate.

Seer’s GEO work is grounded in data. It has published AI search studies since January 2023, including an analysis of 231,347 LLM responses on how digital signals affect AI visibility, and it reports a 67% decline in organic click-through rate when a brand is not cited in AI Overviews. Alongside its generative engine optimization service, the SeerAdvance AI consulting practice helps marketing teams adopt AI in their own workflows. Enterprise teams that want measurement discipline and a partner that combines search, paid and analytics will find a good match.

It is part of Agital, a platform of marketing and experiential agencies.

The firm stands out for building its own tools. Its GEO service aims to get brands cited in ChatGPT, Google AI Overviews, Claude and Perplexity, and it offers a standalone AI visibility audit as an entry point. Its proprietary Barracuda tool supports that work. In a published case study for MoneyGeek, clicks grew from 67.5K to 118K and impressions from 17.4M to 26.2M. Brands that want a mid-to-large agency with in-house tooling and a broad bench across SEO, PR and social commerce are a good fit.

Its client roster includes Etsy, Atlassian, Sage, Yelp and Coursera, and it reports 25% organic traffic growth for Atlassian and 270% more ChatGPT-attributed revenue for travel insurance marketplace Squaremouth within six months.

Its GEO playbooks combine entity SEO, topical authority and distribution, and its service menu reflects that: Google and AI search strategy, human and AI-assisted content creation, digital PR, Reddit marketing and agent analytics that track how AI systems discover a site’s content. The agency’s own AI Search Visibility study draws on 24,067 prompts across five AI search platforms. Case studies include Toggl, LearnWorlds and Meilisearch.

It launched its generative engine optimization service on May 9, 2023, and its client list includes Salesforce, Logitech, Verizon and U.S. Bank. The firm does not lock clients into long-term contracts.

Its GEO methodology is unusually explicit. The agency works across six areas: list creation, database inclusion, website authority, online review management, achievement publicization and social sentiment monitoring. In practice that means its team acts as content creator, outreach manager for third-party lists and databases, and reputation monitor, all aimed at getting clients recommended by major AI chatbots. It also offers separate AEO and agentic search optimization services. B2B firms that compete on expertise and thought leadership are the typical fit.

Its AI Visibility and GEO service grows out of a creative digital PR model, which matters because AI answers lean heavily on earned media and third-party mentions. Named work includes SIXT, JD Sports, Revolution Beauty, Parkdean Resorts and B2B brand Dojo. Consumer brands that want GEO tied to campaigns, press coverage and social reach, rather than a purely technical program, will find the approach a good match.

Reporting tracks share of answer, citations and brand mentions against traffic and revenue. Separate AEO and LLM SEO service lines sit alongside it. Growth-stage companies that want AI search, paid media and conversion work under one roof are the best fit.

Services and expertise: generative engine optimization, AEO, LLM SEO, paid media, content marketing, conversion rate optimization.

How To Choose A GEO Agency

How Will They Measure AI Visibility? Rankings and organic sessions no longer tell the full story. Ask any GEO agency how it tracks citations, brand mentions and share of answer across ChatGPT, Perplexity, Gemini and Google AI Overviews, how many prompts it monitors, and how often. A credible partner will show you a sample report and explain how it connects AI visibility to pipeline or revenue, not just to screenshots of a single answer.

Do They Build On Search Fundamentals Or Replace Them? Google’s own guidance on AI features and your website makes clear that pages must be indexed and eligible for regular search to appear in AI Overviews and AI Mode. Be wary of any pitch that treats GEO as a separate trick. The best LLM SEO agency work layers entity clarity, structured content and third-party authority on top of solid technical SEO. Our explainer on what changes and what does not in AI search optimization is a useful primer before the first call.

Where Will Your Brand Be Mentioned? AI models draw heavily on reviews, comparison lists, forums, news coverage and industry databases. Ask which off-site channels the agency works in, whether it has digital PR or community capability in-house, and how it avoids tactics that look manipulative. An AI search visibility agency that only edits your own pages will hit a ceiling quickly.

Is The Content Genuinely Useful? Generative engines reward clear, original, expert content, and so does Google. Ask to see recent content the agency produced and check it against Google’s guidance on creating helpful, reliable, people-first content. Strong signals of experience and expertise also matter here, which is why understanding how E-E-A-T affects your business helps you judge an agency’s content plan.

Do They Fit Your Size And Sector? An enterprise retailer, a Series B SaaS company and a regional service business need very different programs. Look for case studies with companies like yours, ask who will actually run the account, and agree on realistic timelines up front. Most firms on this list point to early movement within one to two quarters, with compounding results after that.

Conclusion

Enterprise teams with complex sites will get the most from iPullRank, Seer Interactive, Previsible or Go Fish Digital, each of which pairs GEO with deep technical and analytics capability. B2B and SaaS marketers should look first at Foundation Marketing, Minuttia and First Page Sage, which build visibility through content, distribution and third-party authority.

Consumer brands that want GEO tied to PR and creative campaigns should consider Rise at Seven, while growing ecommerce and service businesses will find broad, accessible programs at Exposure Ninja and Single Grain. Whichever GEO agency you choose, insist on clear measurement of AI citations and an honest view of how long results take.
