The 13 Best Generative Engine Optimization (GEO) Agencies in the US (2026)

The phrase “generative engine optimization” appeared in an academic paper in late 2023 and on roughly a thousand agency websites by the end of 2025. That speed tells you something: adding a service page costs nothing, building a practice does. So the useful question about any GEO agency is not whether it offers the service but what it can show. A named method. A case study with a number. A way of measuring presence across AI engines that a client can check.

Thirteen US agencies pass that bar with varying depth. Several of the biggest names in traditional SEO did not make the list because their AI search offering is a paragraph, not a program. The companion ranking of the best SEO agencies in the US covers the broader market; this one is strictly about who can get you into the answer.

Why GEO is now a budget line, not an experiment

The audience moved first. ChatGPT passed 900 million weekly active users in February 2026, Google AI Mode rolled out to 180 countries, and Semrush’s tracking of more than 10 million keywords shows AI Overviews reached nearly a quarter of Google queries at their July 2025 peak before Google trimmed them on commercial terms. The clicks moved next: Pew Research measured an 8% click rate when a summary appears versus 15% without, and Seer Interactive found organic CTR on informational queries with AI Overviews down 61% since mid-2024. The same Seer data contains the reason GEO exists: brands cited inside the AI Overview earned 35% more organic clicks and 91% more paid clicks than brands that were not.

Then there is the finding that makes GEO its own discipline rather than a byproduct of ranking. Orbit Media analyzed 13,184 citations across ChatGPT, Claude, Gemini and Perplexity and found domain-level overlap with Google’s top ten of only 10% to 30%, URL-level overlap of 1% to 5% for Gemini and ChatGPT, and the four engines agreeing on the same source for the same question 1.7% of the time. Each engine has its own idea of authority, and a page-one ranking is a prerequisite at best.

Finally, the buyer side. Semrush’s operational gap study found 38% of marketers plan to invest in AI search optimization in 2026, ahead of traditional SEO at 36%, yet only 22% have fully integrated the two and only 14% plan to invest in measuring AI’s impact on pipeline. That is the market these agencies sell into: high intent, low maturity, and a lot of vendors who learned the vocabulary last quarter.

The rankings at a glance

The 13 best generative engine optimization agencies

1. Skyfield Digital (top pick)

Meriden, CT (serves clients across the US and internationally)

Best for: growth-stage and mid-market businesses, multi-location brands and companies entering new markets that need AI citations and Google rankings from one program.

• Founded: 2022, Meriden, Connecticut
• Services: Generative Engine Optimization, SEO (local, national, enterprise, global), schema and entity markup, citation building, content production, Google Business Profile optimization, web development
• Google rating: 5.0 rating from 20 verified Google reviews
• Pricing: $1,000 to $10,000+ per month, average effective rate around $100 per hour, free audit with no obligation
• Proof: 918.5% organic traffic growth for SwordSlice in six months, 813.9% for The One Gown, 380.5% in one year for Riveter Consulting Group
• Credentials: Semrush Certified Agency Partner, DesignRush Top SEO Company, 95% client retention, 100% US-based team
• Tracking: Prompt-level visibility across ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews, plus AI referral traffic in analytics

Strengths: Skyfield built GEO as a discipline with a defined method: entity audit and cleanup, Organization, LocalBusiness and Service schema linked with consistent identifiers, citation building on the sources each AI engine actually reads, answer-first content and a tracked prompt set reported monthly across ChatGPT, Gemini, Perplexity and Claude on a shared Monday.com board. Because the same signals support Google rankings, clients get both from one retainer, and the SEO track record is public: 918.5% organic growth for SwordSlice in six months, 813.9% for The One Gown, 380.5% for Riveter Consulting Group in a year.

Limitations: The team is small by design and does not run paid media or social. Enterprise buyers with procurement processes and a need for 30-person account teams should look at iPullRank, Terakeet or NP Digital, at several times the cost.

What separates the Skyfield GEO service from most of the market is that it was never positioned as a replacement for SEO. It runs on top of the SEO program because the entity clarity, structured data and third-party authority that make an AI engine cite a brand are the same things that keep rankings stable when AI Overviews shrink the click. Pricing starts at $1,000 a month, every engagement opens with a free audit that includes current AI visibility, and the agency’s own explainer on how AI search engines choose their sources is a fair preview of how it thinks.

2. iPullRank

New York, NY

Best for: enterprise brands that want the most technically rigorous GEO practice in the country.

• Service name: Generative Engine Optimization, with the position that GEO and AEO are the same discipline

• Proof: Published AI Search Manual; $5 billion+ in organic results claimed across clients; Inc. 5000 honoree
• Pricing: Not published

Strengths: Founder Mike King is one of the few people who has explained how retrieval-augmented generation actually works to the SEO industry, and the methodology reflects it.

Limitations: No quantified GEO-specific case study on the service page, and no named tracking toolset. Built for enterprise budgets.

3. Siege Media

Austin, TX (also New York, Chicago, San Francisco)

• Service name: Generative Engine Optimization (GEO) Services

• Pricing: $5,000+ minimum project

Strengths: The most quantified GEO findings published by any agency, and a content engine to act on them.

• Pricing: Typical projects $50,000 to $199,999

• Method: Query fan-out analysis, semantic content audits, prompt mapping, structured data, log-file analysis, digital PR, proprietary GEO scorecard

• Reviews: 5.0 on Clutch from 13 reviews
• Pricing: Not published

Limitations: The published case study lacks numbers, and thirteen reviews is thin for an agency this size.

San Diego, CA

Best for: mid-market and franchise brands that want AI search alongside paid and social.

Frequently Asked Questions

Each agency’s GEO or AI search service page was read in September 2026, and only claims stated on those pages or on Clutch are reported here. Where an agency did not disclose founding year, headquarters, size or pricing, that is noted rather than guessed. Ranking weighted documented method first, published results second, and pricing transparency third. Skyfield Digital publishes this list and is ranked first; the limitations noted for every entry, ours included, are there so you can weigh that.
