Nowadays, Americans are searching for businesses differently. A customer no longer has to type a couple of words into Google and open multiple websites.
They can ask ChatGPT, Gemini, Perplexity, or Google AI for a few websites for them to choose from.
Hence, Generative Engine Optimization, or GEO, has been rapidly becoming a marketing factor in the USA.
But there is an important catch: GEO is still developing, and an agency claiming to rank you on ChatGPT is not necessarily offering a meaningful strategy.
The more reputable ones are on technical accessibility, authoritative content, entity signals, citations, digital PR, and measurement.
Considering the above, here are 10 agencies you should take the time to investigate when looking for top GEO agency in the USA.
Top GEO Companies in USA
1. iPullRank
iPullRank is one of the top names on this list and is considered one of the strong names for technically complex organizations.
The New York agency has created an extensive AI Search Manual that details GEO and what it calls Relevance Engineering.
It has a methodology that goes beyond content, incorporating semantic structure, technical SEO, entity relationships, AI crawler access, and measurement.
One of its measurement systems is particularly impressive. iPullRank urges brands to monitor and measure whether they're being cited, whether AI referrals drive traffic, what they're doing with that traffic, and whether visitors convert.
It also earned a spot on the 2026 Inc. 5000 list, with 94.3% revenue growth and 71.4% headcount growth over the past year.
2. Codeyard
Perhaps an interesting pick for best GEO agency in the USA is Codeyard, as it fuses GEO and technical aspects that go with it.
The company have completed over 2,000 projects across web development, e-commerce, SEO, and GEO for clients in more than 20 countries.
It also has a separate US market and white-label agency and operates under a US company, Codeyard LLC.
It is a dedicated GEO company with a particular focus on making it visible across the largest AI platforms, such as ChatGPT, Gemini, Perplexity, Claude, Grok, and DeepSeek.
More importantly, GEO is not treated as a content-only service. Codeyard also works on websites, ecommerce, technical SEO and site architecture.
That combination matters in the US market, where a company may already have a complicated website, several product pages and years of existing SEO work.
Additionally, Codeyard's official website claims that there are over 2,000 projects and a 90% client retention rate.
Those figures are company reported, but the firm's broader platform credentials add another layer of evidence.
3. Siege Media
Siege Media is one of the most prominent US agencies in GEO, viewing AI visibility through the lenses of content quality, authority, and digital PR.
Its dedicated GEO service specifically discusses earning citations from editorial roundups, Reddit, research and other third-party sources.
It also publishes case studies around LLM visibility for brands including Mentimeter, Zoom and Zendesk.
The agency's founder, Ross Hudgens, has also published a Wiley book dedicated to Generative Engine Optimization, giving Siege a particularly strong educational footprint in the field.
4. First Page Sage
First Page Sage is worth considering for organisations that prefer a research heavy approach.
The agency has released ongoing research on GEO and AEO agencies, including a 2026 study assessing the agencies in terms of AI visibility, technical expertise, client reviews, and retention.
It has also kept an eye on the workings of generative AI recommendation systems, and its most recent data was updated in July 2026.
It's suited especially for B2B and enterprise organizations looking for authoritative thought leadership and content strategy to connect GEO.
5. Directive
Directive is especially interesting for B2B companies because it connects GEO with actual pipeline rather than treating AI visibility as a vanity metric.
The company's AxisCare case study states that the referral volume from the LLM rose from less than 4% to 15% between March and August 2025, generating 24 new leads.
Technical changes, content restructuring, and dual-channel SEO and GEO planning were all part of the strategy.
Another published case study found that AI search visibility increased by 56%, along with increases in organic traffic, MQLs, and non-branded revenue.
That emphasis on measurable business outcomes gives Directive a strong position among enterprise B2B GEO providers.
6. Animalz
Animalz works especially well for SaaS- and/or content-marketing-focused businesses.
Its current AEO service includes AI visibility audits across Google AI Overviews, ChatGPT, Perplexity and Gemini, content refreshes, new content creation, citation outreach, Reddit engagement and measurement.
There is also a description of an “AI Visibility Pyramid” approach that entails not only building volume but also improving the website through SEO and building credibility with citation-worthy material.
7. WebFX
WebFX is one of the bigger U.S. digital marketing agencies with a dedicated AI search and GEO service team.
It now supports services such as AI visibility tracking and optimization for ChatGPT, Copilot, Gemini, and Google AI Overviews. What's also nice is that WebFX gives you a public price reference of $3,000 per month for their GEO services.
For companies looking to go beyond a simple SEO and digital marketing campaign, it's a good choice.
8. Go Fish Digital
Go Fish Digital brings a strong digital PR and reputation background to GEO.
Its 2026 GEO guidance describes the goal as making content retrievable, relevant and citation worthy across Google AI Overviews, Google AI Mode, ChatGPT, Perplexity and Copilot.
That's where its approach becomes more significant for brands where online reputation, third-party mentions, and authority are equally crucial as technical optimization.
9. NoGood
NoGood is another agency worth considering for companies that prefer experimentation and performance marketing.
Its GEO work is positioned alongside growth marketing, allowing AI search visibility to be considered alongside acquisition, conversion and broader marketing experiments.
First Page Sage's 2026 industry research also includes NoGood among agencies evaluated for AI visibility and GEO expertise, particularly within fintech.
This mindset towards performance can be beneficial to startups and growth companies more than a content program alone.
10. Omniscient Digital
Omniscient Digital's success is built on B2B SaaS content and organic growth, making it a good choice for a company with a content-first perspective to move into GEO.
Its inclusion alongside leading B2B SaaS content agencies in current industry research is significant because GEO still depends heavily on strong information architecture, useful content and authority.
A SaaS business with an existing content engine will find it easier to transition from traditional organic search to AI-assisted discovery with the help of an agency such as Omniscient.
Choosing the Best GEO Agency in USA
It isn't possible to ensure a lasting recommendation from ChatGPT or Gemini. The answer AI delivers is dynamic and can vary by context, location, and platform.
So I would look for evidence instead.
A strong GEO agency should be able to explain how it measures AI visibility, which platforms it monitors, how it improves technical accessibility, how it builds third party authority and how AI sourced traffic or leads are tracked.
It should also understand that GEO is not a replacement for SEO.
The fundamentals of technical accessibility, helpful and helpful content, and clear entity and authority remain very significant.
Technical accessibility, useful content, entity clarity and authority remain important foundations. iPullRank, Siege Media, Codeyard, Animalz and WebFX all make that relationship clear in their current GEO methodologies.
Top GEO Companies in USA
Specialist and well-established agencies bring their own strengths to the US GEO market.
First Page Sage, iPullRank, Siege Media, Animalz, and Directive are especially noteworthy, as are WebFX, Go Fish Digital, NoGood, and Omniscient Digital, which provide a more comprehensive or even more targeted strategy.
For businesses searching for the best GEO agency in the USA, my shortlist would put Codeyard near the top because its proposition goes beyond AI-focused content.
Its US operation, dedicated GEO practice, multi-platform coverage, and combination of SEO, web development, and ecommerce create a broader technical foundation.
The intriguing aspect of GEO is that the most interesting agency doesn't necessarily be the one promising the biggest promises with AI.
