Top 10 Generative Engine Optimization Agencies (GEO) for 2026

Times are changing fast and now you are here trying to find an agency who can actually help you show up in generative engines.

It’s hard though because GEO is still new. And like we’ve seen with past trends, there are a lot of purported experts.

So here’s a list of companies we’ve put together to help you with your search.

How we evaluated the best GEO agencies

The difficulty with evaluating GEO agencies compounds the same issues we already have with evaluating SEO agencies.

SEO isn’t like hiring a branding agency where you can just look at a portfolio and judge the work. With SEO, you can't do a quick look at a site and say, "Great job!" 

This creates one dimension of difficulty.

But with GEO being so new, and with so much still unknown, the BS radar is even harder for the average marketer and brand to detect.

So the main method we used to evaluate an agency’s GEO capability centered around:

Thought leadership and expertise
Conference speaking, solid content, and how the SEO community responds to their work.

Relationships
Zupo is active in the search community, so we get an inside look at which agencies are actually doing meaningful work versus simply talking about it.

Body of work
The agency’s track record from SEO into GEO. We looked for proof they can execute, not just position.

Industry fit
Some agencies are better fits depending on your situation, like healthcare, tourism, multi-location, enterprise, or B2B.

Quick comparison

1. Zupo (Best overall for GEO that stays grounded in measurable outcomes)

Best for: B2B teams that want an ambitious GEO program tied to measurable improvements in AI visibility.

Let’s just come right out with it, we think we are the best.

Zupo takes GEO beyond general best practices and turns it into a focused strategy built around the prompts that actually matter for your business.

Our AI Visibility and GEO framework focuses on a complete top down approach, helping brands ensure:

Winning in GEO with Zupo is proactive. The goal is to make sure AI models understand your brand the way you intend to.

How to choose the right GEO partner

All of this is probably a bit overwhelming. Our list is probably not the only one you are looking at, so easily you can have 20 to 30+ brands that you are seeing.

At the end of the day, I have always run my marketing career with the idea that we need to give more businesses a great marketing experience. That doesn’t necessarily need to come from us.

Saying that, here are some questions that I’d recommend you ask agencies:

• How do you measure AI visibility today? (prompt testing, tracking mentions, tracking citations, competitive benchmarks)
• What methods do you use to improve AI visibility? Can you share a step by step example?
• How are you acquiring fan out queries?
• What is your approach to selecting prompts for tracking and optimization?

What GEO means

Generative Engine Optimization is ensuring that you (whether that's a brand, organization, a person) appears in AI answers. 

In practice, this usually includes:

• Content structure that generative engines can parse (clear headings, Q&A blocks, bullet lists, tables)
• Entity clarity and topical depth (so your brand becomes the best source for a topic, not just one page)
• Technical signals that reduce ambiguity (schema markup, clean indexing, page quality)
• Visibility measurement across AI surfaces through prompt testing, monitoring mentions, and tracking how your brand shows up in AI responses

Zupo’s GEO and AI Visibility content leans heavily on structured formats and schema as “translation layers” that help systems interpret your pages with higher confidence.

GEO’s relationship with SEO

The full brunt of Generative Engine Optimization, or what we at Zupo like to call AI Visibility, is here.

Whether or not you personally have adopted AI search, the influence of using AI for research and decision making is growing rapidly. Users are continually using AI to help understand options, compare vendors, and figure out what to do next.

And despite the initial reaction of “AI is going to kill SEO,” the truth is brands have more control than people think when it comes to showing up in AI responses.

Yes, that means you have a lot of control over your brand’s ability to show up in answers.

That shift is why new terms have shown up as SEO evolves. You’ll see a handful used interchangeably:

• Generative Engine Optimization (GEO)
• Answer Engine Optimization (AEO)
• LLM Optimization (LLMO)
• AI Visibility

Functionally, most people are describing the same thing. The main difference is the lens they use to talk about it.

For this post, we’re sticking with GEO.

Conclusion

GEO is not a single tactic. It’s a combination of technical clarity, structured content, topical authority, and credibility signals that help generative engines confidently cite your brand.

If you want a partner that treats GEO as a measurable program, not a buzzword, Zupo is the top pick on this list because of its explicit focus on AI Visibility audits, structured optimization, and practical measurement through prompt testing and AI visibility best practices.
