15 Best Generative Engine Optimization (GEO) Agencies in 2026

If you’re still measuring digital success purely by Google rankings, you’re already behind. Something fundamental shifted in how people find information, and it happened faster than most marketing teams expected.

Users are no longer just searching. They’re asking. And AI is answering.

When someone asks ChatGPT, “What’s the best accountant for a small business in Melbourne?” or asks Perplexity, “Which marketing agency should I hire for SEO?”, they don’t get ten blue links. They get a direct answer, with specific brand recommendations, backed by citations. If your business isn’t one of those recommendations, you don’t exist in that moment.

That’s the problem Generative Engine Optimization (GEO) solves. GEO is the practice of optimising your content, authority signals, and digital presence so that AI-powered platforms, including ChatGPT, Google AI Overviews, Perplexity, Gemini, and Microsoft Copilot, cite and recommend your brand when answering relevant queries.

The numbers make the urgency clear. According to eMarketer’s 2026 GEO report, fewer than 10% of sources cited in ChatGPT, Gemini, and Copilot rank in the top 10 Google organic search results for the same query. Traditional SEO alone will not get you into AI answers. You need a dedicated GEO strategy.

The challenge? GEO is still a new discipline. Most agencies are still catching up. Only a handful have built genuine, proven frameworks for getting brands cited consistently across AI platforms.

We’ve done the research to find them. Here’s our list of the 15 best GEO agencies in 2026, what each one does best, and how to choose the right fit for your business.

Key Takeaway: GEO and SEO are complementary, not competing. The brands winning in AI search are those that invest in both, not one or the other.

What Is Generative Engine Optimization (GEO)?

Generative Engine Optimization is the practice of structuring your content and digital presence so that AI-powered search platforms can retrieve, understand, and cite your brand when generating answers for users.

Traditional SEO asks: “Are we ranking on page one?” GEO asks: “Are we inside the answer?”

According to Search Engine Land’s 2026 GEO guide, when an AI engine names your brand in its response, it delivers an implicit endorsement that no organic listing ever could. AI platforms typically cite only two to seven domains per response, making the competition more selective than a Google SERP.

How GEO Differs from Traditional SEO

Aspect	Traditional SEO	Generative Engine Optimization
Output format	List of clickable links	Synthesised narrative response
User behaviour	User clicks through to find information	User gets the answer directly
Query length	Short keywords (avg. 4 words)	Conversational questions (avg. 23 words)
Success metrics	Rankings, CTR, organic traffic	Citations, brand mentions, share of voice
Optimisation focus	Keywords and backlinks	Content structure and authority signals
The key question	“Are we on page one?”	“Are we in the answer?”

What GEO Actually Involves

A proper GEO strategy covers four interconnected areas:

1. Content structure: Publishing information that AI systems can discover, extract, and reassemble into answers. Self-contained paragraphs, clear headings, and direct definitions are essential.

2. Entity authority: Establishing your brand as a recognised, trusted entity across platforms where AI tools pull information, including review sites, industry publications, and social platforms.

3. Technical foundations: Ensuring AI crawlers (GPTBot, ClaudeBot, PerplexityBot) can access and parse your content. Schema markup, clean site architecture, and an llms.txt file all play a role.

4. Reputation signals: Earning third-party mentions, citations, and reviews that signal credibility to AI systems. Princeton research confirms that AI engines strongly favour earned media over brand-owned content.

GEO isn’t a one-time project. It’s an ongoing discipline that demands the same rigour as traditional SEO.

How to Choose the Right GEO Agency for Your Business

Not every agency on this list is the right fit for every business. Here’s how to narrow it down based on your situation.

Match the Agency to Your Business Stage

Business Stage	What to Prioritise	Best-Fit Agencies
SME / Local business	Integrated GEO + SEO, local authority building	Global Genie Marketing
Growth-stage startup	GEO inside a full-funnel growth system	NoGood, Single Grain
B2B SaaS (early)	Prompt-level testing, AI citation gap analysis	Rock The Rankings, Minuttia
B2B SaaS (enterprise)	Entity authority, category ownership	Omniscient Digital, Minuttia
Enterprise / Large site	Technical GEO, governance, schema at scale	iPullRank, Victorious, WebFX
eCommerce	Content freshness, semantic structure	Siege Media, Go Fish Digital
High-volume content needs	Scalable GEO content production	Brafton, Foundation

Questions to Ask Any GEO Agency Before Signing

Before committing to an agency, ask these directly:

1. How do you measure GEO performance? Look for specific answers: citation frequency, share of voice in AI responses, AI referral traffic. Vague answers about “visibility” are a red flag.

2. Which AI platforms do you optimise for? A solid GEO programme covers ChatGPT, Perplexity, Google AI Overviews, Gemini, and Copilot, not just one.

3. Can you show examples of clients you’ve gotten cited in AI answers? Ask for specific prompts and screenshots. Real GEO work is demonstrable.

4. How do you handle technical AI crawlability? They should mention GPTBot, ClaudeBot, PerplexityBot, schema markup, and robots.txt review.

5. How does your GEO work integrate with existing SEO? GEO and SEO should reinforce each other. An agency that treats them as separate silos will create gaps.

Red Flags to Watch For

• Agencies that rebrand standard content marketing as “GEO” without any technical or entity work

• No mention of AI crawler accessibility or schema implementation

• No measurement framework beyond traditional SEO metrics

• Promises of immediate results (GEO, like SEO, is a compounding long-term investment)

The Metrics That Define GEO Success

One of the most common questions we hear from businesses exploring GEO is: “How do we know if it’s working?” The answer requires a different measurement framework than traditional SEO.

According to Search Engine Land’s GEO guide, the key metrics for GEO performance are:

• Share of voice: How frequently your brand appears in AI responses across a broad range of prompts in your category. This is the most important GEO metric.

• Citation frequency: How often specific pages on your site are being cited by AI engines when answering target queries.

• Competitive rank: Where you appear relative to competitors in AI-generated answers. First mention carries significantly more weight than fifth.

• Brand mention accuracy: Whether AI systems describe your brand correctly and favourably. Inaccurate AI descriptions are a real problem, and one that requires active management.

• AI referral traffic: Direct traffic from AI platforms, trackable via server logs (look for the “ChatGPT-User” user agent) or analytics platforms that now report AI referral sources.

The honest truth about GEO timelines: Most businesses start seeing measurable citation improvements within three to six months of a properly executed GEO programme. Meaningful share-of-voice gains in competitive categories typically take six to twelve months. Anyone promising faster results is overpromising.

Final Thoughts: GEO Is No Longer Optional

Gartner estimates that traditional search engine volume will decline by 25% as AI assistants become the default discovery interface. That’s not a prediction for five years from now. It’s already happening.

The businesses that invest in GEO today are building a compounding advantage. Every citation earned, every entity signal established, and every piece of AI-ready content published makes the next citation easier to win. The brands that wait are not standing still; they’re falling behind as their competitors accumulate AI visibility that becomes increasingly difficult to displace.

The agencies on this list represent the best of what the GEO space currently offers. Whether you need full-service GEO integrated with traditional SEO, specialist B2B SaaS AI visibility, or enterprise-scale technical optimisation, there’s a right fit on this list for your situation.
