Finding the best GEO agency is key if you want your brand to show up in AI-powered search. With ChatGPT now reaching 900 million weekly active users, Google’s AI Overviews serving 2.5 billion people monthly, the brands that succeed are those showing up in AI search.
This guide walks you through what separates a genuinely capable GEO agency from one that simply slapped “AI optimisation” onto an existing SEO page. You’ll learn which criteria actually matter, what questions to ask, and how to avoid the most common mistakes when selecting a partner.
Whether you’re a B2B brand losing pipeline to competitors who show up in ChatGPT or an e-commerce business watching AI Overviews eat away at your organic traffic, you’ll leave with a clear framework for choosing the best GEO agency.
Common Mistakes When Choosing a GEO Agency
Even experienced marketers fall into these traps. Knowing what to avoid is just as important as knowing what to look for.
- Assuming any SEO agency can do GEO: a lot of SEO agencies have begun adding a “/geo” page to their website. That doesn’t mean they have the methodology, tools, or experience to deliver results.
- Optimising for ChatGPT alone: A credible GEO agency optimises across multiple AI platforms. Not every user is using ChatGPT, and with AI models routinely changing their trust signals, it’s worth distributing your presence across AI systems.
- Ignoring measurement from the start: GEO measurement is relatively new, but if an agency can’t explain exactly how it tracks success, that’s a red flag.
- Treating GEO as separate from SEO: the best results come from integrating GEO into your broader search strategy, rather than treating it as an isolated area of focus.
- Falling for vanity mentions: “Your brand appeared in a ChatGPT answer” sounds impressive, but without tracking citation accuracy, referral traffic, and conversion impact, it’s meaningless.
What Should I Look for in a GEO Agency?
Finding the best GEO agency requires a combination of clear evaluation criteria, honest conversations, and a willingness to look beyond agencies that simply repackaged their SEO offering. The eight criteria below will help you separate genuine specialists from generalists wearing a GEO hat.
- Multi-platform AI searchexpertise
The best GEO agency doesn’t just optimise for one AI system. It understands the nuances of ChatGPT, Google AI Overviews, Google AI Mode, Perplexity, Gemini, Claude, and Copilot. Each platform retrieves, processes, and cites content differently. An agency that treats all AI platforms the same way is missing some critical distinctions between models.
- Proventrack recordwith measurable outcomes
Ask for concrete results: increases in AI citation rates, growth in AI referral traffic, improvements in brand mention accuracy, and importantly, downstream business impact like leads, pipeline, or revenue.
Strong GEO agencies can point to specific outcomes, such as measurable increases in booked meetings or demonstrable improvements in AI visibility scores across multiple platforms. Pay attention to whether their experience aligns with your industry, business model, and market.
- Content strategy built for AI readability
In 2026, content structure is the single biggest lever in GEO performance. AI systems parse and cite content that’s clearly structured, factually explicit, and easy to extract. An agency that still writes fluffy marketing prose and hopes AI will pick it up is behind.
The best GEO agency will understand concepts like structured language – writing content with repeatable templates, labelled facts and controlled terminology that LLMs can interpret reliably. They know how to create content that works for both human readers and AI systems simultaneously.
- Robust monitoring and tracking capabilities
A credible GEO agency uses dedicated AI visibility monitoring tools – such as Otterly.AI, SISTRIX’s AI visibility features, Profound, Peec AI, or similar platforms – to track:
- Brand mentions across AI platforms
- Citation accuracy (is the AI saying the right things about you?)
- Competitor visibility in AI answers
- AI referral traffic in GA4
- Citation drift over time
If an agency can only show you traditional SEO dashboards, it’s not equipped for GEO.
- Entity and digital authorityexpertise
LLMs form their opinion about your brand by crawling your website and synthesising information from across the entire web. Your brand’s entity signals (such as authoritative third-party mentions) heavily influence whether AI systems recognise, trust, and recommend you.
The best GEO agencies understand digital authority management: building and strengthening these signals through earned media, digital PR, expert citations, and consistent brand information across trusted sources. Earned media is one of the most powerful GEO levers. Agencies with a PR heritage often understand this better than pure SEO agencies.
- Technical AI crawleroptimisation
Beyond content and authority, there’s a technical layer to GEO. The best geo agency knows how to:
- Implement and manage llms.txt files to guide AI crawlers
- Ensure proper schema markup and structured data
- Manage AI crawler access and crawl budgets
- Set up GA4 tracking for LLM referral traffic
- Optimise site architecture for AI content extraction
This technical foundation ensures that even the best content actually reaches AI systems in a format they can use.
- Flexible contracts and transparent pricing
GEO is still an emerging discipline, and the market is evolving rapidly. Avoid agencies that lock you into long-term contracts before proving their value. The best partners offer flexible arrangements with monthly retainers, short initial commitment periods, or phased engagements that scale as results materialise.
Whichever model you choose, ensure the agency’s incentives align with your goals.
Common pricing models include:
- Flat monthly retainer – predictable costs; typical for ongoing GEO monitoring and optimisation
- Project-based engagements – ideal for initial audits, strategy development, or content overhauls
- Hybrid model – base retainer plus performance components tied to agreed KPIs like citation rates or AI referral traffic
- Integration with broader digital strategy
While GEO specialisation matters, the best GEO agency will understand how AI visibility fits into the broader marketing mix. They should be able to articulate how GEO complements SEO, PPC, Digital PR and content marketing.
This cross-channel perspective is especially important because AI systems draw on signals from across the web. A brand with strong organic visibility, authoritative backlinks, consistent entity information, and positive third-party coverage will naturally perform better in AI answers than one optimising for AI in isolation.

What’s the difference between GEO and SEO?
SEO targets rankings, keywords, and clicks in conventional search engines. GEO takes things further: it’s about structuring content so that AI systems, such as ChatGPT and Google AI Overviews can accurately understand, categorise, and cite it as a source. The best results come from integrating both approaches rather than treating them as separate disciplines.
What’s the difference between GEO, LLMO, and AEO?
All three terms describe strategies for improving brand visibility in AI-generated answers, but with slightly different emphases. GEO (Generative Engine Optimisation) is the broadest and most commonly used term in 2026, covering visibility across all AI search platforms. LLMO (Large Language Model Optimisation) focuses specifically on large language models like ChatGPT and Claude. AEO (Answer Engine Optimisation) covers the broader category of answer engines, including featured snippets and AI Overviews.
Which types of businesses benefit most from working with a GEO agency?
GEO is especially valuable for information-rich and product-driven industries where AI-generated answers frequently appear. Businesses in these sectors can use GEO to recover lost clicks and protect their brand presence. Knowledge-based and consulting services also see strong returns, as their topics are often searched in question-and-answer formats, precisely the kind AI systems surface.
Are businesses already seeing actual results from GEO agencies?
Yes, many businesses report noticeably higher visibility in AI-generated results and more stable rankings, even amid fluctuating search engine updates. Bounce rates tend to drop when content is clearly optimised for AI readability, and conversion rates improve as users encounter the brand earlier in their research journey. The key is working with an agency that can track and prove these outcomes with dedicated AI visibility tools, such as Peak Ace.
What should businesses look for when choosing the best GEO agency?
Businesses should prioritise agencies with verifiable references and measurable results from successful projects. Depending on whether the focus is local or international, relevant market knowledge is essential. The ideal partner combines classic SEO expertise with genuine GEO capabilities, offers transparent strategies and clear reporting, and demonstrates a deep understanding of the client’s industry. Peak Ace, for example, brings together dedicated LLM Consulting, award-winning cross-channel capabilities, and a technology-driven approach built for the future of AI search.
