What Does a GEO Agency Do?

Buyers increasingly ask an AI assistant to shortlist, compare or recommend a supplier before they ever open a search engine results page. A GEO agency exists to make sure your business is one of the answers those assistants give — named accurately, described fairly and backed by evidence the model can trust.

This guide breaks down exactly what a GEO agency does day to day: the platforms it works across, the services it delivers, how a GEO audit runs, how results are measured, and when it makes sense for a business to bring one in — the same remit behind our GEO agency services.

Key takeaways

A GEO agency optimises for citation and mention inside AI-generated answers, not for a ranking position on a results page.
Core services include visibility audits, prompt research, content planning, entity optimisation, digital PR and citation tracking.
GEO agencies work across ChatGPT, Google AI Mode, Gemini, Perplexity and Microsoft Copilot, since each retrieves and weighs sources differently.
GEO builds on solid SEO and technical foundations rather than replacing them.
No agency can guarantee a specific AI mention, but disciplined GEO work meaningfully improves the probability of being cited.

What is a GEO agency?

A GEO agency is a specialist marketing partner focused on generative engine optimisation: making a brand easy for AI systems to retrieve, understand and cite when they compose an answer. Rather than chasing traditional rankings, a GEO agency works to get a business named, described accurately and referenced as a trusted source inside a generated response — whether that is a product recommendation, a comparison, or a shortlist of local suppliers.

Which platforms does a GEO agency optimise for?

Each generative engine retrieves and weighs sources slightly differently, so a competent GEO agency tests and optimises across all the platforms your customers actually use.

ChatGPT — the most widely used consumer AI assistant, now a genuine research and shortlisting tool for buyers.
Google AI Mode — blends Google's index with generative summarisation and follow-up questions.
Google Gemini — Google's assistant, used for research, comparison and planning tasks.
Perplexity — an "answer engine" built around retrieval and visible citations.
Microsoft Copilot — integrated into Bing search and Microsoft's productivity suite.

What services does a GEO agency provide?

Visibility audits — testing how, and whether, your brand currently appears across major generative engines.
Prompt research — identifying the real questions and phrasing buyers use when researching your category.
Content planning — mapping topic clusters, comparisons and evidence-led content that fills visibility gaps.
Entity optimisation — making your name, offering, locations and credentials consistent and unambiguous everywhere.
Digital PR — earning third-party coverage and mentions that corroborate what your site says about you.
Technical SEO — ensuring AI crawlers such as GPTBot and PerplexityBot can access and read your site.
Citation tracking — ongoing monitoring of mentions, accuracy and sentiment across AI platforms.

How does a GEO audit work?

A GEO audit starts by running a consistent set of real customer prompts across ChatGPT, Gemini, Perplexity and Copilot to see whether your brand appears, how it is described, and which competitors are named instead. The agency then checks technical accessibility — whether AI crawlers can reach your site — reviews entity consistency across your website and external listings, and assesses whether your existing content contains clear, quotable claims and evidence. The output is a prioritised list of gaps: missing topics, inconsistent information, weak authority signals and technical blockers.

How does a GEO agency improve content?

A GEO agency rewrites and restructures content so a model can extract a clean, accurate fact rather than having to infer one. That means leading with a direct answer, using short declarative statements, backing claims with data and named credentials, and building genuine topical depth around a subject rather than one isolated page. Formats such as comparisons, definitions, original research and case studies tend to perform particularly well because they give a model something specific and quotable to cite.

Why brand authority matters

Generative engines weigh how consistently and credibly a brand is discussed across the web, not just what a brand says about itself. A business with genuine topical authority — demonstrated expertise, real evidence and a track record other sources corroborate — is far more likely to be retrieved, trusted and named than one relying on on-site marketing copy alone. Building this authority is usually the single biggest driver of durable GEO visibility.

How GEO agencies earn third-party signals

Because generative engines cross-check sources against each other, independent corroboration matters. A GEO agency typically runs a digital PR programme to secure expert commentary, press coverage and industry directory listings, encourages genuine reviews, and builds relationships that lead to natural mentions on sites you do not control. These third-party signals are often what tips a model from including a brand as "possible" to naming it directly in an answer.

GEO agency vs SEO agency

The two disciplines share technical foundations but differ in objective, method and measurement.

GEO agency compared with SEO agency
Factor	SEO agency	GEO agency
Primary objective	Rank position on a results page	Be named and cited within an AI-generated answer
Core deliverable	Optimised pages, backlinks	Entity clarity, citable content, third-party corroboration
Content focus	Keyword-relevant, comprehensive pages	Clear, original, quotable claims and evidence
Authority building	Backlinks, domain authority	Consistent entity data, digital PR, expert credentials
Measurement	Rankings, organic traffic, CTR	Citation frequency, brand mentions, AI referral traffic
Typical overlap	Technical health, crawlability, helpful content — shared by both

In practice, most businesses need both. As explored in why good GEO and AEO is just good SEO, a strong GEO agency builds on the same technical and content foundation as good SEO rather than working against it — an AEO agency narrows that further to individual answer-ready content.

How are GEO results measured?

Mentions — how often your brand is named across a fixed set of test prompts.
Citations — how frequently your pages are directly linked or referenced in generated answers.
Links — inbound links and third-party coverage that support wider authority.
Referral traffic — visits arriving from ChatGPT, Perplexity, Copilot and other AI platforms in analytics.
Assisted conversions — enquiries or sales where an AI platform played a role earlier in the journey.
Brand-search growth — a lagging indicator showing rising awareness driven by AI-influenced discovery.

What can a GEO agency realistically promise?

No reputable GEO agency can guarantee a specific mention inside an AI-generated answer, since none of the underlying models are controlled by publishers or agencies. What a credible agency can promise is a structured, evidence-based programme — technical fixes, entity consistency, genuine authority building and ongoing monitoring — that measurably improves the probability of being retrieved and cited, tracked transparently against a defined baseline.

When should a business consider hiring one?

It is worth engaging a GEO agency once you notice competitors being named in AI answers where you are absent, once a meaningful share of your buyers research using AI assistants before contacting you, or once your existing SEO is solid but you have no visibility into how AI platforms currently describe your brand. The earlier a business starts building topical authority and entity consistency, the stronger its position as AI-driven research continues to grow.

Frequently asked questions

How is a GEO agency different from an AEO agency?+

A GEO agency focuses on a brand's overall visibility and credibility across the whole generative AI ecosystem, while an AEO agency concentrates on structuring individual pieces of content so specific questions can be answered and extracted directly, such as featured snippets or AI Overviews.

Do I need a GEO agency if I already have an SEO agency?+

Many SEO agencies now offer GEO as an extension of their existing work, since the two disciplines share the same technical and content foundations. Whether you need a separate specialist depends on whether your current agency actively tests, tracks and optimises for AI platforms specifically.

How much does GEO agency work cost?+

Costs vary with the scope of the audit, content production and digital PR involved, but GEO work is typically priced similarly to established SEO or content marketing retainers, reflecting the ongoing research, writing and monitoring required.

How long before a GEO agency shows results?+

Some entity and technical fixes can improve citation accuracy within weeks, but building the sustained topical authority generative engines trust typically takes several months of consistent work, similar to organic SEO timelines.

Can a small business benefit from hiring a GEO agency?+

Yes. Generative engines reward clarity, consistency and genuine expertise over sheer size or budget, so a well-structured small business can be cited alongside or instead of much larger competitors.

What tools do GEO agencies use to track visibility?+

Most run a combination of manual and automated prompt testing across ChatGPT, Gemini, Perplexity and Copilot, alongside analytics segmentation for AI referral traffic and brand-search monitoring.

Will a GEO agency also improve my traditional SEO?+

Generally yes, because GEO work depends on the same crawlable, well-structured, authoritative content that traditional SEO requires, so improvements in one area typically support the other.

Conclusion

A GEO agency improves how clearly and credibly a brand appears across generative search platforms — auditing current visibility, strengthening entity and content clarity, earning genuine third-party corroboration, and tracking whether AI assistants actually name your business when it matters. It is a discipline built on solid SEO foundations, not a replacement for them.
