Search is no longer confined to a page of ten blue links. Generative engine optimization is becoming part of the search strategy as people increasingly use AI systems to research products, services, and companies, and more brands are hiring a GEO consultant to keep pace.

People ask ChatGPT for software recommendations, use Perplexity to research purchases, turn to Gemini for comparisons, and encounter Google AI Overviews before they reach traditional organic results. These experiences can synthesize information from multiple sources and produce an answer without requiring the user to visit every source used to create it.

That changes what companies should expect from SEO.

Ranking remains valuable, but businesses increasingly need to understand whether their brands appear in AI-generated answers, which sources influence those answers, and why competing companies may receive citations or recommendations when they do not.

A GEO agency helps companies address that problem.

GEO, or generative engine optimization, combines elements of SEO, content strategy, technical SEO, digital PR, entity optimization, and measurement to improve a brand’s visibility within generative and AI-powered search experiences.

The discipline is still developing. That makes choosing a GEO agency unusually difficult. Agencies use terms including GEO, AEO, LLMO, AI SEO, answer engine optimization, and relevance engineering to describe overlapping services.

The terminology matters less than the underlying work.

A capable GEO agency should be able to explain how it measures AI visibility, identifies gaps, improves the information available about your business, earns credible brand mentions, and connects those activities to measurable business outcomes.

What Is a GEO Agency?

A GEO agency is a marketing agency or consultancy focused on improving how brands, products, services, and subject-matter expertise appear across generative search engines and large language model interfaces.

Traditional SEO typically concentrates on improving visibility within search engine results. A GEO agency expands that scope to systems such as ChatGPT, Gemini, Perplexity, Claude, and Google AI Overviews.

This does not mean GEO replaces SEO. Google’s Danny Sullivan has similarly said that “good SEO is good GEO”, reinforcing the substantial overlap between established search optimization practices and optimization for AI search experiences.

AI systems still depend on accessible, relevant, authoritative information. Strong crawlability, useful pages, backlinks, structured data, topical authority, and brand authority remain important foundations.

The difference is the environment being optimized.

A traditional SEO question might be:

Does our page rank for the target keyword?

A GEO question might be:

When a buyer asks an AI system about this problem, which brands and sources are included in the answer, and why?

That distinction affects everything from research to reporting.

GEO vs. SEO vs. AEO

GEO, SEO, and AEO overlap considerably, but they are not necessarily interchangeable.

SEO focuses primarily on organic search visibility. The work can include keyword research, content production, technical SEO, link acquisition, internal linking, and improving site architecture.

AEO, or answer engine optimization, focuses on making information easier for search systems to interpret and present as direct answers. Clear content structure, schema, concise definitions, and question-and-answer formats can all support AEO.

Generative engine optimization focuses more specifically on visibility within AI-generated answers.

That can involve traditional SEO and AEO practices, but a GEO agency should also examine how AI systems interpret a brand across the broader web.

This is why a serious AI SEO strategy cannot simply consist of adding FAQs to existing pages or generating more content with AI.

The underlying question is broader: Does the available evidence give an AI system enough reason to understand, trust, cite, and potentially recommend this brand?

What Does a GEO Agency Actually Do?

There is no universal GEO service package yet. Different agencies approach the problem differently.

However, a comprehensive GEO agency engagement should generally address five areas.

1. Measure Current AI Visibility

Optimization should begin with measurement.

A GEO audit can establish how frequently a company appears for commercially relevant prompts across systems such as ChatGPT, Perplexity, Gemini, and other AI-driven search experiences.

That analysis may examine:

  • Brand inclusion in AI-generated answers
  • Competitor visibility
  • AI citations and cited domains
  • Brand mentions
  • Prompt categories
  • Topic coverage
  • Sentiment or positioning
  • Changes in AI search visibility over time

AI visibility tracking is more complicated than traditional rank tracking because generative systems can produce different answers for similar prompts.

A useful GEO agency should therefore avoid presenting AI visibility as a perfectly deterministic ranking system.

Instead, measurement should look for patterns across strategically selected prompts and repeated observations.

2. Build a Search and Prompt Strategy

Keyword research is still useful, but AI-powered search creates additional research requirements.

Users can have long, conversational interactions with an AI assistant rather than typing one keyword and choosing a result.

Generative systems may also decompose a question into related information needs. This behavior is commonly discussed in the context of query fan-out, particularly as search platforms expand complex questions into supporting searches or subtopics.

That means a GEO content strategy should consider the network of questions surrounding a topic.

For example, someone searching for a GEO agency might also investigate:

  • GEO vs. SEO
  • GEO agency pricing
  • AI SEO agency services
  • How ChatGPT chooses sources
  • How to appear in Perplexity
  • Google AI Overviews optimization
  • AI citation tracking
  • GEO reporting
  • GEO case studies

Understanding this query fan-out helps a company create useful coverage rather than treating every keyword as an isolated page.

3. Improve Content Quality and Structure

Good GEO does not mean stuffing AI-related terminology into a page.

Content quality still matters.

A GEO agency should evaluate whether important pages provide clear, useful, evidence-based information that both humans and machines can understand.

This can include improving:

  • Definitions
  • Headings
  • Entity relationships
  • Supporting evidence
  • Original research
  • Expert commentary
  • Comparison content
  • FAQs
  • Internal links
  • Content freshness

Content structure becomes especially important when pages attempt to answer complex questions.

Clear sections, direct answers, descriptive headings, and well-supported claims make information easier to retrieve and interpret. Structured data and appropriate schema can also help search engines understand page context.

Neither schema nor structured data should be sold as a magic GEO switch. They are components of a broader information architecture and technical foundation.

4. Strengthen Off-Site Brand Authority

Your website is not the only source an AI system can use to understand your company.

This is one of the most important distinctions between basic on-page optimization and a more mature GEO strategy.

A company’s reputation can be reflected across publications, industry sites, reviews, directories, communities, research, and other third-party sources.

This makes digital PR relevant to generative engine optimization.

Earning legitimate coverage and brand mentions can strengthen the body of information available about a business. High-quality backlinks can still support SEO while also increasing the discoverability of useful third-party references.

Some practitioners refer to intentionally improving the sources and passages likely to support generative answers as citation engineering.

The goal should not be manufacturing artificial AI citations.

The objective is to make authoritative, verifiable information about the brand available in places that people and search systems already trust.

5. Fix Technical Barriers

A GEO agency still needs technical competence.

If important information cannot be efficiently discovered, rendered, interpreted, or indexed, sophisticated AI visibility tactics are unlikely to compensate for the underlying problem.

A technical SEO audit can help identify issues involving:

  • Crawlability
  • Indexability
  • Canonicalization
  • Internal linking
  • JavaScript rendering
  • Structured data
  • Site architecture
  • Duplicate content
  • Page performance

You may also hear agencies discuss llms.txt.

The proposed llms.txt standard is intended to provide LLM-friendly information about a website. However, companies should be cautious about treating it as a proven ranking factor or universal requirement for AI visibility.

[Unverified] I cannot verify that implementing llms.txt directly improves rankings or citations across major generative search platforms.

That is a useful test for evaluating a GEO agency. Mature practitioners should distinguish between confirmed mechanisms, reasonable hypotheses, and experiments.

Why AI Citations Matter

A traditional organic result gives the user a list of sources.

Generative search can synthesize those sources before the user visits them.

That changes the value of a citation.

An AI citation can potentially place a company, publisher, or research source directly alongside an answer at the moment a user is researching a problem.

But citations should not be treated as the only GEO metric.

A company could receive many citations for informational queries that have little connection to revenue. Another brand might receive fewer citations but consistently appear in high-value recommendation and comparison prompts.

A useful GEO measurement framework should therefore distinguish among visibility, citations, brand inclusion, traffic, and business outcomes.

GEO Requires More Than Publishing More Content

One of the easiest ways to sell AI SEO is to promise a large volume of content.

That does not make it a sound strategy.

AI-generated content has made publishing inexpensive. The resulting competitive advantage is less likely to come from producing another 100 generic articles and more likely to come from publishing information competitors cannot easily reproduce.

That can include:

  • Proprietary data
  • Original research
  • First-party experience
  • Expert analysis
  • Customer evidence
  • Unique tools
  • Strong opinions supported by evidence
  • Detailed methodologies

This is where topical authority and brand authority can intersect.

A company that consistently publishes useful information about a subject and earns recognition from credible external sources creates a stronger information environment around its expertise.

GEO and Relevance Engineering

Relevance engineering is another term appearing alongside GEO and AI SEO.

The concept generally expands optimization beyond individual keywords and pages toward improving the relationships among entities, topics, queries, documents, and user needs.

That framing makes sense for modern search.

Search engines have been moving beyond simple keyword matching for years. Generative systems make the limitations of a keyword-only strategy even more obvious.

For a GEO agency, relevance engineering might involve mapping the questions buyers ask, identifying the entities associated with those questions, analyzing which sources repeatedly appear, and determining what information is missing from the client’s existing digital footprint.

The output should still be practical.

Fancy terminology is not a substitute for a measurable strategy.

What About GEO Agencies Like iPullRank and Siege Media?

Companies evaluating GEO services may encounter established search and content agencies discussing AI search.

For example, iPullRank has publicly discussed concepts including relevance engineering and generative search as part of its broader search marketing work. Siege Media is known for content marketing and SEO and has also published material related to AI search and evolving organic discovery.

Those examples illustrate an important point.

There is no single background required to become a GEO agency.

An agency may approach GEO from technical SEO, content marketing, digital PR, analytics, or enterprise search strategy.

So comparing iPullRank, Siege Media, an AI SEO agency, or a specialized GEO consultancy solely by service labels is not particularly useful.

Instead, evaluate the methodology.

Ask each GEO agency what it measures, what it changes, how it validates its assumptions, and how its work connects to revenue.

How to Evaluate a GEO Agency

The AI search market has created plenty of new claims. Buyers need a way to separate useful experimentation from renamed SEO retainers.

Consider asking a prospective GEO agency these questions:

  1. How do you measure AI visibility? The agency should explain which platforms, prompts, competitors, citations, and trends it monitors.
  2. How do you select prompts? A list of random prompts is not a strategy. Prompt selection should reflect customer research, search demand, products, services, and buying journeys.
  3. How does GEO integrate with SEO? Treating SEO and GEO as completely separate disciplines can create duplicated or conflicting work.
  4. How do you improve off-site signals? Ask about digital PR, backlinks, brand mentions, third-party sources, and authority building.
  5. How do you approach technical SEO? A GEO agency should understand crawlability, rendering, structured data, and site architecture.
  6. How do you measure business impact? AI citations are interesting. Pipeline, qualified leads, sales, and revenue are usually more interesting.
  7. Which tactics are proven and which are experimental? This may be the most revealing question. AI search is changing quickly. An agency that claims certainty about every mechanism deserves scrutiny.

GEO Is an Experimental Discipline

Anyone selling GEO in 2026 should be comfortable saying, “We don’t know yet.”

The platforms are evolving. Their retrieval systems can change. Interfaces change. Citation behavior changes. Models change.

That does not mean companies should wait.

It means the work should be approached scientifically.

Create a hypothesis. Establish a baseline. Make a controlled improvement where possible. Measure what changes. Repeat.

For example, a company might discover that competitors receive Perplexity citations from specific industry publications. The response should not automatically be “get links from those websites.”

A better process is to investigate why those sources are being cited.

Are they publishing original research? Do they provide clearer definitions? Are they frequently referenced elsewhere? Do they have stronger topical relevance? Is the information more current?

That distinction turns GEO from a bag of tactics into an optimization process.

How GEO Fits Into an Existing SEO Program

For most companies, generative engine optimization should not require throwing away an existing SEO program.

It should extend it.

Technical SEO creates a discoverable foundation. Content strategy establishes useful coverage. Digital PR increases third-party validation. Structured data provides explicit machine-readable context where appropriate. Analytics establishes measurement.

GEO adds another layer: understanding how that information is represented inside generative systems.

The strongest programs can use insights in both directions.

If a GEO audit reveals that competitors are consistently cited for a topic, that may expose a content or authority gap worth addressing in traditional search.

If SEO research uncovers an emerging commercial query, the company can evaluate how ChatGPT, Gemini, Perplexity, and Google AI Overviews currently answer related questions.

SEO informs GEO.

GEO informs SEO.

The distinction matters for measurement, but the disciplines should not operate in separate rooms.

Should You Hire a GEO Agency?

A GEO agency can make sense when AI-driven search is becoming an important part of your customers’ research process and your internal team lacks the resources to measure or optimize it.

It may be particularly useful if you already have a mature SEO program and need to understand why your traditional organic performance does not translate into equivalent AI search visibility.

But hiring an agency simply because “GEO” is the latest acronym is not a strategy.

Start with the business problem.

Do prospects use AI tools during research? Are competitors appearing when your brand does not? Are Google AI Overviews changing your organic click-through rates? Are third-party sources describing your company accurately? Can you measure referrals and conversions originating from AI-powered search?

If the answers matter commercially, GEO deserves attention.

The Bottom Line

A GEO agency helps businesses improve and measure their visibility across generative and AI-powered search experiences.

The best GEO programs are not shortcuts around SEO. They combine the fundamentals of SEO with stronger content, technical accessibility, structured information, authority building, digital PR, AI visibility tracking, and continuous experimentation.

Whether an agency calls its approach GEO, AEO, LLMO, AI SEO, citation engineering, or relevance engineering matters less than whether the methodology survives scrutiny.

Ask what the agency can measure.

Ask what it can verify.

Ask which assumptions it is testing.

And most importantly, ask how improved AI search visibility connects to the north star metrics your business actually cares about.

Frequently Asked Questions

What does GEO agency mean?

A GEO agency is an agency or consultancy specializing in generative engine optimization. Its work generally focuses on improving a company’s visibility in AI-generated answers and generative search experiences such as ChatGPT, Perplexity, Gemini, Claude, and Google AI Overviews.

What is the difference between a GEO agency and an SEO agency?

An SEO agency primarily works to improve organic search performance, while a GEO agency also evaluates how a brand appears within AI-driven search and generative answers. The disciplines overlap substantially because strong SEO, crawlability, content quality, backlinks, structured data, and authority can support both.

What is an AI SEO agency?

An AI SEO agency may refer to an agency optimizing websites for AI-powered search, an SEO agency using artificial intelligence within its workflow, or both. Because the term has no universal definition, buyers should evaluate the actual services and measurement methodology rather than the label.

Is GEO the same as AEO?

Not exactly. AEO, or answer engine optimization, generally focuses on making content suitable for direct answers. GEO focuses specifically on visibility within generative systems. In practice, many AEO and GEO techniques overlap.

How do you optimize for ChatGPT and Perplexity?

There is no guaranteed method for forcing inclusion in ChatGPT or Perplexity answers. A GEO strategy can improve the information environment around a company through useful content, technical accessibility, credible third-party mentions, digital PR, clear content structure, and authority building. Performance should then be monitored across a controlled set of relevant prompts.

Can schema improve AI search visibility?

Schema can provide structured information that helps search engines interpret a page. However, schema should be treated as one component of technical optimization, not a guaranteed method for obtaining AI citations.

What is a GEO audit?

A GEO audit evaluates a company’s current presence across generative search experiences. Depending on the methodology, it can examine AI citations, brand mentions, competitors, prompt coverage, source domains, content gaps, technical issues, and overall AI search visibility.

What is query fan-out?

Query fan-out describes the process of expanding a user’s question into multiple related searches, subtopics, or information needs. For marketers, it reinforces the value of comprehensive topic coverage rather than optimizing exclusively around one exact keyword.

What should I look for when hiring a GEO agency?

Look for transparent measurement, technical SEO expertise, a defensible content strategy, digital PR capabilities, clear AI visibility tracking, and an experimental methodology. Be cautious of agencies promising guaranteed placement in AI-generated answers or presenting unverified tactics as established ranking factors.

Does GEO replace SEO?

No. GEO is better understood as an extension of modern SEO and digital authority building. Search visibility, technical accessibility, high-quality content, credible backlinks, structured data, and brand authority remain useful foundations as discovery expands into AI-powered search.
