How to Choose a GEO Agency: Criteria and Questions to Ask

As AI-powered search and answer engines spread, brands' visibility strategies are changing too. Ranking high on Google is no longer the only goal; being represented accurately in ChatGPT, Gemini, Perplexity and similar generative AI systems, being used as a source, and having brand information passed on reliably all matter now.

With this shift, the question "How do you choose a GEO agency?" is coming up more and more often.

GEO, short for Generative Engine Optimization, is the optimization approach that aims to make brands more visible, more understandable and more trustworthy in generative AI systems.

The right GEO agency does more than produce content. It analyzes the brand's digital assets, information architecture, content structure, authority signals and technical accessibility together, along with how different AI systems evaluate information.

The wrong choice, on the other hand, can leave your business buying reports full of new terminology without making any real progress on "AI visibility".

That is why, before buying GEO services, you need to carefully assess the agency's approach, its measurement method, how it connects GEO with SEO knowledge, and its real expertise.

What Is GEO?

GEO is the optimization discipline that aims to help generative AI systems better understand brands and content, find them trustworthy, and reference them more often in relevant user queries.

In classic SEO, one of the core goals is to gain visibility on search engine results pages.

In GEO, the goal is broader.

A brand may want to:

• be mentioned in AI answers,
• be treated as a trustworthy source,
• be represented with accurate information,
• be associated with its product or service categories,
• build authority in its area of expertise.

So GEO is not just a content production process.

Technical structure, content quality, brand authority, source credibility and semantic consistency all need to be handled together.

To understand this field in more depth, reading a detailed GEO guide makes the core concepts easier to grasp before you choose an agency.

What Does a GEO Agency Do?

A professional GEO agency starts by analyzing the brand's current digital visibility.

This analysis is not limited to the website.

The agency generally evaluates:

• information about the brand available online,
• the semantic structure of the website,
• the expertise level of the content,
• citability,
• brand mentions,
• visibility in third-party publications,
• technical SEO infrastructure,
• entity signals,
• content clusters,
• brand authority.

A GEO strategy is then built on this data.

SEO fundamentals matter as much as GEO knowledge in this process, because a large share of the content AI systems access, crawl and use still comes from the classic web ecosystem.

That is why strong GEO projects benefit greatly from the approach of an experienced SEO expert.

What Is the Difference Between GEO and SEO?

SEO and GEO are not two completely independent fields.

SEO focuses on gaining visibility in search engines, while GEO concentrates more on visibility and citability in generative AI systems.

SEO mostly focuses on:

• technical accessibility,
• indexing,
• keyword visibility,
• organic traffic,
• backlinks,
• content optimization.

GEO adds questions like these:

• How do AI systems describe the brand?
• Which topics is it associated with?
• Is there strong enough content to be used as a source?
• Is the information about the brand online consistent?
• How visible is the brand in third-party sources?

This is why GEO work is usually built on a strong SEO foundation.

Reading a comprehensive SEO guide to understand the classic search side makes it clearer why GEO cannot be treated as completely separate from SEO.

Define Your Goals Before Choosing a GEO Agency

Before buying GEO services, you need to clarify what your brand wants to achieve.

Your goal might be to:

• increase brand awareness in ChatGPT-like systems,
• be associated with specific service categories,
• increase product visibility in AI recommendations,
• be used as a source in your area of expertise,
• ensure your brand information is represented accurately,
• grow AI referral traffic,
• increase brand mentions.

Each of these goals requires a different strategy.

For a strong B2B brand, for example, topical expertise and authority content may be the priority.

For an e-commerce brand, consistency of product information, category structure and third-party references may matter more.

So it is not enough to open the agency meeting with only:

"We want to show up in ChatGPT."

Instead, set clearer goals such as:

"We want AI systems to recommend our brand for specific commercial queries and associate it with the right sources."

How Can You Tell a Good GEO Agency?

Because GEO is such a new field, you need to be more careful than with classic digital marketing services when choosing an agency.

Today, many companies can claim to offer GEO services.

But there is a big difference between using the concepts and having real expertise.

It does not treat GEO as content production alone

A good GEO agency does not just write long blog posts.

It also evaluates:

• information architecture,
• the brand's entity structure,
• source credibility,
• third-party mentions,
• site structure,
• content clusters,
• brand consistency

together.

It builds the SEO–GEO relationship correctly

A GEO approach completely cut off from SEO usually falls short.

If your website is technically inaccessible, disorganized or low in authority, producing content labelled "GEO" may not be enough.

A good agency treats SEO and GEO not as alternatives but as complements.

It explains its method instead of showing off new terms

The GEO field uses many new concepts, such as:

• LLM,
• entity,
• RAG,
• vector search,
• knowledge graph,
• prompt visibility,
• AI citation.

A comprehensive AI glossary can help you understand what these concepts mean.

But an agency using these terms is not, on its own, a sign of expertise.

What matters is whether it can explain which method is used to produce which result.

Work With a Team That Has GEO Expertise

In GEO projects, it may not be enough for the person leading the strategy to have only content production experience.

A good GEO expert should be able to evaluate:

• the basic logic of search systems,
• how AI models use information,
• entity structures,
• brand authority,
• content strategy,
• source credibility

together.

When meeting an agency, always ask who will manage your project.

A senior expert being in the sales meeting does not necessarily mean the same person will be involved once the project starts.

That is why questions like:

"Who will manage the project?"

"Who will build the strategy?"

"Who will interpret the reports?"

are very important.

Assess the GEO Agency's Content Strategy

Content is usually at the center of GEO projects.

But content strategy is not just publishing more articles.

A proper content strategy should determine the topics in which the brand needs to build expertise.

Content should be:

• comprehensive,
• verifiable,
• clear,
• up to date,
• informed by expert opinion,
• semantically strong.

In generative AI systems especially, trustworthy and comprehensive sources are gaining value over superficial content.

So ask the agency:

"What do you do differently when producing content for GEO?"

If the answer is only "we write AI-friendly content", that is not enough.

Ask About Entity and Brand Authority Work

One of the key areas of GEO is the entity approach.

A system evaluates your brand not just as a name, but through connections such as:

• which sector it operates in,
• which products or services it offers,
• which people it is associated with,
• which topics it is an expert in.

That is why consistent brand information across the web matters.

Ask whether the agency works on:

• brand mention analysis,
• person and company entity structure,
• strengthening "about us" pages,
• expert profiles,
• citable content,
• third-party references.

Review the GEO Agency's Backlink and Digital PR Approach

In GEO work, references from third-party sources are very valuable.

That is why you need to go beyond the classic backlink approach.

Instead of just acquiring links, these factors should be considered:

• brand mentions,
• contextual relevance,
• the publication's credibility,
• industry relevance,
• source authority,
• the context in which the brand is mentioned.

For example, a brand appearing with expert commentary in a trustworthy publication in its field can be a much stronger signal than an ordinary backlink.

So ask the GEO agency:

• Do you do digital PR?
• Do you track brand mentions?
• How do you increase visibility in third-party sources?
• How do you distinguish between links and mentions?

Review the GEO Agency's References

When evaluating an agency's past projects, do not look only at client logos.

Review the sectors and project variety of the brands on the agency's references page.

More importantly, ask:

• What work was done on this project?
• Which metrics were tracked under GEO?
• What changed in AI visibility?
• Did brand mentions increase?
• Did AI-driven referral traffic grow?

Because GEO is a new field, not every agency will have years of case history.

So methodology and measurement approach may matter more than references.

Look at Case Studies

A professional GEO agency should, where possible, present case studies backed by real results.

A good GEO case study may include:

• starting visibility,
• core problems,
• the strategy applied,
• content changes,
• third-party mention work,
• changes in visibility within AI answers,
• changes in referral traffic.

If a case study contains only general statements like:

"AI visibility increased."

it may not be enough.

It is important that the agency can explain its measurement method.

How Is GEO Success Measured?

Measurement is one of the hardest parts of GEO.

In classic SEO there are more established metrics, such as:

• rankings,
• clicks,
• traffic,
• conversions.

On the GEO side, metrics like these can be used:

• number of AI mentions,
• number of AI citations,
• brand visibility,
• findability for specific queries,
• rate of being used as a source,
• AI referral traffic,
• growth in branded search,
• brand awareness indicators.

But the key point is this:

No GEO agency can directly control how every AI system works.

So be cautious about claims like "100% visibility guarantee".

Beware of Agencies That Guarantee AI Visibility

As in SEO, firm guarantees are a major red flag in GEO.

Statements such as:

"We'll definitely get you into ChatGPT."

"You'll be visible in every AI system within 30 days."

are not realistic.

AI systems' answers can vary depending on:

• the model,
• the query,
• the time,
• the user's context,
• the data sources.

That is why a professional agency talks about strategies that increase the likelihood instead of guarantees.

What Questions Should You Ask a GEO Agency?

It helps to ask these questions in agency meetings.

How do you build your GEO strategy?

This shows whether the agency offers a standard package or a custom strategy.

Which AI platforms do you track?

You can find out whether ChatGPT, Gemini, Perplexity and other systems are included in measurement.

How do you measure success?

An approach tied to a single metric such as a "visibility score" may not be enough.

How do you combine SEO and GEO work?

This question is important for understanding the agency's core SEO knowledge.

Is content production included in the service?

Content usually plays a central role in GEO projects.

Do you do digital PR?

Brand visibility in third-party sources is very important.

What Should GEO Reports Include?

A good GEO report should not be just a dashboard showing dozens of metrics.

The report should answer:

• In which AI systems did visibility increase?
• In which queries is the brand mentioned?
• Which content is being used as a source?
• Which competitors get mentioned more often?
• Which content areas have gaps?
• What work will be done next month?

These reports should make decision-making easier.

Look at the GEO Agency's Own Visibility

The brand visibility of an agency that claims to offer GEO services is also an evaluation criterion.

For example, you can check whether it:

• produces content on AI and GEO,
• publishes original research on the topic,
• is referenced in its own field.

But having made itself visible is not enough on its own either.

What matters more is whether it can apply a similar systematic approach to client projects.

How Do You Identify the Best GEO Agency?

"Best" is relative in GEO as well.

An agency that is strong for one brand may not suit another.

Businesses that want to compare options can use best GEO agency lists as a starting point.

But it is healthier to make the final decision based on these criteria:

• strategic approach,
• SEO foundation,
• content quality,
• measurement system,
• digital PR experience,
• references,
• project team.

SEO Agency or GEO Agency?

These two services are not alternatives to each other.

GEO work is in most cases built on a strong SEO foundation.

So it may not be right for a website with serious problems on the classic organic search side to invest only in GEO.

Technical SEO and content infrastructure should be strengthened first.

Here, the How to Choose an SEO Agency guide, written for evaluating classic agencies, also contains many shared criteria you can use when choosing a GEO agency.

Compare SEO Agencies Too

Many companies offering GEO services also provide SEO services.

So it is useful to review the candidate agencies' track record on the classic SEO side as well.

To see different options in the Turkish market, you can look at the Best 10 SEO Agencies or the broader Best 15 SEO Agencies comparisons.

But what matters here is not list order; it is how well the agency's expertise matches your project.

Is the Best SEO Agency Also Good at GEO?

Not always.

A company may be very strong in classic SEO but not yet have a mature GEO methodology.

Similarly, a team positioned only around GEO may not have strong technical SEO experience.

So when evaluating the best SEO agency, it now helps to add this question:

"How ready is the agency for the AI-powered search ecosystem?"

Can GEO and Performance Marketing Work Together?

GEO is not performance advertising.

But performance marketing data can be used to understand user behavior.

For example:

• which products attract more interest,
• which messages drive higher conversion,
• which landing pages perform better

can provide valuable input for GEO and content strategy.

That is why, for large brands, a holistic digital growth approach can be more effective than a channel-by-channel one.

GEO Agency or Digital Marketing Agency?

Some companies may want GEO services only.

Others may want to manage services such as:

• SEO,
• GEO,
• content,
• digital PR,
• Google Ads,
• Meta Ads

together.

In that case, an agency offering a full range of services can be an advantage.

When evaluating options in Turkey, you can review different agencies' service scopes through best digital marketing agency comparisons.

But offering many services does not automatically mean expertise.

You need to ask about the team capacity in each service area separately.

How Are GEO Agency Prices Determined?

GEO service pricing is not yet standardized.

The main factors that affect price are:

• brand size,
• content volume,
• existing SEO infrastructure,
• number of target topics,
• industry competition,
• digital PR needs,
• number of international markets,
• reporting scope.

In some projects, consulting alone may be enough.

Others require much more comprehensive work, including content, PR and technical implementation.

So do not compare proposals only on monthly fees.

Should You Be Wary of Cheap GEO Services?

Price alone is not a measure of quality.

But very low-priced GEO packages often show problems such as:

• automated content,
• superficial AI visibility reports,
• no real strategy,
• no third-party mention work,
• neglected SEO infrastructure.

Always ask what packages like "10 AI-friendly articles + a GEO report" actually include.

The Most Common Mistakes When Choosing a GEO Agency

Thinking GEO is only about ChatGPT visibility

GEO covers a much broader ecosystem.

Dropping SEO entirely

GEO benefits from a strong SEO foundation.

Being impressed by new terms alone

Technical jargon is not a sign of expertise.

Believing guarantees

No agency can control AI answers.

Focusing only on content production

Brand authority and third-party sources matter too.

Starting without a measurement system

Success criteria should be defined from the start.
