Choosing an AI Search Model: What Every CMO Needs to Know

We’ve already covered what GEO execution actually requires and introduced the three operating models for AI search. Now let’s go deeper on each one — the real advantages and the real challenges. 

Building an Internal GEO Team 

What Are the Advantages of an Internal GEO Team? 

The greatest advantage is proximity to the business. 

Internal leaders understand the organization’s customers, products, politics, technologies, approval processes, risk tolerance, and history. They can build long-term institutional knowledge and connect GEO directly to company strategy. 

For organizations where generative discovery is central to the business model, GEO may eventually need to become a durable internal capability. 

What Are the Challenges of Building GEO Internally? 

The first challenge is talent. 

A complete GEO capability may require knowledge across SEO, content, PR, analytics, development, data, brand, and AI systems. Finding that range of experience in one person is extremely difficult. Building it through a team requires greater investment. 

The second challenge is capacity. 

The organization must create its AI search strategy while also evaluating tools, developing measurement, training teams, running experiments, monitoring platform changes, and executing recommendations.  

The third challenge is authority. 

A GEO leader may identify changes needed across communications, editorial, development, analytics, and brand. If that leader lacks the authority or executive support to influence those functions, the role can quickly become an advisory position with little ability to create change. 

The Reality of Bringing GEO In-house 

Building internally means building more than a team. It means building the surrounding system that enables the team to operate — the strategy, tooling, measurement infrastructure, cross-functional processes, and organizational alignment. That is a substantial undertaking, and many organizations underestimate the time and investment required before meaningful results will begin to emerge. 

Hiring GEO Contractors 

What Are the Advantages of GEO Contractors? 

Contractors offer flexibility. 

Unlike tapping into internal resources, a company can hire the exact expertise it needs without immediately adding permanent headcount, agencies offer a similar benefit. 

A technical SEO contractor can investigate crawling or rendering problems. A digital PR specialist can focus on earned authority. A data engineer can build a measurement pipeline. A content strategist can develop new editorial structures. 

Contractors are particularly useful for defined projects, temporary capacity gaps and fractional strategic leadership. They can supplement an existing program, but they are rarely sufficient to build one. 

What Are the Challenges of GEO Contractors? 

Coordination is the biggest risk. 

Contractors generally operate within the boundaries of their assignments. They may not be responsible for understanding the recommendations produced by the other specialists working around them. 

The PR contractor and SEO contractor are optimizing for different outcomes. While the analytics contractor is designing measurement around the data that is easiest to obtain. 

Each of their recommendations will be reasonable on its own. However, someone must determine how the pieces work together, which work should come first, and how success will be evaluated collectively.  

Without these conditions, the contractor model often creates fragmentation and makes it difficult to translate work into integrated, measurable outcomes. 

When Are GEO Contractors the Best Choice? 

Leveraging contractors successfully requires more than hiring the right specialists — it requires a leader with a clear strategy, the authority to enforce it, and the tools to measure progress. 

That surrounding system doesn’t come with the contractors. It has to already exist. And building it carries the same requirements as building an internal team: time, investment, and organizational alignment that most companies are still working to establish. 

Hiring a GEO Agency 

What Are the Advantages of a GEO Agency? 

An agency’s most obvious advantage is access to a larger pool of expertise and capacity. A capable GEO agency may bring together SEO professionals, content strategists, PR leaders, data scientists, analysts, developers, brand strategists, and change leaders. 

That creates several potential benefits. 

1. Integrated expertise and accountability. GEO crosses disciplines that have historically operated separately. An integrated agency can consider how technical accessibility, owned content, earned authority, brand signals, customer experience, and measurement affect one another. That integration establishes accountability through one primary partner, manages coordination, dependencies, and progress reports. This is especially valuable when the agency teams already know how to work together.
2. Faster mobilization. Building an internal capability requires hiring, onboarding, tool selection, process development, and stakeholder alignment. An agency may already have the people, workflows, tools, and research processes in place. This can help an organization move from exploration to structured execution more quickly.
3. Greater execution capacity. GEO programs create work. Organizations may need technical audits, content inventories, prompt research, competitive analysis, editorial development, digital PR, analytics, experimentation, reporting, and training. An internal leader may know what needs to happen but lack the resources to complete it, while an agency can provide additional capacity without requiring the company to hire an entire department.
4. Stronger expertise and capability from day one. An internal team builds knowledge from one organization’s experience. An agency builds it across industries, platforms, technology stacks, and customer journeys — and reinvests that learning into tools, data infrastructure, and research that individual clients would struggle to justify on their own. The result is that a client doesn’t just gain a partner. They gain access to a baseline of capability, pattern recognition, and infrastructure that would take years to develop internally — without personally funding every component of it.
5. Organizational support. A capable agency can also help educate internal departments, translate recommendations into the language of each function, and support workflow changes. This is an important advantage, but it is one element of a broader agency value proposition.

What Makes a Good GEO Agency Partner? 

The greatest risk in the agency model is not the model itself — it is choosing the wrong partner. Not every agency that offers GEO services can guarantee the integration, structural accountability, or business understanding that makes those services effective. 

That makes partner evaluation as important as the decision to hire an agency at all. The right agency will have a clear answer for how it coordinates across disciplines, how it builds understanding of your business, and how it measures and reports progress. Those questions, and the quality of the answers, are what separate agencies equipped to lead a GEO program from those still developing that capability. 

When Is a GEO Agency the Best Choice? 

The conditions that make the internal and contractor models difficult are, in most cases, precisely the conditions that make an agency the right choice — limited internal expertise, constrained capacity, disciplines that need to be coordinated, and a program that requires both strategy and execution from the start. It is also the natural fit for organizations that haven’t yet established tools and measurement, need to move quickly, or want one partner accountable for the integrated program. 

For most organizations at the beginning of a GEO program, that description will feel familiar. The agency model doesn’t just fill a gap. It provides the surrounding system that the other models require but rarely include.
