Fractional Head of GEO for Agencies

A fractional head of GEO leads generative engine optimization for your agency on a part-time basis. The work covers what a model says about a client when it writes an answer from scratch, and that depends on far more than the client's website.

I led AEO strategy at W3whiz and managed 5 engineers building AI-search tooling at Search Atlas. This seat applies that background to your clients, so you get GEO direction without hiring a permanent executive.

Where the work differs from AEO leadership

GEO leadership starts upstream. An AEO owner picks prompts and structures pages so one answer can lift a quote. A GEO owner asks what the model knows about the brand at all: whether the descriptions agree, whether credible outside sources exist, and whether the client's content gives the model something accurate to repeat.

A common GEO failure is a brand described inconsistently across the web, or hardly described outside its own domain. If your focus is the citation side, the fractional head of AEO seat is the match.

What a fractional head of GEO owns

The seat is accountable for the plan and the discipline behind it. Mentions in generated text cannot be guaranteed, so I do not treat them as the deliverable.

Listen for the failure modes in client conversations. A model that names a competitor instead. A model that describes a service the client dropped two years ago. A model that says nothing about the client at all. Each has a different cause, and the seat's job is to sort them before the agency promises a fix. The post on AI answer engines gives context on how these systems choose what to say.

• Entity clarity: one consistent description of the client across its site, profiles and structured data.
• Corroboration: which outside sources describe the client, and where missing coverage is limiting what models say.
• Synthesis-ready content: pages that state facts plainly enough to be reused without distortion.
• Measurement discipline: how responses are sampled, logged and interpreted.
• Scope boundaries: which findings belong to the agency and which belong to PR or the client's own team.

Measuring what models say

Responses vary by model, by phrasing and over time, and a single change cannot be isolated. Measurement stays immature, and I plan around that.

For each client I define a set of questions, run them across the models that matter, and record whether the brand appears, how it is characterized, and whether the characterization is accurate. A wrong or outdated description is often the most useful result, since it points at a specific fix. Your team learns to report observations and to skip causal claims it cannot back up. The guide to generative engine optimization covers the concepts.

How the engagement runs inside an agency

It is a standing leadership seat scoped to your clients and team, with the time agreed on a call. I set the method, review the entity and corroboration analysis your team produces, and join client conversations that need someone to explain how generative search changes the picture.

GEO touches brand, PR and content as much as SEO, so I help you decide where the agency's scope ends. Sometimes the answer is a content and entity cleanup. Sometimes it is a conversation about outside coverage that your agency cannot produce, and I will say that directly.

I am also available for the awkward conversation where a client expects GEO to behave like link building. It does not, and the expectations are easier to set at the start than to repair later.

Starting with one or two accounts

Begin small. For one or two accounts, your specialists compare how the brand is described across its own properties, sample model answers, and list the outside sources that seem to shape them.

The output is a short findings list: inconsistencies to correct, content to rewrite, and coverage gaps that need a long-term plan. Some findings sit outside an SEO retainer, such as reputation or partner listings, and I mark them so the agency does not absorb work it cannot deliver. If you only need a diagnosis, a GEO consultant review is the smaller step.
