Is it cheaper to build AEO in-house or hire an agency?
▼
For most B2B brands, an agency is significantly cheaper in year one. A lean in-house build — one specialist plus freelance content overflow — costs approximately £150,000–£160,000 in year one once you add recruiting, tooling, and ramp time. A mid-market agency retainer runs £45,000–£110,000 for the same scope, delivered from week one rather than month nine. The cost advantage narrows at later stage when you have budget for three or more specialists and an established content engine.
How long does it take to build an in-house AEO team?
▼
Realistically, 8–14 months from opening the first role to producing measurable AI citations. That includes an average of 4.5 months to hire a specialist, plus 4–9 months of ramp time to develop the prompt fluency and measurement infrastructure needed to move Share of Model. An agency with a working playbook produces first citations in 2–4 weeks and a measurable lift in 3–4 months.
What does a hybrid AEO model look like in practice?
▼
One senior internal lead who owns strategy, brand context, and stakeholder management, paired with an agency that handles technical implementation, content production, citation building, and cross-platform tracking. The internal lead sets direction and holds the agency accountable. The agency provides specialist depth and execution capacity. Year-one cost typically runs £120,000–£180,000 — cheaper than a full in-house team and faster than a solo in-house build.
Can an existing SEO hire do AEO work?
▼
Partly. A strong technical SEO covers the structure and schema work. They typically do not cover multi-engine Share of Model tracking, entity and citation building on third-party sources, or the AI-extraction editorial style that gets content cited verbatim. AEO overlaps with SEO and adds work SEO never required. An existing SEO hire is a head start, not a finished AEO capability.
What is the biggest risk of hiring an AEO agency?
▼
The biggest risk is treating the agency as a hands-off vendor. Brands that do not provide clear briefs, regular reviews, and an engaged internal owner consistently underperform brands that treat the agency as a strategic partner. The agency relationship requires active management — monthly reviews, clear commercial objectives, and an internal owner who can translate business context into agency direction.
When does in-house AEO start to make financial sense?
▼
At later stage, when you have budget for three or more specialists and an established content engine. At that point, the cost-per-output of an in-house team starts to approach the agency cost, and you gain full control and institutional knowledge in return. For most Series A–C B2B brands, the hybrid model delivers better value than either pure model.
How do I know if an AEO agency is credible?
▼
Ask for a citation audit before the engagement starts. A credible agency can show you your current Share of Model across ChatGPT, Perplexity, and Google AI Overviews within the first week. If they cannot run that audit, they cannot tell you where you stand or prove they moved the needle. Also ask for the methodology behind their content-to-citation pipeline and how they track entity authority over time.
