What Should a CMO Ask Before Hiring an Agency for GEO or AEO?

To determine what should a CMO ask before hiring a GEO agency, focus on their methodology for multi-platform visibility, citation attribution, and technical data structuring. A qualified partner must explain how they influence Large Language Models (LLMs) and answer engines beyond traditional keyword rankings to ensure your brand remains relevant in AI-generated responses.

TLDR

• GEO (Generative Engine Optimization) focuses on visibility within AI models like ChatGPT and Perplexity.

• AEO (Answer Engine Optimization) prioritizes providing concise, direct answers to specific user queries.

• CMOs must distinguish between agencies offering "AI content spam" and those providing strategic entity-based optimization.

• Success is measured by citation share and brand sentiment in AI responses, not just blue-link rankings.

Understanding the New Search Frontier: GEO vs. AEO

As search behavior shifts from scrolling through lists of links to reading synthesized answers, CMOs face a new challenge. Traditional Search Engine Optimization (SEO) is no longer sufficient. To maintain market share, brands must now master Generative Engine Optimization (GEO) and Answer Engine Optimization (AEO).

GEO (Generative Engine Optimization) is the process of improving a brand’s visibility and citation frequency within generative AI responses. This includes platforms like ChatGPT, Google Gemini, and Perplexity. Unlike traditional search, which ranks pages, GEO aims to influence the training data and live-web retrieval processes that these models use to form answers.

AEO (Answer Engine Optimization) is a subset of search marketing focused on providing the single "best" answer to a specific question. It is highly related to Featured Snippets in traditional Google Search (Search Engine Results Pages, or SERPs), but it is now critical for voice assistants and AI chat interfaces that provide one primary response.

While SEO focuses on clicks, GEO and AEO focus on mentions, recommendations, and brand authority within a black-box environment. This shift requires a different set of skills from an agency partner, involving deeper technical data knowledge and a sophisticated understanding of the publisher ecosystem.

How to Evaluate GEO Agencies

When vetting a potential AI search strategy partner, the first hurdle is separating those who use AI to write content from those who understand how to optimize for AI engines. Many agencies rebranded overnight. To perform a real evaluation, a CMO must look at their technical approach to "entity clarity."

An entity is a well-defined object or concept—like your brand or product—that an LLM (Large Language Model) can identify. Ask the agency how they map your brand’s entity across the web. If they cannot explain how they use Schema.org markup, Knowledge Graph nodes, or third-party citations to solidify your brand’s identity, they are likely just a traditional SEO firm in a new coat of paint.

Evaluating Data and Tools

Ask about their tech stack. Traditional tools like Semrush or Ahrefs are useful for SERP data, but they do not track citation share in Perplexity or recommendation frequency in ChatGPT. A sophisticated agency should have a framework for measuring "Share of Model" or "Citation Breadth."

How to evaluate GEO agencies effectively involves asking for a deep dive into their attribution model. Since AI engines often do not provide traditional click-through data (CTR) in a clean dashboard, the agency must demonstrate how they correlate AI mentions with brand lift or assisted conversions.

Essential AEO Agency Questions for the C-Suite

AEO is more tactical than GEO. It requires a rigorous focus on structure and brevity. When interviewing a team for answer engine optimization services, you need to know how they prioritize which questions to answer.

AEO Agency Questions to Ask:

1. How do you identify the "unanswered questions" in our category that AI engines are currently hallucinating or ignoring?

2. What is your process for structuring data so that it is "instantly extractable" by a scraper or an LLM?

3. How do you handle the trade-off between a long-form, high-conversion landing page and a concise, AEO-friendly summary?

4. Which markup types (JSON-LD, Microdata) do you prioritize for our specific product category?

An AI search strategy partner should be able to show how they have helped brands win position zero or become the primary source for "how-to" and "what is" queries in the past.

Prioritizing Ecommerce GEO Support

For retail and DTC (Direct-to-Consumer) brands, the stakes are higher. AI engines are increasingly acting as personal shoppers. If a user asks, "What is the most durable waterproof hiking boot for wide feet?", you want your product to be the first recommendation.

Ecommerce GEO support requires a twin-track approach. First, the agency must optimize your own site—product descriptions, technical specs, and verified reviews. Second, they must influence the "authority layer" of the internet. This includes top-tier publishers, Reddit, and niche review sites. LLMs often trust these third-party sources more than a brand's own marketing copy.

The Role of Business Teams

This work is rarely owned by a single team. A successful GEO strategy requires:

• SEO/Web Teams: To handle the technical schema and on-site architecture.

• Content/PR Teams: To manage the external ecosystem and ensure brand mentions appear on high-authority publisher sites.

• Product Teams: To provide the granular data points (weight, materials, manufacturing origin) that AI engines use to compare products.

Common mistakes include focusing solely on the brand’s own blog. In the GEO world, what The New York Times (https://www.nytimes.com/) or a specialized trade publication says about you is often more influential than what you say about yourself.

Measuring Success in the GEO Era

CMOs should be wary of agencies that promise "Number 1 rankings." In AI search, there is no single "Number 1." Every user prompt generates a unique response. Instead, demand these performance indicators:

• Citation Frequency: How often is your brand cited as a source or recommended in a list?

• Sentiment Alignment: When the AI mentions you, is the sentiment accurate to your brand positioning?

• Entity Dominance: Does the AI correctly identify your brand's core attributes (e.g., "affordable luxury" vs. "budget-friendly")?

• Referral Traffic via AI: Tracking traffic from domains like chatgpt.com or perplexity.ai in your analytics.

A Concrete Strategy Scenario

Imagine an ecommerce brand sells high-end espresso machines. A traditional agency might try to rank for "best espresso machine." A GEO-focused agency will instead ensure that when a user asks an AI, "Which espresso machine has the most consistent steam pressure for latte art?", the AI cites a specific white paper on the brand's site or a review from a trusted coffee publisher. This is the difference between casting a wide net and being the specific answer at the bottom of the funnel.

FAQ: what should a CMO ask before hiring a GEO agency questions

What are generative engine optimization services?

These services focus on making a brand visible and recommendation-worthy within AI chat interfaces like ChatGPT, Gemini, and Perplexity by optimizing technical data and third-party mentions.

How do GEO agencies differ from traditional SEO agencies?

Traditional SEO focuses on ranking in list-based search results, while GEO agencies focus on being included in the synthesized, narrative answers generated by AI models.

Why is citation share important for CMOs?

Citation share measures how often an AI engine credits your brand as a source, which directly influences brand authority and user trust in a zero-click environment.

What is the most common mistake when hiring for AEO?

The most common mistake is hiring an agency that focuses only on "quantity of content" rather than the "extractability" and structure of the information for AI scrapers.

How does an AI search strategy partner impact ROI?

They drive ROI by ensuring your brand is present at the new point of discovery—AI answers—where high-intent shoppers are increasingly going instead of traditional search engines.
