What Is Generative Engine Optimization (GEO)?
Generative Engine Optimization (GEO) is the practice of structuring content to be directly cited and integrated into the answers of AI systems like Google’s AI Overviews , Perplexity, and ChatGPT. Unlike traditional SEO , which aims to rank a URL in a list of search results, GEO focuses on becoming a trusted, authoritative source for the AI model itself.
Why it matters: GEO aims to shape the direct answers users receive, positioning a brand’s data and perspective as the definitive response.
- Objective: To have your brand’s information, data, and narrative featured within the AI-generated summary.
- Focus: Emphasis is on factual accuracy, clear entity definitions, structured data, and verifiable expertise across a topic.
- Mechanism: GEO involves building a comprehensive knowledge graph that an AI can easily parse, understand, and trust.
Authoritative Statement: Generative Engine Optimization is not about ranking links; it is about becoming a foundational data source for AI-generated answers.
Why the Traditional Tofu/Mofu/Bofu Model Fails for AI
The traditional content funnel model, often a 70-20-10 ratio heavy on Top-of-Funnel (ToFu) content, is ineffective for GEO because AI engines detect the resulting knowledge gaps. This volume-based approach creates a wide but shallow foundation of information. AI systems synthesize information from multiple sources and will bypass content that lacks depth, perceived authority, and interconnected proof points.
Key Limitations of the Traditional Model:
- Lacks Depth: A massive ToFu layer without sufficient MoFu and BoFu support is seen by AI as superficial.
- Creates Silos: The stages are often disconnected, preventing an AI from verifying claims made in ToFu content with data from BoFu content.
- Signals Low Authority: Without robust middle- and bottom-funnel content, a brand cannot demonstrate the comprehensive expertise AI requires for citation.
For generative engines, authority isn’t built on volume; it’s built on a deeply interconnected funnel where every stage validates the others.
The Optimal 40-40-20 Content Funnel Mix for GEO
The optimal content funnel for Generative Engine Optimization consists of a 40% ToFu, 40% MoFu, and 20% BoFu mix, creating a balanced, diamond-shaped knowledge structure. This allocation ensures that for every foundational concept introduced, there is substantial content to explain its application, compare alternatives, and prove its value with hard data.
- 40% ToFu (Awareness): Provides clear, concise definitions for core concepts (“What is X?”). Each piece acts as a pillar, internally linked to deeper content rather than existing in isolation.
- 40% MoFu (Consideration): Demonstrates advanced expertise with comparative analysis, implementation guides, and best practices (“How does X compare to Y?”). This layer is critical for establishing differentiation and authority.
- 20% BoFu (Decision): Delivers verifiable proof with dense, data-rich assets like case studies, technical specifications, and pricing data. This content substantiates claims made in the ToFu and MoFu stages.
Practical Implications: Adopting this model requires reallocating resources from high-volume, keyword-driven articles toward creating more in-depth guides, original research, and data-backed case studies that prove expertise.
How to Optimize ToFu Content for AI Citation
To optimize Top-of-Funnel content for AI citation, each article must function as a clear, self-contained, and authoritative answer to a specific question. The goal is to make your definitions the most reliable and easily digestible source for an AI to reference when explaining a foundational topic.
- Answer First: Begin each article with a direct, one-sentence answer to the primary user question.
- Define Entities: Explicitly define all key terms and concepts related to the topic.
- Use Structured Data : Implement schema markup (e.g., FAQ, HowTo) to help machines understand the content’s structure and purpose.
- Link Internally: Connect ToFu definitions to related MoFu comparisons and BoFu proof points to build a verifiable knowledge hierarchy.

The Critical Role of MoFu Content in Establishing GEO Authority
Middle-of-Funnel content is the most critical layer for establishing GEO authority because it demonstrates sophisticated expertise that goes beyond simple definitions. This content provides the nuance, comparisons, and practical guidance that AI engines need to construct comprehensive, multi-step answers for complex user queries.
By thoroughly addressing “how-to,” “compare,” and “best practices” questions, MoFu content signals to an AI that a brand is a consultative expert, not just a dictionary. Assets like detailed guides comparing different AI SEO strategies or step-by-step tutorials are high-value because they directly inform the useful, actionable responses that answer engines aim to provide.
Why BoFu Content Is Essential for AI Verification
Bottom-of-Funnel content is essential for GEO because it provides the verifiable data that AI engines use to substantiate claims made across the entire content funnel. While AI systems are unlikely to cite a product page directly in a general query, they use its data points to validate the trustworthiness of related ToFu and MoFu content.
BoFu Content as Proof:
- Hard Data: Includes technical specifications, performance metrics, and pricing information.
- Case Studies: Offer quantitative results and real-world outcomes that prove a concept’s effectiveness.
- Validation: If a MoFu article claims a method is “40% more efficient,” the BoFu case study provides the evidence, completing the knowledge graph for the AI.

Frequently Asked Questions (FAQ)
Can you use the same content for both traditional SEO and GEO?
Yes, content that is well-researched, factually accurate, and clearly written serves both traditional SEO and GEO. However, for GEO, you must add an extra layer of focus on structured data, explicit entity definitions, and a tightly interconnected internal linking structure across all funnel stages.
How long does it take to see results from a GEO-focused funnel strategy?
Achieving results with a GEO strategy is a long-term investment that typically takes longer than traditional SEO. Becoming a cited source depends on building domain-wide topical authority and aligning with an AI model’s training and data update cycles, which can span many months.
Is video content important for the Tofu/Mofu/Bofu GEO mix?
Yes, video content is increasingly important as AI models become multimodal. Well-structured educational videos with accurate transcripts can serve as powerful ToFu and MoFu assets, making your expertise accessible to AI engines that analyze video and audio data.
Does AI favor ToFu content more than BoFu?
No, AI engines favor comprehensive and authoritative sources, not a specific funnel stage. While an AI is more likely to cite definitional ToFu content for broad questions, it relies on the depth of your MoFu and the verifiable data in your BoFu content to decide if your ToFu content is trustworthy enough to cite.
How do you measure the success of a GEO content funnel?
Success in GEO is measured by tracking brand mentions and citations within AI-generated answers, monitoring referral traffic from AI platforms, and observing improved rankings for long-tail, conversational queries that reflect how users interact with AI assistants.
