The Three Optimization Disciplines
The search landscape in 2025 requires understanding three distinct but related optimization disciplines:
| Discipline | Goal | User Behavior | Primary Metric |
|---|---|---|---|
| SEO | Rank in search results | Human searches → clicks link | Rankings, organic traffic |
| GEO | Get cited in AI answers | Human asks AI → reads synthesis | AI citations, AI referral traffic |
| AEO | Enable agent task completion | Human delegates to agent → agent acts | Agent transactions, task success rate |
Each serves a different user journey. The question isn't which is "best"—it's which combination fits your business.
Quick Decision Matrix
Answer these questions to find your starting point:
Question 1: What's Your Primary Value Proposition?
A) Information and content (blog, news, documentation, research) → Prioritize: SEO + GEO
B) Transactions and services (e-commerce, bookings, SaaS) → Prioritize: SEO + GEO + AEO
C) Lead generation (B2B services, consulting, agencies) → Prioritize: SEO + GEO
Question 2: How Do Your Users Currently Find You?
A) Primarily Google search → Maintain SEO, add GEO gradually
B) Mix of search + AI assistants → Balance SEO and GEO equally
C) Direct/referral with growth goals → Invest in SEO and GEO for new acquisition
Question 3: Do Users Perform Actions on Your Site?
A) Mostly consume content → SEO + GEO sufficient
B) Complete transactions (purchases, bookings, forms) → Add AEO to the mix
C) Use your product/service daily → Prioritize AEO for workflow integration
Question 4: What Are Your Technical Resources?
A) Limited (small team, no developers) → Focus on content-based SEO + basic GEO
B) Moderate (some development capacity) → SEO + GEO + schema markup + llms.txt
C) Strong (dedicated engineering) → Full SEO + GEO + AEO with MCP implementation

The Cumulative Model
SEO, GEO, and AEO build on each other—they're not alternatives:
Layer 3: AEO
├── MCP/API interfaces
├── Agent authentication
├── Transaction enablement
└── Builds on: SEO + GEO
Layer 2: GEO
├── Citable content structure
├── AI crawler access
├── E-E-A-T signals
└── Builds on: SEO
Layer 1: SEO
├── Technical foundation
├── Content optimization
├── Authority building
└── Foundation for all
Never skip SEO for GEO. A site with poor technical SEO will struggle with AI crawlers too.
Never skip GEO for AEO. If AI systems don't understand your content, agents won't know you exist.

Quick Reference: When to Prioritize What
Prioritize SEO When:
- New site or domain
- Poor technical foundation
- Low organic traffic
- Keyword rankings declining
- Core pages not indexed
Prioritize GEO When:
- Strong SEO but flat traffic
- Audience using AI assistants
- Competitors cited in AI responses
- Original content/research to promote
- Want to be authority source
Prioritize AEO When:
- Transactional business model
- Competitors enabling agent interactions
- Users request automation capabilities
- Strong technical resources
- SEO and GEO foundations solid
Deprioritize AEO When:
- Pure content/information business
- Very limited technical resources
- No user transactions
- SEO/GEO foundations weak
- Audience not using AI agents
Conclusion
The optimal SEO/GEO/AEO mix depends on:
- Business model: Transactions need AEO; content needs GEO
- Audience behavior: Where do your users search?
- Technical resources: What can you actually implement?
- Competitive landscape: What are competitors doing?
For most businesses in 2025:
- SEO remains foundation (35-50% effort)
- GEO is increasingly critical (30-45% effort)
- AEO matters for transactional businesses (10-35% effort)
The disciplines are cumulative. Build from SEO → GEO → AEO, never skip layers, and allocate based on where your users are heading—not just where they are today.
