The Three Optimization Disciplines

The search landscape in 2025 requires understanding three distinct but related optimization disciplines:

DisciplineGoalUser BehaviorPrimary Metric
SEORank in search resultsHuman searches → clicks linkRankings, organic traffic
GEOGet cited in AI answersHuman asks AI → reads synthesisAI citations, AI referral traffic
AEOEnable agent task completionHuman delegates to agent → agent actsAgent 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:

Code
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.

Common Mistakes by Profile

Content Businesses

Mistake: Ignoring GEO because "SEO is enough" Reality: AI citations are becoming primary discovery for many users

Mistake: Optimizing for AI instead of humans Reality: AI detects and devalues AI-optimized content

E-Commerce

Mistake: Waiting to see if agents "take off" Reality: 6,900% growth in agent traffic—it's happening now

Mistake: Building AEO without SEO/GEO foundation Reality: Agents discover services through AI search first

SaaS

Mistake: Assuming users will always use their product directly Reality: Agents will increasingly intermediate software interactions

Mistake: Not considering agent authentication early Reality: Retrofitting security is harder than building it in

Local Businesses

Mistake: Ignoring online optimization for "walk-in" business Reality: Local AI queries are growing rapidly

Mistake: Manual-only booking systems Reality: Agent-enabled booking is competitive advantage

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:

  1. Business model: Transactions need AEO; content needs GEO
  2. Audience behavior: Where do your users search?
  3. Technical resources: What can you actually implement?
  4. 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.
