The AEO foundation

Built for clarity, then execution.

Four entry points define the discipline, from the basic concept to the infrastructure layer that lets agents complete real tasks.

01

Definition

Understand what AEO is, why it matters, and the principles that guide it.

02

Positioning

Map your visibility and relevance across SEO, GEO, and agent engines.

03

Execution Layer

Implement the protocols, schemas, and patterns that enable reliable execution.

04

Implement AEO

Operationalize AEO across your systems, content, and workflows.

Core distinction

Read layer versus execution layer.

Most market discussion stops at visibility in AI answers. AEO extends further: agents must be able to understand your site and act through it with low ambiguity.

FAQ

Frequently asked questions.

What is Agent Engine Optimization?

Agent Engine Optimization (AEO) is the discipline of making websites, APIs, and digital infrastructure readable, trustworthy, and actionable for autonomous AI agents.

How is AEO different from SEO and GEO?

SEO targets rankings in search results. GEO targets citations in AI-generated answers. AEO adds the execution layer, where agents can complete tasks through your infrastructure.

What is the execution layer?

The execution layer is the part of your digital presence that allows AI agents to perform actions through APIs, deterministic endpoints, and protocols like MCP and UCP.

How do I measure AEO success?

Track AI citation rates, agent traffic volume, endpoint completion rates, and agent-driven conversions alongside traditional search metrics.
