# AEO vs GEO vs SEO

Three related but distinct disciplines. Knowing the difference clarifies what to optimize for.

## SEO (Search Engine Optimization)
**Goal:** Rank in Google's blue-link search results.

**Optimize for:**

- Keywords matching searcher intent
- Backlinks from high-authority domains
- Page-level technical SEO (Core Web Vitals, schema, etc.)
- Click-through rate from SERP

**Success metric:** Organic traffic, ranking position, CTR.

**Status:** Mature discipline. Still relevant, especially for high-intent commercial queries.

## AEO (Answer Engine Optimization)
**Goal:** Become the source for direct answers in featured snippets, AI Overviews, and conversational AI responses.

**Optimize for:**

- Direct question-answer formatting
- Schema markup that aids extraction (FAQ, HowTo, DefinedTerm)
- Structured content with clear headings
- Authority signals (E-E-A-T)

**Success metric:** Featured snippet appearances, AI Overview presence, citation in AI answers.

**Status:** Active discipline since ~2020 (snippets) accelerating with AI Overviews.

## GEO (Generative Engine Optimization)
**Goal:** Get cited by generative AI search engines. ChatGPT, Perplexity, Claude, Gemini.

**Optimize for:**

- Citation-worthy content (factual, current, authoritative)
- Schema markup for entity recognition
- Backlinks from sources AI trusts
- Presence on aggregator and community sources (G2, Reddit, YouTube, industry pubs)

**Success metric:** Citation rate, AI mention frequency, share of voice in AI responses.

**Status:** Emerging discipline (since ~2023). Where most attention is shifting in 2026.

## How They Relate

|  | SEO | AEO | GEO |
| --- | --- | --- | --- |
| Target | Google rankings | Featured snippets, AI Overviews | ChatGPT, Perplexity, Claude, Gemini citations |
| Click model | Click-through | Often zero-click | Mostly zero-click |
| Author signals | Important | Very important | Critical |
| Schema markup | Helpful | Essential | Essential |
| Backlinks | Critical | Important | Important |
| Update cadence | Quarterly | Monthly | Weekly during fast cycles |

## What to Optimize For
In 2026, the answer is **all three**. They share more in common than they differ:

- High-quality, structured content
- Strong author and brand signals
- Authoritative backlinks
- Comprehensive topical coverage

The differences are mostly tactical: AEO and GEO weight schema, structure, and citation-worthy formatting more heavily; SEO weights raw click-through and ranking signals more.

If you have to pick one to lead with, **GEO** has the highest growth trajectory. search behavior is shifting fastest there. But don't abandon traditional SEO; AI engines often crawl and weight Google-ranked pages.
