What is AEO, GEO & LLMO?

A clear, jargon-free explanation of the new discipline that's changing how brands get discovered.

The problem in 30 seconds

Imagine a customer asks ChatGPT: "What's the best CRM for small businesses?" If your brand isn't mentioned in the answer, you've lost a potential customer — and you never even knew about it.

That's exactly the problem AEO solves. When people stop clicking on links and trust AI answers instead, your brand needs to be inside that answer.

This isn't just about ChatGPT. Google also generates AI answers directly in its results (called "AI Overviews"). Perplexity, Claude, Mistral's Le Chat — they all work this way. Chapter 2 explains these terms in detail.

Three names, one idea

The industry uses three different terms, but they all aim at the same goal: make your brand visible when AI answers questions.

AEO

Answer Engine Optimization

Make your content the best answer. Think of it as preparing your content to be quoted by AI.

Fast results: days

GEO

Generative Engine Optimization

Become part of AI's memory. Build such strong brand authority that AI remembers you long-term.

Slow results: months

LLMO

LLM Optimization

Help AI understand who you are. Technical work to make sure AI correctly identifies and categorizes your brand.

Ongoing

Bottom line: they all mean the same thing. Make your brand visible when AI answers questions in your industry.

Take Action

For CEOs & CMOs

Your brand needs an AEO strategy just like it needs an SEO strategy. Ask your marketing team: "What happens when someone asks ChatGPT about our category?"

For Marketing & Tech Teams

Start by asking ChatGPT, Claude, and Perplexity about your product category. Screenshot the answers. Note which competitors appear and whether you're mentioned.

SEO vs AEO: what actually changed

With SEO, you were trying to get on page 1 of Google. With AEO, you're trying to get INSIDE the answer. The user never sees a list of links — they get a direct recommendation.

Before (SEO)

Sees 10 blue links

Now (AEO)

Key Insight

83% of AI citations come from pages NOT in Google's top 10. Being #1 on Google does NOT mean AI will mention you.

Take Action

For CEOs & CMOs

If your team only reports Google rankings, you're missing the picture. Request an AI visibility audit alongside your SEO reports.

For Marketing & Tech Teams

Add AI citation tracking to your monthly reporting. Tools like FAIMOUS, Otterly.AI or HubSpot AEO Grader are good starting points.

The research that proves it works

Researchers from Princeton and Georgia Tech tested 9 ways to make content more visible to AI. The 3 that worked best were embarrassingly simple:

+40%
Add sources & citations
visibility boost
+35%
Include expert quotes

+35%
Include statistics & data

Challenger Brand Advantage

If you're NOT the market leader, this is great news. The study showed that the 5th-ranked brand gained +115% visibility while the #1 brand actually LOST 30%. AEO levels the playing field.

Take Action

For CEOs & CMOs

This is a competitive equalizer. Smaller brands benefit MORE from AEO than category leaders. If you're a challenger brand, this should be a top priority.

For Marketing & Tech Teams

Audit your top 10 pages. Do they include cited statistics? Expert quotes? Source links? If not, that's your first optimization task.

Key Takeaways

  • AEO, GEO, and LLMO are three names for the same idea: make your brand visible in AI answers.
  • 83% of AI citations come from pages outside Google's top 10 — SEO rankings alone are no longer enough.
  • Challenger brands benefit most from AEO: +115% visibility for #5 vs -30% for #1.
  • The 3 most effective techniques are simple: cite sources, include expert quotes, and add statistics.
