GEO & AI Search
GEO vs AEO vs SEO: The Complete Guide to AI Search Optimization in 2025
Quick Answer
SEO optimizes for traditional search rankings (blue links on Google). AEO optimizes for featured snippets and Google's AI Overviews. GEO optimizes for citations in AI chatbots like ChatGPT, Perplexity, and Claude. They're not competing strategies—they're complementary layers of a complete search visibility approach.
Three acronyms. A lot of confusion.
If you've tried to understand the difference between SEO, AEO, and GEO, you've probably encountered conflicting definitions, overlapping concepts, and marketing jargon designed to sell you something.
Let's fix that.
By the end of this guide, you'll understand exactly what each optimization type does, when to use each, and how they work together.
The Simple Explanation (No Jargon)
Think of search like asking three different types of librarians for help:
SEO
Like optimizing your book's cover and title so it appears on the "recommended" shelf.
Goal: Rank in search results
AEO
Like writing your key insight on the book's back cover so the librarian can quote it directly.
Goal: Get featured as the answer
GEO
Like making sure the AI assistant has read your book and recommends it when asked.
Goal: Get cited by AI tools
SEO = be found. AEO = be quoted. GEO = be recommended.
What Each Actually Means
Foundation Layer
SEO: Search Engine Optimization
What it is: Optimizing your website to rank higher in traditional search engine results (the blue links on Google).
Been around since: Late 1990s
Core tactics:
- Keyword research and targeting
- On-page optimization (titles, meta descriptions, headers)
- Technical optimization (site speed, mobile-friendly, crawlability)
- Link building and authority development
- Content creation and optimization
Still relevant? Absolutely. SEO remains the foundation. 68% of online experiences begin with a search engine (BrightEdge), making SEO essential for discovery.
Answer Layer
AEO: Answer Engine Optimization
What it is: Optimizing content to appear in featured snippets, knowledge panels, and Google's AI Overviews.
Been around since: 2016 (when featured snippets became prominent)
Core tactics:
- Answer-first content structure
- Question-based headings (What, How, Why)
- Concise, extractable paragraphs
- Schema markup for rich results
- FAQ sections
Still relevant? More than ever. AI Overviews now appear in 47% of Google searches.
Citation Layer
GEO: Generative Engine Optimization
What it is: Optimizing content to be cited and recommended by AI chatbots like ChatGPT, Perplexity, Claude, and Gemini.
Been around since: 2023 (emerged after ChatGPT's mainstream adoption)
Core tactics:

Still emerging? Yes, but growing fast. AI referral traffic grew 527% year-over-year according to the 2025 Previsible AI Data Study.

| Success Metric | Rankings, organic traffic | Featured snippet capture rate | AI citation frequency |

Note: These aren't competing strategies. They're complementary layers of a complete search visibility approach.
See the Difference: Same Query, Three Experiences
Here's what happens when someone searches "best CRM for small business" across different platforms:
SEO: Traditional Results
AEO: Featured Answer
GEO: AI Citation
The takeaway: The same query produces three different experiences. Optimizing for just one means missing two-thirds of potential visibility.
How SEO, AEO, and GEO Work Together
Here's the key insight most guides miss:
GEO doesn't replace SEO. It builds on it.
The Search Visibility Stack
- 1
SEO Foundation
Get indexed, build authority, rank for keywords
- 2
AEO Layer
Optimize for featured snippets and AI Overviews
- 3
GEO Layer
Structure for AI citation and recommendation
- 4
Complete Visibility
Found in search, featured in answers, cited by AI
Think of it like this: SEO gets you in the library. AEO puts you on the display shelf. GEO makes sure the AI librarian recommends your book when someone asks for help.
The good news: many tactics overlap. Good content structure helps all three. Strong E-E-A-T signals benefit all three. Quality backlinks support all three.
The key difference is what you're optimizing for:
SEO
Optimize for ranking algorithms
AEO
Optimize for answer extraction
GEO
Optimize for AI citation
Which Should You Focus On First?
It depends on your audience and goals:
If you're starting from scratch...
Build SEO foundation first. You can't optimize for AI citation if you're not indexed and authoritative.
If you already rank well...
Add AEO and GEO layers. Optimize existing content for featured snippets and AI extraction.
If your audience uses AI tools for research...
Prioritize GEO alongside SEO. Your prospects might find you through ChatGPT before Google.
If you're in B2B or technical fields...
GEO is especially important. Decision-makers increasingly use AI for research and recommendations.
The safest approach for most businesses:
60% SEO foundation + 20% AEO optimization + 20% GEO tactics
Adjust based on where your audience actually discovers you.
Common Misconceptions (Cleared Up)
"GEO will replace SEO"
Reality: No. Gartner predicts 25% search decline by 2026, not elimination. Traditional search will remain the primary traffic source for years. GEO is an addition, not a replacement.
"AEO is just a subset of SEO"
Reality: Partially true. AEO tactics build on SEO, but the optimization target is different. You can rank #1 without appearing in featured snippets, and vice versa.
"GEO is just rebranded SEO"
Reality: No. While 60% of SEO skills transfer to GEO, the targets are fundamentally different. SEO optimizes for ranking algorithms; GEO optimizes for AI citation algorithms.
"I can ignore AI search if my rankings are good"
Reality: Risky. Traffic is declining even for sites with stable rankings. If AI answers your audience's questions, they won't click through regardless of where you rank.
