What is AI SEO? Complete Guide to AI Search Optimization
Everything you need to know about optimizing your business for ChatGPT, Perplexity, Claude, and other AI search platforms.
TL;DR - What is AI SEO?
AI SEO is the practice of optimizing your online presence to appear in AI-generated search results from ChatGPT, Perplexity, Claude, Gemini, and Google AI Overviews. Unlike traditional SEO that focuses on Google rankings, AI SEO focuses on being mentioned and cited when AI answers questions. Key elements include: technical setup (llms.txt, schema markup), content optimization for AI extraction, and building brand mentions across the web.
What is AI SEO? (Definition)
AI SEO (Artificial Intelligence Search Engine Optimization) is the practice of optimizing your online presence to appear in AI-generated search results and recommendations.
When someone asks ChatGPT “What's the best dentist in Sydney?” or asks Perplexity “Who should I hire for wedding photography in London?” - AI SEO determines whether your business gets mentioned in that answer.
You may also hear AI SEO referred to by other names:
- GEO - Generative Engine Optimization
- AEO - Answer Engine Optimization
- LLMO - Large Language Model Optimization
All these terms describe the same thing: optimizing your content and online presence so AI systems recommend your business when users ask relevant questions.

The Critical Difference
Traditional search shows 10 results. AI gives one answer. If your business isn't that answer, you've lost the customer before they ever visited a website.
The businesses that establish AI visibility now will dominate their markets for years to come. Those that wait will find it increasingly difficult to catch up as AI becomes the primary way people discover businesses.
AI SEO vs Traditional SEO
While AI SEO and traditional SEO share some principles, they have fundamental differences in goals, signals, and tactics.
| Aspect | Traditional SEO | AI SEO |
|---|---|---|
| Goal | Rank in Google search results | Get cited/recommended by AI |
| Key Signal | Backlinks | Brand mentions |
| Technical Files | robots.txt, sitemap.xml | llms.txt, robots.txt, schema markup |
| Content Format | Keyword-optimized pages | Extractable, citable content |
| Search Engine | Google primarily | Bing (critical), plus Google |
| Time to Results | 6-12 months | 30-90 days |
| Competition Level | Extremely high | Low (early adopter advantage) |
What Doesn't Work for AI SEO
- • Keyword stuffing
- • Building thousands of low-quality backlinks
- • Thin content optimized only for keywords
- • Ignoring Bing (ChatGPT uses Bing)
- • Generic, non-authoritative content
What Works for AI SEO
- • Clear, authoritative content
- • Brand mentions on trusted platforms
- • Structured data (schema markup)
- • llms.txt file for AI crawlers
- • Content that directly answers questions
The Three Pillars of AI SEO
Effective AI SEO is built on three foundational pillars. Missing any one of these will limit your visibility in AI-generated results.
Technical Setup
The foundation that allows AI to discover, crawl, and understand your content.
- llms.txt - Tell AI what content matters most
- robots.txt - Allow AI crawlers access
- Schema markup - Structured data for AI understanding
- Bing indexing - Critical for ChatGPT visibility
Content Optimization
Creating content that AI can easily extract, understand, and cite.
- Front-load answers - Put the answer in the first sentence
- Use extractable formats - Tables, lists, Q&A
- Semantic HTML - Proper headings and structure
- Regular updates - Keep content fresh with dates
Authority Building
Building the brand signals that make AI trust and recommend your business.
- Brand mentions - Get mentioned on platforms AI trusts
- Reviews & testimonials - Social proof AI can verify
- Industry citations - Be referenced by authoritative sources
- Consistent NAP - Name, Address, Phone across the web
How AI Search Engines Work
Different AI platforms work in different ways, which means your AI SEO strategy needs to account for each major player.
ChatGPT (OpenAI)
ChatGPT uses Bing for real-time web search. This means being indexed in Bing is critical for ChatGPT visibility. ChatGPT also draws from its training data (pre-2024) for general knowledge.
Key action: Submit your site to Bing Webmaster Tools and ensure Bing can crawl your content.
Perplexity
Perplexity has its own web crawler and indexes content directly. It's known for citing sources, so having authoritative, well-structured content increases your chances of being cited.
Key action: Ensure your robots.txt allows PerplexityBot and create content with clear, citable statements.
Google AI Overviews
Google's AI Overviews appear at the top of search results and synthesize information from multiple sources. Traditional SEO signals still matter here, but content structure for AI extraction is increasingly important.
Key action: Optimize for featured snippets and use FAQ schema markup.
Claude (Anthropic)
Claude primarily relies on its training data and has limited real-time web access. However, Anthropic is a pioneer of the llms.txt standard, meaning future versions will likely use this file for content discovery.
Key action: Create an llms.txt file and allow ClaudeBot in your robots.txt.

What is llms.txt?
llms.txt is a markdown file placed at your website's root directory (yoursite.com/llms.txt) that tells AI crawlers which content is most important. It acts as a curated reading list for AI systems, helping them understand your site's structure and prioritize your best content.
