6 Key AEO Factors That Determine AI Search Visibility

Our AEO checker examines the critical factors that determine how well AI search engines can understand and cite your content. Each factor is weighted by its impact on AI search visibility.

Quick Answer Blocks
AI search engines extract 40-60 word definition blocks from your pages. We check if your content has the right format to be cited as a featured answer.
LLMs.txt File
The llms.txt standard lets you provide AI-readable instructions for ChatGPT, Claude, and other LLMs telling them how to use and cite your content.
FAQ Schema (JSON-LD)
FAQPage structured data drives 3.1x higher answer extraction rates. We verify your FAQ schema is correctly implemented and contains enough questions.
Semantic HTML Structure
Proper use of article, header, section, and heading tags helps AI understand your content hierarchy. We check for correct H1 usage and logical structure.
HowTo Schema
Step-by-step structured data helps AI engines surface your tutorials and guides. We detect instructional content and verify HowTo markup is present.
AI Bot Access (robots.txt)
GPTBot, ClaudeBot, PerplexityBot, and Google-Extended need permission to crawl your site. We check your robots.txt for all 10 major AI crawlers.

FAQ

Frequently Asked Questions About AEO

Everything you need to know about Answer Engine Optimization and how to get your website cited by AI search engines.

What is Answer Engine Optimization (AEO)?

Answer Engine Optimization (AEO) is the practice of structuring your website content so that AI-powered search engines — like ChatGPT, Perplexity, Claude, and Google AI Overviews — can easily extract, understand, and cite your pages in their responses. AEO goes beyond traditional SEO by focusing on structured data, semantic HTML, and AI-readable formats like llms.txt.

How is AEO different from SEO?

Traditional SEO optimizes for search engine result pages (SERPs) with links. AEO optimizes for AI-generated answers where your content is directly cited or quoted. While SEO focuses on keywords and backlinks, AEO focuses on structured data (FAQ schema, HowTo schema), semantic HTML, quick answer blocks, and AI crawler access. You need both SEO and AEO in 2026.

What is an AEO score?

An AEO score is a 0-100 rating that measures how well your website is optimized for AI search engines. It evaluates 6 key factors: Quick Answer Blocks (20%), FAQ Schema (20%), Semantic HTML (20%), llms.txt (15%), AI Bot Access (15%), and HowTo Schema (10%). A higher score means AI engines are more likely to cite your content.

How do I improve my AEO score?

Start by running a free AEO scan to see which of the 6 factors need improvement. Common fixes include: adding a 40-60 word definition block near the top of your pages, implementing FAQPage JSON-LD schema with at least 3 questions, creating an llms.txt file, using proper semantic HTML tags, and allowing AI bots in your robots.txt.

Which AI search engines does AEO Optimizer check for?

AEO Optimizer checks compatibility with all major AI search engines: ChatGPT (GPTBot), Perplexity (PerplexityBot), Claude (ClaudeBot), Google AI Overviews (Google-Extended), Amazon Alexa (Amazonbot), Cohere, Diffbot, and ByteDance (Bytespider). We verify your robots.txt allows each of these 10 AI crawlers to access your content.

Is the AEO scan free?

Yes, you can run a free AEO scan that shows your overall score and pass/fail status for all 6 factors. Paid plans (starting at $9.99/month) unlock detailed analysis with fix-it guides, copy-paste code snippets, platform-specific instructions, and scan history tracking.

What is llms.txt and why does it matter?

llms.txt is a plain-text file placed at your website root (yoursite.com/llms.txt) that provides AI-readable instructions about your site. It tells LLMs like ChatGPT and Claude what your site is about, which pages are most important, and how to cite your content. While not yet an official standard, early adoption signals AI-readiness to crawlers.

How often should I run an AEO scan?

We recommend running an AEO scan at least once a month, or whenever you make significant content or structural changes to your website. AI search algorithms evolve quickly, and regular scans help you catch new optimization opportunities and ensure your structured data remains valid.
