Answer Engine Optimization (AEO) is the practice of structuring website content so AI-powered search engines and assistants — such as ChatGPT, Google AI Overviews, Gemini, Claude, and Perplexity — can easily understand, summarize, and cite it as a direct answer to user questions. Unlike traditional SEO, AEO prioritizes semantic HTML, structured data, entity-rich writing, and answer-first formatting.

Answer Engine Optimization (AEO) helps your website become easier for AI assistants such as ChatGPT, Google AI Overviews, Gemini, Claude, and Perplexity to understand, summarize, and reference. Use our AI Visibility Analyzer to check how well your site performs, then follow this checklist to close any gaps. The following checklist covers the most important elements every modern website should include.

1. Answer the Main Question Immediately

The first paragraph should directly answer the page's primary question before providing additional details.

Example:

What is AEO?

Answer Engine Optimization (AEO) is the practice of optimizing content so AI systems can understand and deliver your information in generated answers.

2. Use a Proper Heading Structure

  • One H1 per page
  • Logical H2 sections
  • H3 for subsections
  • Never skip heading levels

3. Add a Frequently Asked Questions Section

Include questions that users actually search for and provide concise answers.

  • What is AEO?
  • How does AEO work?
  • Is AEO different from SEO?
  • Why is AEO important?

4. Implement Structured Data

Use Schema.org markup whenever appropriate.

  • Organization
  • Article
  • FAQPage
  • HowTo
  • BreadcrumbList
  • Product
  • SoftwareApplication

5. Use Tables

Traditional SEO AEO
Focuses on rankings Focuses on answers
Keywords Questions
Backlinks Understanding and context
Clicks Citations and AI visibility

6. Use Lists

AI systems frequently summarize content from bullet lists.

  • Schema markup
  • Entity optimization
  • Internal linking
  • Question-based headings
  • Clear definitions

7. Mention Recognizable Entities

Reference well-known platforms naturally throughout your content.

  • ChatGPT
  • Google AI Overviews
  • Gemini
  • Claude
  • Perplexity

9. Essential Metadata

Add a descriptive title and meta description that clearly communicates your page topic — the AI Visibility Analyzer shows how these tags appear to AI systems.

  • Title tag
  • Meta description
  • Canonical URL
  • Open Graph tags
  • Twitter Cards

10. Fast Loading

Aim for:

  • Fast Largest Contentful Paint (LCP)
  • Low Cumulative Layout Shift (CLS)
  • Low Interaction to Next Paint (INP)

Avoid unnecessary JavaScript when possible.

11. Clean URLs

Good:

  • /aeo-guide
  • /schema-generator
  • /faq-schema

Avoid:

  • ?id=18&page=5

13. Images

Every image should have descriptive alt text.

<img
  src="faq-schema-example.webp"
  alt="Example of FAQPage JSON-LD schema">

14. E-E-A-T Signals

Show who created the content and why it's trustworthy.

Include:

  • Author
  • Last updated
  • Sources (when appropriate)
  • Contact information
  • About page
  • Privacy policy

15. Semantic HTML

Prefer elements like:

  • <header>
  • <nav>
  • <main>
  • <article>
  • <section>
  • <aside>
  • <footer>

Avoid using only generic <div> elements.

16. Consistent Terminology

Use one term consistently.

For example:

✅ Always use "Answer Engine Optimization"

Avoid switching between:

  • AI SEO
  • LLM SEO
  • Generative SEO
  • AEO
  • GEO

without explaining that they're related.

17. Mobile-Friendly Design

  • Responsive layout
  • Readable font size
  • Large tap targets
  • No horizontal scrolling

18. XML Sitemap

Include every important page and keep it updated.

19. Robots.txt

Don't accidentally block important content.

20. Natural Language

Write as people ask questions.

Instead of:

Write:
