Question 1

What is AEO (AI Engine Optimization)?

Accepted Answer

AEO (AI Engine Optimization) is the practice of optimizing web content so it is easily understood, indexed, and cited by AI-powered search engines and agents like Perplexity, ChatGPT Search, and Google Gemini. Unlike traditional SEO, AEO focuses on structured data (JSON-LD schemas), clear Q&A formats, semantic HTML5 markup, and explicit authorship signals.

The AEO score is calculated across 6 weighted categories totaling 100 points: Structured Data & Schema (20pts) — JSON-LD, FAQPage, Speakable schemas; Content Clarity (20pts) — Q&A structure, factual language, word count; Technical Accessibility (15pts) — JS dependency, canonical URL, robots directives; Authority & Trust / E-E-A-T (20pts) — author info, publication dates, external citations; Semantic Structure (15pts) — HTML5 semantic tags, heading hierarchy, alt texts; Freshness & Completeness (10pts) — FAQ section, RSS feed, current year references.

Question 5

What is llms.txt and why does it matter?

Accepted Answer
