Check Your AEO Score - Free Answer Engine Optimization Analyzer
CheckAEO is a free AEO (Answer Engine Optimization) tool that analyzes how well your website is optimized for AI answer engines like ChatGPT, Perplexity, and Google AI Overviews. Enter any URL and get an instant score out of 100 with prioritized, actionable recommendations.
Answer Engine Optimization (AEO) is the practice of optimizing web content so AI-powered answer engines can easily find, understand, and cite it. Unlike traditional SEO which focuses on ranking in search results, AEO focuses on making your content the answer that AI systems provide to users. Read our complete guide to AEO for a deeper dive. As more people use AI assistants like ChatGPT, Perplexity, and Google AI Overviews to find information, AEO is becoming essential for online visibility.
What does CheckAEO analyze?
CheckAEO evaluates your page across six key categories. Each category contributes to a weighted overall score from 0 to 100:
Direct Answer Quality (25%) — Does your content open with a clear, concise answer? Are sentences easy to parse? Is there a summary or key takeaways section? This is the highest-weighted category because AI engines prioritize content that directly answers questions.
Content Structure (20%) — Heading hierarchy, question-format headings, bullet lists, numbered lists, tables, and Q&A patterns. Well-structured content is easier for AI systems to parse and extract information from.
Schema Markup (20%) — FAQPage, Article, HowTo, BreadcrumbList, and speakable structured data in JSON-LD format. Schema markup helps AI engines understand the type and structure of your content.
Technical SEO for AI (15%) — Meta descriptions, canonical URLs, robots directives, language attributes, and Open Graph tags. These technical signals help AI crawlers access and understand your pages.
Entity & Topic Coverage (10%) — Internal linking, external references to authoritative sources, vocabulary richness, and author attribution for E-E-A-T (Experience, Expertise, Authoritativeness, Trust).
Freshness Signals (10%) — dateModified, datePublished in schema markup, visible dates on the page, and references to recent years.
How is AEO different from SEO?
Traditional SEO optimizes for search engine rankings and clicks. AEO optimizes for AI citations and direct answers. Read our AEO vs SEO comparison for the full breakdown. While SEO focuses on keywords, backlinks, and SERP positioning, AEO focuses on content structure, schema markup, and direct answer quality. Both are important — think of AEO as an extension of SEO for the AI era.

Why does AEO matter in 2026?
AI answer engines are changing how people discover information online. When someone asks ChatGPT or Perplexity a question, these systems pull answers from web content. If your content is well-structured with proper schema markup and clear answers, it's more likely to be cited. AEO-optimized content gets referenced, linked to, and drives qualified traffic from AI platforms. According to industry trends, AI-assisted search is expected to account for a growing share of web traffic, making AEO a critical investment for content creators and businesses.
