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.
CheckAEO evaluates your page across six key categories. Each category contributes to a weighted overall score from 0 to 100:
Scoring is page-type aware: product, pricing, and contact pages aren't penalized for skipping article-only signals like FAQ schema, author bylines, or publish dates.
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.
| Factor | Traditional SEO | AEO |
|---|---|---|
| Goal | Rank in search results | Get cited by AI engines |
| Focus | Keywords, backlinks | Direct answers, schema markup |
| Content format | Long-form optimized | Structured Q&A, concise answers |
| Success metric | Click-through rate | AI citation rate |
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.
