AEO Schema Optimizer
Optimize your structured data for AI search engines. Detect existing JSON-LD, Microdata, and RDFa markup, validate schemas, and discover opportunities to improve your AI Engine Optimization.
What is an AEO Schema Optimizer?
An AEO (AI Engine Optimization) Schema Optimizer analyzes your webpages for structured data and identifies opportunities to improve your visibility in AI-powered search engines.
It detects JSON-LD, Microdata, and RDFa markup, validates schemas against schema.org standards, and generates ready-to-use structured data for better AI discoverability in ChatGPT, Perplexity, Google AI Overview, and Claude.

How to Use This Tool
Enter Your URL
Paste the full URL of the page you want to analyze. The tool works with any publicly accessible webpage.
Review Results
See all detected schema markup, validation status, and any issues that need fixing for optimal AI visibility.
Implement Schema
Copy the generated JSON-LD code for missing schema types and add it to your page's HTML head section.
What to Do with Your Results
Valid Schema Found
Great! Your existing schema is correctly implemented. Consider expanding with additional schema types from the opportunities section.
Issues Detected
Click on the schema card to view specific issues. Common fixes include adding missing required properties or correcting data formats.
Opportunities
Expand each opportunity to get pre-built JSON-LD code. Copy and customize with your actual data, then add to your page's <head> section.
Schema Format Comparison
This tool detects all three major structured data formats. Here's how they compare:
| Format | Syntax | Pros | Cons | Recommendation |
|---|---|---|---|---|
| JSON-LD | JavaScript in <script> tag | Easy to implement, separate from HTML, Google recommended | Requires JavaScript knowledge | Best Choice |
| Microdata | HTML attributes (itemscope, itemprop) | Inline with content, widely supported | Clutters HTML, harder to maintain | Legacy Use |
| RDFa | HTML attributes (vocab, typeof, property) | Powerful, supports multiple vocabularies | Complex syntax, less common | Specialized |
Most Impactful Schema Types for AI Visibility
Different schema types have varying levels of impact on AI search visibility. Here are the most valuable ones to implement:
| Schema Type | Best For | AI Impact | Key Properties |
|---|---|---|---|
| FAQPage | Help pages, support articles | Very High | mainEntity, Question, Answer |
| HowTo | Tutorials, guides, instructions | Very High | step, name, text, image |
| Article | Blog posts, news, content pages | High | headline, author, datePublished |

Why Schema Markup Matters for AI Search
AI systems like ChatGPT, Perplexity, and Google AI Overview rely on structured data to understand and cite web content accurately. Without proper schema markup, your content may be:
- Misinterpreted by AI models leading to incorrect citations
- Overlooked in favor of competitors with better structured data
- Missing from AI-generated answers and overviews
Proper schema implementation helps AI systems extract accurate facts, understand entity relationships, and cite your content correctly.

Implementation Best Practices
Do's
- • Use JSON-LD format for new implementations
- • Include all required properties for each schema type
- • Keep schema data synchronized with visible content
- • Test your schema using Google's Rich Results Test
- • Add schema to every relevant page, not just the homepage
- • Use specific schema types (e.g., SoftwareApplication vs. Product)
Don'ts
- • Don't add schema for content not visible on the page
- • Don't use misleading or exaggerated data in schema
- • Don't duplicate the same schema across unrelated pages
- • Don't mix multiple schema formats on the same page
- • Don't forget to update schema when content changes
- • Don't ignore validation errors and warnings
