Which schema types matter most for AEO?
Quick Answer
The highest-impact schema types for AEO are FAQPage (for Q&A content), Article/BlogPosting (for editorial content), Organization (for brand identity), HowTo (for instructional content), and BreadcrumbList (for site structure). FAQPage schema has the most direct impact because AI engines are fundamentally question-answering systems. Organization schema is foundational for entity recognition. Start with these five types and expand to more specific schemas like Product, LocalBusiness, or Person as needed.

Related Questions
What is schema markup and why is it important for AEO?
Schema markup is structured data code that you add to your web pages to explicitly tell search engines and AI platforms what your content is about. For AEO, schema is critical because it helps AI engines rapidly parse your content — understanding who wrote it, what questions it answers, and how your organization relates to the topic. Pages with comprehensive schema markup consistently earn higher citation rates than pages without it. The most impactful schema types for AEO are FAQPage, Article, Organization, and HowTo.
How do I configure robots.txt for AI crawlers?
To configure robots.txt for AI crawlers, add explicit Allow rules for GPTBot, PerplexityBot, ClaudeBot, and OAI-SearchBot in your robots.txt file. Check for any blanket Disallow rules that might inadvertently block these bots. Many websites block AI crawlers without realizing it through overly broad blocking rules. You can selectively allow AI access to public content while blocking admin pages and private sections. Always include a Sitemap directive pointing to your XML sitemap.
What is llms.txt and should I create one?
llms.txt is an emerging standard file that provides AI language models with structured information about your website, similar to how robots.txt communicates with crawlers. It typically includes a site description, key pages, content categories, and preferred citation format. While not universally supported yet, creating an llms.txt is a forward-looking AEO tactic that takes only 15-20 minutes. Early adopters report improved citation accuracy from platforms that support it.
What is JSON-LD and how do I implement it?
JSON-LD (JavaScript Object Notation for Linked Data) is the preferred format for adding schema markup to web pages. You implement it by adding a script tag with type application/ld+json containing your structured data in JSON format. Google and most AI platforms prefer JSON-LD because it is separate from your HTML and easy to maintain. You can place JSON-LD in the page head or body, and tools like schema generators can create the code for you.
How do I test if my schema markup is working correctly?
Use Google's Rich Results Test at search.google.com/test/rich-results to validate your schema markup and check for errors or warnings. The Schema Markup Validator at validator.schema.org provides more detailed validation against the full Schema.org vocabulary. Additionally, check Google Search Console's Enhancements section for ongoing monitoring of schema issues across your site. Test each page template to ensure schema renders correctly for all content.
