Complete Guide

The Complete Guide to AI SEO Auditing

The rise of AI-powered search has fundamentally changed what it means to be "optimized" for search. While traditional SEO focused on ranking in Google's blue links, AI SEO—also known as Generative Engine Optimization (GEO)—focuses on being understood, recommended, and cited by AI assistants like ChatGPT, Claude, Perplexity, and Gemini.

An AI SEO audit examines your website through the lens of AI systems, identifying issues that prevent AI crawlers from accessing your content, factors that affect how AI understands your business, and optimization opportunities that can improve your visibility in AI-generated responses.

Why AI SEO Audits Matter

The shift toward AI-powered search is accelerating. Research shows that 70% of users now use AI assistants for product research at some point in their buying journey. When someone asks ChatGPT "what's the best project management tool for remote teams" or asks Perplexity "compare CRM options for startups," the AI's response directly influences their decision.

Unlike traditional search where you might rank on page two and still get some traffic, AI responses are winner-take-all. The AI either mentions your business or it doesn't. There's no equivalent of "ranking on page two"—you're either in the response or you're invisible.

An AI SEO audit identifies the specific factors preventing your business from appearing in these AI responses and provides a prioritized roadmap for improvement.

The Five Pillars of AI SEO

Our audit examines your website across five critical categories, each contributing to your overall AI visibility:

1. Technical Foundation

Before AI crawlers can understand your content, they need to access it. Technical factors we check include:

  • SSL/HTTPS: AI crawlers prefer secure sites. An insecure site may be deprioritized or skipped entirely.
  • Page speed: Slow-loading pages may timeout during crawling, resulting in incomplete indexing.
  • Mobile responsiveness: AI systems index mobile versions of sites, making mobile optimization essential.
  • Server reliability: Frequent downtime means missed crawling opportunities.

2. AI Crawlability

This category examines whether AI crawlers can access and process your content:

  • Robots.txt configuration: Are GPTBot, ClaudeBot, and PerplexityBot allowed? Many sites accidentally block these crawlers.
  • LLMs.txt presence: Do you have the emerging standard file that tells AI what your business does?
  • XML sitemap: AI crawlers use sitemaps to discover and prioritize content.
  • JavaScript rendering: Content that requires JavaScript execution may not be visible to all AI crawlers.

3. Content Structure

AI models need well-structured content to extract accurate information:

  • Heading hierarchy: Clear H1 > H2 > H3 structure helps AI understand topic organization.
  • Semantic HTML: Using proper article, section, nav, and aside elements aids AI comprehension.
  • Content organization: Logical flow with clear topic delineation.
  • Internal linking: Helps AI understand relationships between your content.

4. AI Optimization

Specific factors that help AI models understand and represent your business:

  • Structured data: Organization, Product, FAQ, Article, and other schema types.
  • Entity clarity: Clear identification of your business, products, and services.
  • FAQ content: Directly addressable question-answer pairs that AI can surface.
  • Author information: Clear attribution that establishes expertise.

5. Social and Sharing

How your content appears when shared and in previews:

  • Open Graph tags: Title, description, and image for social sharing.
  • Twitter Cards: Proper configuration for X/Twitter previews.
  • Rich previews: How your content appears in Slack, LinkedIn, and messaging apps.

Understanding Your Audit Score

Your AI SEO score is calculated based on the weighted importance of each check. Not all factors are equal—blocking AI crawlers entirely has more impact than having suboptimal Open Graph tags.

Score interpretation:

  • 80-100: Excellent. Your site is well-optimized for AI discovery. Focus on maintaining current practices and monitoring for new requirements.
  • 60-79: Good. You've addressed core requirements but have optimization opportunities. Focus on high-priority issues first.
  • 40-59: Fair. Common issues are affecting your AI visibility. Prioritize fixing critical issues like robots.txt and LLMs.txt.
  • Below 40: Needs work. Significant issues are preventing AI from properly understanding your site. Start with foundational fixes.

Most websites score between 30-50 because they haven't specifically optimized for AI search. This represents a significant opportunity—improving your score moves you ahead of competitors who haven't yet adapted.

Prioritizing Your Fixes

Not all audit findings require immediate attention. Here's how to prioritize:

Critical Priority (Fix Immediately)

  • AI crawlers blocked in robots.txt
  • No SSL certificate
  • Site returning errors
  • Critical content not rendering without JavaScript

High Priority (Fix This Week)

  • Missing LLMs.txt file
  • No structured data
  • Poor heading hierarchy
  • Missing or incorrect meta descriptions

Medium Priority (Fix This Month)

  • Missing FAQ schema
  • Incomplete Open Graph tags
  • No XML sitemap
  • Missing canonical tags

Lower Priority (Ongoing Improvement)

  • Page speed optimization
  • Additional schema types
  • Internal linking improvements
  • Content structure refinements

Common Audit Findings and How to Fix Them

AI Crawlers Blocked in Robots.txt

This is the most common critical issue. Many sites have legacy robots.txt files that use broad disallow rules or specifically block newer AI crawlers. The fix is straightforward: update your robots.txt to explicitly allow GPTBot, ClaudeBot, and PerplexityBot. Use our robots.txt generator to create an optimized file.

Missing LLMs.txt File

Without LLMs.txt, AI models must infer your business from scattered website content. Create a comprehensive LLMs.txt file that clearly describes your business, products, target audience, and use cases. Use our LLMs.txt generator to get started, then customize for your specific business.

No Structured Data

Structured data helps AI models understand entities and relationships on your site. At minimum, add Organization schema to your homepage and relevant schema (Product, Article, FAQ, LocalBusiness) to appropriate pages. Use Google's Structured Data Markup Helper or Schema.org documentation as references.

Poor Heading Hierarchy

AI models use heading structure to understand content organization. Ensure you have one H1 per page (your main topic), H2s for major sections, and H3s for subsections. Never skip levels (H1 to H3) and ensure headings accurately describe the content that follows.

Monitoring and Continuous Improvement

AI SEO isn't a one-time project—it's an ongoing practice. The AI search landscape evolves rapidly, with new crawlers, updated requirements, and emerging best practices.

We recommend:

  • Quarterly audits: Run a full audit every quarter to catch issues and track progress.
  • Post-launch audits: After any significant site update, verify you haven't broken AI accessibility.
  • Competitive monitoring: Periodically audit competitor sites to understand the competitive landscape.
  • Stay informed: Follow AI search news to learn about new requirements and opportunities.

Taking Action

Every day with unresolved AI SEO issues is a day when potential customers searching through AI assistants won't find you. The audit takes seconds to run and provides immediate, actionable insights.

Run your audit now, prioritize the findings, and start implementing fixes. Your competitors who haven't yet optimized for AI search are giving you an opportunity—the question is whether you'll take advantage of it.

Frequently Asked Questions

Why is AI SEO different from traditional SEO?

Traditional SEO optimizes for Google's blue links. AI SEO optimizes for how ChatGPT, Claude, Perplexity, and Gemini understand, recommend, and cite your content. AI models process your content differently—they extract meaning, not just keywords. They need clear structure, semantic HTML, proper AI crawler permissions, and files like LLMs.txt to accurately represent your business. As AI assistants become the primary way users search for information, traditional SEO alone is no longer enough.

What does this audit check?

We analyze 50+ factors across five categories: (1) Technical SEO—SSL certificates, page load speed, mobile responsiveness, AMP support, (2) AI Crawlability—robots.txt configuration, LLMs.txt presence, XML sitemap, AI crawler permissions, (3) Content Structure—heading hierarchy, semantic HTML, content organization, (4) AI Optimization—structured data, schema markup, entity recognition, FAQ schema, (5) Social & Sharing—Open Graph tags, Twitter Cards, rich preview optimization.

What is an LLMs.txt file and why do I need one?

LLMs.txt is a standardized file (like robots.txt) that tells AI models what your business does, who it's for, and when to recommend it. Place it at yoursite.com/llms.txt and AI crawlers will parse it directly. Without LLMs.txt, AI models must infer your business from scattered website content—often getting it wrong. LLMs.txt is becoming essential for AI visibility.

What's a good AI SEO score?

Most websites score between 30-50 because they haven't optimized for AI search yet. A score of 70+ puts you ahead of most competitors. Don't aim for 100—focus on fixing high-priority issues first. Typically, addressing robots.txt, adding LLMs.txt, and fixing structured data provides the biggest visibility improvements.

How does robots.txt affect AI visibility?

Your robots.txt file controls which AI crawlers can access your content. If you block GPTBot, ClaudeBot, or PerplexityBot, your content won't appear in those AI's responses. Many sites accidentally block AI crawlers with overly restrictive rules. Our audit checks your robots.txt configuration and identifies any AI crawlers you may be unintentionally blocking.

What is structured data and why does it matter for AI?

Structured data (schema markup) provides explicit information about your content in a format AI can easily parse. This includes Organization schema, Product schema, FAQ schema, Article schema, and more. AI models use structured data to understand entities, relationships, and facts about your business. Without it, AI must infer this information—often incorrectly.

How often should I run this audit?

Run an audit after making significant site changes, and quarterly as a baseline check. AI search is evolving rapidly—new crawler requirements, optimization techniques, and best practices emerge regularly. Tracking your score over time helps measure the impact of your improvements and ensures you're keeping up with changes.

What should I fix first?

Focus on high-priority issues flagged in the audit. Typically: (1) Fix robots.txt to allow AI crawlers, (2) Add an LLMs.txt file, (3) Ensure SSL is active, (4) Add structured data/schema markup, (5) Improve heading hierarchy and content structure. These foundational elements have the biggest impact on AI visibility.

Does fixing AI SEO issues affect my Google rankings?

Most AI SEO optimizations also benefit traditional SEO. Structured data, fast load times, mobile responsiveness, and clear content structure are ranking factors for Google too. You're not choosing between AI SEO and traditional SEO—you're building a foundation that works for both.
