Free AI Site Audit

What Is an AI Site Audit?

An AI Site Audit is a structured technical assessment of your website across the five dimensions that determine whether AI systems like ChatGPT, Gemini, and Claude can find, read, understand, and cite your brand.

Unlike a traditional SEO audit — which focuses on Google rankings — an AI Site Audit focuses on machine readability: whether your site's architecture, schema markup, sitemap, and content structure give AI the signals it needs to include you in generated answers.

Most businesses discover that even well-ranked websites have critical gaps in their AI readability. These gaps are invisible to standard analytics tools and rarely show up in Google Search Console.

The Five Audit Dimensions

AI Crawlability & Indexability

Are the right AI crawlers (GPTBot, ClaudeBot, Google-Extended, PerplexityBot) allowed to access your pages? Does your robots.txt accidentally block them? Is your llms.txt correctly configured to guide AI retrieval bots? This module checks every crawl configuration signal that affects whether AI can reach your content at all.

Schema Health

Structured data (JSON-LD schema markup) is how AI systems understand the type, context, and credibility of your content. This module checks whether the five key schema types — Organization, Service, Product, Article, and FAQ — are correctly implemented on the right pages, and whether they follow the VERA Framework for AI-parseable structure.

Sitemap Health

AI crawlers use your sitemap to understand the scope and recency of your content. This module checks whether your sitemap exists, is correctly formatted, carries accurate lastmod dates, prioritises your most important pages, and avoids the most common errors that cause AI systems to deprioritise your content during indexing.

Brand Entity Clarity

AI systems build an internal model of what your brand is, what it does, who it serves, and where it sits in your category. This module assesses whether your website provides the consistent, unambiguous entity signals that allow AI to describe your brand accurately — including your name, description, category, differentiation, and location.

AI Content Optimisation

Beyond technical signals, the structure and language of your content affects whether AI includes it in generated answers. This module checks whether your content uses clear declarative statements, FAQ sections, structured definitions, and the kind of authoritative, source-ready language that AI systems cite rather than paraphrase.

What You Receive

• An overall AI Site Audit score (0–100) and status (Strong / Good / Needs Work)
• Individual scores for all five audit dimensions
• Specific findings within each dimension — not a generic checklist, but findings about your actual website
• A prioritised list of the highest-impact issues to fix first
• A benchmark showing how your scores compare to similar businesses in your category

Who Is This For?

The AI Site Audit is useful for any business that wants to understand and improve its AI discoverability. It's particularly valuable for:

• Businesses that rank well on Google but don't appear in AI-generated answers
• SaaS and software companies whose technical teams want a detailed crawl and schema review
• Marketing teams preparing a content or schema fix before commissioning a full AI Visibility Report
• Founders who want a fast baseline before investing in AI SEO implementation
• Agencies and consultants auditing client websites for AI readiness

The Data Behind It

Zaillor's audit methodology is based on crawl and schema analysis of over 500 small and medium business websites in 2026. Key findings from that research:

• 28.6% of websites had none of the three foundational AI crawlability files in place
• Only one in four websites had robots.txt, sitemap, and llms.txt all functioning correctly
• More than half of sitemaps carried no lastmod date information
• 87.6% of websites lacked all five schema types needed for reliable AI citation

How It Works

Enter your website URL and email address. Zaillor's audit engine crawls your site, checks each of the five dimensions against a set of structured rules, and returns your scored results. The full audit typically completes within 3–5 minutes.

No installation required. No access to your CMS or hosting account. The audit works from your public-facing website.

Frequently Asked Questions

Is the AI Site Audit free?

Yes. The audit is completely free with no credit card required. Zaillor offers it free because identifying your AI readiness gaps is the necessary first step before any fix.

How is this different from the AI Visibility Score?

The AI Visibility Score measures how AI systems currently describe your brand — it tests ChatGPT, Gemini, and Claude directly and scores the outputs. The AI Site Audit is a technical review of your website's structure and signals — it tells you why your score is what it is and what to fix. The two tools complement each other.

What if my score is low?

A low score is the starting point, not a permanent state. Each finding in the audit report comes with a description of the issue. Zaillor's AI SEO Implementation service can address all five dimensions as a managed engagement.

Do I need to be technical to understand the results?

No. Each finding is written in plain language with a clear explanation of what the issue means for your AI visibility. Technical findings are labelled clearly so you can share the relevant sections with a developer if needed.

How often should I run the audit?

After any significant website change — a new CMS, a site redesign, changes to robots.txt or sitemap, or new schema implementation. As a baseline, running the audit quarterly is a good practice for businesses actively working on AI visibility.
