AI SEO Audit: Check Your AI Search Visibility 2026

An AI SEO audit checks your visibility across six AI platforms: ChatGPT, Gemini, Perplexity, AI Overviews, Claude, and Copilot. It tests your site structure, schema markup, crawlability, brand mentions, and content clarity to identify exactly why AI systems are or are not recommending your business.

What an AI SEO audit covers

Traditional SEO audits focus on Google rankings. An AI SEO audit goes further, testing whether AI platforms can understand, trust, and cite your business. The audit checks your presence across all six major AI search platforms, each of which pulls data differently.

ChatGPT indexes from Bing. Gemini draws from Google's index. Perplexity crawls the web independently. AI Overviews sit inside Google Search. Claude and Copilot each have their own retrieval methods. A proper audit tests all six.

What gets tested

• H1 clarity - whether your headings clearly state what the business does, so AI can categorise you
• Schema markup - whether you have Organisation, Person, and other entity schema (note: Google has deprecated FAQPage, so we check for body Q&A content instead)
• Robots.txt - whether you are blocking AI crawlers like GPTBot and ClaudeBot without knowing it
• Entity consistency - whether your business name, description, and services match across platforms
• Brand mentions - the strongest correlated factor for AI citations (0.664 in Ahrefs' 75,000-brand study, vs 0.218 for backlinks)
• Content structure - whether your content is formatted for AI extraction
• Freshness - whether key pages are updated often enough, since AI tends to favour recent content

What you get

A completed audit gives you three things: a visibility score showing where you stand, a gap analysis showing what is missing, and a prioritised action plan showing what to fix first. The best audits rank actions by impact so you know where to spend your budget.

How much does an AI SEO audit cost?

Prices range from free (basic checks) to over £2,000 for enterprise-level audits. Most mid-market audits sit between £500 and £1,500. Some agencies offer a free initial audit as a starting point. See our full AI search optimisation cost guide for detailed pricing.
