Traditional SEO audits focus on page load speeds, backlink profiles, and keyword optimization. While these metrics remain important, they represent only half of the modern SEO equation.

With the rise of ChatGPT, Google Gemini, and Perplexity, eCommerce stores must optimize for machine indexers. You need to ensure AI models can read and recommend your products.

To evaluate your store’s readiness for conversational search, you must perform an AI visibility audit. This checklist provides a step-by-step framework to review your catalog and policies.

Use these checklist items to protect your store’s search visibility and ensure your products show up in conversational search summaries in 2026.

The AI Visibility Checklist:

1. The llms.txt Configuration

The llms.txt file is the new standard for AI crawling. It provides LLM scrapers with a clean markdown roadmap of your website’s primary resources.

llms.txt Audit Items:
  • Create an llms.txt file in your website’s root directory (e.g., yourstore.com/llms.txt).
  • Verify the file contains a high-level summary of your brand and links to major product collections.
  • Include links to your shipping terms, return policies, and general compliance pages.
  • Define an llms-full.txt file for deep text caching of your primary landing pages.

To learn more about the structure and syntax of this file, read our comprehensive guide on LLMs.txt for eCommerce Stores.

2. Semantic Product Descriptions

AI search engines do not just match keywords; they evaluate intent. Your product descriptions must use natural language that matches conversational queries.

Product Page Audit Items:
  • Remove thin description blocks and replace them with detailed, benefit-driven copy.
  • Integrate natural-language answers to common customer questions about the product.
  • Use structured tables to display specifications (dimensions, materials, weight) to avoid parsing errors.
  • Verify Product, Offer, and Review schema are correctly configured and error-free.

Ensuring your descriptions are clear is also a requirement under WCAG digital accessibility guidelines. Visually impaired shoppers rely on screen readers to parse this information, which directly affects your store’s usability.

3. Category Content Structure

Category pages help AI crawlers understand the relationships between your products. An unstructured category layout makes it difficult for LLMs to build correct entity maps.

Category Audit Items:
  • Add short, descriptive introductory paragraphs to every category page.
  • Use clear, descriptive heading structures (H2 and H3 tags) to group sub-categories.
  • Avoid endless infinite-scroll layouts without a semantic pagination alternative.
  • Implement breadcrumbs with valid breadcrumb schema markup.

Additionally, if you run a PrestaShop or Magento store, you must ensure your category layouts support smooth navigation. Read our general EU eCommerce Compliance Hub to review user navigation compliance.

4. Clean XML/JSON Product Feeds

AI models like Google Gemini require access to real-time inventory and pricing data. They cross-reference web pages with structured product feeds to ensure accuracy.

Product Feed Audit Items:
  • Validate that XML or JSON feeds update automatically whenever product details change.
  • Verify your feed includes correct identifiers, including GTIN, brand, and SKU.
  • Align feed prices with storefront prices to prevent compliance discrepancies.
  • Ensure correct VAT or sales tax calculations are reflected in tax attributes.

Maintaining tax accuracy is critical for general compliance. In Europe, B2B merchants must automate verification processes, such as linking checkouts to automated VIES VAT validation. This ensures that zero-rated VAT invoices are only issued to verified entities.

5. Machine Crawler Controls

An AI visibility audit is not just about letting crawlers in; it is about managing permissions. You must decide which bots are allowed to scrape your store.

Crawler Control Audit Items:
  • Review your robots.txt file for blocked AI user-agents (such as GPTBot or ClaudeBot).
  • Ensure your server configuration does not block legitimate search scraper APIs.
  • Implement rate-limiting to prevent AI bots from slowing down your checkout.
  • Verify your store’s security headers protect user data without blocking compliant search indexing.

Warning: Completely blocking all AI crawlers protects your data copyright but destroys your conversational visibility. You must maintain a balanced opt-in strategy to keep your products discoverable on ChatGPT and Perplexity.

For merchants operating under strict tax mandates, secure crawler controls protect sensitive transactional APIs. Check our documentation on Factur-X invoicing integration to learn how to keep transactional endpoints secure.
