What Is AI Legibility?

Most stores we measured have a gap. In our August 2026 study of 245 Shopify storefronts, the median AI legibility score was 46 out of 100. Two thirds of the stores scored below 50. Your browser runs the page's scripts and shows you the finished design. A crawler often works from the raw HTML the server sends first, and for many AI crawlers that HTML is the whole page.

What does AI legibility look like on a real website?

Take a furniture store on Shopify. Its product pages load the dimensions, the materials and the stock status with a script after the page opens. A shopper sees all of it. A crawler that runs no scripts receives a title, a price and a photo. Ask an assistant for a walnut desk under 48 inches wide, and it cannot confirm that this desk fits.

A law firm on WordPress can lose legibility in a different place. A security plugin that blocks unfamiliar bots can also block AI crawlers. The firm's practice area pages then never reach an assistant at all.

What does AI legibility cover?

• Access means that your robots.txt file and any firewall let AI crawlers fetch the page.
• Rendering means that the important text is in the HTML the server sends, so a crawler that runs no scripts still receives it.
• Structured data means that the Product, Organization and other markup on the page is valid and matches what a visitor sees.
• Facts such as materials, sizes, prices and policies should be written as text or data fields, and not only inside images.
• The business should be described the same way on every page and profile, which the page on entity recognition explains.

How do I check my website's AI legibility?

1. Open yourdomain.com/robots.txt in a browser and look for any line that names GPTBot, OAI-SearchBot, ClaudeBot or PerplexityBot above a Disallow: / rule.
2. In Chrome, type view-source: in front of the address of one product page and press Enter. Search that raw HTML for the product description and the price, since a crawler that runs no scripts sees only what is there.
3. Run the same page through Google's Rich Results Test and compare the price and availability in the Product data with what the page shows.
4. If the site sits behind a firewall or a bot protection service, check whether that service challenges AI crawlers. The Academy guide on Cloudflare and AI crawlers shows where one common setting lives.
5. Run a scan to measure all of these together on your live pages and get the fixes in order.

Common questions

How long does an AI legibility check take?

Your browser hides most of what matters, so you check each part directly. The steps on this page take about twenty minutes for one page, and the 20 minute AI visibility audit walks through a fuller version. A scan measures all of it on your live pages at once.

Is AI legibility the same as accessibility?

They overlap, but they are not the same thing. Accessibility is about people who use assistive technology, and AI legibility is about machines that read and quote your pages. Clear headings, real text and descriptive alt text help both.

Does a high AI legibility score mean AI will recommend my business?

A high score means AI systems can read and understand what is on your pages. What an assistant then says depends on the question and on other sources. The score measures what you can change, and it is not a promise of placement.
