## AI Readability Scan — Can machines read your site?

AI systems read your website every day – crawlers from ChatGPT, Claude, Perplexity and Google. But do they understand what they see?

The scan tests your domain on 33 checks across six layers – from access and legibility to identity and evidence – and shows what the machines actually understand.

No signup. The result is instant.

## How the scan works

1. Enter your domain. The scan fetches the front page, robots.txt, sitemap and the machine-facing files – exactly as an AI crawler would.

1. 33 checks across six layers – from access and legibility to identity, clarity, documentation and signal. Every check is something blackbook.dk itself passes.

1. The result is instant: score, concrete gaps with points – and a language model's description of your site based on the text a crawler can actually see. No signup.

## What is AI readability?

AI readability is how easily machines can read and understand your website. When ChatGPT, Claude or Perplexity answers a question, the answer is built on what their crawlers could fetch and interpret – not on what the page looks like in a browser.

Classic SEO is about ranking in search results. AI readability is about being understood and cited in answers. A site can rank fine on Google and still be invisible to an AI crawler that does not run JavaScript and does not guess who is behind the site. If you want help with the gaps, [LLMO – AI readability as a service](https://www.blackbook.dk/en/services/llmo/) is the natural next step.

## What the scan checks

### Access

Can AI systems even reach your content? (HTTPS, robots.txt, AI crawlers allowed, XML sitemap, Server-rendered content, Redirect consistency, Honest 404)

### Legibility

Can machines read the content without guessing? (llms.txt, Markdown version, llms-full.txt, Markdown sitemap, One H1 per page, Semantic landmarks, Heading hierarchy)

### Identity

Do machines know who is behind the site? (JSON-LD identity, sameAs links, Canonical, Language declaration, Favicon + og:image, Logo in schema, og:site_name + og:locale)

### Clarity

Do titles and descriptions say what the page is about? (Title quality, Meta description, H1 content, Distinct title)

### Evidence

Is there structured depth behind the surface? (Schema depth, Internal linking, Freshness signals, Offer catalog in schema)

### Signal

Does the site share itself correctly across platforms? (Open Graph complete, Twitter card, Image alt texts, .well-known files)
