An assistant can read this page, but some of it is guesswork.

  • Readable text without running JavaScript

    573 words arrive in the HTML itself.

  • Images describe themselves

    0 of 3 images have alt text.

  • Exactly one H1

    No H1 on the page.

  • Structured data (JSON-LD)

    None on this page.

  • …and 15 more, each with the fix written out.

Four questions, in order

A page has to survive all four to get quoted. Most sites fail at the second one and never find out.

  1. 1

    Can the bot reach you?

    Your robots.txt, your bot wall and your redirects decide this before a single word is read. A Cloudflare challenge page is the most common silent block.

  2. 2

    Can the bot read you?

    Most AI crawlers do not run JavaScript. If your text appears only after a script runs, they see an empty shell — we show you the exact text they got.

  3. 3

    Can the bot understand you?

    Title, description, one clear H1, headed sections, a canonical address. This is what turns a wall of text into something quotable.

  4. 4

    Can the bot cite you?

    Structured data and an llms.txt tell an assistant who you are, where you are and what you sell, in a form it does not have to guess at.

What we will not tell you

Nobody can promise you a mention in ChatGPT, and anyone selling you that is guessing. Crawlglass only reports things it can observe: what your server returned, what your robots.txt permits, and what text survives without a browser. Everything it suggests is a fix for something it actually saw.
