AI SEARCH & BOTS
AI Content Readability Checker
Most AI crawlers fetch a page once and read the HTML without running JavaScript. A page they are blocked from, or whose text only appears after scripts run, cannot be quoted. This check fetches a page the way they do and reports what stands in the way.

HOW IT WORKS
How to use the AI Content Readability Checker
One public page URL.
Enter the page’s URL.
Fix access and content-in-HTML problems first.
Then improve structure, structured data and dates.
WHAT IT CHECKS
What it looks at, and how to read it.
Checks on AI crawler access and how readable the page is without running JavaScript.
What it checks
- robots.txt rules for GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot, Claude-SearchBot, PerplexityBot and Google-Extended
- noindex
- Text in the HTML versus an app shell
- H2 sections and question headings
- JSON-LD and modified dates
- llms.txt
How to read the results
- Blocked AI search crawlers keep the page out of that product’s answers; that may be what you want.
- An app shell is the most common reason AI crawlers see an empty page.

GOOD TO KNOW
Common mistakes, an example and the limits.
Common mistakes
- Rendering product details only with JavaScript.
- Blocking every AI crawler with one copied rule set.
- Treating llms.txt as required; it is an unadopted proposal.
A worked example
A React store’s product pages show 40 words to crawlers because prices and descriptions load after JavaScript; server-rendering them fixes access for every crawler at once.
Limitations
- Checks access and readability; whether an AI product cites a page depends on much more, and no tool can promise it.
- Reads the HTML the server sends, as most AI crawlers do; content added by JavaScript is not seen.
FAQ
Questions about the AI Content Readability Checker
Straight answers about what it does and where its limits are.
Do AI crawlers run JavaScript?
Most fetch the HTML and do not run scripts. Google’s crawlers render pages, but AI search crawlers from other companies generally do not.
Will fixing these get my page cited?
It removes obstacles. Being cited still depends on the content being the best answer.
