## How to use the ai crawler checker

1. ### Paste an address

   A full URL or just a domain. We add https:// when it is missing.
2. ### We fetch it live

   Our server requests the page now, the way a crawler would, and records what came back.
3. ### Read the evidence

   Every result shows the value we read, so you can see why it passed or failed.
4. ### Fix and check again

   Change the page, run it once more, and ship when the second run agrees.

### What this does not measure

We would rather say what a tool cannot see than let a clean result mislead you.

- It fetches the page as each crawler from one location at one moment. A crawler blocked in another country, or tomorrow, is not visible here.
- A block is not always a defect. Blocking a training crawler in robots.txt is a valid opt-out and the tool labels it as one.
- It cannot see whether the crawler already has the page in an index from before the block was applied.
- Perplexity-User and ChatGPT-User fetch only when a person asks, so they may be allowed while the indexed crawlers are not.

Want the full picture?

This tool answers one question. A full audit runs every check on a page, scores it, and gives you a short list of what to fix first.

## Questions about the ai crawler checker

More in the [guides](https://crawlwise.site/guides).

### What does the AI crawler checker do?

See which AI crawlers can read your URL — ChatGPT, Claude, Perplexity and more. Find fixable blocks before you miss citations. Free, no sign-up.

### Do I need a Crawlwise account to use AI crawler checker?

No. Every tool in the free toolkit runs without sign-up, card, or email. A full site audit and saved history require an account and credits.

### What can AI crawler checker not tell me?

It fetches the page as each crawler from one location at one moment. A crawler blocked in another country, or tomorrow, is not visible here.

### How is this different from a paid SEO suite?

Crawlwise shows the evidence behind each result and prices work in credits. Suites bundle backlinks and ads research; we focus on measurable on-page health and crawler access.

### Can I run the same check on my whole site?

The free tool answers one URL or one question. Add a site in Crawlwise to crawl many pages, export reports, and track changes over time on paid plans.

### Will fixing what the tool flags improve rankings?

Nothing outside Google can promise rankings. Fixing real technical issues removes friction for crawlers and readers; it is necessary but not sufficient for visibility.
