## What is PerplexityBot?

Indexes pages for Perplexity search, not foundation-model training.

## How to identify it

Look for the PerplexityBot identifier in a request’s User-Agent. This is a name match, not identity verification. Version strings may change.

## How to check identity

Compare the request IP with the PerplexityBot IP list linked in Perplexity’s crawler documentation.

## Access and robots.txt

Use a PerplexityBot robots.txt group to control search crawling independently of Perplexity-User fetches.

Optional full-site opt-out; merge with existing rules only if intended. Not a security control.

```text
User-agent: PerplexityBot
Disallow: /
```

## What it means in your analytics

Indexing may make information available for answers. A bot hit alone is not a citation, referral or sale.

## Useful measures

Public-page coverage; Retrieval failures; Referrals separately.

## What to check next

Check the availability of the pages you want search systems to retrieve, then measure downstream referrals separately.
