PerplexityBot indexes pages for Perplexity answers. Measure it as a searcher in logs and Hardal AI Visibility, not as an ads pixel.

**PerplexityBot** indexes your pages so Perplexity can cite them in answers. That is a **searcher**, in Hardal's trainer / searcher / fetcher split. It is closer to [OAI-SearchBot](https://usehardal.com/blog/how-to-measure-oai-searchbot-traffic) than to [GPTBot](https://usehardal.com/blog/how-to-measure-gptbot-traffic).

When a person asks Perplexity a question and the product retrieves your URL live, you may also see **Perplexity-User**. That is the fetcher. Merge the two into "Perplexity traffic" and you will miss a live query on `/pricing`.

There is no Perplexity Ads conversion destination in Hardal. Do not install the OpenAI Measurement Pixel for this bot.

## How it shows up

User-agent contains `PerplexityBot`. Playbook log snippets already include it next to GPTBot and ClaudeBot ([AI Visibility Playbook](https://usehardal.com/playbook/ai-visibility)). GA4 still will not record the crawl. Human click-throughs from Perplexity, if they happen, show up like any other referrer as long as the browser runs tags. The crawl that decided whether you were citable never ran a tag at all.

## What to report

- Which URLs PerplexityBot actually reads. Zero hits on the comparison page you care about means you are not in that index, no matter how good the copy is.
- PerplexityBot vs Perplexity-User. Fetch spikes are the "someone asked just now" line. Same play as ChatGPT-User in [AI crawler traffic for marketers](https://usehardal.com/blog/ai-crawler-traffic-for-marketers).
- robots.txt: allow the indexer if you want citations; blocking it is a visibility choice, not an SEO-Google choice.

## robots.txt

Stay eligible for citations:

```
User-agent: PerplexityBot
Allow: /
```

Block indexing (you will not show up as a cited source the same way):

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

User-initiated fetches are a different token. Perplexity has argued robots.txt may not bind those the way it binds the indexer. Measure them anyway.

## How Hardal measures it

[AI Visibility](https://usehardal.com/ai-visibility) identifies PerplexityBot by name and attributes it to Perplexity. [isvisible.ai](https://isvisible.ai) checks whether Perplexity's agents can access the site at all. First-party server-side, no extra script.
