Frequently Asked Questions

Should I Block PerplexityBot?

No, for the same reason you would not block Googlebot. PerplexityBot indexes your site for an AI search engine, and its results link back to you. Blocking it removes you from a whole search channel without helping your traditional rankings. For comparison, 16% of the top websites we track already have robots.txt rules for PerplexityBot.

Does PerplexityBot Respect Robots.txt?

Yes. PerplexityBot is expected to honor robots.txt rules, so a disallow rule is the right first move. Automatic Robots.txt adds and maintains that rule for you, and Agent Analytics confirms PerplexityBot actually honors it.

Does PerplexityBot Access Private Content?

No. PerplexityBot indexes what an anonymous visitor can load, like a traditional search crawler. The bigger risk is content that is public by accident, like a staging site, which it will happily index.

Why Is PerplexityBot Visiting My Website?

PerplexityBot is indexing your site so your pages can appear in its AI search results. It found you through links, your sitemap, or mentions of your domain, and it returns on its own schedule to keep the index fresh.

How Can I Tell if PerplexityBot Is Visiting My Website?

Agent Analytics tracks PerplexityBot visits and every other known AI agent, crawler, and scraper alongside it, then authenticates each visit against PerplexityBot's published verification method. You can also check your server logs for requests whose user agent string contains "PerplexityBot". Look for recurring visits spread across your site, like a search engine crawl. A log match is still not proof, because any bot can claim to be PerplexityBot.
