Block or allow PerplexityBot in robots.txt
Put these lines at the top of the robots.txt file in your site’s root (example.com/robots.txt). Each subdomain needs its own file.
User-agent: PerplexityBot
Disallow: /
User-agent: PerplexityBot
Allow: /
# repeat here the Disallow lines of your User-agent: * group
If PerplexityBot is not named in robots.txt, it already follows your User-agent: * rules, so you don’t need anything. A group of its own replaces the * group for this bot entirely: if you add one, repeat your general Disallow lines in it.

“Webmasters can use the following robots.txt tags to manage how their sites and content interact with Perplexity.” — Perplexity documentation

Should you block PerplexityBot?
Think twice. PerplexityBot is how Perplexity’s AI search finds your pages; block it and your site can drop out of its answers and links. If your concern is model training, block the training bot instead.
