Add a PerplexityBot group
Perplexity uses PerplexityBot to crawl the web for search. If your robots.txt blocks User-agent: * or names PerplexityBot under Disallow, Perplexity should not index those paths.
Put a specific group in robots.txt:
User-agent: PerplexityBot
Allow: /The most specific matching user-agent group applies. A dedicated PerplexityBot group overrides a blanket * disallow for that bot.
If you currently block all bots
A common accidental block looks like this:
User-agent: *
Disallow: /That hides the site from PerplexityBot and from Googlebot. Do not “fix AI” by opening * unless you mean to open every crawler. Prefer named groups for the bots you want.
User-agent: *
Disallow: /
User-agent: Googlebot
Allow: /
User-agent: PerplexityBot
Allow: /Confirm the change
Deploy robots.txt at the site root — https://example.com/robots.txt — then run a check. The report should show PerplexityBot as Allowed. If it still says Blocked, you likely have another Disallow in the same group, a CDN-cached file, or a different host (www vs apex).
Allowing PerplexityBot does not guarantee a citation. It only removes the access block. See the other search bots if you also want ChatGPT and Claude fetch access.
