PerplexityBot: what it is and how to allow or block it
If you block it, Perplexity can't read your site when someone asks about what you do, and it won't quote you. To show up in answers, let it in.
What it is
Perplexity. Indexes the web for Perplexity, which always links its sources. It doesn't train models.
Like most AI crawlers, it reads the HTML exactly as your server sends it: whatever your site paints with JavaScript may never reach it.
How it identifies itself
Mozilla/5.0 (compatible; PerplexityBot/1.0; +https://perplexity.ai/perplexitybot)
This is what it sends in the User-Agent header. In robots.txt you only use the short name: PerplexityBot.
The lines for your robots.txt
Allow it
User-agent: PerplexityBot Allow: /
Block it
User-agent: PerplexityBot Disallow: /
