Always-on monitoring of Perplexity's two-bot fleet. PerplexityBot respects robots.txt and indexes; Perplexity-User is user-initiated and ignores robots.txt per Perplexity's own docs. Cloudflare flagged undeclared stealth crawling in August 2025. Sentry catches all three vectors. Cortex handles the fix.
Continuous audits of Perplexity's two declared bots and the stealth-fetch vector Cloudflare documented in 2025. Perplexity cites sources more explicitly than any other AI engine - inclusion here is a direct GEO win. Sentry catches the configuration gaps that exclude you. Cortex fixes it.
User-agent: PerplexityBot is not Disallowed. Per Perplexity's docs: PerplexityBot is the indexing crawler ('designed to surface and link websites in search results'), and the only Perplexity bot that respects robots.txt.
Recent PerplexityBot visitor IPs match perplexity.com/perplexitybot.json (the .com domain, not .ai). Filters spoofed UAs from non-Perplexity ASNs.
Recent Perplexity-User visitor IPs match perplexity.com/perplexity-user.json. Separate range from the indexing bot. Perplexity-User 'generally ignores robots.txt' per Perplexity's own docs — IP verification is the only enforcement vector.
Cloudflare's 'Block AI Scrapers' managed rule has PerplexityBot in its allowlist. Default-on on most Cloudflare plans, and blocks Perplexity at the edge regardless of robots.txt allowance.
Server logs show no Chrome-on-macOS fingerprint requests from Perplexity ASNs that lack the published UA. Cloudflare publicly disclosed this pattern in August 2025 and delisted Perplexity from its verified bot list.
Page-level JSON-LD parses cleanly. Perplexity reads structured data to compose answer snippets and source cards — high-signal for citation quality.
Server logs show a PerplexityBot fetch within the last 30 days, confirming the page remains in Perplexity's index. Recency correlates with citation eligibility.
Publishers wanting true exclusion from Perplexity must block via WAF + IP ranges, not robots.txt alone. Per Perplexity's docs: Perplexity-User 'generally ignores robots.txt' for user-initiated requests.
Paste your homepage URL. Sentry verifies robots.txt for PerplexityBot, dual IP-range fidelity, Cloudflare AI Audit posture, and presence of any undeclared stealth fetches, then ships a per-rule report. No signup, instant results, always free.
Sentry fetches your site, runs every PERPLEXITYBOT rule, and renders the full result page before your next sip of coffee.
Each failed rule ships with a prescription paragraph. Hand it to engineering and the gap is closed before lunch.
Add your site to the daily Sentry sweep with one click. New regressions get caught the next morning.
8 rules in the PERPLEXITYBOT Sentry. Daily 3:30 AM ET sweep.
One brain. Thirty-six pairs of eyes. Sentries monitor every visibility signal that decides whether search engines, AI engines, and ad platforms show you. Cortex reads what they see, weighs it against a unified corpus of platform documentation, and acts. Every move follows a defined decision protocol: action stated, reason given, impact named.
