The 50 sources Perplexity cites most in B2B SaaS.
We ran 4,800 B2B SaaS buyer prompts through Perplexity (Sonar Pro and Sonar Reasoning) and counted every citation. Here's where the model goes first — and what it tells us about content strategy.
The headline
G2, Reddit and the official vendor docs together account for 41% of all citations. That's a remarkably concentrated graph: be in those three places, with current content, and you're in roughly 4 of every 10 answers.
The long tail that matters
Surprising sources that punched above their weight: PeerSpot, TrustRadius long-form reviews, Reddit r/sysadmin, Hacker News comment threads, and well-maintained changelogs on the vendor's own site.
What gets ignored
Gartner Peer Insights — paywalled. Press releases — almost never cited. Marketing landing pages without an obvious last-updated date — cited 76% less often than pages with one.
Action list
- Refresh your G2 page quarterly and answer every category question.
- Get one staff engineer to participate honestly in a relevant subreddit.
- Publish a public changelog with dates the model can read.
