Perplexity behaves differently from Google and from ChatGPT in one specific way that changes how you should think about getting cited there: it leans on community and discussion sources, especially Reddit, far more heavily than either of the other two. Multiple independent studies of Perplexity's citation patterns put Reddit as the single most-cited domain across a wide range of query types, ahead of traditional publishers.
Why Reddit specifically
Perplexity's retrieval system appears to weight pages that show genuine back-and-forth discussion and recent activity. A Reddit thread where five people debate the merits of a product, with actual disagreement and detail, reads as more trustworthy to the retrieval system than a single brand's polished marketing page making the same claim. If your category has active discussion happening on Reddit, that discussion is already shaping what Perplexity tells people about you, whether you're participating or not.
What this means practically
- Monitor what's being said about your category on Reddit, not just your brand name specifically. If people are comparing you to competitors in a thread you don't know exists, that thread may already be shaping AI-generated answers about your space.
- Participate as a genuine contributor, not a marketer. Reddit's culture punishes obvious self-promotion quickly and visibly. Answering questions honestly, including ones where a competitor is the better fit, builds the kind of credibility that actually gets picked up.
- Don't try to fake this with sockpuppet accounts. Beyond being against Reddit's rules, it's detectable, and getting caught does more damage to your entity signals than staying off Reddit entirely would.
Reddit isn't the whole story
Perplexity does cite traditional websites too, and the same fundamentals that help with Google and ChatGPT still apply: clear, direct content; accurate and current information; pages that load fast enough to be retrieved without timing out. The Reddit weighting is a difference in degree, not a replacement for the basics.
Freshness matters more here than on Google
Perplexity's default behavior favors recent sources for most query types, even ones that aren't obviously time-sensitive. A page from three years ago competing against a page from three months ago on the same topic is at a real disadvantage, independent of which one is more accurate. Keeping content visibly updated, with a real dateModified and substantive changes behind it, carries more weight on Perplexity than it does in classic Google rankings.
What we tell clients
If your category has any meaningful discussion happening online, spend time understanding what that discussion says about you before spending time optimizing pages for Perplexity directly. The page-level fundamentals are necessary but not sufficient. The community conversation is the part most businesses haven't thought to look at yet.
