LLM Platform
Perplexity
Also known as: Perplexity AI, Perplexity Comet
An answer engine that combines retrieval with LLM synthesis and shows inline citations by default. Higher attribution rate than most platforms, citations are part of the product, not an afterthought.
What it is
An answer engine that combines retrieval with LLM synthesis and shows inline citations by default. Its attribution rate is higher than most platforms, making sources visible and clickable.
Why it matters
It matters because its citation-first design means visibility translates directly into named exposure and referral traffic, offering clearer measurement than platforms that synthesise without attribution.
How it works
You earn presence by ranking well in the sources it retrieves, publishing crisp, directly quotable answers, and maintaining content that cleanly matches the question being asked.
When it applies
Prioritise it when measurable referral traffic and explicit citation are goals, and for research-heavy or comparison queries where users want sources.
Examples
- Perplexity answers a how-to query and lists your article among the inline citations.
- A comparison search surfaces your brand with a footnoted source link users can click through.
- A follow-up question pulls an additional page from your domain into the cited set.
How it is measured
- Citation rate: how often your domain appears in the inline source list.
- Referral traffic and click-through from Perplexity citations.
- Average citation position within the source set.
- Share of category queries where your domain is cited at all.
