Website visits that arrive via a link from another website, as tracked and categorized separately from organic search, direct, paid, or social traffic sources.
Why it matters
Referral traffic often indicates real, earned interest — someone linking to a site because they found it genuinely worth referencing — and identifying which specific referring sites drive the most (or best-converting) traffic can highlight partnership or outreach opportunities worth pursuing further.
In a sentence
"A meaningful share of our referral traffic came from one industry newsletter that had linked to our guide, which made it an obvious candidate for a deeper content partnership."

- Antonyms: Direct traffic (visitors who arrive by typing a URL directly or through a bookmark, with no referring source).
- Often confused with: Backlink (Part One, Category 4) — a backlink is the link itself, existing whether or not anyone ever clicks it; referral traffic is the actual visits generated by people clicking that link).
