Partnerize tracking domain
What is prf.hn?
prf.hn is an affiliate tracking domain operated by Partnerize (formerly Performance Horizon). It is not malware, adware, or phishing — it registers affiliate clicks and forwards visitors to the merchant. If you found it in a link, a redirect chain, or your analytics, someone (possibly you) published a Partnerize affiliate link.
prf.hn is Partnerize’s click domain, used by major airlines, hotel groups, and retail brands. Unusually, tracking rides in the URL path (camref: segments), not query parameters — so tools that only inspect query strings misread prf.hn links entirely.
How prf.hn links work
Typical Partnerize link
https://prf.hn/click/camref:1101abcDE/destination:https%3A%2F%2Fmerchant.com%2FproductPartnerize encodes tracking as path segments: /click/camref:XXXX/destination:URL. The camref identifies your partnership; the destination segment carries the target page. On click, Partnerize registers the event and redirects.
Because everything is path-encoded, naive link checkers that parse query parameters see "no tracking parameters" and either false-alarm or skip validation. A Partnerize-aware checker parses the path segments.
When prf.hn links break
The failure signals Afterlink's validator detects on Partnerize links:
- ▸"campaign not found"
- ▸"this campaign has ended"
- ▸"link is no longer valid"
- ▸Destination segment returning 404
Frequently asked questions
Is prf.hn safe / legitimate?
Yes. prf.hn is official Partnerize tracking infrastructure, not malware or phishing. It appears in links because Partnerize routes affiliate clicks through it to register attribution before forwarding visitors to the merchant.
Why is prf.hn in my browser bar or analytics?
You clicked (or your visitors clicked) a Partnerize affiliate link. The domain appears briefly mid-redirect while the click is registered, then forwards to the destination site.
Can prf.hn links break?
Yes — Partnerize links fail when campaign ends or partnership is removed or the destination page dies. The domain keeps resolving either way, which is why broken ones look alive.
