CJ Affiliate parameter
What is the cjevent parameter?
cjevent is CJ Affiliate's cj click id. cjevent is appended to the merchant URL by CJ Affiliate at click time and consumed by the merchant’s CJ tag for attribution. It replaced older CJ tracking mechanics as the primary click identifier.
Where it appears
Appended to the merchant URL after the redirect
Example
https://merchant.com/product?cjevent=a1b2c3d4e5If cjevent is missing
The click was registered at the CJ tracking domain before redirect; a stripped cjevent usually still tracks via cookie. Verify with a test click in your CJ dashboard.
How CJ Affiliate tracking fits together
CJ generates links on a rotating set of neutral domains (dpbolvw.net, jdoqocy.com, tkqlhce.com and others) so ad blockers and email filters can’t pattern-match them. The path encodes your PID and the ad ID. On click, CJ registers the event, sets its cookie, and redirects with a cjevent parameter.
A practical gotcha Afterlink’s scanner handles explicitly: several CJ domains fail DNS resolution without the www. prefix. A CJ link that was trimmed to the bare domain — by a CMS, a link shortener, or hand-editing — will not resolve at all.
