Your dashboard has a link builder. Pick or type a source label — linkedin, email, event, newsletter, a client name — and it produces a tagged version of your link, for example:
offerrole.com/partners/r/sp-xxxxxxxxxx?s=linkedin
The tag is recorded alongside the referral when the employer signs up, and your dashboard shows a breakdown of referrals and revenue by source. Attribution behaves exactly the same as an untagged link; the tag only tells you where the person came from.
Source labels are limited to letters, numbers, dashes and underscores (up to 32 characters) and are lower-cased. Anything else is ignored, and the referral is still attributed to you — a malformed tag never costs you credit.
The partner help centre covers attribution, the ledger, payouts and the selling rules.
