Affiliate tracking: last-click vs first-click (simple explanation)

A simple way to choose an attribution rule you can defend during payouts

Last click vs first click attribution

Last click versus first click is a fairness choice. Last click rewards closers. First click rewards openers. The wrong rule creates constant arguments, even if tracking works perfectly.

Table of contents

Definition

First click attribution gives credit to the first affiliate who referred the customer. Last click gives credit to the last affiliate touch before purchase.

Options and tradeoffs

First click

Rewards discovery and top of funnel. Breaks when partners do a tiny early touch and then disappear.

Last click

Rewards closers and comparison content. Breaks when early referrers feel they never get paid.

For most small SaaS affiliate programs, last click within a 30 day window is the simplest default. If you want to reward discovery, add a bonus program later instead of changing attribution rules.

Copy/paste template

Attribution: We attribute conversions to the last affiliate link click within 30 days before purchase.

FAQ

Is last click unfair?

Pick a rule you can publish in one sentence. That is the rule you can defend.

Next step today: publish your attribution window and whether you use first click or last click.
