Deduplication

TL;DR — Deduplication is how a platform decides which publisher gets credit for a sale when more than one affiliate link was clicked before purchase. Most platforms resolve this with a last-click model, where the most recent click before checkout wins the conversion. On Involve Asia, every affiliate link sets its own tracking, so when a customer clicks multiple links, the platform applies last-click attribution to determine which publisher is credited.

What Is Deduplication?

Shoppers rarely buy after just one click. They might read a review, check a coupon site, then click an influencer’s link before finally purchasing. Each of those clicks could set an affiliate tracking cookie for a different publisher.

Deduplication is the process of resolving this overlap, so only one publisher is credited for the sale rather than several. Without it, an advertiser could end up paying multiple commissions for a single purchase.

The most common approach is last-click attribution: whichever affiliate link was clicked most recently before checkout gets the credit, regardless of earlier clicks from other publishers. This is the standard model across most affiliate platforms.

Deduplication on Involve Asia

When a customer clicks an Involve Asia affiliate link, a tracking cookie is set for that publisher. If the customer later clicks a different affiliate link — from another publisher promoting the same advertiser — before completing their purchase, the most recent click determines who is credited for the sale.

This is why the sequence of clicks matters, particularly for publishers like coupon/deals sites, which are often clicked right before checkout and can end up as the last click in a customer’s journey.
