Retargeting can be a valuable part of an affiliate program. It can bring an undecided customer back, recover an abandoned journey and help close a sale that might otherwise have been lost.<\/p>\n\n\n\n

But what happens when a retargeting partner appears at the end of a customer journey without meaningfully contributing to the conversion, and a last-click attribution model automatically gives it the credit?<\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

That was the situation faced by one of our clients.<\/p>\n\n\n\n

After moving its affiliate program to TrafficManager, the company was able to examine complete conversion paths instead of looking only at the affiliate attached to the final conversion. The new visibility revealed a pattern of suspicious retargeting touchpoints that appeared shortly before orders and displaced the partners that had actually introduced or influenced the customers.<\/p>\n\n\n\n

The client estimated that similar attribution had cost the business hundreds of thousands of euros over several years on its previous setup. It ultimately chose to pursue legal action against the affiliate involved.<\/p>\n\n\n\n

This is not a story about retargeting being inherently bad. It is a story about why attribution should reflect contribution, and why the last recorded click should never be accepted without context.<\/p>\n\n\n\n

The problem with treating the last click as the whole story<\/h2>\n\n\n\n

Traditional last-click attribution answers a very narrow question:<\/p>\n\n\n\n

\n

Which affiliate generated the final recorded click before the conversion?<\/p>\n<\/blockquote>\n\n\n\n

It does not necessarily answer the more important question:<\/p>\n\n\n\n

\n

Which partners genuinely contributed to the customer journey and should be paid for it?<\/p>\n<\/blockquote>\n\n\n\n

Those questions often produce the same answer. Sometimes they do not.<\/p>\n\n\n\n

A customer may first discover a brand through a content affiliate, return through a paid campaign, receive a retention email and finally see a retargeting ad. Crediting only the final touchpoint can undervalue every earlier contribution.<\/p>\n\n\n\n

The risk becomes more serious when the final click was not the result of an intentional customer interaction at all. A tracking link can potentially be fired through a pixel, an embedded frame or another background mechanism. If the attribution platform records that event as an ordinary click, the affiliate can appear to have closed a sale even though the customer never knowingly followed its link.<\/p>\n\n\n\n

This type of suspected attribution manipulation is often described as cookie stuffing or conversion stealing. A single unusual click is not proof of abuse, but a repeated pattern can justify a deeper investigation.<\/p>\n\n\n\n

What the client was seeing<\/h2>\n\n\n\n

The client worked with several categories of acquisition partners, including active affiliates, paid sources, retention channels and passive or retargeting partners.<\/p>\n\n\n\n

Under the previous attribution logic, a retargeting affiliate could receive credit simply by being present in the click flow or by becoming the final recorded touchpoint. That made it difficult to distinguish between a partner that genuinely brought the customer back and one that had merely inserted itself into a journey that was already converting.<\/p>\n\n\n\n

Once the full path became visible, several warning signs appeared:<\/p>\n\n\n\n
