Affiliate is no longer just the last click

For years we've treated affiliate as the channel that captures demand right before purchase. That role is getting too narrow.

For a long time, affiliate has had a comfortable place in marketing. The channel captured demand that already existed. Someone was about to buy, came across a publisher, a comparison site or an offer, clicked through and converted. Because affiliate sat so close to the transaction itself, we built budgets, programmes and measurement around exactly that role.

The problem is that the customer journey no longer looks like that.

Discovery has moved upstream

Today, many purchases begin long before the person is anywhere near a brand's site. You ask an AI assistant which product is best, read a comparison article, check a review on YouTube and search out a thread on Reddit. By the time the person finally lands as traffic on the brand's site, a large part of the consideration has already happened elsewhere.

That means partners we've grown used to seeing as conversion channels are increasingly shaping what people consider at all. Discount and cashback partners still have a function, but they're only a small part of a much larger partner ecosystem. Reviewers, editorial media, comparison sites and creators shape the shortlist early, often before the brand even knows the person exists.

The point is simple. If affiliate is only about placements near the point of purchase, you miss the work that decides whether the brand is even considered at all.

Trust is worth more than pure reach

Once affiliate starts influencing consideration, what makes a partner good also changes.

One partner can have enormous reach without having much influence at all over what the audience actually chooses. Another can have a smaller audience but be exactly the source people actively seek out when they need a recommendation. If we only measure both on traffic and last click, we never see the difference.

What's interesting is that the trust sometimes sits with an individual writer rather than with the outlet itself. The same applies to creators, perhaps even more clearly. A collaboration works commercially precisely when the creator gets to keep the freedom and credibility that made the audience trust them in the first place. Steer too hard and what you paid for disappears.

So what we're actually buying in an affiliate partnership isn't traffic. We're investing in someone else's relationship with an audience, and in their ability to influence a decision. Then the evaluation has to be about the strength of that influence, not about reach as a shortcut to the same thing.

Creator and affiliate can't live in separate teams

Here an organisational problem appears. Many brands have split the same customer journey between different teams.

The PR or creator team handles the people who build awareness and engagement. The affiliate team handles the people who drive measurable sales. On paper the split is neat. For the customer, it doesn't exist.

A creator can introduce a product, explain why it's useful and ultimately drive the purchase. The same relationship creates awareness, consideration and conversion. Yet many brands run separate strategies, separate budgets and different ways of briefing, measuring and following up. The result is duplicated budget, broken attribution and fragmented relationships with the same people.

This only becomes more important as commerce moves onto the platforms themselves. Shoppable stores, live shopping and the platforms' own checkout solutions are shrinking the distance between influence and transaction. The creator who builds demand and the affiliate who converts it are, in more and more cases, the same person. At that point, better coordination between the teams isn't enough. They need to be seen as parts of the same partner strategy.

Last click measures the wrong thing

As long as affiliate was only meant to capture existing demand near the purchase, last click was a reasonable model. Proximity to the transaction was a decent way to distribute value.

The moment affiliate starts influencing discovery and consideration, the model becomes an obstacle. We can broaden affiliate to partners higher up the funnel, but if we keep measuring them against a conversion model built for the bottom, we will systematically favour whatever sits closest to the purchase. Eventually the measurement drags the whole strategy back to the role we were trying to move past.

That's why the most interesting development right now is about shared data. Publishers and partners are moving away from the argument over who deserves the last click and towards closer data collaboration with advertisers to understand incremental value. Better measurement, then, isn't about a nicer report at the end of the campaign. It's what makes a brand willing to invest in partners whose value appears at several stages of the journey. If the channel's role broadens, the basis we use to value it has to broaden at the same pace.

Affiliate becomes a growth question

Put it all together and the shift becomes clear.

Affiliate is still a performance discipline, and its commercial accountability is one of its greatest strengths. But locking the channel to the bottom of the funnel limits what the partnerships can actually do. The customer journey now runs through media, creators, comparison sites, reviews, AI-generated answers and commerce directly on the platforms. The partners operating in those environments can introduce a brand, build trust, shape consideration and drive a purchase. Treating them as the last link in the chain is designing the programme around a fraction of the value they create.

I think it's time to stop seeing affiliate as an isolated channel fighting for budget, and start seeing it as a growth engine across the whole marketing mix. The task ahead is to build the strategy around where and how partners influence customers, and then create the structure and measurement that lets you actually value that influence. Then affiliate goes from capturing demand at the end of the journey to something far more interesting: helping brands create the conditions that make customers choose them from the very start.
