Affiliate marketing has always occupied an awkward position in the performance marketing hierarchy. Taken seriously by some sectors, treated as a back-channel tactic by many others. In 2026, that division is becoming a competitive disadvantage.
Why the economics are shifting in affiliate's favour
Three things are happening simultaneously. First, Google Ads CPCs have inflated across most commercial categories. The cost per click that was acceptable two years ago now produces ROAS many businesses can't sustain. Affiliate's pay-for-performance model doesn't have that inflation problem.
Second, third-party attribution is becoming less reliable. The multi-touch models that made other channels look good are running on deteriorating data. Affiliate's click-to-conversion model is simpler and more durable under privacy-driven measurement changes.
Third, the creator and publisher ecosystem has matured. The reach available through well-run affiliate programmes - via content publishers, comparison sites, cashback platforms, and creator-driven channels - is real in most consumer categories.
The practical steps
Audit what affiliate activity exists in your category. If competitors are running active programmes and you aren't, that gap has a cost - where comparison sites hold search visibility in particular.
A well-structured programme with clear commission tiers, defined attribution windows, and quality publisher recruitment is materially different from one that's live but passive. The difference in output between the two isn't marginal.
The third step - most often skipped - is integration with the wider paid media strategy. Affiliate and paid search serve overlapping customer journeys in ways that create cannibalisation risks if not managed carefully.
