The Quiet Reinvention of Affiliate Marketing

For years, affiliate marketing has enjoyed something few marketing disciplines can claim: it has almost always been able to prove its value. Pay for outcomes. Measure every click. Track every sale. In an industry obsessed with accountability, affiliate had all the makings of a poster child for performance.

So why do so many marketers still struggle to answer a surprisingly simple question: What exactly is affiliate marketing today?

The collapse of the traditional channel definition

Affiliate is still talked about as though it still operates within a specialist channel with its own agencies, technologies and budgets. In reality, the mechanics that once made affiliate distinctive have escaped the confines of the affiliate ecosystem.

Creators earn affiliate commissions through platforms like Impact or Amazon Associates. Retail media networks such as Amazon Ads, Walmart Connect and Tesco Media operate on affiliate-like performance principles. Influencer agencies increasingly negotiate hybrid deals that include performance-based payouts. Commerce teams optimise conversion across Shopify storefronts and DTC journeys. Paid social increasingly works alongside creator partnerships with measurable commercial outcomes, especially on TikTok Shop where content and checkout are tightly linked.

The commercial model has spread far beyond the traditional channel.

From channel to commercial infrastructure

Ironically, this is good news for affiliate marketing – but not necessarily for affiliate agencies.

Historically, affiliate agencies differentiated themselves through publisher relationships, voucher networks, cashback programmes like Rakuten, and performance optimisation. Those capabilities still matter, but they are no longer enough. The conversations marketers are having today are broader. They want to know how affiliate alongside GEO, creators, retail media, CRM, paid social, and commerce – not how it operates in isolation.

The has question has shifted from “Who runs affiliate?” To “Who orchestrates commercial performance?” That distinction matters.

Influencer and affiliate are converging, yet organisations remain fragmented

As influencer marketing matures, brands are under increasing pressure to move beyond vanity metrics. Engagement alone is no longer sufficient. Commercial outcomes matter.

Unsurprisingly, more creator programmes now include affiliate-like mechanics, unique tracking links, promotional codes and performance incentives – think of how fashion brands like SKIMS or Gymshark routinely equip creators with trackable discount codes that directly tie content to revenue.

Influencer is becoming measurable. At the same time, affiliate is becoming creative. The boundary between the two continues to blur.

Yet many organisations still manage them through different teams, different agencies, different technologies and different KPIs. One team optimises creators. Another manages affiliates. A third oversees commerce. Each reports success differently while competing for the same consumer journey. That is not specialisation. That’s fragmentation.

Rethinking what an affiliate agency is for

This creates an uncomfortable question for marketers reviewing their agency ecosystem. Do you really need a standalone affiliate agency? Or do you need a partner capable of integrating affiliate capability into broader commerce and creator strategy?

The answer won’t be the same for every organisation. Highlight regulated sectors, complex international publisher ecosystems or sophisticated retail partnerships may still justify specialist expertise.

But many brands should stop selecting agencies based on whether they “do affiliate” and start asking whether they understand how commercial influence works today.

• Can they integrate creators with affiliate economics?
• Can they balance brand building with measurable performance?
• Can they navigate retail media, partnerships, influencer and commerce as a connected ecosystem rather than competing silos?

Three key observations

1. Affiliate is no longer a channel, it is a layer: Affiliate mechanics sit across creator marketing, retail media, commerce platforms, and paid social. Treating it as a standalone discipline underestimates its role in the wider performance ecosystem.
2. Influencer and performance are inseparable: Creators are no longer just awareness drivers. With codes, links, and commerce integrations, they are direct contributors to revenue. Influencer without measurement is disappearing.
3. Organisational silos are the real constraint: The biggest barrier to performance is not technology or partners, but internal fragmentation. Teams optimising different parts of the same journey are often competing rather than collaboration.

The future belongs to connected commercial models

Affiliate marketing itself is unlikely to disappear. If anything, its commercial principles are becoming embedded across modern marketing. The paradox is that affiliate marketing may have won precisely because it no longer belongs exclusively to the affiliate industry.

And that’s why the next generation of agency reviews shouldn’t be asking who has the strongest affiliate credentials. They should be asking who is best equipped to build a connected commercial growth model.

If your organisation is still evaluating affiliate, influencer and commerce separately, you are likely optimising fragments rather than outcomes. Now is the time to rethink how these disciplines connect.
