The Best Attribution Model in Affiliate Marketing: Why It’s About Value, Not Just Clicks

In affiliate marketing, few topics spark more debate than attribution. Which partner should get credit for a sale? How do you measure and reward true partner value?

The short answer: there is no single “right” attribution model. The industry default across most affiliate networks is last click attribution, but that doesn’t mean it’s the best fit for every program.

The real opportunity lies in shifting the conversation from where a partner was in the clickstream to what value they delivered in the customer journey.

Why Last Click Attribution Remains the Standard

Under last click attribution, the affiliate responsible for the final click before conversion receives the commission.

This approach is common for a reason:

• Simplicity – Easy to implement, easy to understand, and supported by all major affiliate networks.

• Purchase proximity – The last click often represents the final push before a sale.

• Established precedent – With years of adoption, last click is widely accepted and operationally straightforward.

For example, if a shopper first discovers your brand through a blog review, later finds a coupon on a deal site, and finally clicks a cashback offer before purchasing, the cashback partner would earn the commission under last click rules.

The Limitation: Ignoring the Full Customer Journey

Last click attribution simplifies tracking, but it overlooks the reality that multiple partners may have influenced the purchase.

Consider the roles different affiliates can play:

• Content publishers introduce the brand and build trust early in the decision process.

• Deal or coupon sites provide urgency and pricing incentives.

• Loyalty platforms offer a final incentive to convert.

By rewarding only the last partner in the chain, brands risk undervaluing those who create early interest and consideration — partners who often require more effort and resources to generate engagement.

Why a Multi-Touch Perspective Adds Value

Multi-touch attribution recognizes that two or more affiliates can contribute meaningfully to a single sale. Instead of assigning 100% of the credit to the last click, it evaluates the role each partner played in the path to purchase.

A few approaches include:

• Assist tracking – Recording earlier partner interactions even if they weren’t the final click.

• Weighted attribution – Allocating percentages of commission based on each partner’s influence.

• Hybrid models – Keeping last click as the base but rewarding earlier influencers with bonuses or incentives.

This broader view can strengthen relationships with top-of-funnel partners who drive awareness and brand consideration — critical contributors to long-term growth.

Should You Split the Commission?

When multiple affiliates contribute to the same sale, brands often ask: Should we split the payout?

There is no universal answer. Some brands split proportionally based on influence or timing, while others maintain a primary winner but offer smaller “assist” payments.

Factors to consider include:

• Program objectives – Growth, margin control, or brand exposure.

• Affiliate mix – Content creators, influencers, deal sites, loyalty platforms, and beyond.

• Category competitiveness – How partners compete for visibility.

• Technology capabilities – What your tracking platform can support.
