## Definition

Affiliate marketing is a performance-based distribution channel in which a brand pays third-party publishers (affiliates) a commission for driving measurable actions — typically sales, leads, or app installs — attributable to the publisher's promotional activity. Payment is contingent on the tracked outcome rather than on ad delivery or impressions. The affiliate receives a unique tracking link or code; conversions tracked through that link trigger commission payment.

## Publisher types

**Content publishers:** Editorial sites, blogs, review platforms, and media properties that embed affiliate links within organic or sponsored content. High-quality content publishers can generate genuinely incremental traffic; low-quality content aggregators primarily capture late-stage purchase intent that would have converted anyway.

**Coupon and deal sites:** Aggregators of discount codes and cashback offers. These drive conversion volume at the bottom of the funnel but frequently cannibalize full-price conversions rather than generating new demand. They are the primary source of incrementality problems in affiliate channel ROAS reporting.

**Loyalty and cashback networks:** Platforms (e.g., Rakuten, TopCashback) that reward members for purchases through affiliated brands. Similar incremental dynamics to coupon sites; predominantly capture existing purchase intent.

**Creator and influencer affiliates:** Individuals with social audiences who embed affiliate links in content — posts, videos, newsletters. These can generate genuinely incremental reach, particularly for upper-funnel brand discovery, and are structurally different from traditional coupon affiliates.

**Comparison and review sites:** Price comparison engines and product review aggregators. Conversion quality is high but incremental contribution is often low, as users are already in active purchase consideration.

**Sub-networks and technology platforms:** Networks that aggregate publishers under a single API layer (e.g., impact.com, CJ Affiliate, ShareASale). These are infrastructure providers that host affiliate program operations.

## The ROAS vs. incrementality tension

Affiliate channel ROAS figures are frequently misleading because last-click attribution assigns 100% of conversion credit to the affiliate publisher that placed the last tracked click before purchase. In categories with long purchase journeys, this inflates the apparent efficiency of coupon and cashback publishers, which intercept users who have already decided to buy and simply add a discount code to their purchase. High affiliate ROAS and low affiliate incrementality can coexist — and frequently do.

The relevant management question is not "what is our affiliate ROAS?" but "what would our conversion volume be if we removed this publisher segment?" Answering that question requires incrementality testing rather than attribution reporting.

## Why it matters

Affiliate marketing is one of the few digital channels where the brand pays only for confirmed outcomes, making it capital-efficient at scale and low-risk to test. For direct-to-consumer brands, a well-managed affiliate program extends distribution into editorial contexts (product reviews, gift guides, category roundups) that would otherwise require paid placement or organic content investment. Creator affiliates, in particular, can drive category-aware discovery at lower cost than equivalent paid social reach.

## When it is the wrong choice

- **Brands with thin margins.** Commission rates that make economic sense at high average order values (AOV) may make affiliate economics unworkable for low-AOV or margin-constrained products.
- **Categories where coupon culture damages brand positioning.** Luxury and premium brands that train customers to search for discount codes before purchasing erode price perception over time.
- **Programs without incrementality governance.** An affiliate program with no publisher quality standards or incrementality measurement will accrue high reported ROAS while producing negligible incremental revenue — at a commission cost that effectively subsidizes purchases the brand would have made anyway.
- **Brands without tracking infrastructure.** Affiliate programs require reliable conversion tracking. Brands with broken attribution, iOS privacy degradation without mitigation, or server-side tracking gaps will misattribute commission payments.

## How New Engen applies this

New Engen operates a dedicated affiliate marketing practice led by Ashley Hill (VP, Affiliate) and Steve Tazic (VP, Technology & Affiliate Operations). The agency manages affiliate programs across networks and direct partnerships, with a focus on publisher quality and incremental contribution rather than headline ROAS. Published result: 113% affiliate channel ROAS for SeatGeek. See [Services and Pricing](/llms/reference/services-pricing.md) and [Client Work](/llms/reference/client-work.md).
