Rethinking Affiliate Attribution for a More Complex Customer Journey

Affiliate marketing has faced intense debate in recent years. Controversies involving Honey, Phia, and, most recently, ShopMy have brought affiliate attribution into the mainstream marketing conversation. Each situation involves different technology, behavior, and commercial considerations, but all reveal a shared challenge: traditional attribution models do not capture the complexity of today’s customer journey.

The path to purchase is rarely linear. A consumer may have several meaningful interactions across discovery, consideration, and conversion, yet traditional affiliate attribution typically awards the entire commission to the last eligible click.

These controversies expose the model’s limitations, not a fundamental flaw in affiliate marketing. The channel has moved far beyond perceptions of low-value, incentive-based activity. Today, it is a dynamic ecosystem of outcome-based partnerships that can both create and convert demand.

Affiliate management must now evolve alongside the channel. For PMG, this moment reinforces the value of managing affiliate as an integrated, outcome-based partnership discipline, supported by stronger governance, more sophisticated measurement, and compensation strategies that reflect how partners contribute across the customer journey.

Three Controversies Reveal Three Attribution Gaps

Honey Shows How the Last Click Gets Too Much Credit

Beginning in late 2024, creators and publishers alleged that Honey replaced their affiliate tracking when shoppers interacted with the extension at checkout, sometimes without providing a meaningful discount. Honey disputed the allegations and maintained that it followed standard last-click practices. The controversy exposed the gap between attribution and contribution: an extension may generate the final eligible click without creating demand or exerting the greatest influence on the purchase. In March 2025, Google updated its Chrome Web Store policies to require direct, transparent consumer benefit, intentional user action, and clear disclosure before an extension can use affiliate tracking.

Phia Shows Why User Intent Must Come First

The Phia allegations raised a more direct compliance concern. In July 2026, independent research and media reports alleged that its browser extension inserted affiliate tracking at checkout without intentional shopper interaction. PMG independently reproduced the reported behavior, assessed exposure, and worked with networks and subaffiliate partners to exclude Phia where appropriate. Phia attributed the issue to a software update and said it had resolved the behavior. 

Affiliate networks later reported reprocessing affected transactions by reattributing them to the appropriate publisher or refunding advertisers. Unlike the Honey debate, which centered on the value of a valid final interaction, the Phia situation centered on whether a valid interaction occurred at all. It reinforced intentional consumer action as a foundational requirement for affiliate attribution.

ShopMy Shows What Happens When Two Platforms Claim One Order

The scrutiny involving ShopMy reflects a different challenge: duplicate attribution across separate affiliate systems. Brands can work with ShopMy through a primary affiliate network or through a direct relationship. When both operate together, the systems track journeys independently and may claim the same transaction. Criticism centered on now-archived ShopMy guidance recommending that brands retain its commission and cancel the duplicate in their other network, even when that network may have recorded the true final affiliate click. 

PMG’s analysis of two programs found that 10% to 15% of ShopMy-attributed orders also appeared in the corresponding brand’s affiliate network. Those overlaps represented only 0.25% to 1.5% of total affiliate orders and typically involved a creator touchpoint followed by a cashback or coupon partner. The issue is not necessarily invalid tracking, but the lack of shared attribution logic and the need for brands to quantify and deliberately manage the overlap.

Attribution Is Not Contribution

Across all three controversies, the issue is not that last-click attribution lacks value. It provides a clear, scalable rule for assigning transaction credit. The problem arises when that interaction becomes a complete measure of contribution and the sole basis for investment decisions. Research from impact.com found that consumers engage with brands at least three times across digital channels before purchasing, rising to five or more touchpoints among higher-income consumers. 

Brands are no longer limited to that view. Leading affiliate platforms report on click paths, time to conversion, assisted conversions, customer status, and partner interactions, revealing where publishers influence the journey. They also turn those insights into action through differentiated rates, preferred crediting, shared commissions, extended attribution windows, and incentives tied to outcomes such as new-customer acquisition or specific product sales.

These capabilities let brands maintain clear transactional attribution while rewarding partners for the roles they play. A creator or editorial publisher that introduces new customers may warrant different economics than a cashback partner that closes the sale, even when the latter receives the final click. When partners operate across separate platforms, as with ShopMy and a traditional network, brands must combine the data and establish reconciliation logic to achieve the same visibility.

The opportunity is to place last-click attribution within a more intentional framework—one that distinguishes credit from contribution and directs investment toward the partners and behaviors creating the most business value.

Affiliate Remains a Strong Investment When It’s Actively Managed

Scrutiny of attribution does not diminish affiliate marketing’s value. It reinforces the importance of active program management.

At its core, affiliate offers a compelling economic advantage: compensation can be tied directly to a measurable action, whether a purchase, qualified lead, app install, subscription, or other defined outcome. This creates an accountable, often highly efficient investment model, with flat-fee funding added selectively when an opportunity to create demand warrants it.

Affiliate is far more than a single tactic or publisher type. Its ecosystem spans creators, editorial content, loyalty, card-linked offers, and emerging commerce technology. Publishers such as tvScientific show how affiliate infrastructure can bring outcome-based economics to traditionally impression-led environments such as CTV. The channel’s breadth and scale connect it to nearly every other media and marketing practice.

Consumers do not distinguish between an “affiliate” touchpoint and a creator post, product review, cashback offer, or media placement—they experience one journey. PMG therefore approaches affiliate as a performance layer across marketing efforts, connecting partnership strategy with creator, content, commerce, and broader media activity. Trackable partnerships can amplify campaigns, open new distribution points, and scale media activity against measurable outcomes.

This role is becoming more valuable as discovery evolves. Editorial reviews, product roundups, and comparison content supported by affiliate programs increasingly inform AI-generated answers. Recent research found articles and listicles among the most-cited formats, with comparison pages achieving the highest citation rate once retrieved. Affiliate cannot guarantee citations, but it gives brands an actionable way to build publisher relationships and support useful third-party content that may strengthen visibility in AI-generated answers.

The channel’s transaction-level transparency also makes it highly accountable. PMG uses this visibility to audit partner activity, customer journeys, and commissions; identify anomalous behavior; and inform investment and governance decisions. These controversies are visible precisely because affiliate programs produce detailed, actionable data.

The greatest risk lies not in affiliate itself, but in underusing its flexibility or treating a program as “set it and forget it.”

Build a More Resilient Affiliate Program

Brands need not react to every attribution concern by removing entire partner categories. PMG advocates an evidence-based approach that assesses an issue’s behavior, scale, and business impact before determining the response. The goal is to protect program integrity without limiting the innovation and partner diversity that make affiliate valuable.

Make User Intent Non-Negotiable

Intentional consumer action should be foundational—full stop. PMG crafts program terms that define valid interactions and prohibit forced clicks, hidden redirects, and background tracking. Higher-risk technologies should be tested across devices and customer scenarios. When concerns arise, PMG works with publishers, networks, and subaffiliate partners to validate the issue, quantify exposure, and implement remediation.

Evaluate Partners by the Roles They Play

Partners should be evaluated by their role in the journey, not ranked solely by last-click revenue. PMG centralizes platform reporting and customer data within Alli, our proprietary marketing intelligence platform. Alli combines click paths, time to conversion, new-customer rates, order values, engagement, and incrementality to assess impact beyond the last click. PMG uses those signals to form a directional view of how partners contribute to discovery, consideration, and conversion, refining investment decisions over time. 

Match Compensation to Contribution

PMG views commissioning as a strategic investment lever, not a fixed reward for the final click. Differentiated rates, preferred attribution, new-customer bonuses, product-level terms, and partner-specific incentives help brands reward the outcomes and behaviors that matter most. The goal is not to split every commission across every touchpoint, but to reflect each partner’s broader contribution over time.

Set the Rules Before Systems Overlap

A centralized affiliate network generally provides the cleanest attribution, but direct platform relationships may justify added complexity. Before launching one, PMG recommends quantifying potential overlap and setting a clear reconciliation policy. When duplication is limited and both partners contribute, brands may accept controlled overlap while adjusting rates to keep the combined economics sustainable. Also, because AI-generated answers cite publisher content without necessarily driving a click, brands may need to complement commissions with selective content investments that recognize a partner’s potential contribution to visibility and consideration.

Make Oversight an Always-On Practice

Partner approval is only the beginning of compliance management. Always-on Alli alerts provide foundational protection by flagging unusual changes in clicks, conversion rates, transaction patterns, or partner performance. Those alerts should be paired with audits, test purchases, subaffiliate transparency, and human review to distinguish genuine growth from potential attribution issues.

Move Affiliate Forward Without Losing Control

Affiliate has long been a proving ground for innovation, creating new publisher models and extending performance-based partnerships into new areas of media and commerce. That evolution will continue, creating tremendous opportunity and a responsibility to ensure innovation does not outpace the controls needed to evaluate it.

Attribution will become more complex as these ecosystems expand. Across hundreds of partnerships, a single purchase may reflect several meaningful interactions. No click can fully explain that journey, and no universal attribution rule will suit every brand, category, or partner mix.

PMG’s role is to help brands design partnership ecosystems in which media objectives, commercial terms, measurement, and governance work together. Affiliate programs should reflect each brand’s economic priorities and the channel’s contribution to the broader customer journey rather than operate in isolation. When innovation and oversight advance together, brands can explore new partnership models, make more informed investments, and grow without compromising integrity.
