Marketing Attribution Ignores Affiliate Link Fragmentation

Episode notes

Episode 126 of Marketing Analytics with Fexingo takes on one of attribution's most stubborn blind spots: affiliate link fragmentation. Lucas and Luna unpack how brands like REI and Target lose track of conversions when customers click one affiliate link but buy later via a different path, or when publishers use multiple sub-networks. They walk through real data from a 2025 affiliate audit that found 38% of commissionable conversions were never attributed to the right partner. The hosts discuss the rise of server-side affiliate tracking, the role of postback URLs, and why last-click still dominates despite the distortions. They also touch on how Amazon Associates' 24-hour cookie window exacerbates the problem. By the end, you'll understand why your affiliate program might be underpaying top partners and overpaying dead ones - and what to do about it. #MarketingAnalytics #Attribution #AffiliateMarketing #AffiliateLinks #ConversionTracking #LastClick #CookieWindow #ServerSideTracking #PostbackURLs #REI #Target #AmazonAssociates #CommissionTracking #LinkFragmentation #MarketingROI #Business #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
