Premier League Websites for MarTech

As part of the JDS Investigates series, this technical audit analyzes the advertising and data maturity of top Premier League clubs, including Liverpool F.C., Arsenal F.C., Chelsea F.C. and Manchester United F.C. We evaluate these multi-million pound global brands across six critical pillars: Consent Management (CMP), Tag Management (sGTM/Client-side), Site Analytics, Data Management (CDP/1PD), Marketing Tags and Publisher Ad-Server infrastructure as of late 2025. This analysis reveals the gap between global brand prestige and actual MarTech implementation maturity.

  • Tag Management Trends: While Google Tag Manager remains the industry standard, clubs like Manchester United diverge with the Adobe Launch ecosystem.

  • Server-Side Adoption: Adoption of Server-Side GTM (sGTM) is currently low across the league, with Chelsea F.C. leading the way in more robust server-side implementations for Meta and TikTok.

  • Consent Discrepancies: Audit shows varying levels of compliance; while Chelsea and Man Utd offer robust "Reject All" options, other clubs still fire tags prior to user consent or lack clear opt-out paths.

  • First-Party Data Maturity: Most clubs rely heavily on client-side marketing tags, though Manchester United shows advanced 1PD maturity through Lytics and Salesforce integrations.
