EU Opens Antitrust Investigation on Google’s AI Content Use – What Affiliate Marketers need to know

The European Commission has launched a formal antitrust investigation into Google's use of web publisher content and YouTube videos for artificial intelligence purposes, marking a significant regulatory intervention that could reshape how affiliate marketers and publishers navigate AI-powered search ecosystems. The probe, announced December 9, 2024, examines whether Google has breached EU competition rules by using content without appropriate compensation whilst simultaneously disadvantaging rival AI developers.

The Two Critical Areas Under Investigation

The Commission's investigation targets specific practices that directly impact affiliate marketing operations. 

First, regulators are examining whether Google's AI Overviews and AI Mode features draw from publisher content without providing adequate compensation or offering publishers meaningful options to refuse such use without losing search visibility. 

Second, the investigation scrutinises YouTube's policies requiring creators to grant Google permission to use uploaded content for training generative AI models, with no additional compensation and no opt-out mechanism whilst maintaining platform presence.

For affiliate publishers who have already experienced significant traffic declines from AI Overviews, the investigation represents options for potential relief. 

Recent data shows AI Overviews now appear in over 35 percent of US Google desktop searches, with organic click-through rates for top-ranked positions dropping by 34.5 percent when these features appear. Google's top organic CTR has plummeted from 28 percent to 19 percent following AI Overview expansion, a 32 percent decline that directly impacts affiliate revenue models dependent on referral traffic.

The Competitive Dynamics at Stake

The Commission's concerns extend beyond publisher compensation to address competitive fairness in the emerging AI market. Teresa Ribera, Executive Vice-President for Clean, Just and Competitive Transition, emphasised that AI innovation cannot come at the expense of democratic principles. The investigation will assess whether Google's dominant position in search and online video provides privileged access to vast content stores, effectively placing rival AI developers at a structural disadvantage whilst forcing publishers to accept unfavourable terms.

This competitive dimension matters for affiliate marketers because it could determine whether alternative AI platforms gain sufficient access to content libraries to challenge Google's search dominance. The investigation examines whether publishers genuinely possess the freedom to refuse content use for AI purposes, or whether dependence on Google Search for traffic creates an economic compulsion to accept terms they would otherwise reject.

Immediate Implications for Affiliate Program Managers

Affiliate managers should monitor three specific areas as this investigation progresses. 

The probe could establish precedents for AI content licensing that affect how publishers negotiate with technology platforms. 

If the Commission determines Google must compensate publishers for AI training data, similar requirements could extend to other AI platforms accessing affiliate content, potentially creating new revenue streams but also complicating content distribution strategies.

The investigation's findings could influence how AI-generated summaries incorporate affiliate links and attribution. 

If regulators mandate clearer pathways for users to reach original content sources, affiliate marketers might see partial recovery of traffic lost to zero-click searches. However, this remains speculative until the Commission's findings provide concrete guidance on acceptable AI content practices.

Publishers using AI-generated content for affiliate marketing should review their content creation processes. 

Whilst the investigation focuses on Google's practices rather than publisher behaviour, increased regulatory scrutiny of AI content usage across the ecosystem may prompt platforms to implement stricter content authenticity requirements that affect how affiliate sites deploy certain AI and content generation tools.

Strategic Considerations for Publishers

Publishers should prepare for potential regulatory changes and outcomes by diversifying traffic sources and strengthening owned media channels. The investigation timeline remains uncertain, with no legal deadline for completion, meaning affiliate marketers cannot rely on regulatory intervention to restore search traffic in the near term. 

Email list building, social media presence, and direct traffic strategies become more critical as the search landscape continues evolving regardless of regulatory proceedings.

Content strategy requires particular attention. Publishers should continue focusing on experience-led content that demonstrates genuine product knowledge and firsthand testing, as this content type remains difficult for AI systems to replicate and provides clearer value proposition regardless of how search interfaces evolve. The investigation may eventually clarify fair use boundaries for AI training data, but quality content with authentic expertise will remain valuable under any regulatory framework.

Program managers should also consider the broader implications for their managed partner relationships. If the investigation results in stricter content licensing requirements, smaller publishers may face challenges monetising their content across multiple platforms, potentially affecting their willingness to participate in affiliate programmes with lower commission rates.

Understanding these economic pressures helps program managers structure competitive offers that maintain publisher loyalty during periods of regulatory uncertainty.

Looking Beyond the Investigation

The probe represents one element of Europe's broader approach to regulating AI technology and platform power. Recent actions include a €120 million fine against X for transparency violations and an investigation into Meta's WhatsApp data-sharing policies, demonstrating the Commission's willingness to enforce existing competition frameworks against AI-related practices. For affiliate marketers, this regulatory environment suggests continued scrutiny of how platforms monetise content and distribute traffic.

Google's response emphasising innovation risks and market competitiveness indicates the company will mount a robust defence. The investigation's duration depends on case complexity, Google's cooperation, and legal proceedings, meaning resolution could take years rather than months. Affiliate marketers should therefore focus on operational resilience rather than expecting rapid regulatory intervention to address immediate traffic challenges.

The investigation also raises questions about AI content creation by affiliate publishers themselves. Whilst the probe examines Google's use of publisher content for AI training, the broader regulatory discussion around content authenticity and value could eventually affect how affiliate sites deploy AI writing tools.

Publishers should maintain documentation of their content creation processes and ensure AI-assisted content meets quality standards that provide genuine value to readers, as regulatory frameworks continue developing.
