About the Brand 4Endurance

Founded by athletes, 4Endurance is a community-driven powerhouse that combines in-house production with expert research to deliver high-quality, science-backed sports nutrition. By integrating real-world feedback and athlete education into their “performance-first” formulas, they have evolved from a local supplement store into a premier European ecosystem that fuels everyone from beginners to professional athletes. Today, they operate across Europe with 12 fully localized markets.

Challenge

The Challenge

By early 2025, 4Endurance had hit a performance plateau. Despite strong brand equity, their fragmented Google Ads infrastructure—burdened by numerous, manual Search campaigns—had reached its limits. This structure created massive operational overhead and starved Google’s machine learning of the data liquidity needed to optimize.

This bottleneck was further intensified by the lack of advanced tracking integration. Operating partially blind without complete conversion signals, Smart Bidding over-indexed on cheap, existing-client retargeting rather than driving new acquisition. Coupled with the saturation of existing markets where the brand lacked strong awareness, expanding into new international locations without precise, real-time data posed too high a financial risk.

Ultimately, the brand was trapped by a rigid baseline that wasted budget on low-value retargeting within saturated markets. To break free, 4Endurance needed to transition into a lean, AI-first architecture powered by pristine first-party data signals to safely scale and fully localize their presence across 12 strategic European markets.

Key Objectives:

  • Surgically Acquire New Users: Shift budget away from the comfort zone of retargeting to aggressively increase new user volume in existing markets.
  • Risk-Mitigated International Scale: Launch, penetrate, and stabilize the brand within 4 new international, localized markets simultaneously.
  • The 7-Figure Revenue Milestone: Move past incremental growth to surpass the 7-figure monthly revenue mark via Google Ads.

Strategy

The Approach

To bridge this gap, 4Endurance transitioned from rigid, manual management to an agile, AI-first ecosystem, guided by Coob Ads as their strategic partner. Operating on the principle that AI is only as good as the data fueling it, the strategy focused on unlocking data liquidity, eliminating signal loss, and aligning product inventory with customer acquisition goals. By feeding Google’s machine learning with high-quality, server-side data, they transformed their infrastructure into an automated international growth engine.

This was achieved through four core pillars:

  • Account Consolidation: Dozens of fragmented manual Search campaigns were consolidated into fewer, high-intent structures, shifting the heavy lifting to Performance Max and Shopping Ads to unlock data liquidity for Google’s AI.
  • Advanced Audience Signals: By combining Google’s Insights Finder with internal first-party data, they built robust audience signals that actively guided the AI to hunt for users with immediate, high purchase intent.
  • Technical Excellence & New Customer Bidding: Deploying CAPI, Enhanced Conversions, and Customer Match allowed them to feed clean data to the system and adjust bidding to heavily prioritize new customer acquisition. This instructed the Smart Bidding algorithm to prioritize driving incremental new user growth, leaving customer retention to be efficiently managed via their own organic channels.
  • Feed & Portfolio Optimization: The product feed was segmented into “New User Drivers” (entry-level, high-margin products) versus “Retention Products” alongside optimized pricing, ensuring assets perfectly matched customer lifetime value.
Success

The Results

Powered by 4Endurance’s precise execution and clear vision, and backed by the strategic guidance of Coob Ads, Google Ads was transformed from a fluctuating marketing expense into a highly predictable revenue engine. By feeding clean data signals via CAPI and Enhanced Conversions, Google’s machine learning optimized efficiently at scale. This removed the bottlenecks that had previously slowed down their growth momentum, enabling the brand to confidently accelerate and capture market share across newly localized regions.

When comparing performance against the previous period (YoY to April), 4Endurance achieved:

+234%

»Working with Coob Ads has been a fantastic experience. Their team has been a great partner in scaling our Google Ads results. We highly encourage other brands to explore the newer campaign types (especially PMAX) and AI-powered features as they have genuinely worked wonders for us. That said, we always stress that the basics must be in place first: flawless tracking (cAPI for purchase events is an absolute must), well-optimised data feeds with strong headlines and visuals, and a competitive product pricing. Get those fundamentals right, and the advanced tools will take you to the next level.«
