Introduction : when two expertises come together

In 2026, digital marketing has become increasingly complex. Brands operate in a fragmented environment: more channels to manage, widespread advertising automation, and marketplaces that now play a central role. These changes promise efficiency and growth, but they also bring two challenges: reduced visibility and limited alignment between media investments and actual sales.

Welcome to our new series “Discover our key partners.” With this initiative, we showcase how we at blue2purple extend our expertise by working with leading players in the digital economy. Each collaboration demonstrates how combining strengths creates greater value and measurable results for brands.

For this first one, we focus on our partnership with eTAIL agency, a specialist in marketplace activation and optimization. Together, we connect strategy with execution, helping brands regain clarity and performance.

Marketplaces : the new strategic ground for brands

Marketplaces now account for a significant share of e-commerce growth. Platforms such as Amazon, Cdiscount, Bol.com, and ManoMano attract millions of customers, dominate product searches, and generate substantial sales volumes. For brands, not being present means losing visibility and market share.

Performing well on these platforms, however, is complex:

• Optimizing product pages and internal SEO.
• Managing logistics flows (FBA, FBM, hybrid models).
• Running marketplace ads (Amazon Ads, Cdiscount Ads) in line with broader digital strategies.
• Keeping margins under control through PnL monitoring while handling special events like Prime Day or Black Friday.

eTAIL agency : turning presence into growth

This is where our partner eTAIL agency brings its unique value. They have built their reputation on addressing these marketplace challenges from end to end: optimized catalog creation, sponsored campaign management, logistics oversight, and PnL monitoring. Their mission is clear: to turn marketplace presence into sustainable business results.

Client success stories

• Maison Berger Paris: +112% traffic on Amazon and +33% increase in average basket size following content optimization and a tailored commercial strategy.
• Bemini: +25% conversion rate after product page redesign and improved SEO.
• Logicom: +30% traffic and better advertising CoS control through catalog and campaign optimization.
• Marilou Bio: tripled revenue on Amazon after improving visibility, branding, and enriched content.

These cases highlight the variety of issues addressed : increasing traffic, improving conversion rates, managing margins, and driving revenue growth.

Advertising automation : a lever that needs guidance

At the same time, advertising automation has reshaped how brands manage media. Formats such as Performance Max, Advantage+, and AI Max offer simplified configuration and continuous optimization.

The benefits are clear: faster execution and less operational complexity. But there are also limits:

• Opacity: reduced visibility into audiences, queries, and budget allocation.
• Standardization: campaigns often look alike, limiting differentiation.
• Dependence: brands rely heavily on platforms that control the data.

blue2purple : providing structure and clarity

This is where we at blue2purple come in. We help brands prepare strategically: defining clear business objectives, selecting the right signals (CRM data, customer lifetime value, segmentation), and setting the right exclusions. It also develops advanced measurement models such as multi-touch attribution, consolidated dashboards, and incremental analysis.

In practice, this approach makes automation a tool that serves strategy, not the other way around.

Building a consistent omnichannel approach

Too often, advertising and marketplaces are treated as separate areas:

• Media teams analyze conversions reported by advertising platforms.
• Marketplace teams focus on revenue, conversion rates, and Buy Box share.

Each sees part of the picture, but the overall view is missing.

Combining expertise

By combining our expertise at blue2purple with eTAIL agency’s operational excellence, brands can finally align these perspectives. Integrated dashboards combine advertising KPIs and retail KPIs, providing a complete view of the funnel, from media exposure to sales on Amazon or Cdiscount.

This collaboration goes further than measurement alone. It enables brands to:

• Steer investments with greater confidence.
• Identify which levers truly generate value.
• Adjust strategies with more precision.

Conclusion : digital performance as a whole

Advertising automation and marketplaces can no longer be managed separately. Each on its own delivers partial results: efficient automation disconnected from commerce, or marketplace execution isolated from media investment.

By joining forces with eTAIL agency, we demonstrate that it is possible to move beyond silos and help brands achieve a clear, integrated, and sustainable approach to digital performance.

In 2026, this integrated approach will set ambitious brands apart.
