INTRODUCTION

Kal-tsa is a well-established Greek e-commerce brand specializing in socks, underwear, and related everyday essentials. With a strong market presence and a clear value proposition centered on quality and reliability, the brand has cemented its position as a leading destination in its sector.

THE CHALLENGE

The challenge

The objective was clear yet demanding: To optimize ad budget efficiency at the product level, without increasing spend and without relying on external interventions (such as site redesigns or changes). Success had to be driven exclusively through performance strategy and media optimization.

The challenge was twofold:

  • High industry competition.

  • A demanding, price-conscious audience.

KPI Objectives

  • Increase ROAS

  • Improve Conversion Rate

  • Acquire higher quality traffic

  • Enhance Brand Recognition

  • Scale sales without increasing budget

Services

  • Google Ads
  • Meta Ads

THE SOLUTION

The method

The approach was based on full-funnel performance marketing, leveraging a unified combination of Google & Meta Ads, with Video Creative as the central pillar.

Why Video? Video functioned as:

  • A primary conversion driver in the lower funnel.

  • A medium for product education (use cases, quality, differentiation).

  • A signal amplifier for Google & Meta’s algorithmic systems.

  • A brand & performance bridge, especially in Advantage+ and PMax environments.

The implementation relied on a full-funnel performance strategy, with clear roles per channel and the use of Video as a central performance lever.

Google Ads

  • Performance Max (1 campaign for the entire product catalog):

    • Asset-level segmentation and distinct asset groups per key category.

    • Feed mapping for better product understanding by the system.

    • Integration of video assets, boosting coverage on YouTube, Discover & Gmail and improving conversion signals.

  • Search Campaign – Brand: For brand traffic protection, CPC control, and maximizing conversion rate.

  • Search Campaigns per key category: Aligned with the e-shop structure.

  • Utilization of audience & keyword insights: For continuous optimization and ROAS improvement across the funnel.

Meta Ads

  • Advantage+ Shopping Campaigns: With full product coverage and a video-first approach.

  • Sale campaigns per key product category: Aiming for immediate commercial performance during promotional periods.

  • Video creatives adapted per funnel stage:

    • Prospecting

    • Engagement

    • Dynamic Remarketing

  • Layered remarketing funnels based on:

    • Video engagement

    • Add-to-cart & on-site behavior

  • Utilization of email lists: For sales-driven campaigns and the reactivation of existing customers.

Video creatives, combined with category-based sales campaigns, acted as a key performance accelerator, significantly increasing conversion efficiency, reducing cost per conversion, and substantially boosting ROAS.
