Beyond saturated channels: Mona Fashion’s 5.53 ROAS with Alta Solutions and Yandex Ads Space

Discover how Mona Fashion, together with Alta Solutions, diversified its performance mix and expanded ecommerce results using Yandex Ads Space, without increasing media spend or internal workload.

About the client


Mona Fashion is a leading Serbian fashion brand founded in 1989. Originating from a family business, Mona has grown into a regional market leader recognized for quality, refined style, and continuous innovation.

Over more than three decades, Mona Fashion has evolved into a modern retail and ecommerce company, combining established craftsmanship with a customer-focused digital approach. Ecommerce today plays an important role in the brand’s overall growth strategy alongside its retail network.

About the agency


Alta Solutions is an ecommerce and performance marketing company supporting merchants across all stages of online growth. The agency focuses on building, optimizing, and scaling ecommerce businesses through data-driven performance marketing, analytics, automation, and user experience improvements.

Alta Solutions works across the full ecommerce ecosystem, covering advertising, technology, growth strategy, and profitability with a strong focus on practical, data-backed outcomes.

Challenge

Before adopting Yandex Ads Space, Mona Fashion’s performance marketing relied mainly on Google Ads and Meta Ads. While these platforms continued to deliver volume, rising competition led to higher acquisition costs and limited scalability at higher spend levels.

Like many established ecommerce brands, Mona Fashion faced several challenges:

  • Dependence on a small number of highly competitive channels
  • Increasing CPAs and decreasing marginal returns
  • Limited room for growth within the existing media budget

The objective was to broaden traffic and revenue sources, support ecommerce growth, and improve overall channel efficiency, without adding operational complexity for the internal team.

“When a brand reaches a certain level of maturity, scaling becomes less about volume and more about structure. For Mona Fashion, the task was to introduce an additional channel that fit naturally into the existing setup and could be managed with the same performance discipline as the rest of the media mix.”

Solution

Alta Solutions added Yandex Ads Space to Mona Fashion’s existing media mix as an additional performance channel. Instead of increasing total spend, part of the budget was reallocated to reach new audiences and reduce reliance on highly competitive platforms.

How it worked

  • Complementary role: Yandex Ads Spacesupported existing campaigns, focusing on expanding reach rather than replacing current activity.
  • Audience-based reach: The platform enabled engagement beyond traditional search environments, helping capture demand at scale.
  • Performance management: Campaigns were optimized against defined ROAS and CPA targets to ensure stable results over time.
  • End-to-end execution: Alta Solutions managed setup, optimization, and ongoing operations, requiring no additional effort from Mona Fashion’s internal team.

This approach helped Mona Fashion improve channel balance while keeping costs and performance under control.
