How Viva and Sepiia increased conversion rates by 34% on Meta Ads with Channable’s dynamic creatives

By combining feed management with Channable’s “Creatives” feature, Viva transformed Sepiia’s static Shopify catalog into dynamic, scalable advertising experiences. Automated image optimization, enriched product data, and smarter segmentation boosted Meta Ads performance which led to a 34% increase in conversion rate.

Sepiia, a Spanish smart-fashion brand, and Viva, a performance marketing agency specialized in eCommerce, shared the same goal: scale Meta Ads revenue without raising acquisition costs. A challenging mission, especially with a constantly changing product catalog. Shopify’s native feed offered limited control over image selection, formats, and segmentation. And in fashion where your visuals drive the buying decision, this directly impacted CTR, conversions, and ROAS.

This is where Channable came in. By combining feed management with dynamic creatives through the Creatives module, Viva turned a rigid catalog into a flexible, automated, performance-driven system. The impact: +22% CTR, +34% conversion rate, –16% cost per conversion, and +27% ROAS in just seven months.

Key takeaways

• +34% conversion rate on Meta Ads
• +22% CTR and +27% ROAS after implementing dynamic creatives
• Full control over the Shopify catalog: image selection, advanced rules, and precise segmentation
• Significant time savings thanks to automated feed management

A clear starting point: well-defined Meta Ads objectives

Viva began 2025 with a clear goal: increase sales from Meta Ads while improving channel profitability. There was no fixed numerical target, but a clear direction with more efficient campaigns, stronger creatives, and data-driven decisions.

At the same time, Sepiia needed to scale paid media while maintaining visual consistency and avoiding additional manual work. With a catalog that changes constantly, achieving this level of automation was impossible with Shopify alone.

The challenges before using Channable

Before implementing Channable, the team faced three key issues:

1. Limited control over catalog images: Shopify didn’t allow selecting the ideal image for dynamic ads. Products often appeared on a plain background instead of being shown on a model which was far more compelling for fashion.
2. Difficulty adapting creatives to promotions or campaigns: Changing messages, prices, or visual layouts meant recreating images one by one.
3. Manual feed management: Cleaning and editing the catalog consumed time that could not be used for strategy, A/B testing, or scaling.

The solution: dynamic feeds and dynamic creatives

Dynamic feed management

Using Channable’s rules and filters, Viva was able to:

• Segment products by category, collection, or promotion
• Exclude items not suitable for advertising
• Prioritize images featuring models through conditional rules

With Channable Creatives, the team upgraded from basic images to full-fledged templates capable of including:

• Multiple product images (detail + model)
• Automatically inserted prices
• Dynamic promotional messages
• One-click background removal
• Consistent visual layouts without external tools

In a visually driven vertical like fashion, this creative leap had a direct impact on CTR and conversions.

Real automation

Changes in the catalog → changes in the ads.

No manual tweaks. No re-exported images. No sync issues between Shopify and Meta.

Results: a clear before and after on Meta Ads

Performance from January to July 2025 compared to the previous year:

The impact was immediate: greater relevance, better ad experiences, and a scalability level that wasn’t possible with Shopify alone.

The agency highlights that Channable’s support team played a key role throughout the process, providing expert, hands-on guidance that made implementation smoother and gave them the confidence to scale.
