For fashion retailers, a mobile app is more than just another sales channel — it’s a familiar and convenient way to engage with their audience. However, even a strong brand can remain invisible without effective ASO.

In this case study, we share how we helped a multi-brand clothing and footwear retailer enhance its app visibility, nearly double organic installs, and raise its rating from 3.6 to 4.9 through optimization, seasonal campaigns, and targeted user communication.

About Our Partner

A multi-brand retailer of clothing, footwear, and accessories with both online and offline operations.

Cooperation Goals

The company has long been established in the Ukrainian market, but its mobile app had not reached the expected level of popularity. Since mobile apps are a key channel for fashion retailers, the partner chose to focus on promoting it in the App Store and Google Play.

Our goals:

  • Increase visibility in search results
  • Drive more app installs
  • Improve user ratings

Team Actions

We divided the work into several key steps to address everything from keyword optimization to performance evaluation and ratings:

  1. Competitor analysis and semantics collection
  2. Metadata optimization
  3. Results evaluation and new iterations
  4. App Rating Prompts strategy
  5. Seasonal communication

Step 1. Competitor Analysis and Semantics Collection

At the first stage, we identified relevant keywords ключевые слова and assessed their popularity. We also analyzed how competitors approach text optimization, focusing on three groups:

  • Ukrainian clothing, footwear, and accessory retailers.
  • Large marketplaces with a wide assortment of goods.
  • Foreign platforms popular among Ukrainians (e.g., Allegro, eobuwie.pl). Since 2022, these brand names have increasingly appeared in search terms in Ukraine.

Step 2. Metadata Optimization

Next, we prepared metadata for three locales indexed in Ukraine: English (UK), Ukrainian, and Russian, applying a tailored approach for each site.

In the App Store:

  • We placed the most popular and relevant keywords in the Title field.
  • We added keyword combinations that reinforce the Title in the Subtitle and Keywords fields.
  • We included competitor brand names and other target terms from the semantic core in the Keywords field.

In the Google Play:

  • We selected up to five phrases that accurately reflect the essence of the app.
  • We updated the App Name, Short Description, and Full Description, maintaining the required keyword density (three to five repetitions).
  • We used Google Natural Language to ensure the description was correctly identified as a Shopping category, achieving a Confidence score above 0.9

Step 3. Results Evaluation and New Iterations

In the App Store, we regularly updated metadata (once or twice a month) to test different combinations. We kept the ones that consistently placed the app in the top 10; as for those that turned out to be ineffective, we decided to replace them.

In Google Play, we set up Custom Store Listings for branded keywords and updated the description to target a broader range of search terms.

Step 4. App Rating Prompts Strategy

We proposed options for placing rating prompts in the app, taking two key factors into account:

  • Unobtrusiveness: It’s important not to overwhelm users with unnecessary push notifications.
  • Timing: The prompt should appear when users are most likely satisfied, for example, immediately after successfully placing an order.

Step 5. Seasonal Communication

Throughout the year, we adapted metadata and Custom Store Listings to align with seasonal events in the niche — from back-to-school and Halloween to Black Friday. This approach helped maintain relevance and reinforced the app’s position in search results.

Read how new screenshots and descriptions on Google Play increased conversion by +12.8% — COMFY Case Study.
