Case Study: Joom Marketplace

How We Achieved Over 400k eCommerce App Installs with TikTok Value Optimisation


400k+ installs
14k+ purchases

Joom Marketplace helps consumers make shopping easy and entertaining, giving access to high quality goods from around the world. The brand was looking to capitalise on the buying potential of new users through their campaigns, as well as find a new way to reach engaged audiences. For the past years, Joom has been trying different ways but unfortunately all methods weren’t quite effective. The client approached our team in March, 2021 to work out the same challenge and hoped to leverage deep funnel solutions to reignite solvent customers and increase sales.

Conversion Rate to purchase 10%



Our main objective was newly launched items sales, with different in-app event optimisation targets, such as installs, add-to-cart buttons or in-app purchases.

In partnership with Joom, we ran in-feed auction ads as the central solution, with a core focus of re-engaging audiences. The brand made multiple value based optimisation (VBO) campaigns across various regions, and the ads were optimised towards ROAS. The approach was always-on, cost efficient, and featured creative that felt native to their key audiences who had already shown an affinity for Joom products. Besides, authentic and ownable short videos, optimized for a target consumer, were incredibly funny, and above all, demonstrated product use and raised awareness for different categories (especially, clothing and accessories).

User Acquisition

The creatives included strong native TikTok elements such as text overlay, an intro within the first 3 seconds, text-to-speech, and trending sounds from the GML. Our team leveraged these organic videos as Spark ads and ran in-feed campaigns aiming to deliver a strong ROAS while maximizing conversions. We highlighted the most selling products along with the message: «Joom – buy with pleasure!», while targeting predominantly female audiences ages 18-55+. Due to TikTok unique algorithm, we were able to catch the right users with the right products, grabbing their attention and connecting them in a way they hadn’t been able to achieve on other platforms.

AdChampagne team localised creatives in ten different languages, which gave an authentic feel to ads and appealed to a wider range of local target audiences. The brand built confidence and trust with consumers by putting a unique twist on their repurposed organic videos. The content demonstrated the type of products available through the Joom website and used TikTok’s in-app editing tools to overlay text and voiceover to highlight the quality of their offerings.

Our Approach with TikTok Ads

Part of the strategy implemented to achieve this business goal involved using a robust TikTok Ads campaign. We took a series of well-planned steps as outlined below.

Due to the close-knit teamwork our team managed to create, adapt and test dozens of videos. We use three main formats with an eye on building trust, raising brand’s credibility, and increasing customers loyalty (as well as different videos for retargeting):

The test lasted two month and gathered enough users to achieve statistical significance and confirm our hypothesis – Joom’s installs grew by 112 %.


In just a few months, Joom drove more than 400k installs working with AdChampagne. Combining VBO and App Event Optimisation strategies produced great results with over 14,000 purchases made off the back of the In-Feed Ad campaign.
