Case Study: Mejuri Achieves Lower CPA and Higher Conversion Rates with TikTok for Business

How Mejuri Increasing holiday sales at a lower CPA using Dynamic Showcase Ads

Mejuri, a fine jewelry brand, wanted to drive more online retail sales and conversions during its biggest holiday event, Black Friday and Cyber Monday. Working with TikTok for Business, the company aimed to reach new customers in its 13–54-year-old female target audience while maintaining efficient acquisition costs during a highly competitive sales period.

TikTok for Business helped Mejuri launch Dynamic Showcase Ads (DSA) alongside In-Feed Video with Spark Ads, using Shakr to scale thousands of TikTok-native product videos and tailor ads to broad, interest-based, lookalike, and retargeting audiences. The campaign delivered strong performance, producing 49.2% lower CPA than regular In-Feed Video and a 3.2% increase in conversion rate, showing that TikTok for Business could drive efficient lower-funnel results as well as discovery.
