The optimal Ad Network mix can serve up user acquisition acceleration. It’s how Temu doubled its month-over-month (MoM) growth rate in its third month from launch. It’s also how Sephora broke through its growth plateau and grew 61% quarter-over-quarter (QoQ) in Q4 –  its highest QoQ increase in 5 years.

The ad intelligence on Temu and Sephora in Q4 show us easy-to-follow experimentation. While Mixed Media Modeling is an excellent process for automating advertising optimization, when you need clear answers, you don’t want to over-complicate the equation. 

Here’s what Sephora’s simple experiment looked like in Q4:

1. Finding out what ad network top-performing competitor Ulta used.

2. Turning off campaigns and creatives with the one ad network that had run its top-performing ads for years.

3. Reallocating spend to the new ad network to run a simple creative.

The 61% jump leapfrogged Ulta’s 40% growth during the busy holiday shopping season. What’s more is that Sephora had sequential monthly active user (MAU) growth at its highest QoQ growth rates when it made the switch: +25% QoQ in Q4 and +35% QoQ in Q1 2023.

This indicates stronger funnel stage conversion from the ads.

Despite its infamously high budget, Temu takes a similar approach. Taking a focused approach, Temu placed only a few ad network bets each month with the same basic creative.
