How merging 5 ad groups cut costs in half

How merging 5 ad groups cut costs in half

Let's talk about a tidy-up that paid off. A gadget seller had 5 ad groups, each with a tiny $10 budget.

— Each group got only a few sales, so none ever finished learning.
— First, they paused 4 and put the full $50 into one ad group.
— That single group finally hit enough results to learn properly.

In 6 days, cost per sale dropped from $18 to $9.

Why? Five small puddles of data confuse TikTok. One bigger pool teaches it fast.

The lesson: fewer, better-fed ad groups usually win.

Try this: count your ad groups, and if any have under $20 a day, consider merging them. Simpler is often stronger.
