When it comes to scaling without breaking performance, the key is to avoid triggering the learning phase and maintain delivery stability. Here's how pros typically approach it:
1. The 20% Rule (Still Works, But Slowly)
You can safely increase the budget by 10–20% every 3–4 days.
This method avoids resetting the learning phase and is ideal for preserving algorithm learnings.
Downside? It’s slow, especially if you're trying to double or triple spend.
2. Duplication Strategy (Controlled Scaling)
Another smart method is to duplicate the ad set and scale the duplicate with a higher budget.
Why it works:
Pro tip: If you're duplicating, don't change the audience or creative drastically — otherwise, it’ll hit the learning phase again.
3. Use CBO (Only If Already Structured That Way)
Switching to CBO mid-way can reset learning if your ad sets aren’t well balanced.
However, if you're already using CBO and it’s working, you can scale by increasing the campaign-level budget by up to 20–30%.
Don’t move a stable ABO campaign into CBO just to scale — it's risky.
4. Breakout Scaling (Advanced)
If you're confident and have tracking dialed in:
Create a new campaign with the same winning ad set.
Use a larger budget, possibly 2x–3x your original.
Let it run side-by-side while the original keeps performing.
This is how many big-budget advertisers scale fast while hedging risk.
5. Monitor ROAS & Frequency
As you scale, watch for rising frequency and declining ROAS.
Even good creatives fatigue, so consider rotating in fresh creatives as you increase spend.
