Why It Matters

Embedding creative testing at campaign launch ensures reliable performance data and avoids costly duplication, enabling marketers to optimize spend and improve ROI from day one.

Key Takeaways

  • Start new ads using Meta’s creative testing tool immediately.
  • Allocate full campaign budget to test, not just 20%.
  • Testing reveals ad performance under equal budget conditions early.
  • Existing ads cannot be retroactively tested without duplicating them.
  • Adjust test size, duration, and spend for statistically meaningful data.

Summary

The podcast tackles a common dilemma for marketers: whether to launch a brand‑new campaign with creative testing built in or to add testing later. Host John Lomer explains his preferred workflow, emphasizing that the creative testing tool should be applied at the moment new ads are created, not as a separate after‑thought.

Lomer recommends embedding the test directly within the active ad set that will eventually run the campaign. Although Meta suggests reserving roughly 20% of the budget for testing, he advises allocating the full budget when the campaign is brand‑new, ensuring each creative receives equal spend from day one. This approach yields early performance data and sidesteps the platform’s limitation that existing ads cannot be retroactively tested.

He highlights a painful quirk: to test an already‑running ad you must duplicate it, creating parallel ads that compete for impressions and muddy results. As an illustration, a $50‑per‑day test split across five ads (just $10 each) would generate insufficient data, prompting marketers to either test fewer creatives or extend the test period.

The takeaway for advertisers is clear—integrate creative testing at launch, allocate sufficient budget, and design tests that are statistically robust. Doing so prevents messy duplication, accelerates insight generation, and ultimately drives more efficient spend and higher ROI.

Original Description

Today's question is whether to launch a brand new campaign with creative testing or start testing later with new creatives. There's no absolute right answer, but Jon has a preferred approach with clear reasoning behind it. He explains why starting new ads with a test answers questions you'll have later, avoids the messy workaround of duplicating existing ads, and ensures you get meaningful data from the start.
