Question

Conversions spike using a 24-hour window but drop dramatically with a 1-hour window. How should I choose the right window length for my campaign goals?

Answer 1

Great observation, and this is a super important question for tracking performance accurately!

What the Window Length Really Means:

• 1-hour conversion window shows immediate actions after someone clicks your ad — good for fast purchase decisions (like flash sales).

• 24-hour window captures delayed conversions — people who click, think, and come back later to buy.

How to Choose Based on Campaign Goals:

If You’re Running Time-Sensitive or Impulse Offers

Use 1-hour window if your goal is:

• Quick actions (e.g., sign-ups, low-cost impulse buys)

• You want to optimize for real-time response

If You’re Selling Considered Purchases or Higher-Ticket Items

Use 24-hour (or even 7-day) window if:

• Your audience needs time to research or decide

• You want a fuller picture of attribution

Pro Tip:

Use both in reporting:
Compare short vs. long windows to understand how long your buyers take to convert — it’s a great insight for refining retargeting and funnel timing.

If your campaign goal is speed and immediacy, the 1-hour window helps. If you want a more complete view of your results, stick with the 24-hour window. Most businesses benefit from optimizing around the 24-hour view, unless you're doing high-frequency, rapid-fire offers.
