How long does it take for a customer to make a purchase after seeing your ad?

Many Amazon advertisers follow the common rule of waiting 7–14 days before adjusting bids or budgets, assuming that’s when most conversions occur.

Now, with Amazon Marketing Cloud (AMC), you can move from assumptions to accurate insights.

AMC’s time-to-conversion report enables you to measure exactly how long it takes for a customer to convert after engaging with your ads.

In some FMCG categories, over 50% of purchases happen within just 10 minutes of viewing an ad. In others, nearly 80% of orders are placed within 7 days.

The time-to-conversion also varies based on the type of campaign. Sponsored Products often drive faster conversions compared to DSP or Sponsored Display.

Understanding these timelines helps you plan budgets, promotions, and bidding strategies more effectively.

Whether it’s for a single campaign, an entire product category, or your full catalog, AMC gives you the flexibility to analyze conversion windows with great precision.

You can even compare how different days, such as weekends vs. weekdays, impact purchase behavior and optimize your campaigns accordingly.

With AMC, you can break down data by ASIN, category, or campaign type, and make informed decisions based on when your customers are most likely to buy.

One key detail: If a shopper sees your ads multiple times, AMC calculates the time to conversion from the last exposure before purchase.

Understanding these patterns allows you to move beyond the standard 14-day attribution model and tailor your approach based on actual customer behavior.
