Time to Conversion

Introduction

Standard ad metrics tell you if a customer bought, but they rarely tell you when. The Time to Conversion model measures the true consideration period—tracking the exact delay between a trigger event (like an ad impression, a search, or a first purchase) and the final transaction or Subscribe & Save (SnS) signup.

By understanding your shoppers' natural decision cycles, you can set realistic KPIs and adjust your media pacing so your retargeting hits exactly when the customer is ready to buy.

Use this data to answer:

• After seeing an ad, how long does it actually take for a user to buy or subscribe?

• How does the consideration period differ between high-ticket items and quick impulse buys?

• Are shoppers who search for specific keywords buying immediately, or browsing for weeks?

• How long does it take for a New-to-Brand (NTB) buyer to make their second purchase or commit to a subscription?

When to Use This Report

Pull this report when you need to eliminate the guesswork from your retargeting strategies and justify your lookback windows to clients or leadership:

• Optimize Retargeting Budgets: See exactly when your shoppers convert to evaluate your current lookback settings. If 90% of your conversions happen within the first 3 days, this report clearly outlines your peak consideration window versus the long tail. It provides the exact behavioral timeline, giving you the data needed to decide how you want to structure and define your retargeting audiences.

• Plan Product-Specific Strategies: Prove to stakeholders why high-priced goods need longer consideration periods than cheap consumables, and set accurate, product-level expectations.

• Evaluate Keyword Urgency: Identify which search terms signal an immediate intent to buy versus early-stage research.

• Forecast Subscription & Loyalty: Map the exact timeline needed to turn a first-time buyer into a recurring revenue stream.

How to Use It

The dashboard uses a top toggle to split data into two primary views: Purchase Event and Subscribe & Save Event. Choose your goal to track the delay leading up to a standard one-off order or a recurring SnS signup.

Both views feature a comprehensive data card (showing the Peak Conversion Time, Average Time, and the time it takes for 90% of users to convert) alongside a dual-axis chart:

• The Bar Chart: Shows the exact number of users who converted within a specific time slot (helps identify your absolute Peak conversion window).
• The Line Chart: Shows the Cumulative Percentage of users who have converted (helps you see exactly when you hit the 80% or 90% threshold to cut off retargeting).

Strategic Scenarios

Use the table below to set up specific queries based on your strategic goals:

 

Goal & Trigger Event	How to Set Up	What to Look For	Strategic Action
Media Retargeting Strategy (First Ad exposure -> Purchase/SnS)	Group your campaigns by ad type (DSP, SP, SD, SB) to analyze the performance of each channel.	The time slot where the line chart hits 80-90% cumulative conversion.	Compare this exact time frame against your current DSP and Sponsored Display retargeting lookback windows to evaluate if your audience settings align with actual conversion behavior.
Loyalty & Retention Timing (NTB Purchase -> Repeat/SnS)	Toggle to the SnS or Purchase tab and select the NTB sub-tab.	The average delay between a shopper's first-ever brand purchase and their second order/subscription.	Time your post-purchase lifecycle emails or DSP loyalty retargeting campaigns to hit the shopper right as they enter this peak re-order window.
Cart Abandonment Recovery (Add to Cart -> Purchase/SnS)	Requires Custom Model. Filter by specific ASINs.	The average time delay between carting and checking out for high-value items.	Launch highly aggressive, short-term retargeting tactics specifically designed to close the gap on abandoned carts.
Listing Effectiveness (Detail Page View -> Purchase/SnS)	Requires Custom Model. Filter by specific ASINs.	Products with a very long consideration period after a page view.	A long delay here suggests the buyer is hesitating. Improve A+ content, address negative reviews, or add comparison charts to speed up the decision.
Keyword Intent & Bidding (Search -> Purchase/SnS)	Requires Custom Model. Enter specific keywords.	Search terms that yield an immediate, short-term conversion spike on the bar chart.	Increase your Top-of-Search bids for these high-urgency keywords to capture immediate demand.

FAQ

Q: Can I run this report for a short timeframe, like a single week?

A: No, the minimum date range is 30 days. Because this model measures the time it takes for someone to finally buy, it requires a longer window to accurately capture the full decision-making process.

Q: How does the "Time Grouping" feature work?

A: This setting lets you choose how the timeframes are broken down on your chart. When building a custom model, you have two options:

• Fixed Interval: The system automatically slices your total date range into equal, even chunks of time.
• Custom Event Grouping: You manually define the exact time buckets you want to see (e.g., 0-1 days, 2-3 days, 4-7 days) to perfectly match your reporting needs.

Q: Does this model only track ad traffic, or can it track organic traffic too?

A: It tracks both. If you have Amazon Purchase Data Insights (FSI) enabled, you can measure the exact consideration period for organic Detail Page Views, Searches, and Cart additions—including organic Subscribe & Save signups.
