Starting from Q1 2026, we are making ads performance reporting more insightful to help you truly understand the impact of your ads.

With this enhancement, ads will continue to use 7‑day click attribution, while introducing a new 1‑day view attribution (for GMV Max Product campaigns) and impression‑based delivery.

These upgrades ensure your ads are recognized not only for clicks, but also for the visibility and engagement they create — helping you better understand your ads' true impact.

Together, these changes make your ad reports more accurate, transparent, and performance‑driven, so you can optimize confidently and grow your sales effectively.

Upcoming Changes

Why This Matters

1. Reach more potential buyers: Your GMV Max Product campaigns can now be credited for influencing buyers who see your product and purchase shortly after — not just those who click. This helps you capture the real value of every impression.
2. Make every impression count: With impression-based delivery, your ads are optimized to reach audiences more effectively and get measured for actual visibility and awareness impact.
3. Gain richer, actionable insights: Understand how buyers engage with your ads from the first view to the final purchase and use those insights to improve future campaigns.
4. Fairer performance measurement: Your ad results now reflect how your campaigns drive conversions, ensuring your budget works harder and smarter for every buyer interaction.

Understanding NEW 7-Day Click and 1-Day View Order Attribution

Click Attribution

1. A buyer clicks on Product A's GMV Max campaign and places an order for 2 units of Product A and 1 unit of Product B from the same shop within 7 days.
2. Result: Both Product A and B sales will be attributed to Product A's campaign.

View Attribution (New: GMV Max Product campaigns only)

1. A buyer views Product  A with an active GMV  Max Product campaign and places an order for 2 units of Product  A and 1 unit of Product B from the same shop within 1 day.
2. Result: The total sales of Product A will be attributed to Product A’s GMV Max  Product campaign. Sales of Product B is not attributed to the campaign because 1-day view attribution only covers promoted products.

Understanding NEW Impression-based Delivery

1. Seeing the same ad multiple times in the same placement (e.g., Search results)

1. If a buyer sees the same product ad within 24 hours in the same position, it counts as one impression.
2. If the same ad appears in a different position within the same placement, it will count as another impression.
3. Example:
4. Ad A shown twice in the same Search position within 24 hours → 1 impression.
5. Ad A shown in two different Search positions within 24 hours → 2 impressions.

 2. Seeing the same ad in different placements (e.g., Search and “You May Also Like”)

1. Each placement is tracked separately.
2. If your ad appears in multiple placements, it will count as one impression per placement, even if seen within the same session.
3. Example: One impression in Search + one impression in “You May Also Like”.

3. Viewing the ad again after closing and reopening the app

1. Each new session restarts impression tracking.
2. If a buyer closes and reopens the app, seeing the same ad again will count as a new impression.

4. Viewing less than half of the ad area

1. If less than 50% of your ad is visible on screen, it won’t be counted as an impression.
2. This ensures impressions only reflect meaningful visibility.

5. Scrolling past an ad quickly

1. As long as the entire ad is visible (100% in view on screen), it will be counted as an impression, even if the viewer scrolls past it in less than one second.
2. Impressions depend on visibility, not on time spent viewing the ad

Key Takeaways

1. 7‑day click attribution stays the same, with no seller action needed.
2. 1‑day view attribution has been added for GMV Max Product campaigns.
3. Impression-based delivery provides fairer ad performance by using impression data.
4. You will see the new metrics directly reflected in your Ads Dashboard once the update goes live.

Frequently Asked Questions

Will this affect how I am charged for ads?

1. Yes. Under impression‑based delivery, ads are charged based on impressions (views) rather than clicks.

What is changing in conversion tracking?

1. Click attribution (7 days): no change; applies to all campaigns.
2. View attribution (1 day): newly added for GMV Max Product campaigns, attributing orders made 1-day after a buyer views the ad and purchases the promoted product.

Do I need to do anything?

1. No, no action is required.
2. You will receive an in‑platform notification once the updates take effect, and your ad reports will automatically reflect the new metrics.
