Date
August 26, 2025
To implement this update, we paused Shopping Search Ads delivery on the following schedule:
August 25, 2025, 10 PM JST to August 26, 2025, around 4 PM JST.
There may have been cases where some performance reports could not be retrieved. In such cases, get the reports again.
There were also temporary cases where "Conversions" related items appear with incorrect numbers in list views and other areas, but this issue has now been resolved.
Summary
We have renewed the delivery system for Shopping Search Ads in Search Ads (Shopping). By changing the system that matches search queries from internet users with product information, you can achieve more accurate ad delivery and expand features.
From July 2025, we have been running test deliveries using the renewal system for some ads. After the scheduled date, this applies to all Shopping Search Ads. As delivery trends and results may differ from those before the scheduled date, check performance reports and consider adjusting your settings and budget.
Along with the system renewal, we also changed the following features.
Conversion tracking window shortened for clicks before the renewal
Conversions from clicks that occurred before the scheduled date are tracked for a maximum of 30 days, regardless of your conversion settings. As a result, you may see a decrease in conversions.
*There is no impact on conversions from clicks occurring after the scheduled date.
End of tracking IDs
We have ended various tracking IDs used in tracking parameters and reports. The affected items and their values after discontinuation are as follows:
You can't get tracking ID information. If you use tools or reports that rely on these tracking IDs, check and consider making the necessary adjustments.
Improvements to "Gender" and "Age" performance reports and listings
Before the scheduled date, "Gender" data was only available when gender targeting was set, and "Age" data was available only when age targeting was set. After the scheduled date, you can get "Gender" and "Age" data regardless of these targeting settings.
*Data for "Age" and "Gender" from before the scheduled date appear as "Unknown" after the scheduled date.
Impression share specification changes
We have changed the method for calculating impression share when multiple products from the same account are shown. After the scheduled date, we calculate impression share based on the product with the highest auction rank.
Due to this change, values for the following items may vary after the changes:
• Impression share
• Search absolute top impression share
• Lost impression share (rank)
• Lost impression share (budget)
• Search absolute top impression rate
If you use these items in automated rules, check and adjust your conditions after the scheduled date.
End of “Search absolute top lost impression share”
After the release date, you can't get the "Search absolute top lost impression share" values from reports and various lists.
If this item was specified as a condition in automated rules, the automated rule itself has been removed.
Renaming of "Brand"
In May 2025, the "Brand" attribute in product groups was discontinued and renamed to "System Brand." After the scheduled date, it appears as "System Brand" in the Campaign Management Tool and performance reports.
The details of "Brand" and "System brand" are as follows.
Additionally, we provide a feature that allows you to use the "Brand" item in the product feed, which you input, for product group settings. We will announce further details as they become available.
Exclusion of duplicate conversions *Suspended
We have stopped offering the exclusion feature due to a system issue. The restart date is undecided.
We apologize for any inconvenience.
