Summary
In LY Ads Search Ads (Shopping), in addition to the existing conversion tag, we have started offering conversion tracking using tracking tags and server-side tracking using the Conversion API.
Using tracking tags reduces the effort required to issue and implement tags for each ad account and enables cross-product performance measurement with Display Ads and other products.
In addition, server-side tracking using the Conversion API enables you to establish a stable conversion tracking environment that is less affected by changes in browser environments.

【Key changes and new features】
● Conversion tracking using tracking tags: You can now track conversions in the Campaign Management Tool by specifying a tracking tag (a tag issued by Business Manager or an ad account).
● Use of the Conversion API: You can now issue an access token and send and track conversion data directly from the server side.
● Support for deduplication (transaction_id) and order-related tracking: Support for "transaction\_id" helps prevent duplicate tracking, while order amounts, product information, and other data enable flexible conversion tracking.
● Improved accuracy of cross-device conversion identification: Multiple identifiers are used to track conversions across different devices more accurately.
● Support for decimal values for conversion value: For the "Web (tracking tag)" conversion type, you can now set a value with up to two decimal places for "Value per conversion."
・When tracking conversions, values after the decimal point are also tracked.
・Performance reports retrieved from the Campaign Management Tool also display values with up to two decimal places.
Note that support for decimal values is currently available only in the Campaign Management Tool. Support in the Search Ads API will be introduced gradually in future versions.

Notes
● Conversion tracking using tracking tags does not support call conversion tracking.
● If you are already using snippet ID-based tracking for Display Ads or other products, separate implementation settings are required to use the same tag for snippet ID-based tracking in Search Ads (Shopping).
● If the existing conversion tracking tag and a tracking tag are placed on the same page to track the same conversion, conversions may be counted more than once. Check your settings carefully before implementation.
● The ability to create new tracking configurations using the existing conversion tracking tag is scheduled to end around fall 2026. Tracking using the existing conversion tracking tag is also scheduled to end in the future. Details, including the termination schedule, will be announced once determined.
