Removal of some items in the audience list creation and editing view

■Schedule
May 28, 2025
*This date is subject to change.

■Summary
We will remove the following items from "Rule" in the audience list creation and editing view for "App users" to simplify the views in the Campaign Management Tool.

• Custom label
• Page type

If there are any audience lists with these items set, change the settings based on the parameters (such as event types) associated on the advertiser's side by the scheduled date. Removing the rule items doesn't affect ad delivery for the app user audience lists.

Enhancements in tracking parameters and data connection to tracking tools

■Schedule
June 4, 2025
*This date is subject to change.

■Summary
(1) Expansion of tracking parameter usage
The following tracking parameters, previously available only for the "App promotion" campaign goal, will now be available for all campaign goals.

• {ci}
• {deviceAppType}

This change allows for more varied tracking across campaigns with goals other than "App promotion."

<Notes>
When you track conversions for campaigns with goals other than "App promotion," specify the link ID created in the Display Ads account in your tracking tools (Adjust, AppsFlyer, Kochava, Singular). If you don't specify the link ID, conversion tracking won't work correctly.
Learn more about Connect ad measurement tool and Display Ads account.

(2) Data connection to tracking tools through the conversion tracking complementary feature
If the account's auto-tagging setting is "Set," the "_p_c" parameter is added to the ad URL and linked as a click identifier to tracking tools(*) associated with Display Ads. By linking click identifiers that lead to app conversions to tracking tools, you can expect an increase in conversion tracking rates. *In AppsFlyer, you can't use the "_p_c" parameter for conversion tracking.
