Yahoo! JAPAN Ads Display Ads

March 11, 2026 (Wednesday)

We have changed the specifications of “Conversion value” in conversion tracking for Display Ads. Please see the next section for details.

Changes to conversion tracking settings

• For the conversion type “App,” you can now set a “Value per conversion.”

• For each conversion type, you can now set a value up to two decimal places for “Value per conversion.”

Changes to conversion tracking

• When measuring the following conversion types, decimal values in the conversion path will now also be tracked.
  
  • Web
  • Web (tracking tag)
  • App
  • Import

• When measuring conversion value, if the conversion value cannot be retrieved from requests via tracking tags or ad effectiveness measurement tools, the “Value per conversion” set when configuring conversion tracking in the Campaign Management Tool will be used. As a result, performance metrics in Performance Report/Performance Data may increase after this change is implemented.
  Note that if the conversion value is passed as “0” via tracking tags or ad effectiveness measurement tools, it will be recorded as “0.”

Changes to Performance Report/Performance Data

• In the Performance Report of the following Tools, the display format of the relevant metrics has been changed. There is no change to the display format of Performance Data.
  [Updated on March 6, 2026] Campaign Editor and Yahoo! JAPAN Ads Display Ads API have been removed from the applicable Tools. The Display Ads API is scheduled to apply this change sequentially in future versions.
