Dear customer,

Thank you for using Yahoo! Ads.

There will be an enhancement made to Performance data and reports for
Display Ads. Please see the following details.

Once again, thank you for using Yahoo! Ads.

1. Product:
　Display Ads

2. Schedule:
　February 19, 2020 (Wed)
　*Schedule may change without prior notice.

3. Overview:
　The counting method for the actual conversions will change for
　Performance data and reports of Display Ads.
　
　[Before]
　　Conversions occurred on the same day as the click was counted as
　　today's conversion.
　　*Conversions occurred on the day after the click was not counted
　　on the day the conversion occurred.
　　
　　Example:
　　The ad was clicked on February 9 and its conversion occurred on
　　February 10 can't be checked until February 11.
　　The conversion is counted as occurred on February 9.
　　
　[After]
　　Today's click and past click are both counted as a conversion of
　　the day.
　　*Conversions occurred on the day after the click will be counted
　　on the day the conversion occurred.
　　
　　Example:
　　The ad was clicked on February 9 and its conversion occurred on
　　February 10 will be counted on February 10.
　　The conversion is counted as occurred on February 9.
　　
　Before the change, for conversions that occurred other than the
　same day as the click, there are some cases where less number of
　actual conversions is reported than actual.
　With the new method, more accurate conversions will be available.

4. YDN API:
　Impacts on YDN API are as follows.

　4-1. Impacts:
　　- Performance data which can be acquired with StatsService
　　- Performance data which can be acquired with ReportDefinitionService

　4-2. Effected version:

5. Remarks:
　- Conversions is counted up as actual data on the day when user
　　click occurred.

　　including "All Conv." and "All Conv. Rate".
