Thank you for using Yahoo! JAPAN Promotional Ads.
The schedule has been decided for the feature enhancement, that we
have previously announced in "Change in bid adjustment rate by device
for Sponsored Search auto bidding (Document Number: APIE-FY18-2065)".
Please see below for details.
Once again, thank you for using Yahoo! JAPAN Promotional Ads.

*The schedule may change without prior notice.
There will be a change in the range of bid adjustment rate by device
for campaigns and ad groups using auto bidding type "Target CPA".
Only "Decrease by: 100%" available
*Options other than "Decrease by: 100%" could be selected from the UI,
but the setting was invalid.
"Increase by: 0 - 900%" and "Decrease by: 1 - 90%"
*"Decrease by: 100%" will continue to be valid.
If you currently have campaigns and ad groups that are using "Target CPA"
with bid adjustment rate other than "Decrease by: 100%," ad delivery
volume may change after the effective date.
Please check and change the current bid adjustment rate by device for
campaigns and ad groups in advance if you have campaigns using "Target CPA".
If you have any questions, please contact us.
