Yahoo! JAPAN Ads Display Ads (Auction)

Date

Ad delivery has gradually started to change from August 21, 2024 (Wednesday).

Summary

For campaign goals where the optimization point is to maximize the number of conversions, the delivery specifications are partially modified when using individual CPC.

Currently, in Display Ads (Auction), an algorithm that optimizes ad delivery according to the set Campaign goal is working.
With this change, the optimization algorithm will only be applied to eligible campaign objectives if you're using a bid strategy that automatically adjusts bids to maximize conversions. As a result, if you're using Individual CPC for target campaign goals, you won't be affected by the optimization algorithm.

<Target campaign goals>

• Conversion
• App promotion
• Item list promotion
• PayPay Gift

In light of the restricted number of cases where the optimization algorithm is applied to campaigns that use Individual CPC, we made a specification change. 
In the future, we will continue to strengthen and promote the system's optimization function for Bid strategy that automatically adjust Bids.

Impacts

Campaigns with individual CPCs and the target campaign goals will not be affected. However, campaigns that use up their daily budget may change the way your ads are served.
