Summary
We will launch [“portfolio bidding”] for Yahoo! JAPAN Ads Display Ads (Auction). You will be able to manage your bid strategy for multiple campaigns in bulk, reducing operational workload and improving advertising effectiveness.

• Portfolio bidding is a feature that allows you to create bid strategies at an account level and apply them to multiple campaigns. For multiple campaigns grouped into the same portfolio bidding, bids are optimized on a portfolio bidding basis. Even for campaigns that just started or have few results, relatively stable ad delivery can be expected.
  
  • By combining with the [“shared budgets,”] this enables budget allocation and bid adjustments across campaigns, increasing the possibility of achieving target values (such as conversions or ROAS).

Notes

• When using portfolio bidding, the ad delivery is controlled to achieve goals across multiple campaigns you applied. There may be differences in spend and performance between campaigns.
• You can’t use portfolio bidding for campaign goal [“app promotion.”]
• Download the latest data before using the Campaign Editor after the change date. If you update the bid strategy and bid for a campaign that has a portfolio bidding applied from an older version of the Campaign Editor, the applied portfolio bidding will be removed and overwritten as a separate bidding.

Comments
When using portfolio bidding, there are some restrictions on the features used together, such as automated rules and A/B test. Download the following document in Japanese for details.
