Yahoo! JAPAN Ads Display Ads (Auction)

December 15, 2025

We have released a simulation feature for Display Ads (Auction) that predicts the audience (users) available for ad delivery.
This feature shows the predicted audience size based on your targeting settings.

• Bulk creation view (from campaign to ad)
• Ad group creation view
• Ad group modification view

• All campaign goals (excluding PayPay Gift)

• The predicted audience size will not be shown in the following cases:
  • When the placement list contains 1,000 or more URLs (including both delivery and exclusion)
  • When radius targeting is specified
• Smart targeting settings are not reflected in the predicted values.
• Delivery to Yahoo! JAPAN and LINE partner networks is not included in the prediction.
• The audience size may include duplicate users due to factors such as sign-in status or multiple device usage, and may not match the actual number of unique users.
