Product

Yahoo! JAPAN Ads Search Ads

Schedule

We will start to apply it in stages from January 2025 and will be complete by the end of January.
*This date is subject to change.

Summary

To improve ad relevance, we will review the metrics used to calculate auction rank factors of Yahoo! JAPAN Ads Search Ads.
Note that this change may result in changes to various figures in your account, such as the number of clicks, the click rate, and the lost impression share.
Check the different figures in the report, as the nature of the fluctuations will vary depending on how the account is set up.
In addition, we will disclose the factors that are important or have no impact on improving ad quality, rather than the factors that determine "ad quality."

The factors are as follows:
