Dear customer,

Thank you for using Yahoo! JAPAN Ads.

We will change some calculations on reporting items related to impression
share of Search Ads. Please see the following details.

Once again, thank you for using Yahoo! JAPAN Ads.


1. Product:
　Search Ads

2. Schedule:
　Sequentially released from October 21 to November 5, 2020.

3. Overview:
　The data used for calculations of the following reporting items will
　change. Currently, in addition to search sites, we are calculating the
　value based on data such as image search, in-site search, and ad
　display according to the keywords displayed on the site.
　
　After the effective date, the value of the reporting items will be
　calculated based only on the data of the ad displayed on the search site.
　Therefore, the value of reporting items may change after the effective
　date.

　[Reporting items to be changed]
　- Exact Match Impression Share
　- Search absolute top impression rate
　- Search top impression rate
　- Impression Share
　- Search top impression share
　- Search absolute top impression share
　- Budget Lost Impression Share
　- Search lost top impression share (budget)
　- Search lost absolute top impression share (budget)
　- Lost Impression Rate (Position)
　- Search lost top impression share (rank)
　- Search lost absolute top impression share (rank)

4. Note:
　When you create a performance report (or check the performance data
　of the Campaign Management Tool) after the effective date, the data
　values on past dates will also be changed to the values calculated
　based on the new specifications.
　Therefore, you need to get performance reports before the effective
　date if you want to check the data values calculated based on the
　current specifications.
　
　
If you have any questions, please contact us.

Sincerely,
Yahoo! JAPAN API support team
