Dear customer,

Thank you for using Yahoo! JAPAN Ads.

We made some changes on Measurement feature of Yahoo! JAPAN Ads.
Please see the following details.

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


1. Product:
　Yahoo! JAPAN Ads Search Ads
　Yahoo! JAPAN Ads Display Ads

2. Effective date:
　August 27, 2020 (Thu)

3. Overview:
　Due to the recent security enhancement of browsers, we have made the
　following changes.

　■Complementary feature for conversion analytics using local storage
　　When displaying ads in some environments, conversion analytics may
　　not perform correctly.
　　To decrease this impact, we have started to supplement conversion
　　analytics using local storage.
　　"Local storage" is a data storage area and function in the browser.
　　It's a different area from cookies.

　　The duration of conversion analytics was limited to one day in some
　　environments, but now it can be extended to up to 7 days by using
　　the above function.

　　To use the conversion analytics complement using local storage, it
　　requires to add specification to the "site general tag" and
　　"complementary feature tag of conversion analytics" set on the site.

　　Following document is available fore more details on how to use.
　　"Complementary feature for Conversion Analytics Installation Guide"
　　
　　When you are not using conversion analytics, you do not need tag
　　modification.

　■Tracking reaches enhancement
　　In some environments, you can count users that previously could not
　　be captured.
　　This may increase the number of impressions and reach of your ad.
　　Please check a report and make necessary adjustments.
