Summary

When creating or editing advertising accounts for the applicable Products, you will be able to create and connect a Business Manager and a LINE Official Account.
This will enable smoother use of the following features and is expected to improve the convenience of services provided by LY Ads.

• Features of Display Ads
  
  • Features that require integration with a LINE Official Account (such as ads aimed at gaining friends and linking profile images of LINE Official Accounts)
  • Audience list integration feature
• Measurement tag features
• New cross-service features of LY Ads scheduled to be provided in the future

*As of the implementation date, there are no available features through connecting Search Ads accounts with a Business Manager or a LINE Official Account. Details regarding Search Ads (Shopping) will be announced once finalized.

The changes in the Campaign Management Tool related to this matter are as follows.

Changes to the Ad Account Creation and Edit Screen

On the ad account creation and edit screens in the Campaign Management Tool, a connection feature with Business Manager and LINE Official Accounts will be added.
If you apply through online sign-up, you can also newly create a Business Manager and a LINE Official Account within the same screen.
If you apply through an agency, please create them from each respective service screen.

*The above image is an example of the screen for customers applying through online sign-up. The displayed content is subject to change.

Mandatory Connection to Business Manager and LINE Official Account

If customers who applied via online sign-up create additional advertising accounts on or after the implementation date, connection to a Business Manager and a LINE Official Account will become mandatory.
However, connection to a Business Manager and a LINE Official Account will be optional in the following cases.
