Search Ads: Adding Business name assets

Product

Yahoo! JAPAN Ads Search Ads

Schedule

• Early March 2026: Start submitting Business Name Assets
• Late March 2026: Start displaying Business Name Assets

*Details will be announced once finalized. Please note that the schedule is subject to change.

Summary

A new "Business Name Asset" will be added to ad display assets for Search Ads. The Business Name Asset is a feature that allows business-related names, such as company names or service names, to be displayed at the top of ads. By increasing the visibility of service names and similar information within ads, improved advertising performance can be expected. In addition, using this asset together with favicon assets and others enables even stronger appeal.

Business Name Assets can only be associated with campaigns. Only one active Business Name Asset can be associated with a single campaign.

Notes

• After Business Name Assets begin to be displayed, ads under campaigns that do not have a Business Name Asset associated will show the domain name of the display URL (including subdomains) at the top of the ad.
  Example: If the display URL is "https://subdomain.example.com/sale/limited/", "subdomain.example.com" will be displayed at the top of the ad.
• Business Name Assets cannot be associated with campaigns whose campaign type is "App promotion".
