The status shows "Ad Review Failed." What should I do?

Platforms like Google and Yahoo review submitted ads based on their own criteria,

to ensure that the ad content and the linked site are appropriate,

and ads cannot be published unless they pass this review.

Even after passing the initial review, periodic re-evaluations are conducted,

and there are cases where ads may suddenly fail the review.

If an ad fails the review, you can check the detailed reasons for the failure from the Yahoo or Google management screen,

review the content, and resubmit the corrected ad or destination URL from Shirofune for re-evaluation.
