Summary

Yahoo! JAPAN Ads Display Ads (Auction) increase the ad delivery of "reward format" ads, which gives users incentives that can be used on websites and apps.
Reward format was available in LINE Family apps and LINE Ads Network. We start delivering reward formats to partner sites and apps other than LYC and LYC services. This change will increase ad delivery and offer more ad delivery opportunities. We will continue to add ad places for reward formats.

Comments

The reward format will appear in full screen. The video view through rate is also high. You can expect effective ad delivery, especially for app installs and building brand awareness.
