Our home page shows these on one card. They were two separate projects, so we list them separately here.
01
Project A: LINE Ads for an international airline
•Client: International airline (name withheld)
•Channel: LINE Ads (video)
•Goal: Awareness and engagement
•Period: 4 months
•Ad spend: ¥30M
| Metric | Result |
|---|---|
| Impressions | 2.6B |
| Video views | 45M |
| Cost per view | ¥0.67 |
| Clicks | 900K |
| Cost per click | ¥33 |
Cost per view is ad spend divided by video views (¥30M ÷ 45M). Cost per click is ad spend divided by clicks (¥30M ÷ 900K).
02
Project B: LINE Official Account for UND Ventures
•Client: UND Ventures (sleep-improvement device)
•Channels: Meta Ads, landing page, LINE Official Account, L Message
•Period: about 4 months
The challenge
Promotions on LINE were one-off sends. There was no follow-up and no nurturing after someone added the account.
What we did
✓Built the route from Meta Ads to a landing page to LINE registration.
✓Sent educational content and coupons, split by segment.
✓Set up step messages, segments and a rich menu.
✓Sent messages tied to the crowdfunding launch.
