Smart Channel

Smart Channel is a premium ad placement that sits at the very top of the chat list, above the first conversation thread.

You buy it through the LINE Ads platform, and it holds the single most visible position in the app because it renders above every chat before a user scrolls. That prominence is why it costs more and why it favors awareness and event promotion over efficiency-driven direct response. You use it when you need a large audience to see one message in a short window.

A bank launching a new card runs a Smart Channel banner for a week; every time a targeted user opens LINE, the banner appears above their top conversation before they read a single message.

You are paying for position, not intent. Smart Channel guarantees eyeballs, not clicks, so plugging it into a cost-per-acquisition campaign and expecting chat-list economics will disappoint you. Treat it as a reach and recall buy with its own benchmarks, separate from your performance placements.

Top of the app costs top money.
