LINE Audience

A LINE Audience is a custom audience you build from your own data to target or exclude specific users in the LINE Ads platform.

You create it from sources like website visitors captured by the LINE Tag, uploaded phone numbers or emails, app events, or friends of your Official Account. Once built, you point campaigns at it for retargeting or use it as an exclusion so you stop paying to reach people who already converted. It is also the seed you feed into a similar audience when you want to expand.

An e-commerce store uploads the phone numbers of customers who bought in the last ninety days, builds a LINE Audience, and excludes it from a prospecting campaign so budget goes only to new users.

Match rate decides everything. A list that maps poorly to LINE accounts shrinks to a fraction of what you uploaded, and audiences below the minimum threshold will not serve at all. Check the matched size after upload, not the row count of your file, before you plan spend around it.

Your data, matched to real accounts. Verify the match.
