To measure the effectiveness of your ads on LINE Ad Manager, you need to insert LINE tags on the pages you want to track. LINE tags consist of three codes: base codes, conversion codes, and custom event codes.
To get a LINE tag from LINE Ad Manager:
1. From the top page, click the Ad accounts tab > the ad account you want to track.
2. Click the menu icon at the top left of the ad manager screen > Tracking (LINE tag) under Shared library.
3. Check the codes.
Insert the codes that you need on the advertiser's site based on what you want to track. For information on how to insert tags, see the following Help articles:

See below for more information on the Tracking (LINE tag) screen:
Status
The tag status contains the following information:
• Name: The name of the tag. For event codes, the name you set will appear once the tag starts working.
• Status: Shows if the tag is currently "Active" or "Inactive." A tag will appear as Active if it was inserted correctly and is working with no issues. If a tag hasn't worked for seven days, it will show up as Inactive.
• Last contact: The last date the tag was called on.
Base code, Customer event code, and Conversion code
Copy the codes that you need and add them to a web page.
Custom audience
Follow the link to create custom audiences, including audiences for retargeting and lookalike audiences. LINE tags can be used to accumulate visitor data, which can be used to deliver ads for retargeting.
Tracking method
If you can't use third-party cookies, you can use first-party cookies and local storage for tracking.
Important:
- If you inserted a tag but the status shows up as Inactive, check again to make sure it was inserted correctly.
- For cross-domain tracking using first-party cookies, you need to make adjustments to the base code. For more information, see
this Help article.
