Summary
We have launched the tracking tag and the new conversion API for Display Ads. At the time of launch, they are available only for Display Ads. We plan to make them available for other services in the future. Wait for further announcements with detailed schedules.
The current conversion tracking tags, site retargeting tags, and the previous version of the conversion API are still available. We recommend using the new tags and API if you are new to using conversion tracking or similar features.
Tracking tag
The tracking tag is designed to measure the performance of various LY Corporation services. You can measure user behaviors (events) by installing this tag on your website. You can use the measured event data for conversion tracking and to store audience lists of website visitors.
You can use event data measured by a single tag for multiple purposes, simplifying tag management compared to the previous format, which required separate tags for each purpose. Additionally, you can measure conversions by specifying event types.
(Note)
The conversion API is an API designed to measure and optimize ad performance more accurately. The conversion API is less affected by restrictions from enhanced browser security and ad blockers, letting you obtain more accurate tracking data.
You can use the event data measured with the new API not only for conversion tracking but also for storing audience lists of website visitors. You can obtain a more accurate measurement of advertising effectiveness by linking new parameters like "line_uid."
