TikTok is seeking to assist marketers to continue to monitor engagement data, despite the gradual phase-out of cookie tracking, through a new partnership with Dentsu, which will offer alternative web tracking through Dentsu's 'Digital X' process.
The new process will allow advertisers to track user data through the TikTok Events API, which will be integrated into X-Stack.

According to TikTok:

"Dentsu Digital's X-Stack Connect is a server-side measurement platform that assists advertisers in measuring online behavior on websites using server access logs with user consent. Profiles can be built around actions such as website visits, logins, and form entry information."

This basically means the integration will provide better response tracking to gauge the efficiency of your TikTok campaigns even as the cookie tracking is phased out.

All social platforms are working to provide alternative tracking solutions to ensure that campaign performance measurement can continue to exist despite increasing restrictions on data flow. Meta says it has lost billions with Apple's iOS 14 update and users increasingly opting out of data tracking, and with Google also looking to scale back tracking on the web, the measurement landscape is becoming increasingly restrictive.

Some are now looking towards increased automation for the maximal performance of advertisements, whereas third-party providers such as Dentsu now work with alternative solutions in a manner that enables integrated data tracking within privacy-friendly constraints.

Eventually, groups of such websites will join forces and yield much more comprehensive sets of allowable user data and virtually replace the systems being currently used and enable better tracking. But until then, alternative means will be solely dependent on using various available alternatives, such as in the example above, for improving control over response.
