No, you can’t use the same remarketing tag across different platforms like Google Ads, Meta Ads, LinkedIn, or TikTok. Each platform requires its own unique tag or pixel that is designed to track user behavior in a way that their system can understand and optimize.
For example, Google Ads uses the global site tag (gtag.js), Meta uses the Facebook Pixel, LinkedIn uses the Insight Tag, and TikTok has its own pixel as well. These tags are not interchangeable because they send data in different formats and to different endpoints.
If you try to use the same tag for multiple platforms, you risk breaking the tracking or collecting incomplete data. This can lead to inaccurate audience lists, poor optimization, and wasted ad spend.
What you should do instead:
Install each platform's remarketing tag separately. You can manage them all through Google Tag Manager to keep things organized. Also, make sure your cookie banner or consent system allows users to opt in to each tag appropriately.
So while you can remarket across platforms, you need to do it with separate tags for each.
