To enable the highest accuracy tracking of TikTok Ads follow this guide on how to place the ThoughtMetric tracking parameter on your TikTok Ads.
ThoughtMetric TikTok Ads tracking parameter:
tmsrc=tiktokad&tmid=__CID__
To use our tracking parameters on TikTok, you will need to update the URL in the “Destination page” section of the ad settings.
Append the click-through URL parameters to your landing page URLs at the ad level.
How to handle parameters that are already in the tracking template
If you already have some tracking parameters in the destination link field, don't worry, you can use the ThoughtMetric tracking parameters in addition to any tracking you already have in place.
To use the ThoughtMetric parameters alongside your existing tracking template you will want to append our tracking parameters to the end of your existing UTM string by using a "&" symbol starting with the tmsrc parameter.
For example If you already had the following text in your tracking template:
https://mystore.com?utm_source=tiktok
You would want to append the ThoughtMetric tracking parameters so that the end result looks like this:
https://mystore.com?utm_source=tiktok&tmsrc=tiktokad&tmid=__CID__
