Setting up your UTM parameters correctly is ESSENTIAL for accurate attribution with Cometly. If any of your ads are not set up correctly then Cometly will not be able to track a portion of your sales (i.e. Cometly will not track any purchases from an ad if it does not have the correct UTM set up). If you follow the instructions below, your UTM setup will be perfect for tracking your TikTok ads with Cometly.

Cometly needs 1 of the the 5 following UTM parameter codes attached to the end of every Website URL in the "Destination page" section of each of your TikTok ads:

  • ?utm_source=tiktok&utm_campaign=__CID__

  • ?utm_source=tiktok&utm_medium=__CID__

  • ?utm_source=tiktok&utm_term=__CID__

  • ?utm_source=tiktok&utm_content=__CID__

  • ?utm_source=tiktok&ref=__CID__

To set these up inside the TikTok Ads manager, navigate to the ad level and select an ad that you want to track with Cometly. There should be a section titled "Destination page" with a box for "Website URL".

Simply "copy" one of the above above (include the "?") and "paste" the code at the end of your Website URL in that section.

PLEASE NOTE: Make sure you do not use any of the above parameters more than once in your UTM string (i.e., do not use utm_campaign=__CID__ AND utm_campaign=paid in the same UTM string). ALSO - If there is another ? in your Website URL, that means you are already using UTMs, so you would need to switch the first "?" to a "&" before adding it to the end of your Website URL,

i.e. if your Website URL is

then instead of


you would want to add


So your Final website URL would be

Now you can go ahead and publish your ad. As long as you use this setup process on EVERY ad, your tracking and attribution with Cometly for TikTok ads will be PERFECT.
