If you are using an existing post on your FB ad, follow the instructions below to make sure the UTMs are set up properly on the ad.

When editing the ad, there will be no box for "Destination" because the Website URL will be pulled from the original ad. Because of this, you will need to use the "Tracking" section at the bottom of the ad. In the Tracking section, you will see a box labeled "UTM parameters". You will paste the UTM code into this box and remove the "?" at the beginning of the UTM code as displayed in the screenshot below:

Now you can go ahead and publish your ad. As long as you use this setup process on EVERY ad that uses an existing post, your tracking and attribution with Cometly will be PERFECT.

For any remaining ads that do not use an "existing post", return to the main article Setup your UTMs for Shopify.
