It’s easy to add UTM parameters to Facebook ads. Replace your destination links with:
replacing https://myurl.com with your own domain name. If you prefer, you can use paid or any other identifying word as the medium parameter.
You can also add a utm_term parameter and use it to track another element of your campaign. To do so, just append the above link with &utm_term followed by that data you would like to report, e.g. audience targeting information. UTM parameters are very flexible.
