How To Setup Facebook UTM Parameters For Attribution Reporting:
We will not fetch the lead count from Facebook data directly. So that's why it is not showing Cost per lead (CPL) and no leads in the leads column. Since those leads data (opportunities lead value) lies within Highlevel, we build the attribution report to help you to determine the revenue you are earning in each campaign. The revenue would be the lead values you set for the opportunities.
Ad data comes from -> FB Ads
Lead / Sales data comes from -> Attribution reports
To see all columns both need to be set up properly.
