We suggest to use a (branded) tracking with a parameter together with conversions tracking.
In other words, this is the flow if we use as sources Facebook vs Google, for example:
1. create a tracking link with a parameter like jo.my/alias?ep00=facebook (the parameter name in this case is facebook, but it can be google or whatever else you want to track as a source). Please use a custom branded domain to create your tracking links, since the latter has several advantages your side. If you want you can expose a clean branded tracking link to your users and redirect it to the "internal" branded link which has the parameter.
2. create a conversion and associate the conversion to the above tracking link (jo.my/alias?ep00=facebook) + put the corresponding conversion code in your TYP, namely the page after the lead is acquired (edit the conversion in the dashboard then copy and paste the conversion code, once, in your TYP before the closing "body" tag).
3. the tracking link will forward the parameter to the conversion. If a conversion takes place JotUrl will register it within your Analytics. Therefore you can go to the analytics section within the dashboard, later on, and check how many conversions were driven by the "Facebook" source and how much from the "Google" source.
