Tracking Facebook Mobile Visits to Desktop Conversions?

[YNWA]

Hi.

If I set an ad in Facebook, I can obviously track visits, conversions and so on from that ad and see if they where mobile or desktop.

However, how do I, if possible track a mobile visitor who the converts on a desktop?

Eg. I go on XXX Facebook Ad on my mobile whilst in work, look around. Like what I see. Then I go home from work, open my laptopn and go on XXX website and send an email enquiry form in.

Is this possible to track?

Thanks

Hi there, that's a great question. Unfortunately, as far as I'm aware, this would be difficult to implement; the only way I know of to do this is with cross device tracking via user ID in Google Analytics (Universal Analytics implementation). But that would only work if the user had logged in both on the mobile device and later on the desktop device. You could do a rough estimation of the FB driven later conversions by tracking micro conversions on mobile and then trying to correlate those with macro conversions on desktop, or something like that. But it wouldn't be very precise. Of course if there is a way of doing this more effectively that I'm simply not familiar with I would love to find out!

On a sidenote, it's worth noting that it's important to ensure that whenever you run a Facebook campaign, you tag it with the UTM tracking parameters, otherwise GA will likely misattribute it as direct traffic.
