Tracking My Site Visitors to Facebook

Hi guys

I'm running a local business site that's ranking pretty well for a few major keywords in my niche.

The thing is I'm not getting many queries from my site (contact form/call tracking) but a lot more from my FB messenger.

I have a hunch that my visitors will check my site and then look for my business on FB to check my reviews and then FB message me.

Is there a way to track how many of these leads orginated from my site before ending up on FB?

It would help me dial in on my on site conversion rate.

Thanks!

I think this is what you are looking for.
