Generating &/or tracking business leads

If you are running a social media for a business how would generate leads through instagram or at least track them.

Well, the lead would come through a link right? So I would create a custom link link mydomain.com/insta and track them through that.

But for generating them I would think it’s the same process as for growing the account.

Ya I was thinking of the same thing or just see how much traffic came to the site from instagram and so on. Or create a special code for the “sales” and so on.

I was thinking of the captions and a link to the site or where I want them to go would be one way doing the sales but I was trying to see if there was anything else anybody was thinking of doing.
