I got to thinking about what Joe was saying with new visits coming from FB and he would take notice after a certain percentage. As I woke up wide awake at 5:45am this morning 
- I realized that this most likely will never occur with my facebookers. Why? Because I already have an established relationship - at least one that makes them want to "like" me on FB.
To get to a 70% new visit I would have to have some sort of marketing campaign for new customers that drives them to my FB page then hopefully send them to my site. It could work - but I would rather create a page on my site that I could drive people too rather than my FB page.
I don't think facebook for a dealer is about driving brand-new-never-done-business-with-me-before-customers to my site. This can and will happen with the virality of FB - but I think my current customers are more apt to befriend rather than strangers.
So the question becomes - do you create campaigns to drive folks to your page and build the relationship there and then drive them to your site? Do you drive your current customers to facebook site to like you so they can keep up to date with what you are doing in the community, see what you are posting that is of interest to them, and/or see the specials you might have?
Or a combination of all of the above?
I like Jeff's thinking about tracking this through Google Analytics and seeing if it will convert to a lead - but as Joe pointed out - we might be disappointed in what we find.
Ahhh....facebook. Now off to close out the month! YAHOO!!!!
