How are the details validated? Well, the lead form automatically populates with the users Facebook details, so you know their name and email (and other details e.g. phone) are real.
This is great, however, you can only access these leads via a download. Sure, you can go in once or twice a day to get them, but it gets a pain. But I located some software, called SyncLeads, that connects to Facebook and transfers the details to my email autoresponder, so now the enquiry gets an immediate response, I am informed that that have made contact and I can add them to a campaign or CRM system.
In a couple days, we have seen enquiries shoot up and, most importantly, we have actually got newbusiness. Even better, is that the cost of acquisition is pennies, not pounds, in comparison to normal FB advertising - what a win!
By the way, there are several programs that will sync your contact details, however SyncLeads appears to offer the best value - let me know if you are aware of cheaper options!
