[Silhouette]

Fair enough: if getting someone to Like you on Facebook turns out to be one step in a funnel that does convert a significant number of people in the long run, then yes, that has a measurable value.

I think the sceptic in me says that if you didn't get a worthwhile hit from a targeted ad spend, and if the Likers are only a subset of that target market, many of whom didn't even leave Facebook to visit your site, then it's unlikely to give a worthwhile conversion rate down the line either. Maybe the sceptic in me is wrong on this one, but only time will tell...
