Too many people live and die by the number of Facebook Likes they or their business gets - people need to realize that they are a pure waste of time with the recent changes in how FB shows your posts in the Newsfeed - right now they show about 2-5% of your followers your posts so building Likes is really a waste - especially when you read artciles about how so few people engage with a brand after they have liked it.
You need to get beyond the Like and go to actual people - engage with them make a real connection and don't spam them with comments about your products or services.
You can buy clicks in FB and make money - you can engage with people and have them follow you and talk with you and eventually they might buy something but it all is about making a real connection not getting some arbitrary Like
