Prospecting on Facebook is a medium to long term strategy and nobody gets results on day one. That warning opens the most detailed post here, and what follows is an actual method. Find the groups where the people you want already gather, make a genuine connection, and only much later move toward a conversation on the phone.
The content post makes a related argument. Put yourself in the position of the person searching, work out what they are actually trying to solve, and write that. Traffic follows from being useful rather than from being clever.

The lead generation material assumes you are building a team and want something you can teach to somebody else.
Read the prospecting post if social media has felt like shouting, and give the method the months it asks for.
