If you have ever been successful with Facebook, you understand the value of high quality “likes”. Legitimate “likes” leads to
(A)Higher overall engagement rates on page posts
(B)Greater conversion percentages on “Suggested Posts”
(C) Lower cost per clicks due to high CTR.
All of these are a given but I think as a marketer the most important aspect of Facebook marketing is to understand the demographics of “users” that are buying my product then furthermore applying that understanding to other marketing campaigns such as “Display” or “Mobile”
This is the main reason why I strongly recommend that you never outsource your Facebook Marketing or buy incentivized likes from any third parties such as Fiverr
To recap, understanding your demographics is the greatest value of Facebook marketing cause you could really get to know your perspective customers rather quickly and affordably.
