Earn on Facebook : Where to start

In this forum, I read so many post about earning money on facebook, selling like, share and comment, selling and buying facebook page and Ids. But my question is where to start.

I know very well about facebook and technology and concept related facebook. But what is the exact Road Map to earn on facebook.
1. Which nitch is best on facebook
2. How many Ids : I need
3. How many friends and followers : I need in every ID
4. How to Increase friends and followers
5. How to Get more Like and How many Likes I need
6. How to Increase Engagement
7. How to Monetize Page to Earn Money

I Know a little answer of every question but I am not sure what is exact answer. I never earned on facebook. If anyone who earned on facebook Please tell me.

OK
1. you need to find the niche your self, no one will do the dirty work for you!
2. More the merrier
3. More the merrier
4. Use search already lot of threads in that topic
5. Use search already lot of threads in that topic
6. Use search already lot of threads in that topic
7. Use search already lot of threads in that topic

And if you know little answer of every question then go and start testing and learning, why do you think someone will tell you his/her secrets that they have spend months or more learning and testing?

I am completely agree with you sir. No one is going to tell me secretes. I am not asking about secrets. I am thinking to get some clue.

maybe the best answer is google then test what you learned.

if you knew that questions, not easy earn money on fb, trust me

My suggestion is to network and communicate on facebook, or going against FB Terms of service and creating giveaway types of things and telling others that you are giving away things if and earn off of CPC, or CPA. Other than that facebook is hard to earn off of, especially the ads unless you have a pretty decent following already.
