media buying, how to?

So I want to get started with media buying. I've read a lot of posts about mediabuying, but I want to know some things:

1. Do I need a Landing page or can I just use a direct link?
2. How are the conversions on Social media?
3. How much should I spend on my first campaign?
4. How much can you earn?

I can spend about 2 hours a day. I don't have a lot of money (100$) so how do I get started with this small amount of money?

Google is your friend..

1. Do I need a Landing page or can I just use a direct link?

LP's works best especially with diet.

2. How are the conversions on Social media?

YES, for DIET, Muscle and Dating Social media is best.

3. How much should I spend on my first campaign?

$25 till you can get first conversion. If you don't make any money, start testing 2nd offer.

4. How much can you earn?

Depends on how quickly you can learn and invest on it.

P.S Remember, FB is not lenient as it was before. If you got ad account utilize it carefully. For mediabuying, you will need budget around $1,000 minimum for testing.
