Advertising clickbank job "products" on craigslist.. a few questions.

I'm trying to learn how to get consistent conversions on clickbank so I've been promoting tons of products everywhere.

I noticed I haven't really promoted any "job products" so thats what I'm doing now using craigslist.

My question is, HOW do these places make their money? Say for an affiliate site like "realwritingjobs.com", where is their money coming from?

They must be charging a registration fee because it says "$21.16" on their clickbank listing (although it doesn't mention anything about a fee on their site).

So how do these job sites work & are they "scams"?

I am making tons of listings on CL through various accounts and trying to promote realwritingjobs.com. I'm not posting my affiliate link in the listings, rather I wait for people to email, then send a second message with my link.

In this message I qualify them further and condition them so they will trust the link when I send it. Since its a shortened link that looks shady, I'm telling them "every applicant gets a unique tracking link that notifies us when they register with the site". This way when they see the link isn't a professional looking business url, they don't get shaded out over it.

This is whats bothering me though.

Considering they have a good gravity score, if they are charging people and not mentioning this requirement on the site, thats going to kill my conversions.

So should I tell them on CL that they have to pay to work this position? That will sound like a blatant scam.

Let me leave this off here obviously I have no idea how these offers work. If anyone has any insight to this I'd appreciate it.

Thanks! - Red
