Ok - here's the thing. Yes, people can earn from almost any revshare site without getting referrals (the importance of having referrals). This will always be the case. These programs wouldn't last too long at all if they weren't able to say that to people and let it be that way.
The truth is - the majority of people out there are afraid to recruit or simply don't know "how" to get people to register into their program. I can totally understand this.
Heck - I remember my first experience of seeing network marketing in action.. and believe me, I was not interested in it, at all. Not even like one-half of one-half of one percent. haha
It was a big turn-off. There was no internet and people were actually out there walking around talking to people, in person!! "I would never do that", I told myself.
Fast-forward 24 years and things are completely different. Nobody needs to go out there and do it face to face with people. The internet makes it so so simple. The internet, combined with network marketing - was a match made in heaven.
Anyways, yes, people can earn money without sponsoring others. The problem is, it isn't much money. In a typical revshare program an adpack will get you back 110% to 120% as long as you do your daily activities (ad clicking) to remain qualified for that 24-hour time period.
That fact, above, is what appeals to the masses. The thing is.. unless you can either recruit OR you come in and purchase a bunch of adpacks, there won't be a whole lot of earning going on.
I recommend that you find a way to get referrals for your revshare business. It will make your life much easier. Become a people person, even if you don't actually go out and find these recruits yourself. No matter which revshare program you are involved in, you could find a site out there and actually buy referrals from that website. Some of these sites are highly sought-after and recommended by many.
Do whatever you can to get some teammates and then to work with this teammates. The entire network marketing industry is build-upon helping others to get what THEY want. Once you devote yourself to others, you can write your own check.
