I was a little bit skeptical regarding being paid by "leads", it really works, basically when you promote your agency (I use influencers) you get a lot of people on your website. If the person searches for hotels, you get paid a certain amount of money (even if he doesn't books anything). The only thing i've noticed is that the income for leads changes based on how many booking you close, (if in 2 months you get only leads and 0 bookings they give you less money). I make on average $115/day and spend $5/$20 in ads. The good thing is that is automated I just think about making good ads.
