I make around $100 a month. It's a combination of things. My goal is 155 sb a day - that'll get me $50 a month, anything on top of that is gravy. The hideout.tv videos will run without having to pay much attention to them, so I get 15-30 sb a day from those depending on if I stay on top of it or not. Today I cashed in 12 from yesterday. The daily poll is 1 sb, 13 sb from survey disquals, 10 sb bonus for completing my to do list, 2 sb from the "watch" item on my to do list, 20 sb from the "laptop guy" videos that are about 30 seconds or less, 8 sb from the "tank top girl videos" that are about that long as well, 15 sb from search wins, and a 75 sb survey. That's 156, and I mostly did it while drinking my morning coffee and eating breakfast. There's also paid "money maker" offers if you keep up with what's posted here and on reddit. People on reddit post easy SB earns when they find them - newsletter signups and whatnot. You eventually start learning where to look and what's worth it and what isn't. I struggled with surveys today, sometimes I qualify for the first one I try - its all very hit or miss. I'm working on a casino slots game that will pay about $2, and I can let it run on my phone on auto-spin until I run out of credits, then wait two hours for my next batch of bonus credits. It hasn't involved me paying hardly any attention to it at all. Sometimes you can get points for just installing games - install, open, get SB, delete.
It's definitely a learning process, but these days I can crank out my personal goal fairly quickly, and do more depending on what easy offers are floating around.
