It depends on the site I'm working on. Here on Bizdustry, it's just about 15-20 minutes per hour to make 3 posts.it is overload sometimes managing online job and offline job at same time. It depends on your time schedule and the kind of work you do offline and online. Their are jobs that allows you to manage both your online and offline job at the same time. And their are job you do offline and online that won't provide you with such time. Unless you leverage the time you spend on both to carve out some time to manage both.
Irrespective of your busy schedule everyday, how many hours do you devote to work online??
On faucets,its longer up to 30 minutes per hour. When I ran my business on Facebook, I worked about 5 hours or more each day.
