Around a year. But on the other hand, when I started I had nothing except a shitty free-host website on a free domain.
It took me about 8 months from when I started. A lot of it depends on what kind of product, service, or advertising you are providing and what you know on marketing it.
For me it took 10 months, but for the first 5 or 6 months I didn't know exactly what I was doing, and didn;t know what my goal was.
well it took me like 2 weeks to set up my own system. Now, i get ppl to set that up and running in 3-5 days. My daily take is around $150 to $350 per day over 10 blogs. and a learning curve as I fleece out the better paying niches.
I dont know what you consider "decent money", but after about 4 months i was earning over $1000 per month..
I depdens on a lot of factors like: - the niche you choose - the amount of traffic you drive - are you're visitors willing to click the ads ( you can drive thousands to your website but if they don't see an add that sparks some kind of interest...they will not click).
It depends on the niche you choose, if your site niche is health related or forex , you can earn average $0.25/click
Its going to depend how quickly you can get traffic more than anything. This will depend on the amount of work you put in. The amount of content you are putting on the site, the amount of links you are getting, etc.
