I am struggling with this right now. I am not sure about the amount of time to put into each one. I want to start one in another niche but I am worried about the quality. Any advice?
Easier said than done. A real expert costs real money, other than that all you are going to get is professional article spinners that rehash stuff that they sold to someone else months ago, from copy and pasted stuff they stole from other article sites. You have to make a schedule and stick to it. It is very easy to get side tracked messing around online. Bookmark any future article ideas that you find while surfing so that you can find them later. Get you article writing down to a certain pattern so that you can put them out quickly while still maintaining the quality of information. Make a realistic goal to post when you know that you can, like say once a day, or twice a week. What ever it is stick to it.
