I've set up a couple of blogs in various niches since last year.
One of which makes at least 1 $28 sale every week sometimes 2.
One of which has a few of my self produced products on and is now getting to the point of bringing in $300 or so a month.
This year, I'm going to research the holy hell out of my niche before choosing it this one is going to be the $1k a month year I can feel it
