At the very beginning, I started with 3 tumblrs on different niches just to test it out and see what I can get. To my surprise, with no marketing, no liking other people's stuff, no reblogging, I only queue interesting pics and I'm able to get about 200 uniques/day from these 3 tumblr blogs in just about a week or so. To be honest, I have no idea how people found out my tumblr posts since what I've done with them was just queue posts and leave them alone. Anyway that was a good sign so I'm starting to scale up. But none of my other tumblr blogs which was built afterwards get a single follower, and no traffic as well, even the contents are better than the previous 3. I'm kinda lost with this interesting scenario. Apparently what has happened to my first 3 blogs are pure luck? What do you guys do to get followers/traffic?
