3rd Milestone Reached: $100 a month
It is true when they say that things go up tremendously at one point. For the last 5 months I have been getting only around $10 a month, and that was because I didn't really sell anything.
To be honest, I am still not really selling anything, only writing about things that are in no shape or form connected to reviews or amazon.
I just added some affiliate banners and a simple landing page to my website, and it does the trick. Got $150 this month, wohoo! People are right when they say you should not focus on selling stuff. I do plan to write reviews but since a device I am constantly writing about isn't even out yet (comes out next year) I have a chance to focus on getting traffic.
And what kind of a lesson I learned from this? As cliche as it sound, do not give up. It literally took me 8 months to reach this, and I don't regret a single day, apart from the days when I didn't do anything.
