Hi! Mate, you have taken a better plan. I'll also prefer passive income.
I understand you are taking a better plan and you are researching about that. That's really good. For doing better things a better plan is crying needed.
I'm also an Amazon affiliate so I can prefer you to continue these way. I believe if you can continue these then you'll able to make more than $20 per day.
For these first, you have to reduce you site rank. I'm also running these business in my own site. First I was created that sites and then I promoted them last of all started Affiliate and Adsense.
If you are strategic then it'll take few month. You have to develop these site without spam posts and all contents should be unique and niche related.
Please keep update. What's going on.
