1-10

How hard is it to get a website to make $100 a month through AdSense from 1 to 10? Or $3-$4 a day?
Affiliate marketing is a better option of course but Amazon's Associates Program pays fucking NET 60.
I'm a begginer in this field so don't be harsh on me.

If you are a beginner in this field, then you should ask yourself whether you can rank a site at all first.

Adsense is definitely not something I would ever bother with anymore, considering the amount of people who use adblockers and the overall "ad blindness" that society has developed. That's however only small percentage compared to Adblocker.

All comes down to your budget and your skills. Site that would be 2 for me, might be 8 for you. It's subjective and depends on dozens of factors. So start reading, learning, do some keyword research and start working on your first site. Bear in mind, that ranking can take more than a year nowadays, even for lower competition keywords.
