I think to make a site to earn around 200$ a month. So if i get it right, with CPC of 1$ and CTR of 1%, i need 20,000 PV each month. How do I get this PVs? I need to search for 20 different keywords with more than 1k searches per month and rank my site on 1#? Or I need to make site for each keyword? If you got a tutorial so I can read, I would really appreciate it. btw, how many words I need per article? 500 is enough?
