Assuming that I have an idea which can monetize greatly. However, I have no knowledge on SEO, so I'm thinking of paying for SEO service. There are various SEO services on this forum offered with a very competitive price varying from $100+/month to $600+/month. The question is, should I use SEO service to promote my CPA site ? There is a thread out there where people tell their real income from CPA, and I notice: in that thread, the minimum income that one can achieve is approximately $1000/month, which cannot supply who lives in USA or Australia, Canada,...however, $1000/month is a very LARGE amount of money in my country (I live in a poor country); so I think using SEO service is not a bad idea ?
