Hi
Congrats for your success!
Iam new to IM,may i have some questions?
I was thinking about something similar :ranking with articles and cpa content lock.
I dont have the tools u mentioned in your method(iam planning to buy them),but what about just:
writing articles 2-3x 500 words and submit them to 150-200 PR4+ Directories (it costs 5$)+ get some edu and gov links(its costs 10$ with 3x700 words articles).
With a domain it could be only 20$/site.I found some keywords between 2000-4000 monthly searches without real competetion(weak onpage seo and only 5-10 backlinks).
Can i rank my site with this method or its not enough?
What do you think?
Can you suggest something wich is cheap/easy/fast?

Thanks in advance and sorry for my english,
Gy
