just understand the information they are selling... they will only tell you that you can market clickbank products with google adwords and when the clickbank product sells you get money... simple just read the stuff... they are giving... they have given a form exactly as adwords and also i think they have given screenshot of clickbank earning... hope this information helps...
Don't waste your money buying that crap! Instead you can search data entry jobs at any freelance sites like www.rentacoder.com, www.scriptlance.com or www.getafreelancer.com
I can't stress enough. Do not buy what people are selling ! Make people buy what you are selling. Can I get an amen ?
