Hey guys, I want to hire a writer on iWriter to write an e-book for me, where I'll be placing my website's link at the end, as I heard it was good for my site. But I need help with some questions: 1. How long (in words) should be the e-book? Should it be generaly for my niche, or one of my site's keyword? 2. Where is the best place to upload the PDF with my link at the end? 3. Please suggest me anything I should know, Any help is realy appreciated! Thank you all.
