Robin Good: Paul Jun has an excellent itroductory article on self-publishing your first ebook on the Amazon Kindle, laid out in seven clear steps.
1) Define your target audience
Without a target audience, an eBook is useless.
Without a target audience, you will not see an increase in subscribers, traffic, or any building of trust whatsoever.
2) Have a place online (a website) where people can find you and ask you questions
3) Go for the writing.
4) Tools you need before formatting
5) Formatting issues
6) KDP Select or not?
7) Upload the eBook - cover, royalties, ISBN number
N.B.: Paul has truly some great tips and recommendations on how to leverage best the different routes offered by Amazon to ebook publishers (KDP Select or not?)
Great guide. Highly recommended. 9/10
