You can learn a lot about marketing and still have no idea how to set up a WordPress website or integrate your mailing list or
design optin offers or set up drip content; you can understand what you need to do without actually knowing how to do it.
The truth is there is too much competition, and unless your publisher is doing brilliant content marketing, building a genre specific email list, helping you build your amazing author website and boosting your
optin offer, counseling you on social media strategy and long term book sales, you've basically signed away a big chunk of your sales in exchange for editing, formatting and
design.
