Being your own business means looking after all the steps in the process. While the web allows great opportunities, it is a bit of a moveable feast in that what was good practice six months ago may now be old-fashioned, and sources of information soon grow old. If you have a book on Kindle you are about to promote with a KDP Select free promotion, you need to advertise the fact.
If like me you are about to promote a title (in my case The Marylebone Magician) you need a good list of sites that are still live. In this case, CM Skiera has come to our rescue with this well-time post: KDP Select Free Book Promotion Links. What I like is not only are these all recently tested, but the post also reminds us to keep a handy list of details ready before starting on the process!
