When you publish your book on Amazon, be extremely careful with your author name. Be certain of the name you want to use before you publish your first book. Don’t use a slightly different name for your second book.
When you complete the details of the book during the publishing process, enter the name exactly as you want to use it for the rest of your publishing career. While you can jump through hoops and spend time discussing the matter of changing it with Amazon, save yourself the hassle and do it right the first time.
When I say enter the name exactly, I mean exactly. Understand that Amazon sees your name as it would a file name. Diane McGyver is not the same person as Diane Lynn McGyver or Diane L. McGyver or Diane L McGyver or Dr. Diane McGyver. No, I’m not a doctor. I’m using this as an example.
When you use exactly the same name, the computers at Amazon automatically link your books and create an author page with your author biography and a list of your books. Readers will find all your stuff in one location.
Amazon will not link Diane McGyver with Diane L McGyver. Readers will click on Diane McGyver and see books only published by her, not Diane L. McGyver.
If you make a mistake or tweak your name, you cannot change it in the detailed information. It, like your title, is permanent. Unless you go through the hassle of explaining the situation to Amazon and hoping they will understand and change it.
The easiest thing to do is use the same name from the start.
