Write your blurb like a normal human. Get the HTML Amazon actually accepts.
Paste the HTML into the KDP description field. Allowed tags only: b, i, u, em, strong, br, h4, h5, h6, ol, ul, li. The counter measures the HTML against KDP's 4,000 character limit.
Formatting the blurb is the easy part. Writing it isn't. Soon the minion will write your description, keywords, and categories straight from your manuscript. Get launch access.
