Self-Publishing with Ingram Spark. Things I learned:
Get your book reviewed first, before you launch it so you'll have reviews on your cover.
Make sure your website and/or blog are working well before you publish and send it out there for the world of readers to stumble over.
Ingram Spark really does distribute your book to a lot of different bookstores/online book sellers, so about a week after publishing have fun googling your book to see where it lands.
Learn how to make buttons and shortened links. I'm using Bitly to shorten link.
Study what metadata is and don't be fooled by bots on FB who message you that you've got it all wrong.
Search for local bookstores that may be happy to have you do a book signing and/or purchase your book for their shelves.
Don't get too excited about Amazon selling your book because other small book sellers may actually provide a discount and some people would rather support them than Amazon, so provide more links than just Amazon on your website/blog.
