What is the author's platform? It stands for you and your book, your credibility as an author. Just like a politician you have to get your book out there to make sales. You also have to get yourself out there and become visible to your readers. It a reader doesn't know you exist how can they buy your book? Social media is not enough.

All the famous authors are out there giving talks, going to conferences, speaking where ever they can to get in front of their readers. If you want to be noticed and sell you books you have to get your butt out the door.

I personally love to go to arts and craft fairs with my book. I love the feed back I get from a reader when they come back to by the next book. Several times a readers, standing at my table will convince someone to buy one of my books. It's thrilling when that happens. 

My  little book, The Author's Platform: What it is and why you need it, is loaded with easy ways to use social media and outside events to improve your sales. https://amzn.to/3pPWXjZ
