You have written a compelling story, it is published, and readers are reading it. Great! If you have not already started an author website, you are going to want to. Why? Because once a reader falls in love with your writing, they are going to want to learn about YOU. They will want to connect with you, and you will want to connect with them.
The best way to connect with your readers is to have an author website where you can make those connections. Social media is great, but you will need a more solid platform to withstand the long run. If you have a blog on your website, you can share what is going on with you and your writing daily or weekly. A website is a perfect way to put your contact information, where and when your books signings, talks, and workshop are. You can also have people sign up for newsletters or updates,
Don't forget to provide the URL to your website in your books' copyright page and if you have press information and a few usable pictures, short and long bios on your site that you can direct the media to, you will be more likely to get full media coverage.
You are an author. You know how to write. Having an author platform is you writing a story about you and your books. It is a vital part of being an author, so get writing.
