Now that you've got an Author Central account, let's make it work for you.
So you'll want to make sure you link your Twitter account and blog. Twitter is pretty self-explanatory. For the blog, you probably won't be able to just list your website url. You'll need to do a little digging into the back end of your site and find your feed url. I was able to do this without an issue on my blogger account, but I've had trouble in the past linking accounts for authors on Wordpress. Amazon is a bit finicky so you might have to play around with it.
Next, you'll want to include any events you have planned. Remember that these can be live-events or online events. The purpose is to give your readers a chance to connect with you, so when in doubt, list it. This will require you to update it manually, so you might want to set yourself a reminder to update this monthly.
You can also include videos on your site. This can be a book trailer, interview, or just a collage of shots from some of your past events. Unlike most sites that allow you to link to a video on YouTube, Amazon requires you to upload the actual video file. They also set a limit at ten minutes and have size limitations, so keep this in mind.
The last area is probably overlooked by most authors, but is one of the best features of your Author Central account. This is your author page URL. It points folks directly to your Author Central listing on Amazon. Why is this great? Because your listing shows all your books. It's a perfect link to give folks when you have more than one or two books available. Of course, you'll have them all listed on your own webpage, but then visitors have to click on each individual book to go to a place they can buy it. When you are promoting your newest book, include a link to your Author Central account on any press releases or emails as an easy way for new readers to find all your books in one (easy to purchase) place.
