How the sharing buttons work
The social media sharing buttons on your page work exactly as you think they should: Each one is configured to share a link back to your book page!
You don't need to configure or edit anything. Each option contains a pre-defined message along with your specific Booklaunch.io page link. When a reader clicks on any of those options, a share window opens pertaining to the platform that was selected (e.g. a Twitter share box opens if the Twitter share button was clicked). The reader can then edit the message to his/her liking before submitting it to their social feed.
