This plugin searches your posts for YouTube embeds and then wraps the player with share buttons that appear on hover when view on desktop or display on place when view on mobile devices. There’s both a share button for Facebook and for Twitter that share your current post URL. When the post share on Facebook, it share the full URL. When sharing on Twitter however, it uses the shortlink, so that the tweet does not surpass the 180 character limit. It works with both regular YouTube iFrame embeds and the oEmbed system.

Genesis Simple Share is created to be simple and easy to use within your Genesis child theme. We have tried to focus on making default options and initial setup a breeze.
The default settings should automatically enable the share icons on posts. You may wish to make some changes so in your WordPress dashboard hover over the Genesis menu item and click the Simple Share menu item in that submenu.
Once there you can choose which post types Simple Share will be active on, if it should show on archives, and which icons to enable. You can also drag and drop the icons to change the order they will display in on your site. You may wish to add your Twitter user name to the twitter icon settings. This will add a via: @username after the share text on Twitter. You may also add a URL to an image to use as the default image.
