This guide provides instructions for how to connect your WordPress.com site to various social networking services. Once connected to a service, you can share your posts with that service automatically. This feature is available for sites hosted on WordPress.com or using the Jetpack plugin on a self-hosted site.
To connect your site to your social networks, go to the My Sites tab → Sharing.
You’ll see various services in the Connections section: Facebook, LinkedIn, Path, Tumblr, and Twitter. To connect to a service, select that service and tap on Connect.
Note: You can only connect and automatically share to the services listed in this section. Some services, like Instagram, do not allow other sites like WordPress to automatically publish content to your account on that service. In that case, we can't offer sharing for that service.
