Starting today, when you publish a post, you’ll see a mention of the Publicize feature.
If you click Turn on the publicize feature, it will take you to the Sharing Settings page in your Dashboard. Here you can configure any of the Publicize services you like.
Pick one or more of the services you want to turn on. It’s required that you already have an account with each service you want to use, as you’ll be sent to the service and asked to log in to connect your WordPress.com blog.
Then, as seen above on the Edit Post page, WordPress.com will let you choose which services you want to send your post to. You can also customize the message you send along with the URL.
It’s now easier than ever to grow traffic to your blog. If you have more questions, you can read more about how Publicize works here. Happy publicizing!
