Publicize Your WordPress Blog through Social Media
WordPress gives you the ability to easily integrate your WordPress blog with various social networks, like Facebook, Twitter, and LinkedIn, for example. Click the Sharing link in the Settings submenu on your Dashboard to load the Sharing Settings page.
In the Sharing section, connect your blog to popular social networks to automatically share your new posts with your friends within that network. WordPress allows you to share your blog on the following networks:
Click the icon for the social network you want to connect to and follow the steps provided to authorize your WordPress blog with that network.
WordPress.com's Sharing feature
Users of social media like to share the interesting content they find around the web with their friends on other social media sites, and the Sharing feature on WordPress.com gives you the tools that make it easy for your readers to share links to your content in different ways:
Email: Allows readers to e-mail your blog content to a friend
Digg: Allows readers to share your content on the Digg social media site
Facebook: Allows readers to share your content on the Facebook social media site
LinkedIn: Allows readers to share your content on the LinkedIn social media site
Reddit: Allows readers to share your content on the Reddit social media site
StumbleUpon: Allows readers to share your content on the StumbleUpon social media site
Tumblr: Allows readers to share your content on the Tumblr social media site
Twitter: Allows readers to share your content on the Twitter social media site
Pinterest: Allows readers to share your photos and graphics on the Pinterest social media website
Press This: Gives readers a button to click to easily use the WordPress.com Press This feature, allowing them to post links to your content on their own WordPress.com blog
Google +1: Allows readers to share your content on the Google+ social media site
By default, Email, Twitter, and Facebook services are already enabled. And in the Sharing Buttons sections, you can select the different social networks for your readers to share your content on. To enable any other service, click its button in the Available Services section and drag and drop it into the Enabled Services section.
After you’ve done that, small, convenient buttons display within each blog post on your site; your visitors can click these buttons to share your content with their friends on their own social networks.
WordPress Like button
If you’re a Facebook user, you’ll find that the WordPress Like feature is very similar to the Facebook Like feature that you use within your Facebook account to indicate that you Like a friend’s Facebook status.
On the bottom of the Sharing Settings page you can set your preference for WordPress.com Likes — select whether you want them turned on for all posts (by default), or turned on per post (so that you determine the placement of the WordPress.com Like on a per-post basis).
This feature does exactly what it says: It displays a Like button on your blog posts, allowing readers to click it and Like your posts within the WordPress.com network.
You can disable the WordPress Like feature at any time. Also, you can disable the Like feature on a per-post basis. This means that you can enable it globally, but disable it on individual posts if you publish a post that you don’t want people to be able to Like.
