FeedBlitz's RSS subscriber tracking offers many ways to share posts for RSS readers, including Twitter, Pinterest, and Sharing with Facebook.
The "Like" button is enabled by default for new RSS feeds; publishers with RSS feeds created before August 16, 2010 can add the Like feature under the “Per Post Sharing” option.
In order to make changes to your social media sharing options, select your RSS feed on your Account Dashboard. On the next page, click the “I Want To” button in the upper right area of the page.
Next, select the “Per Post Sharing” option from the drop down menu. On the next page, make sure the “Social Media” tab is selected. From here you can check or uncheck your desired social media options.
