Socialize makes it easy to add relevant social sharing buttons to your posts and pages without clutter or complexity.
You can add sharing buttons in two locations: 
1. Above your post content, left, right, or center aligned (or floating on the left or right) 
2. In a call-to-action (CTA) box below your content
Unlike many other plugins, Socialize provides a panel within the post editor for selecting which buttons appear per post. This helps you display only the most relevant sharing options to encourage engagement.
You can also display a customizable CTA box below the content. Use this space to ask readers to comment, share or take another action. You control the message and which buttons appear here, on a per-post basis.
All visual elements, including button layout, floating behavior, and CTA styles, can be modified in the plugin settings. Developers will also find useful actions and filters for extending functionality.
