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.
<h4>Features</h4>
<ul>
<li>Includes 6 core buttons: Twitter, Facebook, LinkedIn, Reddit, Pinterest, Pocket</li>
<li>Includes lightweight SVG-style alternatives for each service</li>
<li>Display sharing buttons above or below content</li>
<li>Supports floating button bar (left or right)</li>
<li>Buttons can be aligned left, right, or center above the content (non-floating)</li>
<li>Call-to-action section with editable text and layout</li>
<li>Custom post type support</li>
<li>Developer-friendly with actions and filters</li>
<li>Minimal footprint and modernized layout</li>
</ul>

Note: For proper social metadata (e.g., titles, images), I recommend using a dedicated OpenGraph plugin.
