Add the social media like “Copy URL button” and make it easy for visitors to copy the URL of a specific page or post on your blog.
The Copy URL button plugin can be used inside the Worpress editor using shortcodes or use PHP to echo the content of the shortcode inside the template files of your WP theme.
Currently the plugin supports two display types:
<ol>
<li>Default – The button looks like a social media button including count “bubble”.</li>
<li>Small – Add the size=’small’ parameter to the shortcode and the button looks like a small share button without share count.</li>
</ol>
This plugin doesn’t create links for you, but instead improves usability and makes it easier for visitors to copy or share the URL of a specific post or page.
