Showing a live link preview can be a cool trick to add to your site. Basically, when somebody puts the mouse over a link, it shows a preview of the page it leads to. This is done with a jQuery popup, which has a screenshot of the page. You can do this in WordPress with the right plugin.

The class="wp-live-preview" option will allow you to choose to display live previews manually. If you select this option, you can show the preview by adding this tag to your link code, such as:

&lt;a href="http://www.ExternalSite.com" class="wp-live-preview"&gt;External Site Link&lt;/a&gt;

Along with this setting, you can also adjust the size of the popup window, the position and how it is previewed. The default settings will work for most applications, but you may want to change the linking option at the top.

Now you know now to show live link previews in WordPress. You can use this plugin to help users see what they are about to find when they visit a link and improve the overall user experience.
