Tag Cloud help visitors to find posts related to a particular tag. Hence displaying tag cloud can help you in reducing the bounce rate and also developing some loyal readers for your blog.

Using an animated flash tag cloud can be visually exciting and add to the beauty of your blog. You can see an example on my blog in sidebar, in “TAG CLOUD” tab. This is added by installing a WordPress plugin named – WP-Cumulus.

It’s author says,

WP-Cumulus allows you to display your site’s tags, categories or both using a Flash movie that rotates them in 3D. It works just like a regular tags cloud, but is more visually exciting. Clicking the tags can be a little hard (depending on your speed setting) but does take you to the appropriate page .

With this plugin you can select the background color of your flash tag clod and also the color of tag links.

After installing the plugin, just add this code <?php wp_cumulus_insert(); ?>wherever you want to display your animated flash tag cloud.

The plugin can also be added as a widget.

You can download this plugin here.
