Here is a quick way to list/display the most popular tags. The code should be self explanatory, the function “get_tags” is used to get all the tags along with some custom arguments that you can provide to it to get the most popular tags.

<?php 

    $args['orderby'] = 'count'; 
    $args['number'] = '11';//number of tags we want to fetch 
    $args['order'] = 'DESC';


    $tags_list = get_tags($args);
    //print_r($tags_list);
    //echo '<pre>'.print_r($tags);
    shuffle($tags_list);
?>
<div>
    <h1>popular tags</h1>
    <ul>
<?php 
    foreach($tags_list as $tag)
    {
        $tag_link = get_tag_link( $tag->term_id );
?>
        <li><a href="<?=$tag_link?>"><?=$tag->name?></a></li>
<?php         
    }
?>
    </ul>
</div>
