Want to add a special message or ad code to your most popular blog posts? This plugin enables you to do just that!
<ol>
<li>Install and activate the plugin via <code>WP-Admin > Plugins</code>.</li>
<li>Mark your top posts as “Premium” using a checkbox in the Post Editor.</li>
<li>Go to <code>WP-Admin > Settings > Reading</code> and edit your premium post message.</li>
<li>Choose to place your message above or below the post content, or place it manually using the <code><?php premium_posts(); ?></code> template tag inside <a href="https://codex.wordpress.org/The_Loop" title="WordPress Codex: The Loop" rel="nofollow ugc">The Loop</a>.</li>
</ol>
This plugin also adds the conditional tag <code>is_premium_post()</code> for use in your theme template files. You can use it to test if a specific post is marked as premium by passing the post ID (or post object) as a parameter.
Example:
<pre><code><?php if ( is_premium_post( $post_id ) ) { ?>

 <?php echo get_the_title( $post_id ); ?> is a premium post!

<?php } ?>
</code></pre>
