If you are on the genesis system and want to have previous and next post navigation you can add the code below to your functions.php file. This is a great way for people to navigate though the posts on your website.  

/** Genesis Previous/Next Post Post Navigation */

add_action( 'genesis_before_comments', 'eo_prev_next_post_nav' );
 
function eo_prev_next_post_nav() {
  
	if ( is_single() ) {
 
		echo '
<div class="prev-next-navigation">';
		previous_post_link( '
<div class="previous">Previous article: %link</div>

', '%title' );
		next_post_link( '
<div class="next">Next article: %link</div>

', '%title' );
		echo '</div>

<!-- .prev-next-navigation -->';
 
	}
 
}

In your style sheet you can style the buttons how you like

Here is an example. You can add this to your style.css in your child theme.

.prev-next-navigation {
  margin: 20px 0;
	clear: both;
	overflow: hidden;
}

.previous {
	float: left;
	width: 50%;
}

.next {
	float: right;
	text-align: right;
	width: 50%;
}
