numero de visitas no post

Ola, bom dia
eu queria implementar um codigo <?php if(functions_exists('the_views')) {the_views();} ?>, para que ocorra uma contagem do numero de visitas de um post!
Não sei o lugar certo de por o código!
index.php

<?php
/**
 * The main template file.
 *
 * This is the most generic template file in a WordPress theme
 * and one of the two required files for a theme (the other being style.css).
 * It is used to display a page when nothing more specific matches a query.
 * E.g., it puts together the home page when no home.php file exists.
 * Learn more: http://codex.wordpress.org/Template_Hierarchy
 *
 * @package Able
 * @since Able 1.0
 */

get_header(); ?>

	<div id="primary" class="site-content">
		<div id="content" role="main">

		<?php if ( have_posts() ) : ?>

			<?php able_content_nav( 'nav-above' ); ?>

			<?php /* Start the Loop */ ?>
			<?php while ( have_posts() ) : the_post(); ?>

				<?php
					/* Include the Post-Format-specific template for the content.
					 * If you want to overload this in a child theme then include a file
					 * called content-___.php (where ___ is the Post Format name) and that will be used instead.
					 */
					get_template_part( 'content', get_post_format() );

				?>

			<?php endwhile; ?>

			<?php able_content_nav( 'nav-below' ); ?>

		<?php elseif ( current_user_can( 'edit_posts' ) ) : ?>

			<?php get_template_part( 'no-results', 'index' ); ?>

		<?php endif; ?>

		</div><!-- #content -->
	</div><!-- #primary .site-content -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>
