Dei uma olhada em um dos seus artigos, e realmente seu tema não oferece suporte para Marcação de Dados Estruturados!

Você pode tentar modificar sua template single.php
Tente implantar o código de marcação de dados abaixo!

<div itemscope itemtype="http://schema.org/Article">
  <meta itemscope itemprop="mainEntityOfPage"  itemType="https://schema.org/WebPage" itemid="<?php the_permalink() ?>"/>
  <div itemprop="image" itemscope itemtype="https://schema.org/ImageObject">
    <meta itemprop="url" content="url da imagem">
    <meta itemprop="width" content="900">
    <meta itemprop="height" content="500">
  </div>
  <h2 itemprop="headline" class="">
    <?php the_title(); ?>
  </h2>
  <meta itemprop="alternativeHeadline" content="subtitulo">
  <meta itemprop="description" content="descrição">
  <div class="" itemprop="articleBody">
    <?php the_content(); ?>
  </div>
  <meta itemprop="datePublished" content="<?php the_time( 'c' ); ?>">
  <meta itemprop="dateModified" content="<?php the_time( 'c' ); ?>">
  <span itemprop="author" itemscope itemtype="https://schema.org/Person"> Por <span itemprop="name">
  <?php $author = get_the_author(); ?>
  </span> </span>
  <div itemprop="publisher" itemscope itemtype="https://schema.org/Organization">
    <div itemprop="logo" itemscope itemtype="https://schema.org/ImageObject">
      <meta itemprop="url" content="http://sitiodocambuci.com.br/wp-content/uploads/2016/02/xSitio-do-Cambuci-logo.jpg,qc912e7.pagespeed.ic.fUIniP6ssy.webp">
      <meta itemprop="width" content="240">
      <meta itemprop="height" content="90">
    </div>
    <meta itemprop="name" content="<?php echo get_bloginfo( 'name' ); ?>">
  </div>
</div>

Adicione este código em ( functions.php )

function wpb_set_post_views($postID) {
    $count_key = 'wpb_post_views_count';
    $count = get_post_meta($postID, $count_key, true);
    if($count==''){
        $count = 0;
        delete_post_meta($postID, $count_key);
        add_post_meta($postID, $count_key, '0');
    }else{
        $count++;
        update_post_meta($postID, $count_key, $count);
    }
}
remove_action( 'wp_head', 'adjacent_posts_rel_link_wp_head', 10, 0);
function wpb_track_post_views ($post_id) {
    if ( !is_single() ) return;
    if ( empty ( $post_id) ) {
        global $post;
        $post_id = $post->ID;
    }
    wpb_set_post_views($post_id);
}
add_action( 'wp_head', 'wpb_track_post_views');
function wpb_get_post_views($postID){
    $count_key = 'wpb_post_views_count';

        update_post_meta($postID, $count_key, $count);
    }
}
add_filter('manage_posts_columns', 'posts_column_views');
add_action('manage_posts_custom_column', 'posts_custom_column_views',5,2);
function posts_column_views($defaults){
    $defaults['post_views'] = __('Visualizações');
    return $defaults;
}
function posts_custom_column_views($column_name, $id){
    if($column_name === 'post_views'){
        echo getPostViews(get_the_ID());
    }
}

Criando a template ( topartigos.php )
Seus posts serão exibidos por número de visualizações.
Do mais visitado para o menos visitado!

<?php
/*
Template Name: Top Artigos
*/
get_header();
?>
<article id="post-<?php the_ID(); ?>" class="art-post art-article">

<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<?php if(is_home() && $post==$posts[0] && !is_paged()) echo ' firstpost';?>
<ul>
<?php $popularpost = new WP_Query( array( 'post_type' => 'post', 'posts_per_page' => 24, 'meta_key' => 'wpb_post_views_count', 'orderby' => 'meta_value_num', 'order' => 'DESC'  ) ); ?><?php while ( $popularpost->have_posts() ) : $popularpost->the_post(); ?>
<li><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></li>
<?php endwhile;?>
</ul>
<?php endwhile; else: ?>
<?php endif; ?>

</article>
<?php get_footer(); ?>

Adicione esta linha em ( single.php )
<?php setPostViews(get_the_ID()); ?>
