  • Hi there,

    you have two major bugs to fix in your schema.org implementation. File stars-rating-public.php, line 120 and below.

    My suggestion:

    
    public function add_reviews_schema() {
    
                if (!self::status()) {
                    return;
                }
    
    			$schema_name  = ucfirst( get_post_type() );
    			$schema_title = get_the_title();
    			$rating_stat  = $this->rating_stat();
    			$review_type  = get_option( 'google_search_stars_type' );
    
                if (!empty($review_type)) {
                    $schema_name = esc_attr($review_type);
                }
    
                $rating_value = ($rating_stat['avg']) ? $rating_stat['avg'] : "n/a";
    
        if(intval($rating_stat['count'])> 0) {
                        echo '<script type="application/ld+json">
        {
            "@context": "https://schema.org/",
            "@type": "AggregateRating",
            "itemReviewed": "' . $schema_title . '",
            "ratingValue": "' . $rating_stat['avg'] . '",
            "bestRating": "5",
            "ratingCount": "' . intval($rating_stat['count']) . '",
            "name" : "'.$schema_name.' review"
        }</script>';
                    }
            }
    

    Reason: First of all there are schema.org errors if there are no ratings because values are required. Therefore the if condition. Second thing is, that @type has to be a valid schema.org type like “WebPage” or “Product”, it is not the case for the most post type and a misuse of that property.

    Check my implementation suggestion – what do you think? This way it will not conflict with yoast or others.
