Bug with Structured Data in Rating

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.

Can you fix this?
