How To Create Product Review Schema In WordPress Without plugin

As an SEO expert with over a decade of experience, I've witnessed the ever-evolving landscape of search engine optimization. One crucial aspect of SEO that has gained significant importance in recent years is the implementation of structured data, specifically Product Review Schema. By incorporating this schema markup into your WordPress website, you can provide search engines with valuable information about your product reviews, ultimately improving your search engine visibility and driving targeted organic traffic to your site. In this guide, I will share my expertise and guide you through the process of creating a Product Review Schema in WordPress, without relying on plugins. 

Understand the Product Review Schema Markup 

Before diving into the implementation process, it's essential to familiarize yourself with the Product Review Schema markup. This schema provides search engines with specific details about your product, including its name, description, average rating, and reviewer information. By structuring this information in a standardized format, you can help search engines understand and display your product reviews more effectively in search results. 

Step 1: Add Schema Markup to the Template File 

Once you've located the relevant template file, open it using a text editor. Insert the necessary Product Review Schema markup within the appropriate HTML tags 

Step 2: Validate Your Schema Markup 

After adding the Product Review Schema markup to your template file, it's crucial to validate it to ensure it follows the correct structure and syntax. Utilize the Structured Data Testing Tool provided by Google or other schema markup validators available online. This step helps identify any errors or warnings that need to be addressed.

function add_rating_ld_json_markup() {
    global $product;

    if ( ! wc_review_ratings_enabled() || ! is_a( $product, 'WC_Product' ) ) {
        return;
    }

    $product_id = $product->get_id();
    $rating_count = get_post_meta( $product_id, '_wc_review_count', true );
    $average = get_post_meta( $product_id, '_wc_average_rating', true );

    if ( $rating_count > 0 ) {
        $ld_json_markup = array(
            '@context'       => 'https://schema.org/',
            '@type'          => 'Product',
            'name'           => get_the_title(),
            'description'    => get_the_excerpt(),
            'aggregateRating' => array(
                '@type'       => 'AggregateRating',
                'ratingValue' => $average,
                'reviewCount' => $rating_count
            )
        );

        // Output the ld+json markup
        echo '';
    }
