Example: Customizing Schema for Web Tool Pages

Requirements

• The page must use a template with the slug template-tools.php
• The schema should be changed to WebApplication and enriched with relevant metadata

1. Change the Schema Type Using init_plugin_suite_review_system_schema_type

The following code checks if the post type is page and whether the page template is template-tools.php. If both conditions are met, it switches the schema type to WebApplication.

add_filter( 'init_plugin_suite_review_system_schema_type', function( $type, $post_type ) {
    $post_id = get_the_ID();

    if ( 'page' === $post_type && get_page_template_slug( $post_id ) === 'template-tools.php' ) {
        return 'WebApplication';
    }

    return $type;
}, 10, 2 );

2. Extend the Schema Data Using init_plugin_suite_review_system_schema_data

Once the schema type is changed to WebApplication, you can enrich the JSON-LD with fields like applicationCategory, operatingSystem, and offers. These are appropriate for free web applications.

add_filter( 'init_plugin_suite_review_system_schema_data', function( $schema, $post_id, $type ) {
    if ( $type === 'WebApplication' ) {
        $schema['applicationCategory'] = 'WebApplication';
        $schema['operatingSystem']     = 'All';
        $schema['browserRequirements'] = 'Modern browser with JavaScript enabled';
        $schema['offers']              = [
            '@type'         => 'Offer',
            'price'         => '0',
            'priceCurrency' => 'USD',
        ];
    }

    return $schema;
}, 10, 3 );

Result

When users visit a page using the template-tools.php template, the plugin will automatically render the following schema in the page’s HTML:

{
  "@context": "https://schema.org",
  "@type": "WebApplication",
  "name": "Page Title",
  "aggregateRating": {
    "@type": "AggregateRating",
    "ratingValue": 4.9,
    "reviewCount": 182,
    "bestRating": 5
  },
  "applicationCategory": "WebApplication",
  "operatingSystem": "All",
  "browserRequirements": "Modern browser with JavaScript enabled",
  "offers": {
    "@type": "Offer",
    "price": "0",
    "priceCurrency": "USD"
  }
}

Declaring the correct schema type allows Google to better interpret your content and may enable rich snippets for web apps in search results.
