Removing Published Date from Article Schema

In some cases, search engines like Google may display the publish date of your articles in their search results. If you’d like to prevent search engines from displaying the publish date, you can use the code snippet below to remove it from the JSON schema that AIOSEO outputs.

add_filter( 'aioseo_schema_output', 'aioseo_filter_schema_output' );

function aioseo_filter_schema_output( $schema ) {
	foreach ( $schema as $index => $graphData ) {
		if ( empty( $graphData['@type'] ) ) {
			continue;
		}

		$type = strtolower( $graphData['@type'] );
		switch ( $type ) {
			case 'article':
			case 'blogposting':
			case 'newsarticle':
				unset( $schema[ $index ]['datePublished'] );
				unset( $schema[ $index ]['dateModified'] );
				break;
			default:
				break;
		}
	}

	return $schema;
}
