hreflang Tags for Regional Versions of Your Site
Links matching pages across your country sites (such as example.com, example.co.uk and example.com.au) with hreflang tags, assuming each page uses the same path on every domain.

// Language-region code => site address (no trailing slash). x-default is used for everyone else.
$wpide_regional_sites = array(
'en-US' => 'https://example.com',
'en-GB' => 'https://example.co.uk',
'en-AU' => 'https://example.com.au',
'x-default' => 'https://example.com',
);
add_action( 'wp_head', function () use ( $wpide_regional_sites ) {

return;
}
$path = (string) wp_parse_url( home_url( add_query_arg( array() ) ), PHP_URL_PATH );
$base = (string) wp_parse_url( home_url( '/' ), PHP_URL_PATH );
$path = '/' . ltrim( substr( $path, strlen( rtrim( $base, '/' ) ) ), '/' );
foreach ( $wpide_regional_sites as $lang => $site ) {
printf( '<link rel="alternate" hreflang="%1$s" href="%2$s">' . "\n", esc_attr( $lang ), esc_url( untrailingslashit( $site ) . $path ) );
}
} );Notes
Add this to every regional site with the same map. Pages whose path differs between sites need a multilingual plugin instead.
