If you want to define a Google Analytics “UA String” while using Yoast Google Analytics plugin for WordPress.
Add the following to your theme’s `functions.php` file:
add_filter( 'option_Yoast_Google_Analytics', 'custom_ua_string_filter');
function custom_ua_string_filter($options = array()) {
$options['uastring'] = 'UA-########-#';
$options['manual_uastring'] = true;
return $options;
}
For users of WordPress Multisite, this will allow you to pre-configure new blogs with the same UA string.
