# Ignore Tracking Parameters When Matching Redirects

> Strips utm_*, fbclid, gclid and similar tracking parameters from the URL the Redirection plugin matches against, so a redirect still fires when a link arrives from a campaign.

## Code

```php
$wpide_params = array( 'utm_source', 'utm_medium', 'utm_campaign', 'utm_term', 'utm_content', 'fbclid', 'gclid', 'msclkid', 'mc_cid', 'mc_eid' );

add_filter( 'redirection_request_url', function ( $url ) use ( $wpide_params ) {
    return is_string( $url ) && false !== strpos( $url, '?' ) ? remove_query_arg( $wpide_params, $url ) : $url;
} );
```

## Notes

Add parameters to $wpide_params. The visitor's analytics are unaffected because the original URL is only changed for matching.
