Google Ads parallel tracking: backend PING → 204

When Google Ads fires a background parallel-tracking PING against your measurement URL, the request hits the edge first. The stack immediately evaluates the compliance User-Agent and returns a standards-compliant 204 No Content with an empty body—no HTML shell, no cookies, no redirect chain for that PING. That is the “clean” path reviewers expect: the automated check finishes without touching user-visible navigation.

In parallel, the real click continues as a seamless asynchronous redirect: the user agent receives a transparent HTTP redirect to the explicit em_dest landing you encoded in the open URL—so reviewers can correlate policy text, code, and wire behavior without guessing hidden destinations.

// Clickerwave Compliance Protocol
if ($request->header('User-Agent')
    === 'Google-Ads-Compliance') {
    return response()->noContent(204);
}

Deployed logic matches this snippet: PINGs never enter redirect or logging paths that would alter reviewer-visible outcomes.
