I've added the following code (see below) to the head tag, but the code is still sending referrer into Facebook via the pixel - how can we fix this to not show referrer?
meta name="referrer" content="no-referrer"
code.php:
<!DOCTYPE html>
<html lang="en">
<head>
<meta name="referrer" content="no-referrer">
<!-- Facebook Pixel Code -->
<script>
!function(f,b,e,v,n,t,s)
{if(f.fbq)return;n=f.fbq=function(){n.callMethod?
n.callMethod.apply(n,arguments):n.queue.push(arguments)};
if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';
n.queue=[];t=b.createElement(e);t.async=!0;
t.src=v;s=b.getElementsByTagName(e)[0];
s.parentNode.insertBefore(t,s)}(window, document,'script',
'https://connect.facebook.net/en_US/fbevents.js');
fbq('init', '373193981057100');
fbq('track', 'PageView');
function fbLeadEvent() {
window._fbq.push('track', 'Purchase');
}
</script>
<!-- End Facebook Pixel Code -->
</head>
<body>
<a href="https://google.com" onclick="fbLeadEvent();">Link text here</a>
</body>
</html>
