What is Facebook Pixel

Meta Pixel (formerly Facebook Pixel) is a measurement tool for tracking conversions and retargeting on Facebook and Instagram. It allows you to measure ad effectiveness, create custom audiences and optimise advertising campaigns.

Cookie Category

Facebook Pixel belongs to the marketing category.

Installation with Consentio

Add the Facebook Pixel code with type="text/plain" and data-category="marketing" attributes. The Consentio script will activate the pixel only after marketing cookie consent is granted.

<!-- Facebook Pixel -->
<script type="text/plain" data-category="marketing">
  !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', 'YOUR_PIXEL_ID');
  fbq('track', 'PageView');
</script>

<!-- Noscript fallback -->
<noscript>
  <img height="1" width="1" style="display:none"
    src="https://www.facebook.com/tr?id=YOUR_PIXEL_ID&ev=PageView&noscript=1" />
</noscript>

JavaScript API Alternative

Dynamically load Facebook Pixel after consent is granted:

Consentio.onConsentChange((consent) => {
  if (consent.marketing) {
    !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', 'YOUR_PIXEL_ID');
    fbq('track', 'PageView');
  }
})

Integration via GTM

If you use Google Tag Manager, set the Facebook Pixel tag to require ad_storage consent. Consentio automatically communicates with GTM via Google Consent Mode v2, so the tag will only fire after marketing consent is granted.

1. In GTM, create a new tag of type Custom HTML with the Facebook Pixel code
2. In the tag settings, go to Consent Settings
3. Set Require additional consent for tag to fire: ad_storage
4. Set the trigger to All Pages

Google Consent Mode v2

Consentio automatically maps categories to Google Consent Mode v2 signals:

Verification

1. Install the Meta Pixel Helper extension in Chrome
2. Before granting consent: the pixel should not send any events
3. After granting marketing consent: the pixel should send a PageView event
4. Verify in Meta Business Suite → Events Manager that events are being recorded correctly
