About Facebook pixel code

1. Pixel base code

• Go to the pixel page in Ads Manager.
• Click Actions > View Code.
• Copy the base code and paste it between the <head> tags on every page, or into the website template to install it across the site.

2. Event code

• Standard events
  1. Original website code: paste the Facebook pixel between <head> and </head>. If other code is already there, paste the pixel below it, above </head>.
  2. Facebook pixel base code: it is as shown in the illustration, except your pixel number will differ from 567845666.
  3. Standard event code: paste the code relevant to the page, such as Complete Registration or Add to Cart, above </script> in the pixel code. Do this on every page you want to track.
  4. 
• Custom events
  1. These track important business actions, but need additional setup for tracking and optimization. Learn how to use custom events.

Add Facebook pixel base code to website pages

1. Open the Facebook pixel tab in Ads Manager.
2. Click Actions > View Pixel Code.
3. Click the code to highlight it.
4. Right-click and Copy, or use Ctrl+C/Cmd+C.
5. Click Done.
6. Open the website HTML and paste the code.

Add event code to website pages

1. Open the Facebook pixel tab in Ads Manager.
2. Click Create Conversion > Track Conversions With Standard Events.
3. Copy the event code for important events.
4. Open the website code and replace the event code on the relevant pages. We recommend adding event code separately between script tags and leaving the pixel base code unchanged.

Final code to place on the page

		<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', '12345678900');
	    fbq('track', "PageView");
	    fbq('track', 'Lead');
	    </script>

	    <noscript><img height="1" width="1" style="display:none"
	    src="https://www.facebook.com/tr?id=12345678900&ev=PageView&noscript=1"
	    /></noscript>

1. fbq('init', '你的fbid'); — replace the placeholder with your Facebook ID.
2. fbq('track', "PageView"); — the pixel event type to count.
