Facebook Pixel ID 加進 Google Tag Manager 有兩個方法，第一個是下面 Facebook 教學的，直接用 Custom Code 方式加進去，這個在 Facebook 教學裡可以看到，也應該是最簡單的。即把這種 Pixel Code 直接加進去：
<!– 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’, ‘9999999999999999‘); fbq(‘track’, ‘PageView’); </script> <noscript><img height=”1″ width=”1″ style=”display:none” src=”https://www.facebook.com/tr?id=9999999999999999&ev=PageView&noscript=1″/> </noscript> <!– End Facebook Pixel Code –>

非官方教學方法，用別人的 Template
至於石先生用的是這篇的方法，用別人的 Template 去做，教學其實下面連結的網有寫，但還是怕那天這個頁面沒了，Copy 下來留個底，大家還是去原文網址看吧！因為有些說明細節要原文網址才有說，以下僅有步驟。如果不求原因就按步驟做了，其實不是一件好事。
