What is the Facebook Pixel and do I actually need it?

Short answer

Tracking code from Meta that reports what visitors do on your pages back to your ad account. systeme.io's setup guide requires a Facebook ad account, so it is for people running Meta ads.

What it is

A piece of code created in Facebook, not in systeme.io. The snippet comes out of Events Manager: click your pixel, choose Set up Meta Pixel, then Install Code Manually.

It watches the browser. The Facebook Conversions API is the same idea done through the server instead, tracking what Meta calls server events.

Where it goes

  • Into one page's header code box: open the page editor, click Settings, scroll to the Tracking section, then Edit header code.
  • Or into the tracking code field at Settings, then Sales funnels, which pushes it out across every funnel automatically.

systeme.io is explicit that the pixel code belongs on all the pages of a funnel, not only the one people land on.

What the guide asks for before you begin

Four things: a Facebook business account, a Facebook ad account, a systeme.io account, and a custom domain.

Domain verification is part of it. Meta gives you a meta tag, and that goes in the same header code box or the funnel settings, below the pixel code, with a line break between the two.

Do I actually need it?

If you do not run Meta ads, no. A Facebook ad account is one of the four things the guide asks for before you start.

If you do run them, the pixel is the reporting line. The Conversions API is the server-side version, set per domain at Settings, Custom Domains, the three dots beside your domain, then Settings, where you paste a pixel ID and an access token.

Running both without counting twice

When the same event goes out through the browser and the server, Meta merges the pair using an event ID. The ID travels automatically on the Conversions API side. On the pixel side you add a placeholder to the tracking code, which systeme.io replaces with the real identifier at the moment of conversion.

What it will not split apart

The whole order value goes out at the moment of purchase, upsells included. The Conversions API on the thank you page picks up the main offer, the order bumps and the upsells together in one event.

So an order bump does not report as its own sale.
