Tracking connects your custom to the tools you already measure in, so the people
coming through show up there as well as here.

Three platforms are supported: **Google Tag Manager**, the **Meta Pixel** and the
**TikTok Pixel**. You'll find them in the **Tracking** tab of any custom.

Tracking is only about sending events out to those tools. It isn't where you set
up webhooks — see [Automation](/en/customs/automation/) — and it isn't where you bring
people in — see [People](/en/customs/people/).

Each platform has its own page, and the first explains what is actually being
sent:

- **[How tracking works](/en/customs/tracking/how-tracking-works/)** — what
  reaches your tools, and why it arrives when browser tracking often doesn't.
- **[Set up Google Tag Manager](/en/customs/tracking/google-tag-manager/)** —
  connect a GTM container to your custom.
- **[Set up Meta Pixel](/en/customs/tracking/meta-pixel/)** — so Facebook and
  Instagram ads can optimise on completions.
- **[Set up TikTok Pixel](/en/customs/tracking/tiktok-pixel/)** — report
  completions back to TikTok Ads.
