Paste the Cuttl Tag into Code injection once, and it goes on every post and page.

Where the Cuttl Tag goes: Settings, Code injection, Site header.

## Add Cuttl to Ghost

1. Sign in to Cuttl, or create a free account. Add your site with its domain. Open the site’s Install tab and copy the Cuttl Tag. It starts with <!-- Start Cuttl -->.
2. In Ghost Admin, open Settings (the gear icon) and go to Code injection.
3. Paste the Cuttl Tag into Site header.
4. Click Save.
5. In Cuttl, turn on Journey Insights for heatmaps and recordings, or Web Experiments for A/B tests. Admins can do it on the product’s page or in Settings → Plan & usage. A new workspace starts with both off, and until one is on, Cuttl keeps nothing from your site.

You need the Administrator or Owner role.

## Check it works

1. Open any page of your live site in a browser.
2. In Cuttl, open the site’s Install tab. It shows when data last arrived, usually within a minute.
3. Nothing yet? View the live page’s source and search for app.cuttl.io to check the Cuttl Tag is there. Then check that the site’s domain in Cuttl matches the address in your browser.

## Good to know

- Ghost adds the site header code through {{ghost_head}}, which every Ghost theme includes. Switching themes keeps the Cuttl Tag.
- To see which posts lead to sign-ups, add a goal in Cuttl for your sign-up or subscribe button.
- To leave out your own sessions, open any page of your site once with ?cuttl_ignore=1 at the end of the address.

## Ghost questions

### Does it work on Ghost(Pro) and self-hosted Ghost?

Yes, wherever Ghost Admin shows Settings → Code injection.

### Can I A/B test a headline or sign-up box?

Yes. Change text, buttons or layout in the visual editor, and Cuttl shows which version gets more sign-ups.

### Will it slow my site down?

No. The Cuttl Tag is under 1.7 KB and loads the rest in the background, so it never blocks the page.

Free for one site. Add the Cuttl Tag, turn on Journey Insights, and your first sessions show up in Cuttl.
