# Add Privatus Analytics to Turbo and Hotwire

> Add cookieless analytics to an app that uses Turbo Drive, Hotwire or Turbolinks with one script tag in the head that counts each visit once.

Add the snippet to your layout's `<head>`, not the body:

```html
<script defer src="https://privatusstats.com/js/pa.js" data-site="pa_YOURSITEID" data-modules="engage,auto,vitals,clicks,ask"></script>
```

Turbo Drive checks the `<head>` of each new page for scripts that are not on
the current page and appends only those. The tracker is already there, so it
loads once and keeps running across visits.

Turbo Drive changes pages with `history.pushState`, and the tracker follows
that by default (`data-spa="auto"`). Each visit counts as one page view and
you don't need a `turbo:load` listener. Counting from both would give
double views, so don't also send pageviews yourself. See
[single-page apps](/docs/tracker/spa).

## Notes

* Don't add `data-turbo-track` to this tag. That attribute is for your own
  bundles, to force a reload when a new build ships.
* Turbolinks, the older library, also uses `pushState`, and the same tag works.
* For Rails, see the [Rails page](/docs/install/rails). Frames and streams
  that change part of a page are not page views.
