# Add Privatus Analytics to Hugo

> Add cookieless analytics to a Hugo site with a head partial that loads the tracker only in production builds, and keep your site id in the Hugo config.

Create (or edit) a partial your theme includes in `<head>`, for example
`layouts/partials/extend_head.html` or `layouts/partials/head.html`:

```go-html-template
{{ if hugo.IsProduction }}
  <script defer src="https://privatusanalytics.com/js/pa.js" data-site="pa_YOURSITEID"></script>
{{ end }}
```

`hugo.IsProduction` is true for `hugo` builds and false for `hugo server`,
so local previews aren't counted.

Keep the site id in your config instead:

```toml
# hugo.toml
[params]
  privatusSite = "pa_YOURSITEID"
```

```go-html-template
{{ with site.Params.privatusSite }}
  <script defer src="https://privatusanalytics.com/js/pa.js" data-site="{{ . }}"></script>
{{ end }}
```
