# Obelism numbers (/docs)

Obelism numbers counts what happens on your sites: who visits, which pages they read, where they came from, what they click and the events you send yourself. Obelism Improve's tests and Content's pages send their events to it, so a test result, a page's click rate and the dashboard all count the same visitors.

## What it counts [#what-it-counts]

- **Visitors, sessions and page views** over time, with the bounce rate and the average session, against the range before.
- **Pages**: the most viewed paths. Query strings never leave the browser.
- **Sources and campaigns**: the referring site's host, and the UTM tags of the visit.
- **Countries, devices, browsers and operating systems.**
- **Clicks** on the elements you tag with `data-numbers-id`, with a click rate.
- **Events**: everything a site sends, by name and scope.

## How events get in [#how-events-get-in]

1. [The script](/docs/getting-started): one `<script>` tag, no bundler. It sends page views, also on client-side navigations, and clicks on tagged elements.
2. [The SDK](/docs/sdk), `@obelism/numbers-sdk`: the same client as an npm package, for apps with a bundler and for your own events. The Improve SDK sends through it, so a site with Improve already sends to numbers.
3. [Your server](/docs/api/log): `POST /api/log` with an API token.

## Where it lives [#where-it-lives]

numbers works per **Space** (one site or project of your Organization) and **environment** (`develop`, `staging` or `production`), like Improve and Content. Every member of an Organization that may open a Space sees its numbers at [numbers.obelism.studio/dashboard](https://numbers.obelism.studio/dashboard). Agents read the same reports through the [MCP server](/docs/agents).
