# Add the script

> Paste the Datacenter script tag into your site's head. Steps for plain HTML, WordPress, Shopify, Webflow, Squarespace, Wix and single page apps.

Section: Start here

The script is one tag. In Private mode, the default, it sets no cookies and stores nothing in the browser.

```html
<script defer data-site="shop.example.com" src="https://datacenter.so/s.js"></script>
```

Put it in the `<head>` of every page. `data-site` is the domain you added in Datacenter.

## What the script does

- Counts a pageview once the tab has been visible for 1.5 seconds.
- Sends how long the page was visible when the visitor leaves.
- Follows page changes in single page apps that use the History API.
- Reads UTM tags and ad click ids (`gclid`, `gbraid`, `wbraid`, `fbclid`) from the landing address.
- Does nothing in automated browsers that report `navigator.webdriver`.
- Does nothing on `localhost` or `127.0.0.1`, so a test on your own computer adds no visit. Open the published site to see your first one.

## Plain HTML

Paste the tag inside `<head>` on each page, or in your shared header template.

## WordPress

Use the [Datacenter plugin](https://datacenter.so/docs/install-wordpress): upload it, press **Connect to Datacenter**, and approve. It adds the tag and counts WooCommerce orders and new accounts, with nothing to paste. To paste the tag yourself instead, use your theme's header settings or a plugin that adds code to the head, and clear any page cache after you save.

## Shopify

In the admin, open **Online Store**. Next to your theme, click **...**, then **Edit code**. Open `theme.liquid` and paste the tag just before `</head>`. [Full Shopify guide](https://datacenter.so/docs/install-shopify).

## Webflow, Squarespace and Wix

Each has a site wide setting for custom code in the head. Paste the tag there and publish the site. Some of these builders only allow custom code on paid plans.

## Single page apps

Load the tag once, in the main HTML file. The script listens for route changes and counts each one as a pageview. You do not need to call anything yourself.

## Check it

Open your site, wait a few seconds, then look at the **Live** count in your dashboard. The same browser counts as one visitor per day.

## Ad blockers

Some blockers stop analytics scripts by their address. To count those visits, serve the script from your own domain with a [script proxy](https://datacenter.so/docs/script-proxy).
