Installing Personizely means adding its snippet to every page of your store or site, and, on supported platforms, connecting the platform so Personizely can read products, carts and orders. On Shopify, Wix, Webflow and Square the app adds the snippet for you. On other sites you paste one script tag into the `<head>`.

The snippet is the same on every platform: one lightweight, per-site script served from a CDN. Platform integrations add store data on top of it, such as products, cart contents, customer data and server-side orders. That's what enables Shopify-only campaign types (theme, template, price and shipping tests) and cart and order-history targeting.

## Before you start

- **Create an account and a website.** Each website in Personizely has its own snippet, settings and reports. On Shopify and Wix, installing the app creates or connects the website for you. To run Personizely on several domains, see [Multiple websites](docId\:xTmxPcoGPGtWkYgcZd69E).
- **Decide how the snippet loads.** Asynchronous loading is the default and never delays your page. If you plan to A/B test page content, synchronous loading prevents the original from flashing before the variation. Read [Performance and flicker](docId\:sgD1BsYNMvpjqHqp_qcdi); you can change this later in **Settings → Tracking**.
- **Install once.** Use one method per site. If the snippet ends up on a page twice, only the first copy runs, but remove the extra one to keep things clear.
- **Content Security Policy.** If your site sends a CSP header, allow Personizely's hosts first. See [Content Security Policy (CSP)](docId\:kHb2SYuGO9A2ulTVoNa_J).
- **Consent.** See [Cookies and consent](docId:-HA6dgPmpYmb7x6UZQ_t2) for the cookie Personizely sets and how consent is handled on each platform.

## Verify it works

Whatever the platform, the same checks apply:

1. Open your site in a normal browser window (not a tag-manager preview or a speed-test tool) and open the developer console. You should see `Personizely initialized. Startup time: <n>ms`.
2. In Personizely, open the **Dashboard**. The **Snippet** card shows the install status and whether tracking is active.
3. For a step-by-step check and fixes for common problems, see [Verify and troubleshoot your installation](docId\:fM8b-wlEZqwZo2lSY7r4i).
