# About the URL Structure of Site Pages

Understanding the URL structure of Wix site pages is crucial for tasks such as routing, linking, SEO, and query parameter manipulation.

## Sample URLs

The structure of the URLs differ between Wix premium sites and Wix free sites:

- **Premium sites**: Use a custom domain, such as `domain.com`:
 `https://domain.com/animals/mammals/elephant?species=african-elephant`.

- **Free sites**: Reflect the Wix editor as the domain followed by the site name, such as `user.wixstudio.io/zoo` for Wix Studio sites and `user.wixsite.com/zoo` for Wix Editor sites.

    - **Wix Studio**: `https://user.wixstudio.io/zoo/animals/mammals/elephant?species=african-elephant`

    - **Wix Editor**: `https://user.wixsite.com/zoo/animals/mammals/elephant?species=african-elephant`

You can get the full site URL, as well as its parts, using the [Wix Location Frontend API](https://dev.wix.com/docs/velo/api-reference/wix-location-frontend/url.md).

## Key parts of a URL

| Term        | Description                                                                                                                                         | Example                              |
|-------------|-----------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------|
| **Protocol**| Standard part of the URL that indicates the protocol used to access the resource.                                                                     | `https://`                           |
| **Base URL**| Represents the root domain of your site. Premium sites use a custom domain, while free Wix sites include the editor followed by the site name.                                                                                                               | Premium: `domain.com`<br>Free (Wix Studio): `user.wixstudio.io`<br>Free (Wix Editor): `user.wixsite.com` |
| **Prefix**  | Component used for dynamic paths and router pages. Prefixes are useful for [making Dynamic Page URLs](https://dev.wix.com/docs/develop-websites/articles/databases/wix-data/dynamic-pages/making-dynamic-page-urls-meaningful-with-prefixes.md), or for determining which incoming requests the [router](https://dev.wix.com/docs/develop-websites/articles/coding-with-velo/routers/about-routers.md) handles.                                            | `/animals`                           |
| **Path**    | The path typically follows the base URL or the prefix, if a prefix exists. For dynamic pages and router cases, paths are used for structure or to encode information to indicate what dynamic content to show. | `/mammals/elephant`                  |
| **Query**   | Query parameters are key-value pairs appended to the URL to pass additional data.                                                                   | `?species=african-elephant`          |
