# How to override the preview URL?

In certain cases, you might want to display a preview of a different URL than the one actually linked. This can be useful if, for example, you have a middle page that users pass through before visiting a third-party link (similar to the approach used by LinkedIn or Facebook).

To achieve this, you can use the `data-linkz-preview-url` attribute within your HTML anchor tags. By setting this attribute, you can specify a custom URL for the preview, independent of the hyperlink itself.

**Example**

Here’s how you can use the `data-linkz-preview-url` attribute:

```html
<a href="https://your-domain.com/going-external" data-linkz-preview-url="https://example.com/previewed-url">Example hyperlink</a>
```

In this example:
* `href="https://your-domain.com/going-external"`: The actual link where the user will be directed when they click the hyperlink.
* `data-linkz-preview-url="https://example.com/previewed-url"`: The URL that will be used to generate the preview.

This setup ensures that users see a preview of `https://example.com/previewed-url` when hovering over or interacting with the link, even though they will ultimately be directed to `https://your-domain.com/going-external`.

**Use Case**

This feature is particularly useful for sites that include a transition page before redirecting users to an external link. It allows you to maintain consistent preview behavior, even when the actual link is different from the content being previewed.
