# Pass URL Parameters Across Links

> Pass URL parameters across all links to preserve tracking data, maintain attribution, and optimize campaign performance.

This feature allows you to automatically **forward URL parameters across all links on your page**.

It ensures that important tracking data (like UTM tags or affiliate IDs) is **not lost when users click to the next page**.

***

## What It Does

When enabled, any parameters in your page URL (for example:\
`?utm_source=facebook&utm_campaign=spring`) will be **automatically added to every link** on your page.

So instead of losing tracking data, it continues through the entire user journey.

***

## Where to Find It

1. Open your page in the editor
2. Click the **Actions / Quick Actions panel**
3. Locate **Pass Through URL Params**
4. Toggle it ON

## How It Works

If your page URL contains:

```text theme={null}
?utm_source=facebook&utm_campaign=test
```

And a button links to:

```text theme={null}
https://offer.com
```

It will automatically become:

```text theme={null}
https://offer.com?utm_source=facebook&utm_campaign=test
```

***

## Why It’s Important

* Keeps **tracking data consistent across pages**
* Essential for **affiliate marketing**
* Helps maintain **accurate campaign attribution**
* Prevents loss of **UTMs, click IDs, or custom parameters**

***

## When to Use It

* Running paid ads (Facebook, Google, TikTok, etc.)
* Using affiliate or tracking links
* Passing data to external pages or funnels
* Multi-step funnels where tracking must persist

***

## Important Notes

* Applies to **all redirect links on the page**
* Works automatically once enabled
* Does not require manual setup per button

***

## Best Practice

Always enable this when:

* You rely on tracking parameters
* You’re sending traffic to another page or offer
