## UTM attribution overview

This guide explains What is the difference between all the handl params? - HandL UTM Grabber Guide. It helps you capture UTM source, medium, campaign, term, content, click IDs, referrer, and landing page data and keep the marketing context needed for accurate reporting across forms, bookings, signups, and sales.

```
[handl_original_ref] - original referral - first touch!
[handl_landing_page] - landing page - first touch!
[handl_ref] - last touch referral
[handl_url] - last touch url
```

Let's say you have a link to your website from google.com to domain.com/page1
And user click from Google, he/she lands on page1 and after that they go to page2 to convert

So it is like Google -> Page1 -> Page2 (Conversion)

The params will populate the following data:

handl_original_ref = Google.com
handl_landing_page = domain.com/page1

handl_ref = domain.com/page1
handl_url = domain.com/page2
