# Tracking best practices

Combining UTM parameters and the Channel ID (`cid`) parameter ensures that deep link tracking remains consistent, readable, and actionable across different touchpoints.

## Recommended tracking logic

When generating deep links, apply parameters with a clear separation of concerns:

- **UTM parameters:** Describe the traffic source and context.
- **CID:** Identifies the commercial touchpoint or sales channel.


| Parameter | Recommended value | Purpose |
|  --- | --- | --- |
| `utm_source` | `{{company_name}}-{{touchpoint}}` | Identifies where the link is shown (e.g., `Manage-Booking`). |
| `utm_medium` | `{{channel}}` | The delivery method (e.g., `web`, `app`, `email`). |
| `utm_campaign` | `{{campaign-context}}` | Describes the content or context the user sees. |
| `cid` | `{{touchpoint}}_{{booking-reference}}` | Identifies the sales channel; appending a booking reference helps verify purchase timeframes. |


## Practical examples

**Manage My Booking (web)**

A link promoting activities for a specific destination within a customer's online booking portal:


```
{baseUrl}/paris?utm_source=company-Manage-Booking&utm_medium=web&utm_campaign=Destination-Paris&cid=manage-booking_XY1234
```

**Booking confirmation email**

A link included in a post-purchase email to explore local experiences:


```
{baseUrl}?utm_source=company-Confirmation-Email&utm_medium=email&utm_campaign=Things-To-Do&cid=confirmation-email_AB5678
```
