# Reddit Ads: Insert the UTMs

## Step 2: Add the Northbeam tracking parameter

The Northbeam tracking parameter must be added to the **Destination URL** for every Reddit ad.

Use the following parameter:

```text theme={null}
?nbt=nb:reddit_ads:reddit_ads:{{CAMPAIGN_ID}}:{{ADGROUP_ID}}:{{AD_ID}}
```

Reddit automatically replaces the template values with the campaign, ad group, and ad identifiers when the ad is served.

### Add the parameter to an ad

1. Sign in to [Reddit Ads Manager](https://ads.reddit.com/).
2. Open the campaign that you want to update.
3. Open the relevant ad group.
4. Select the individual ad.
5. Find the **Destination URL** field.
6. Add the Northbeam tracking parameter to the destination URL.
7. Review the destination URL and click **Save**.

<Info>
  ### Ad-level requirement

  Add the parameter to every individual ad. Adding it only at the campaign or ad group level does not meet the Reddit Ads tracking requirement.
</Info>

### Use the correct URL separator

If the destination URL does not already contain query parameters, add `?` before the Northbeam parameter:

```text theme={null}
https://www.example.com/product?nbt=nb:reddit_ads:reddit_ads:{{CAMPAIGN_ID}}:{{ADGROUP_ID}}:{{AD_ID}}
```

If the destination URL already contains a `?` and other query parameters, add the Northbeam parameter using `&`:

```text theme={null}
https://www.example.com/product?utm_source=reddit&utm_medium=paid&nbt=nb:reddit_ads:reddit_ads:{{CAMPAIGN_ID}}:{{ADGROUP_ID}}:{{AD_ID}}
```

<Info>
  ### Copy the parameter exactly

  Missing colons, underscores, braces, or identifiers can prevent Northbeam from reconciling visits correctly.
