## UTM tagging best practices

Adding a `utm_id` parameter to your tagging template will guarantee improved stitching quality of costs to sessions without altering the rest of your existing UTM tags.

We suggest using the following format for the `utm_id` parameter in Display & Video 360 ads:

```plain text theme={null}
utm_id={ID of the campaign}_{ID of the line item}
```

The tagging can be implemented using [URL macros](https://support.google.com/displayvideo/answer/2789508?hl=en).

## UTM matching for Youtube & partners ads

SegmentStream does not support automatic UTM matching for [Youtube & partners ads](https://support.google.com/displayvideo/answer/6274216?hl=en).

You can define the default `utm_source` and `utm_medium` for all these ads through the **UTM source for YouTube & partners ads** and **UTM medium for YouTube & partners ads** settings. SegmentStream will use the campaign name of those ads to match by `utm_campaign`.

The following setup will help improve cost data stitching and will allow seeing costs at campaign level for Youtube & partners ads:

```plain text theme={null}
utm_source=youtube&utm_medium=cpm&utm_campaign={campaign name in the DV360 interface}
```
