# Advertiser mapping

## How brands map to DSP advertisers

When you connect a DSP, Concord automatically creates one brand per advertiser. The brand name is pulled directly from the advertiser name in your DSP.

All brand creation and mapping is handled by Concord — there are no manual fields to configure.

## Changing advertiser assignments

To change which DSP advertiser is linked to a brand, ask Concord directly from the brand page:

```
"Reassign this brand to the Nike Running advertiser in DV360."
```

```
"Link the Meta ad account for Nike EMEA to this brand."
```

## Merging or splitting brands

If your DSP structure has multiple advertisers that represent the same business entity, ask Concord to consolidate them:

```
"Merge the Nike Running and Nike Trail advertisers under a single brand."
```

For more complex restructuring, contact your account manager.

## Missing or duplicate brands

**Campaigns not appearing under the right brand:**

```
"Why aren't my DV360 campaigns for Adidas showing under the Adidas brand?"
```

**Duplicate brands for the same advertiser:**
Contact your account manager to consolidate duplicates, as these typically originate from duplicate advertiser structures in your DSP.

<Note>
  Any changes to brand-advertiser mappings take effect after the next DSP sync.
