In order for Google ad data to populate in Ads Data Hub, the Google ad platform accounts managing the data must be linked to the Ads Data Hub account. Account linking requests originate in the ad platform and are sent to Ads Data Hub. The owner of the account can be different (as in the case of an advertiser providing access to a vendor), or the same (as in the case of a single advertiser).

Data begins populating in Ads Data Hub after the link is approved.
Note: When a *new* Ads Data Hub account is created, any customer ID linked to that account within the first 7 days automatically receives up to 21 days of historical data backfilled. This data prefill is meant to let you begin executing queries without waiting for data to accumulate to meet privacy and aggregation thresholds.

The basic process for linking accounts is as follows. Note that these steps
might be performed by different users, such as in the case of a data-owner
granting a vendor access to their ad data:

1. Initiate a link request from the Google ad platforms you want to link.
2. Approve the link using either the Ads Data Hub UI or API.

## Self-service linking

> [!NOTE]
> **Note:** Each advertising account linked to an agency account exports isolated data. For example, if an advertiser owning two Google Ads accounts links them both to one agency's Ads Data Hub account, the agency can analyze the data from each ad account separately, but not query across them.

### YouTube Reservation

**Traditional Reserve buys (Connect Reserve):** Use these steps if you did not
provide a Google Ads customer ID when setting up your campaigns, and you did not
buy your YouTube Reserve campaigns in Google Ads.

1. Contact your Google sales representative to work with a Brand Specialist.
2. Provide the insertion order ID of your YouTube Reservation campaign.

Once the data is available in Ads Data Hub, you can query it in the
`adh.yt_reserve_*` tables.

**Consolidated Reserve buys (Instant Reserve):** Use these steps if you provided
a Google Ads customer ID when setting up your campaigns, or you bought your
YouTube Reserve campaigns directly in Google Ads.

YouTube Reservation that is integrated with Google Ads must be linked using the
Google Ads account. See [Link your Google Ads
account](https://developers.google.com/ads-data-hub/marketers/guides/link-accounts#link_your_google_ads_account). If you have already linked the Google
Ads account that contains your YouTube Reservation data, no further action is
required.

Once the data is available in Ads Data Hub, you can query it in the
`adh.google_ads_*` tables. You can differentiate between Connect Reserve and
Instant Reserve campaigns by using `adh.google_ads_campaign.reservation_type`.

If you are an advertiser or an agency, contact your publisher.
If you are publisher, refer to [these instructions](https://support.google.com/yt-partner-sales/answer/9712149). (Note that you must be a YouTube partner with sales rights on YouTube to access the article.)
