Link a Merchant Center Account to DoubleClick Search and AdWords
Google Merchant Center helps you upload your store and product data to Google and make it available to Google services. If you've set up a Merchant Center account, link it with DoubleClick Search (DS) to create and manage the following types of campaigns:
- Inventory keyword campaigns
- Shopping campaigns. Note that Shopping campaigns require you to link a Merchant Center account with both DS and AdWords.
Important details about linking accounts
Each campaign associates with one account
Each campaign can advertise products from only one Merchant Center account. Depending on how you structure your campaigns and inventory accounts, you can do either of the following:
- Link one Merchant Center account for each campaign
- Link one Merchant Center account, and then create campaigns that advertise only specific products in the account
Multi-client accounts and subaccounts
If you have a multi-client account Merchant Center account (also known as a parent or umbrella account), you can link to the multi-client account and DS will automatically link to all subaccounts. Campaigns that you associate with a multi-client account can advertise products in any of the subaccounts. You can use filtering in the campaign settings to limit the set of products the campaign can advertise.
If you've already linked a subaccount to DS and later you link the parent multi-client account:
DS treats the subaccount and the multi-client account as separate accounts. For example, if you unlink the subaccount, the multi-client account remains linked and continues to sync in data from the subaccount.
- You can associate a campaign directly with the subaccount or with the multi-client account.
- If a campaign is associated with the subaccount and you remove the subaccount, the campaign will stop generating and updating ads and keywords. You'll also see an error to let you know the campaign is no longer linked to an inventory account.
If you use Shopping campaigns, the Merchant Center account you link to in DoubleClick Search must exactly match the account you link to in AdWords. For example, if you link to a multi-client account DS, you need to link to the multi-client account in AdWords. If instead you linked to a multi-client account in DS but linked to individual subaccounts in AdWords, your Shopping campaign would not be able to access inventory data. Note that in DS, you can link to both a multi-client account and all of its subaccounts if needed. DS will not duplicate the inventory data.
AdWords also provides the ability to link campaigns to inventory accounts. If you sign into AdWords and link a campaign to a subaccount while only the parent multi-client account is linked in DS, DS will not recognize the link you set up in AdWords. In DS, you may see a message similar to the following:Some product groups may not serve. Please make sure Google Merchant Center account (account ID:xxx) is added as its own DS inventory feed and is linked to AdWords account (CID:xxx)
If you see this notification, manually link the subaccount to DS. The additional link won't impact the multi-client account or any other campaigns.
No support for "Online Product Inventory Update" feeds
When you register your data feed for a Merchant Center account, you can set up a full "Product" feed or an "Online Product Inventory Update" feed, which simply updates information for items already submitted through another account in a full "Products" feed.
DS requires all linked accounts to provide full "Products" feeds, and will ignore any data submitted from "Online Product Inventory Update" feeds.
How often does DS pull in feed updates?
Multiple times throughout the day, DS checks with Google Merchant Center for any updates to your inventory account. The Feed last update time column on the Inventory accounts tab tells the most recent time that DS successfully loaded updates from a feed. A lag of more than 24 hours could indicate a problem with DS.
Link a Merchant Center account with DS
To link with Merchant Center, your user account needs all of the following permissions:
If no one in your organization has the correct permissions, contact customer support. Please include both your DS advertiser ID and the Merchant Center account ID that you would like to link.
Link Merchant Center
After signing into Google with an account that has the appropriate permissions:
- In DS, navigate to an advertiser.
- In the left navigation panel, click Inventory Management.
- Click + Inventory account and enter the following information:
- Account name: This name appears only in DS. You use the name when associating the account with a campaign, when pausing the account, or when viewing the product data DS has for the account.
- Notification emails: An optional list of email addresses that will be notified when an adaptive Shopping campaign divides a product group, or when an inventory keyword campaign creates ad groups. You can override this list of emails when you set up each adaptive Shopping campaign or inventory keyword campaign.
- Google Merchant Center Account: The account list contains all Merchant Center accounts for which you have Admin access. Select an account to link it to DS.
- Click Validate.
If DS doesn't respond after you click Validate, someone may have already linked to the Merchant Center account before, but then the account was subsequently removed from DS. Here's how to resolve this issue:
Scroll to the top of the Inventory account edit panel. In the Show list above the reporting table, select Show all.
If the Merchant Center account appears with (removed icon) next to its name, the account has already been added but subsequently removed.
If the account was removed by mistake, click (removed icon) and select Active.
Then click Validate again.
If validation succeeds, click Save.
To ensure that the Shopping campaigns you manage in DS will work correctly, DS checks that your Google Merchant Center and AdWords accounts are linked. If they’re not:
Ads from existing Shopping campaigns DS will not appear on Google.
You won’t be able to create new Shopping campaigns in DS.
You won’t be able to sync in changes to Shopping campaigns.
To link your Merchant Center account with AdWords:
Sign in to your Google Merchant Center account at https://merchants.google.com.
In the left nav, navigate to Settings > AdWords.
In the AdWords Customer ID field, enter the AdWords account’s customer ID (in the fomat xxx-xxx-xxxx).
Click Link Account.
