Create a shopping campaign
Sync an AdWords Shopping campaign into DoubleClick Search
If you've already created a Shopping campaign in AdWords, you can sync the campaign into DoubleClick Search (DS) and then manage and report on the campaign from DS.
Before you start
Before syncing an AdWords account that contains a Shopping campaign, make sure you to link DS to the same Merchant Center account that you've connected to AdWords. Be sure that the Merchant Center accounts connected to your AdWords account are exactly the same accounts that you link to DS.
If you accidentally sync a Shopping campaign before you link DS to your Merchant Center account (or if you link the wrong Merchant Center account with DS), link the correct Merchant Center account, then select Fix all trafficking errors in active accounts when you sync the campaign into DS.
Sync the campaign into DS
After linking your Merchant Center accounts, sync the AdWords engine account with DS.
