Google Product Feed for PPC

As mentioned in a post on January 8th, you must have a Google Merchant Center in order to implement a product feed file to push product images out to your AdWords text ads.  Once your XML file is active, you must do two things to make this works for PPC: 

• link each AdWords Campaign to the Merchant Center Account from the Campaign Settings tab, AND
• link the Merchant Center to the AdWords Account from the Merchant Center Settings tab

Once your AdWords Campaigns are properly synched to your Merchant Account, it may take 24-48 hours before Google serves your ads with Product Extensions.

Note:  Ad Extensions are currently only enabled for US advertisers
