The Google Blog formally announced the new search ad formats Google has been showing in the search results. The new ads include the relatively old AdWords video ad, AdWords Sitelinks, local AdWords, product AdWords, comparison ads and more.
The product ads are now available to all U.S. advertisers. Here is how to get started: First, log in to Google Merchant Center and add your Adwords customer ID to your account. Then, simply visit the campaign settings tab in your AdWords account, find the ‘Ad extensions’ heading and select the option to “Use product images and information from my Google Merchant Center account.” No need to create new campaigns or ad groups, update your keywords or change your ad text.
