Google announced a new AdWords extension that allows you to ad third-party reviews dynamically into your ad copy of your AdWords ads.
Google said you can submit these reviews through the new AdWords reviews extension but they need to follow these guidelines:
- Content displayed in review extensions must come from a reputable 3rd party source, and must comply with standard AdWords policies.
- It’s your responsibility to ensure that you’re allowed to use a specific review in your ads.
- To protect users and other businesses from deceptive claims, we use automated and human-based systems to confirm the validity and policy compliance of all review extensions.
