The remarketing or similar audiences feature in AdWords allows you to reach people who previously visited your website, and match the right people with the right message. While remarketing can be a great way to attract past visitors back to your site, you should inform these people that you gather information for remarketing or similar audiences on your website.
- An appropriate description of how you're using remarketing or similar audiences to advertise online.
- A message about how third-party vendors, including Google, show your ads on sites across the Internet.
