Begining May 17th, Google will be adding three requirements to existing AdWords policies that cover disclosure and usage of personal information applicable to everywhere AdWords is available.
If your site requests payment, financial, or personal information from visitors, please review the new requirements and make any needed changes to avoid having your ads suspended.
- Clear, accessible disclosure before visitors submit personal information
Our existing policy requires you to clearly describe how any personal information you solicit will be used. Soon, we'll require that your description must also be easily accessible before site visitors submit their details.
- Option to discontinue direct communications
In the same description of how personal information will be used, you'll also be required to describe how people can opt out of future emails, phone calls, or other direct communications.
- SSL when collecting payment and certain financial and personal information
Many websites use what're known as Secure Sockets Layer (SSL) connections to encrypt sensitive information that travels between the user's browser and the website's servers. To help ensure user safety, AdWords policy will require all advertisers to use SSL when collecting payments and certain financial and personal information (like bank account and social security numbers).
