We want users to trust that information about them will be respected and handled with appropriate care. As such, our advertising partners should not misuse this information, nor collect it for unclear purposes or without appropriate disclosures or security measures.

Note that additional policies apply when using personalized advertising, which includes remarketing and custom audiences. If you use personalized advertising targeting features, be sure to review the personalized ads data collection and use policies.

Below are some examples of what to avoid in your ads. Learn about what happens if you violate our policies.

Violations of the policies below will not lead to immediate account suspension without prior warning. A warning will be issued, at least 7 days, prior to any suspension of your account. Learn more about suspended accounts.

Inadequate data security

The following is not allowed:

Failing to use appropriate security measures for the type of information being collected based on relevant industry standards

Examples (non-exhaustive): Collecting numbers for credit or debit cards, bank and investment accounts, wire transfers, national identity, tax ID, pension, healthcare, driver's license, or social security numbers over an unsecured page that is not SSL (Secure Sockets Layer) protected and without a valid SSL certificate

Troubleshooter: Inadequate data security
  1. Fix the ad's destination. Either stop collecting personal information from users or collect that personal information through a secure SSL server to keep it safe.
    • Option 1: Use a secure server.
      Use a secure processing server (called SSL) when collecting personal information. With SSL, your webpage URL will appear with https:// instead of http://. Learn how to set up SSL on your site.
    • Option 2: Don't collect user data.
      Change your website or app so that it doesn't ask for personal information when users access your content.
  2. Edit the ad. This will resubmit the ad and its destination for review.

    Most ads are reviewed within 1 business day, though some can take longer if they need a more complex review.

Unacceptable information sharing

The following is not allowed:

Sharing personally identifiable information (PII) with Google through remarketing tags, conversion tracking tags, or through any product data feeds that might be associated with ads

Example (non-exhaustive): Sharing user’s email addresses through URLs that have remarketing tags

Note: This requirement does not apply to Google Ads services subject to the Google Ads Data Processing Terms. (Enhanced Conversions, Google Ads Customer Match, Google Ads Store sales, Google Ads Store sales (direct upload))

Troubleshooter: Unacceptable information sharing
  1. Identify the source. Use the breach notice email provided by Google to identify which URLs are violating the policy. Frequently, PII is accidentally included in URLs that are passed to Google from web forms, login pages, and custom email marketing campaign parameters.
  2. Remove PII in shared data. Update your systems so that PII is not included in URLs. Below are the most common methods for removing PII from URLs.

    Web forms: HTML forms should be submitted with the POST protocol. If the GET protocol is used, the parameters of the form will end up as part of the URL in the address bar. Update the page source or the component generating the HTML so the form tag has method=”post” in the attribute. Learn more about the form method.

    Login pages: Some sites, especially those with user profiles or user login, use URL patterns that include PII as part of the design. Replace the PII in the URL with a unique site-specific identifier or a unique user ID (UUID).

    Custom email marketing campaign parameters: Examine the URLs generated by a test email marketing campaign to identify email addresses or other PII in URL parameters. Assign each user a unique site-specific identifier or a unique user ID (UUID) and track the UUID through URL parameters.

    You can implement a UUID to prevent PII from passing to Google. For example, could be changed to, where 43231 is a number that uniquely identifies the account with address
  3. Fill out the response form. Use the form to indicate that you have taken steps to fix the issue. The form helps Google know where you are in the process.
  4. Verify the problem is fixed. After you respond through the form, Google will validate that the changes you made to your site addressed the issue. Within two weeks, you’ll receive another notice to confirm that the issue is fixed or let you know if PII is still being shared from URLs associated with your account. If PII is still detected, examine the updated list of URLs that don’t comply with the policy to determine the cause of the issue.

    Note that you can verify that your changes work on a test site before pushing code changes to your live site. Tag your test site with tags from the same Google Ads customer ID that you use for personalized advertising. Once your test site shows up in the list of URLs where PII was detected, you can make test changes. If we stop detecting PII from your test site, it will drop off reports. Then you can push changes to your live site.

Remarketing lists and other lists based on remarketing, such as custom combination lists or similar audiences, will be disabled if they don’t comply with this policy. Learn more about what happens if you violate our policies.
