}

To resolve flagged custom conversions

If any of your custom conversions are flagged for suggesting information that is not allowed under our terms, you may want to consider the following options:

To resolve a flagged custom conversion in a new campaign creation:

Create new custom conversion: Use a new custom conversion and make sure that it does not include information that is not allowed under our terms.

Choose a different custom conversion: Select a different existing custom conversion and make sure it does not include information that is not allowed under our terms.

To resolve a flagged custom conversion in an existing campaign:

Duplicate your campaign and select an existing custom conversion: If you have a running campaign that is flagged due to a flagged custom conversion, consider duplicating the campaign and selecting a different custom conversion that is not flagged before publishing the new duplicated campaign. Note: Once the campaign is published, you cannot remove or select a different custom conversion.

Request a review

If you believe your custom conversion has been flagged in error and doesn’t include non-permitted information, you can request a review via Ads Manager under the campaigns table, or in Events Manager under the custom conversions page.
