Notes

This warning happens when two objects have the same tracking ID seen in the URL, and so the system does not know which object to edit/assign data. If the duplicate tracking is associated with 1 object that is active/paused and 1 object that is also active/paused, conversions will not attribute at all in the account. Revenue will fail to attribute since the system does not know which active/paused object to assign the conversion to.

If the duplicate tracking is associated with 1 object that is deleted and 1 object that is active/paused, conversions will know to attribute to the active/paused object. The deleted object will not get assigned any conversions since the system will give precedence to the active/paused object. Even though revenue may still attribute, you will continue to get a warning that there is a “duplicate tracking value” when attempting to edit the duplicated object. This can be a problem if this prevents the edits from being posted to the publisher. It is therefore best practice to not have any duplicate tracking IDs in the account, and to remove them once these errors appear.

Autocorrect is turned on    

• With existing objects, perform a manual sync either through the Linking Wizard (to sync the entire publisher account) or on the Groups tab (to just sync specific groups). Please see this article for steps on how to perform a  manual sync. After synchronization is complete, you will see an item in Activity Log with “URL AutoCorrect: X Google Keywords.” No other action required.
• With new creations, Auto Correct will be automatically fix duplicate tracking ID's when creating new objects and this warning can be ignored.
• For Google keywords with duplicate tracking IDs, export the appropriate keywords to Excel by creating a report with the Account, Campaign, Group, Keyword, Match Type, and Custom Parameters columns. Once your report has been imported into Excel, delete the contents of the Custom Parameters column while keeping the column header.  You can then bulk upload the file back into Marin. 
• If the duplicate tracking IDs are shared between Google and Microsoft keywords, export the appropriate keywords to Excel by creating a report with the Account, Campaign, Group, Keyword, Match Type, and Custom Parameters columns. Once your report has been imported into Excel, delete the contents of the Custom Parameters column and update them to contain mkwid=[uniq_id]. You can then bulk upload the file back into Marin. 
• (Note: The following only applies if you have not migrated to Microsoft's Upgraded URLs. If you've already migrated, you can use the same columns as Google above). For Microsoft keywords with duplicate tracking IDs, export the appropriate keywords to Excel by creating a report with the Account, Campaign, Group, Match Type, and Destination URL columns (or Click Through URL if using redirects). You can then bulk upload the file back into Marin.

Autocorrect is set to "Warn Only"    

• With existing objects, perform a manual sync from the publisher account settings page. After synchronization is complete, you will see an item in Activity Log with “URL Issues (x of x Keywords, x URL Corrections) - File (with URL Corrections).” This file will contain a modified tracking ID. Open this file, remove the Uploaded Destination URL and Results columns and re-upload.
• With new creations, Auto Correct will automatically create a similar file in the Activity Log as above. Open this file, remove the Uploaded Destination URL and Results columns and re-upload.

Autocorrect is set to "Off" 

• Autocorrect will not work and duplicate tracking ID's will need to be manually changed. To do so, please follow the steps outlined below:

1. Download a report containing the affected URLs.
2. Look through the URLs and replace the duplicated alphanumeric value with the string [uniq_id].
3. Re-upload the URLs to the Platform. This will force the Platform to generate a new numeric ID, provided the Unique ID column is blank in the interface.

Regarding creatives      

• If all keywords in a group HAVE Destination URL’s, then Autocorrect will ignore creative duplicate tracking ID’s since editing creatives affects quality score and revenue will still attribute at the keyword level. However, if all keywords in a group DO NOT have URL’s, then duplicate creative tracking ID’s will either warn or fix automatically depending on your setting.
• Autocorrect will need to be turned ON for creatives in order to fix duplicates. This can be found in the URL Builder page under the Advanced Options drop-down.

For Facebook creatives    

To prevent that tracking in Facebook fails because of duplicate tracking ID in the account (creative level), please try these:
 

1. Keep watching the new uploads. In the Creatives tab, filter for creative in Editing or Sync Error status, select the failed rows and click the Resume button ('play' icon) to repost them.
2. Try your best not to adjust any creative directly in Facebook once you create them (for example Page Post link Ads). Do a manual sync as soon as you finish editing, so the Platform catches up the change in time.
3. Perform a manual sync regularly (for example per week) across all campaigns. If the URL Auto-Correct is on, you get a warning when there is duplicate tracking ID in the account.
    

If needed, a member from our Support Services team may create a report containing all duplicate keyword and creative tracking ID’s in the account. Please file a ticket if you would like this report send to you.
