The Criteo OneTag is placed on each page on your website in order to pass data to Criteo. The setup of your events directly impacts the performance of your campaigns.
To check that your OneTag is working properly, open Assets > Events tracking. Here, you'll have an overview of the current status of the Criteo OneTag on each page of your website. If your events are not working properly, you can use the graphs on the Events timeline by type section to see when the issue occurred and for how long.
There are three possible statuses for each section’s event: Working, Optimizations, or Issues.
If the status indicates an issue, there are errors you need to solve. The Optimizations status indicates that there are no critical errors, but there may be certain optional parameters that are not being passed.
To download the full report for any event with warnings or errors, click the download icon under Actions column.
In the downloaded .csv file, check columns H and I for more details about the error.
Request support from Criteo if you need help to solve the warnings.
The Criteo OneTag test report provides information on whether or not the events on each page type are functioning correctly. The file contains information about:
Last events listing: available for every page type
Top non-displayable Product IDs: available for Search Listing, Product Listing, Basket, and Sales Confirmation pages
Duplicated Transactions IDs: available for the Sales Confirmation page only
Last events received
In this report we log the details of a sample of events recorded during the last 48 hours.
Top non-displayable Product IDs
This report calculates your Feed and Tag quality. The quality represents Criteo's ability to correlate the product information passed through the events with the information provided in your product catalog.
Tip: Try to keep this number above 80% at all times. If the quality falls below 60%, it will impact the performance of your campaign.
Duplicated Transaction IDs
This report logs the details of the transactions with the same ID.
