Verifying Your Setup

This page details ways to verify that your setup is working correctly and is intended to help you to improve ad performance. The process of verifying your setup consists of:

Verifying that events are received correctly

Monitoring events received

After you send your events, confirm that we have received them in the Events Manager. You should be able to verify them within 20 minutes after they were sent.

To monitor events received in Events Manager, on the Data Sources page, click on the Pixel corresponding to the PIXEL_ID in your POST request. For more information, see Business Help Center: Navigate Events Manager.

Then, click Overview. Here, you will see the number of events we received before they are deduplicated, discarded due to consent controls and other policies, or processed. Under Connection Method, you see the channel in which that event was sent. You can click on each event type to get more specific information.

Monitoring event freshness

To help Facebook optimize your ads, we recommend that you minimize the time between when an event occurs (represented by the event_time parameter) and when it is shared with Facebook to be as close to real-time as possible.

You can use Events Manager to monitor event freshness. In the Overview page for a given Pixel, click on the Event Details button for an event to get more specific information. On this page, navigate to the Event Freshness tab. In this tab, you can see the average event delay time on a scale from Real Time to Weekly.

Verifying that events are deduplicated correctly

For optimal ad performance, we recommend that advertisers implement the Conversions API alongside their Meta Pixel. When advertisers do so, they must set up a deduplication method to help ensure that the ad delivery system is able to differentiate between distinct and overlapping events. Learn more about deduplication.

You can use Events Manager to monitor the percentage of events that were deduplicated. In the Overview page for a given Pixel, click on the Event Details button for an event type to get more specific information. On this page, navigate to the Event Deduplication tab.

This tab shows the following information:

  • Rate of Events Deduplicated: This is the percentage of events that have been deduplicated from each event source. Higher percentages are better, and a warning will appear when your deduplication rate is too low. You may be able to improve deduplication rates by adding more deduplication parameters to the event.
  • Rate of Deduplication Key Usage: This is the percentage of events from each source that contained each dedupe key. Overlap is the percentage of events with a given dedupe key received from both sources (as a percentage of the source with the fewest events received). Having low Overlap means that the implementation is either sending non-unique dedupe keys from one/either source or sending events with a dedupe key from only one source.

Verifying that events are matched to users with high accuracy

When your events are matched to people with a Facebook account, your events can be better utilized for ad attribution and optimization. In Events Manager, you can monitor Event Match Quality, a measure of how effective your server event’s customer information parameters may be at matching events to a Facebook account.

Event Match Quality is scored from 1 to 10. To monitor Event Match Quality, navigate to the Overview page for a given Pixel with the Conversions API.

Having a high Event Match Quality score can help decrease your cost per action. Where possible, we typically recommend that you aim for an Event Match Quality score of 6.0 or higher.
