Example of what you could be seeing in your Facebook Ads Manager

Here’s another example:

This appears in the create/edit adsets view

Whats the source of this error?

Facebook has reacted to the iOS 14 data tracking changes by imposing a limit of eight events for optimization.

You will see the above error if:

  • You’re optimizing for an event that falls outside of your primary eight optimization events
  • You set up a conversions campaign and haven’t configured your eight events

What exactly is the 8-Event Limit?

Once Apple makes the new iOS tracking changes live, Facebook will enforce a 8-event limit on optimization events Be mindful that you can only optimize for one event out of the eight different events available per a domain.

Note: This limitation applier “per domain”.

How to configure these events?

Head over to Events Manager > Aggregated Event Measurement.

👆 Then click on the “Configure Web Events” button which will take you to the Web Event Configurations page.

☝️ On this screen, click on the domain you want to enable a particular event optimization method for.

Important: To be able to set these up, your domains need to be verified within the business manager. This can be done easily yourself, or you can ask a developer to do it for you.

Edit your events and set their priority levels

Let’s edit these events. Following is the order in which I optimized events for one of my domains. For you a different order of priority may make sense depending on the nature of your business.

I prioritized purchases because that’s what is important to me. For you it could be a registration or something else.

The order of these events matters. When Apple rolls out the iOS 14 tracking updates, Facebok will start ising “Aggregated Event Measurement”. Which means, Facebook will only receive a user’s highest ranked event from a user session.

These events may be ordered in any way you want depending on the use-case presented by your business. An example:

  1. Purchase
  2. Add Payment Info
  3. Initiate Checkout
  4. Add to Cart
  5. Lead
  6. Complete Registration
  7. Search
  8. View Content

If you want to use value optimization, please note that it will take up 4 our of the 8 events slots you’re allowed to configure.

You can also add custom conversions to the list of 8 conversions allowed.

Conclusion

For now, you can get away by not configuring these events. But once Apple rolls out the iOS 14 tracking changes, Facebook will enforce the 8-events limit.

If your adsets will be paused if they’re optimized for any events out of the 8-events that you must configure.

Although you can change the 8-events after Apple rolls out the iOS 14 tracking changes, it will cause your ads to stop and the changes might need upto a few hours (or days?) to propagate.

Hence, it’s important that you create a list of 8-events that are unlikely to change. Plan ahead, think carefully about what events you might or might not need in the future to avoid your ads being paused because you attempted to make changes to the 8-events or their order.

Happy advertising!
