What are Facebook Custom Metrics?

Facebook Custom Metrics is a Facebook Ads feature that lets you create your own metrics in the Facebook Ads reporting area from other predefined Facebook ads metrics.

Facebook Custom Metrics can be useful for two main reasons:

  • you can create ad metrics that are important for your specific business and industry
  • you can analyze the results of your FB ad campaigns with more insightful metrics without exporting the Facebook ads data to a spreadsheet or a 3rd party tool (e.g. Google Data Studio).

The Custom Metrics you create can be shared with anyone who has access to the Facebook Business Manager, or you can also choose to be only be seen by you.

Outbound click vs Landing Page View ratio – Custom Metric

A typical phenomenon with Facebook traffic campaigns is that Facebook sends junk traffic to your website and the users leave your landing page immediately before the page would load in. In this case, your Facebook Ads reporting would record an outbound click but not a landing page view. This metric will show if this issue is present with a specific FB ad campaign.

If this ratio is less than 80% and you are not running a traffic campaign, it is also worth checking with Pixel helper if your Pixel Events are configured the right way. Maybe a bad Pixel set up is causing the issue.

To get this Facebook Custom Metric you need to divide the number of Outbound Click by the number of landing page views.

Outbound Click to AddtoCart Ratio

To be able to use this metric, just simply divide the number of Add to carts by the number of purchases.

This metric can be very useful to check. If there is huge churn from people who added to carts to purchase, maybe your shipping fee is too high, or you are not shipping to important countries, or there is an issue with your checkout software, etc.
