Not only does Bïrch provide an extended list of TikTok metrics, but it also allows you to bring your own data into TikTok using custom metrics, which means you can:
use Google Sheets integration to source your rules with 3rd party data
create math operations with existing metrics
blend external data and TikTok data to create completely new metric
Let's delve into one example of creating math operations with existing metrics and use Cost per Engagement (CPE) metric. It's simple yet powerful - just divide your campaign's total cost by the number of engagements received.
This reveals the precise cost incurred for each like, comment, or share generated by your ad.
Now just go ahead and add this metric to the conditions of the rule by selecting it in Metrics -> Custom metrics:
For example, the rule below will notify me if the Cost per engagement of the active ad group for the last 7 days is equal to or greater than $5.
