use Conversion rate, bounce rate metrics in dashboard.
Please go through the below link on how conversion and bounce rate is caluclated.
You can use custom instrumentation to create a measure from the method that captures the revenue in a users PurePath. Or of course, another approach is to use capturing the meta tag value to capture price from UEM. Of course, you can then chart this in a dashboard after you have created a measure for it.
Depending on the applications that you are running, there might even be a FastPack that already has this instrumented for you. Link
Hope this helps,
