Facebook added Performance Goals to ad set optimization.
Is this a big deal? Nope. It just rewords what was previously "Optimization for Ad Delivery."
The options are in plainer language so maybe it's clearer to the advertiser why they are selecting these options.
No new functionality. It's just a different way to show Facebook what it is you want to accomplish, what determines success or failure, and how your ads should be optimized.
That's it!
