FB has also lied consistently about the performance of their ad products, so who knows if you are really getting that ROI.

i know... and so do probably most major and direct response marketers.

there are a lot of ways to measure outside of FBs analytics tools.

including the very simple simply using a refcode or even a specific product/url. How many purchases did you get / how much did you spend?

this is what i'm referencing. like that's so incredibly basic and it bugs me HN just either doesn't understand or lets their opinion on it go first

In my experience FBs inaccurate reporting is just a tiny amount of impressions delivered and they refund the $1 or whatever it is a couple times a year. Have they ever had a reporting anomaly on their analytics tools for tracking off FB conversions? they very well could have but I haven't heard of one.

There is no way to validate their impression/click data that all the downstream metrics are reliant on. If you have a way, I'd love to know about it. The claim isn't that they make up conversions, the claim is that they overstate the ROI and cv% based on the denominator.
