There’s a universal data model that can answer any business question. It’s called language. @ae4ai gets data to tell stories in language everyone can follow. @econ4business mises.org/library/ahmed-elsa…

Query optimization is no longer just about speed. These days it’s increasingly about cost. Cloud warehouses will gladly run your inefficient queries and charge you for it. A slower query that spends $0.01x is often better than a really fast query that spends $1x

It’s quite weird that we let Facebook and other ad platforms calculate their own ad ROI. It’s like asking a student to grade their own tests; the difference between their “honest evaluation” and reality can be quite vast -- (1/2)

I’ve seen 4x ROI in ad manager and .9 when computed internally. Is that normal, or an outlier? What has your experience been comparing internally computed ad ROI to what Facebook claims? (2/2)
