I’m puzzled by this: I thought it was well-understood, at least in the industry, that traffic numbers were at least mostly nonsense, and that ad click metrics especially were suuuper shady, typically more than half fraud; yet OP, in the business of “accurate ad spend analytics”, only just discovered this!? It just doesn’t ring true. That aspect of the story isn’t novel at all, and someone in that line of work should…
50k to 47 conversions seems like a noticeable increase in fakeness to me at least. that's going from more than half fraud to essentially only fraud with a rounding error amount of real users
For most consumers, it’s entertainment, but for industrial use it’s great for this kind of fraud. And very difficult to detect at scale, since the only cost effective tools for this kind of analysis are also ML/AI, and hence can be fooled more predictably/trained against.
