we need to stop obsessing over last-click attribution because it is fundamentally broken in a privacy-first world. the real metric that matters is incremental lift, not some imaginary path to conversion

the problem is that most people treat incrementality like a magic wand when it's actually just an expensive way to validate what we already know. if you don't have the budget for massive-scale geo-testing, you're stuck in this limbo of trying to use probabilistic modeling to fill the gaps left by signal loss. i've been running causalimpact in python to try and bridge that gap on smaller datasets where traditional lift studies fail. it's not a silver bullet for every campaign, but it beats relying on a single cookie-based touchpoint.

this is the right direction, but we also need to talk about how much measurement overhead this adds to small teams. how are you handling the lack of granular signal when setting up your control groups?
