Real-time attribution alerts during peak trading
Peak is when live alerting is most tempting and least trustworthy. What is genuinely watchable hour by hour, and what has to wait until the window closes.

Peak is when live alerting feels most necessary and is least trustworthy, because the same conditions that raise the stakes also distort every number you would alert on. Two things are genuinely watchable hour by hour. The rest waits.
Watchable and not
| Signal | Watch it live? | Why |
|---|---|---|
| Spend pacing against plan | Yes | It is a count, and overspend is unrecoverable |
| Site and checkout errors | Yes | It is a count, and it is fixable now |
| Orders against forecast | Yes, loosely | A count, though hour-level noise is high |
| Reported ROAS | No | Structurally inflated during peak |
| Causal estimate | No | Cannot resolve on a few days of unusual trading |
Why reported figures mislead most at peak
Three structural reasons, all working the same direction. Buying intent is elevated for everyone, so every touched conversion gets credited. Frequency rises, so more platforms claim the same orders. And discount-driven pull-forward is counted as new revenue rather than as the same revenue arriving earlier and thinner.
An alert on reported ROAS during peak will therefore fire positively and encourage more spend on exactly the channels most flattered by the conditions. The mechanism is in why the gap widens at peak.
What to do with the urge to act
Write it down instead. Keep a running note of what you would have changed and why, with timestamps. After the window, check the post-window read against those notes. That converts an unusable impulse into evidence for next year, at no cost.
The one alert that genuinely matters
Did the export or ingestion job complete. That is the failure you cannot repair afterwards, because the granular data behind the window can expire before you get to it, as covered in the two-month retention trap.
Everything else can be reconstructed later. That one cannot.
The read that is worth the wait
The post-window read, in the two weeks after the window closes, with definitions frozen before it opened. The calendar is in Black Friday measurement deadlines.
The honest version of the urgency
The deadline in peak measurement is not a countdown, it is that retention expires and definitions frozen mid-window cannot be un-frozen. Those are calendar facts. Live alerting on inferential numbers is not one of them.

What should I monitor live during Black Friday?
Spend pacing against plan, site and checkout errors, and orders against forecast loosely. All three are counts of things that happened. Reported ROAS and causal estimates are both unreliable in-window and should not drive live decisions.Why does reported ROAS mislead most during peak?
Elevated buying intent means every touched conversion gets credited, higher frequency means more platforms claim the same orders, and discount-driven pull-forward is counted as new revenue rather than as the same revenue arriving earlier.What should I do with the urge to change budget mid-window?
Write down what you would have changed and why, with timestamps, then check those notes against the post-window read.
