"Prime Day didn't work for me."
We heard that a few times last year — and it's worth unpacking, because last year was also a record sales day for Amazon.
In the new episode of Human in the Loop, Teikametrics analyst William Fleisher makes the case that when Prime Day underdelivers, it's usually a strategy gap, not a demand gap. The biggest culprit? Treating Prime Day as a couple of event days instead of a window.
A few things that stuck with us:
→ The brands winning are doing the work early
— Sponsored Brands, Sponsored Display, and DSP in the lead-in build awareness so lower-funnel ads convert on the day.
→ DSP earns its keep in the lead-out too: retarget shoppers who viewed but didn't buy, at a cheaper cost than peak competition.
→ Success is measured across the full window and across retailers — not in a one-day silo.
Prime Day is next week. If you're still thinking about it as a date on the calendar, this one's worth 16 minutes.
