Advent calendars going up in Q4 is expected. That’s not an insight.
The real edge is spotting which specific variant is winning before the rush.
Example: “wooden advent calendar” has been climbing steadily since early August (chart). That’s the kind of signal that helps you:
pick the right product style (not just the category)
shift PPC into rising terms earlier (cheaper than late Nov/Dec)
plan inventory around the winning variant, not generic seasonality
Curious: what other specific products are you seeing move this year ?
