Every year, the advice is the same: start preparing for BFCM early. And every year, sellers start about three weeks later than they intended.
October 15 is a useful concrete deadline to work against. It is when holiday shopping traffic picks up meaningfully on Amazon for most categories, when CPCs begin to climb, and when competitors who prepared earlier start pulling ahead. It is also about six weeks before the main BFCM window, which gives you a realistic buffer to set up rules, test them, and catch issues before it matters.
This checklist covers everything that should be done by October 15. It is not a comprehensive account strategy review. It is the ad operations layer: the rules and automation that run your campaigns during the highest-traffic, highest-stakes period of the year.
Item 1: Update dayparting for Q4 traffic
Dayparting rules built on summer data are often wrong for Q4. Holiday shopping shifts the hours that convert. Evening windows tend to improve as buyers enter gift-shopping mode after work. Weekends carry more weight in November than they do in August. If your current schedule was built from Q2 or Q3 data, it may be suppressing windows that perform better in Q4.
What to do before October 15:
- Pull hourly performance data from your last Q4 (November and December) if you have it. Look at which hours drove the most conversions at acceptable ACoS.
- Update your dayparting rules to open evening windows you may have been suppressing. Specifically: 7 to 10 PM local in your primary market tends to shift upward in conversion rate during holiday season.
- If you have weekend suppression set, reconsider it. November weekends are high-intent shopping periods, not slow periods.
The goal is not to tear down your current schedule. It is to make sure the windows you are suppressing in Q4 are actually the low-performing ones, not windows that are low in the summer but strong in November.
Item 2: Set Q4 budget lifts
Your baseline campaign budgets should be set for normal operating conditions. Q4 is not normal operating conditions. CPCs are higher, competition is heavier, and more importantly, the upside is real: buyers in November have intent that they do not have in April.
A budget rule lets you raise spend levels on a schedule and restore them when the season ends. The restore step matters as much as the lift.
The pattern:
- Set a budget rule to activate October 15, raising budgets to your Q4 operating level (typically 20 to 50 percent above baseline, depending on your category and available inventory).
- Set the restore date for after BFCM ends. Early December is reasonable for most sellers. The rule restores to your original baseline automatically.
- Capture your pre-Q4 budgets as baseline snapshots before the lift takes effect. Off Hours handles this automatically when the rule first fires.
Sellers who skip the restore step carry inflated budgets into December and early January. This is the most common post-BFCM billing surprise, and it is entirely preventable.
Item 3: Build your Big Deal Days event rule
Amazon Big Deal Days typically falls in mid-October, which means it lands right at the October 15 threshold. Sellers who have not set up an event rule before then are scrambling to build one while the event is either imminent or already starting.
A Big Deal Days event rule should cover:
- Ramp: Start the day before the event to catch early-window traffic.
- Peak: The two-day event window at full boost (typically 50 to 100 percent above Q4 operating level).
- Restore: Immediate restore to your Q4 baseline after the event ends. Not to your pre-Q4 baseline, since your Q4 budget rule should still be active. Just back to the Q4 level.
If you have already set your Q4 budget rule (Item 2), the event rule boost is layered on top of it. Your restore after Big Deal Days brings you back to Q4 levels, not all the way to your normal baseline. Build the rules in this order to avoid confusion.
Event rules that restore correctly.
Off Hours event rules capture your baseline at first fire and restore automatically when the window ends. No manual cleanup after every event.

BFCM is different from Big Deal Days in one important way: the stakes are higher, and the window is messier. Black Friday is a single known date, but the effective BFCM window for Amazon sellers typically starts November 20 to 22 and runs through at least the following Monday (Cyber Monday). Some categories extend meaningfully into the following week.
Build your BFCM event rule with this structure:
- Ramp phase: Nov 20-26. Gradually lift budgets as early holiday shoppers begin searching. This captures early conversions without maxing out your budget before the peak.
- Peak phase: Nov 27-Dec 1. Full boost. This is the main BFCM window including Black Friday and Cyber Monday. This is where your highest daily spend belongs.
- Tail phase: Dec 2-7. Step down from peak but hold above your Q4 baseline. Conversion rates drop but intent is still elevated for several days after the main weekend.
- Restore: Dec 8. Return to Q4 operating budget. Your Q4 budget rule from Item 2 should still be active, so "restore" here means returning to Q4 levels, not to your pre-season baseline.
The most important part of this rule is the restore date. Set it explicitly. The number of sellers running BFCM-level budgets into mid-December because they forgot to restore is not small.
Item 5: Confirm spend alerts are on
Spend alerts are your early-warning system for the holiday period. They fire when daily spend spikes, drops, or drifts outside a baseline range. During Q4, these signals matter more than at any other time of year.
What alerts to have active by October 15:
- Spike alerts: If spend jumps significantly above your Q4 operating level outside an event window, that is something you want to know about immediately.
- Drop alerts: If campaigns that should be running go quiet, a drop alert catches it before you lose a full day of holiday traffic.
- Event restore confirmation: After Big Deal Days and after BFCM, confirm that budgets actually returned to the expected levels. A restore that failed silently is worse than no restore at all.
Spend alerts are included free on every Off Hours plan. They run under every rule type and fire to email when your spend goes outside expected range. For Q4 specifically, they are not optional.
The October 15 checklist at a glance
What happens if you wait until November
The risk is not that you cannot set up rules in November. You can. The risk is that you are configuring and testing automation during your highest-traffic period, which means any mistake is a live mistake. A dayparting error that costs you an hour of coverage in August costs you traffic you can recover. A dayparting error that pauses your campaigns on Black Friday is not recoverable.
Setting up rules in September and early October gives you time to find the things that need adjusting before the stakes are highest. It also gives you a realistic picture of what your Q4 spend structure looks like before you are in the middle of it.
The checklist above takes most sellers a few hours to complete. The return on that time, measured against what is at stake in November, is not subtle.
