Prime Big Deal Days runs October 8 and 9. The sellers who come out ahead are the ones who set their account up before the event starts, not the ones adjusting bids while orders are coming in. Two days is a compressed window. If you are making structural changes during the event, you are already behind, and you are reacting to data that is too fresh to trust.
This is the setup checklist. Run through it before October 8. The goal is to enter the event with your budgets staged, your schedule dialed in, your placements documented, and a clean restore plan already on the calendar.
Set your event budgets with restore logic built in
Most sellers boost budgets manually before an event and forget to reset them after. The budget stays elevated for days or weeks after the event ends, and the performance data from a two-day high-volume window starts influencing decisions it was never meant to shape. Set your event budget boosts now, and set the restore at the same time.
Decide on a boost multiplier for your core campaigns. A reasonable starting point is 1.5x to 2x your current daily budget for your top-performing campaigns. The right number depends on your category, your margin, and how aggressively you want to compete for visibility during the event. Higher is not always better. A budget you cannot actually spend is just a number on a screen.
Once you have the multiplier, set the restore trigger before you close the tab. The rule should bring budgets back to baseline automatically once the event window closes. If your tool does not have restore logic built in, you need a calendar reminder and a manual reset plan. The alternative is what we covered in detail in the post on why Amazon budgets stay elevated after a sales event: spend that should have stopped in October compounds through November, and you enter your biggest sales season with inflated baseline costs.
Event budget rules operate differently from standing budget rules. If you are new to the distinction, the full framework for planning your ad scheduling across the year covers how to structure event windows as part of a broader calendar, including how to avoid having one event's settings bleed into the next.
Build your dayparting schedule around event buying patterns
Shopping behavior shifts during tentpole events. Buyers are more active earlier in the morning. Traffic spikes coincide with deal alert emails going out. The late-night hours are even more dead than usual because shoppers exhaust their buying intent by mid-evening, and they are not browsing casually the way they might on a regular Tuesday.
If you have not already set up a dayparting schedule, now is the time to read your hourly data first. Your Amazon dayparting heatmap shows exactly which hours convert and which hours burn budget. Build the event schedule from that data, not from a guess about what shoppers do during sales events in general.
For Prime Big Deal Days specifically: lean into the 7am to 2pm window for most product categories. Consider pausing the midnight-to-5am window if your historical data supports it. That window is typically low-converting even during regular periods, and during a two-day event you want every dollar going toward hours where intent is real. That said, do not change a schedule that is already working without data to back the change. If your current schedule is performing, the risk of restructuring it for a two-day window may not be worth it.
Check your placement multipliers
Top-of-search placement multipliers have outsized impact during events because shopper intent is high and competition for page-one placements is intense. Buyers during Prime Big Deal Days are actively looking. They are not scrolling past ads the way they might on a slow Tuesday. If you have not reviewed your placement settings recently, pull them now.
A 0% multiplier at top-of-search during a high-intent event window is leaving visibility on the table. A multiplier that made sense in September, when competition was lower and intent was more diffuse, may need to move up for October 8 and 9. Review your current placement performance data and decide whether an adjustment is warranted.
Document the current setting before you change it. Event traffic does not always perform the way you expect, and you want to be able to restore the pre-event setting cleanly when the event ends. A placement that looked like a strong performer over two days of elevated volume may look very different in the following week.
Stage your negative keyword list
Events bring new search traffic. Some of that traffic lands on terms you do not currently exclude. Run a search term report from the last 14 days and add any obvious irrelevant terms to your negative keyword list before the event opens. It takes 24 hours for Amazon to apply negative keyword changes, which means any additions you make on October 8 will not be active until October 9 at the earliest. Get this done before the weekend.
Do not add new keywords during the event. The data window is too short to evaluate performance during a compressed event period. A keyword that looks like it is converting on day one of a two-day event may have a very different story once you have attribution data from the full window. The right move is to run clean into the event and harvest search term data after it ends. Use that post-event data to build your next round of keyword additions and negative updates.
Set up the post-event cleanup before the event starts
This is the step most sellers skip. Before the event begins, document exactly what you changed: which budgets were boosted, by how much, and what the original settings were. If your tool does not log changes automatically, create a simple spreadsheet. The goal is to have a clear record you can act on when the event ends, without having to reconstruct what you changed from memory two days later.
Build a scheduled review for October 10, the day after the event ends. The check covers three things: are budgets back to baseline? Are any campaigns still showing event-level spend that suggests a rule did not fire? Is there unusual ACoS from the short event window that might be distorting performance rule decisions going into the following week?
The monitoring framework for this review is the same one you use for any post-event period. The Amazon ads monitoring checklist covers the specific signals to look for, including how to identify when a campaign's recent data is being skewed by event-period volume.
The quick-scan checklist (run through this before October 8)
- Event budget boosts set with restore logic confirmed. The boost amount is documented, and the restore rule is already scheduled to fire when the event window closes.
- Dayparting schedule reviewed against hourly data and updated if needed. If your schedule is already performing, leave it. If you have not set one up, do it now using pre-event heatmap data.
- Placement multipliers documented and adjusted. Pull your current top-of-search multiplier, note the baseline, and decide whether an event-period adjustment is warranted based on your performance data.
- Negative keyword list updated from the last 14-day search term report. Any additions need to be live before October 7 to be active for the full event window.
- Post-event cleanup date on the calendar (October 10). A review with no calendar block does not happen. Put it on the calendar now.
- Baseline settings documented somewhere you can find them. A spreadsheet, a note, a screenshot. The format does not matter. The point is that you have something to reference when you are restoring settings on October 10.
Frequently asked questions
How much should I increase my Amazon ad budget for Prime Big Deal Days?
There is no universal number. A reasonable starting range for high-performing campaigns is 1.5x to 2x your current daily budget. What matters more than the multiplier is having restore logic in place. A budget that stays elevated after the event costs you more than a conservative boost would have saved. Pick a number you are comfortable with, set the restore, and move on.
Should I change my keyword bids during Prime Big Deal Days?
Make bid changes before the event starts, not during it. Amazon's reporting data has a lag, which means changes you make during a two-day event are reacting to incomplete signals. You are not seeing what is actually happening. You are seeing a partial picture of what happened a few hours ago. Set your bids where you want them going in, and review after the event with a full data window.
Do Amazon dayparting rules need to change for Prime Big Deal Days?
Not necessarily. If your current schedule is based on reliable hourly data, it may already be close to optimal for an event window. The change worth considering is making sure your pause window is correct and that your peak hours are fully active. If you have not set up a schedule at all, use your pre-event heatmap data to build one rather than guessing at what shoppers do during an event.
