Prime Big Deal Days Hourly Playbook: When to Scale, When to Cap, When to Shift

Amazon’s big fall shopping event is a 48-hour event that can swing Q4. The window is short, the auction will be jumpy, and every sloppy decision in the first hours gets amplified by evening. The urgency is now: the prep you do this week determines whether Oct 7–8 runs smoothly or spirals.

One way to ensure that you’re considering everything to approach the event is to treat Prime Big Deal Days (Oct 7–8) as four 12-hour blocks, not “two days.” Build hard guardrails, hold back budget for the evening surges, and keep creative and targeting ready to swap on short notice. Prep your automation rules, pacing reserves, and retail-signal triggers now so you’re executing, not improvising, when the traffic hits.

Here’s why the four phases matter. Phase 1 (12:01 am–noon, Oct 7) is about a clean launch and tight search-term control so you don’t burn the morning. Phase 2 (noon–midnight, Oct 7) is fighting in the trenches. Pace for prime time, counter competitor pushes, and double down on what holds outcomes. Phase 3 (12:01 am–noon, Oct 8) is a softer, cheaper window where Day 1 learnings and inventory awareness pay off. Phase 4 (noon–midnight, Oct 8) is where you harvest recent intent, protect margin, and start the glide path without losing carryover demand.

What follows is the run-of-show that you can incorporate into your plan this week, along with links to the playbooks, infographics, and Celeste prompts on the Skai Holiday Hub, to help you execute this critical holiday season event successfully.

Phase 1: Early morning momentum (am–noon, Oct 7)

Teams are online early, triaging search terms, watching ROAS wobble, and fielding rapid stakeholder pings. Budgets are set; nerves aren’t.

Tip 1: Lock the launch — a clean handoff between automation and humans

In the first hours, prioritize stability over scale. Set CPC ceilings by keyword tier, avoid large bid jumps, and hold back a healthy slice of daily budget for the evening surge. Keep a small test cluster for manual tweaks to validate your pacing model, and document the changes made so the day team can replicate or roll back quickly. The goal from am to noon is clean data, steady reach, and clear guardrails, not maximum volume.

Skai client tip: Use Automated Actions with multi‑level conditions written as plain rules. Example: if a keyword’s CPC climbs above its ceiling while ROAS drops below your floor, reduce the bid by a set percentage and re‑evaluate in the next check window. When a key rival’s product goes out of stock, temporarily raise bids on your matching terms by about 20%, then return to baseline once they’re back. Pair this with Budget Pacing to reserve roughly 25–35% of spend for 6–10 pm. Label holiday activity so you can roll back smoothly after the event.

Tip 2: Stop the bleed fast — ruthless search‑term hygiene

Early discovery drives a significant number of broad, low-intent queries. Review search terms in short windows (every 2–4 hours), group weak queries by theme, and add negatives to protect the budget. Pin your highest‑intent exact matches so your hero items don’t get diluted by the morning’s exploratory traffic. Keep an eye on how these themes evolve across the morning as shoppers compare and bookmark.

Skai client tip: Pre-label must‑win terms so Share of Voice is tracked in Competitive Insights and set alerts for meaningful drops. For Celeste, keep prompts simple and task‑specific: From the Campaigns/Keywords grid, last 4 hours, list search terms with impressions at least 100 and conversion rate under 2 percent. Group by theme and propose negatives. Apply from Skai’s workflow and recheck in the next 2‑hour window.

Tip 3: Win the scroll — morning creative built for scanning

Morning audiences skim. Lead with value clarity like price off, bundles, and guarantees rather than end‑of‑day urgency. Track performance by hour block so you know when to shift tone, and keep a fresh variant ready in case CTR decays during the late morning. Treat this first part of the event as creative discovery‑friendly and informative, with a fast handoff to urgency later.

Skai client tip: Use Creative Center to schedule am variants and map results by time of day. Create an automation rule that swaps in a new creative set if CTR falls by a defined percentage or if conversion rate lags a rolling 3‑hour baseline. Stage an evening set that emphasizes urgency and limited‑time offers so you can switch quickly.

Tip 4: Stretch scarce stock — inventory‑smart bidding from hour one

If stock is tight, narrow to higher‑intent keywords and cap bids to stretch inventory into prime evening windows. Flag SKUs under a unit threshold for special handling, and avoid broad traffic that could drain remaining units without adding margin. Share a simple stock dashboard with the team so everyone sees the same risk picture.

Skai client tip: Connect retail signals and set Automated Actions in full sentences: when on‑hand units for a product drop below ten, lower bids by roughly 30–50 percent, and limit match types to exact or other high‑intent sets. When the item is replenished, restore the previous bids and match types. Use Portfolios to shift budget from constrained SKUs to similar in-stock items automatically.

Tip 5: Set the board — codify the Day 1 playbook by noon

From am to noon, capture what works and what wastes: keywords to protect, CPC guardrails that hold, creatives that move, and audiences that are starting to pop. This becomes the evening playbook, keeping the team aligned when pressure rises.

Skai client tip: Create a lightweight Phase 1 snapshot in Skai: pinned hero terms with target Share of Voice, CPC caps by tier, current ROAS floors, active automations, and creative status. Share it before lunch so the noon–midnight shift can scale with confidence.

Phase 2: Peak competition (noon–midnight, Oct 7)

Leadership wants scale by evening. Budgets risk over‑pacing by mid‑afternoon. Creative swaps and keyword moves are happening fast.

Tip 1: Save prime time — pace noon‑to‑midnight for the evening surge

Reserve roughly a third of the budget for 6–10 pm and check burn every 60–90 minutes. Keep ROAS floors or CPA caps in place to prevent growth from compromising margin. Use midday to verify which products and queries truly carry into the evening, then prioritize those paths.

Skai client tip: Use Budget Pacing with Portfolio reallocation so spend flows from under‑ROAS sets to winners in real time, while CPC caps keep inflation in check. Schedule simple pacing summaries so leaders see status without interrupting ops.

Tip 2: Outsmart, don’t outspend — reposition against competitor pushes

When rivals surge, don’t only match CPCs. Identify which of their products are driving the push and adjust your keyword coverage and copy to emphasize your advantages, such as price, bundle value, reviews, or delivery speed. Protect must‑win terms and avoid getting dragged into every fight.

Skai client tip: In Competitive Insights, trigger alerts when Share of Voice drops by twenty percent or more on priority terms. When a rival loses the Buy Box or goes out of stock, pair retail signals with Automated Actions to capture incremental demand, then automatically return to your normal settings when conditions stabilize.

Tip 3: Feed the winners — tune creatives and audiences for efficiency

Shift budget into creatives and audiences that deliver outcomes; pause assets that promise but underdeliver. Use clear thresholds so decisions are consistent across the team. Refresh ad copy or imagery if performance decays during the evening peak.

Skai client tip: Review Audience performance and Creative Center in tight loops. Reduce budgets on audiences with delivery issues and scale the ones hitting efficiency. Set automated alerts to catch swings quickly and keep a ready‑to‑launch evening creative set as backup.

Phase 3: Day two momentum (am–noon, Oct 8)

Some competitors sleep on Day 2 mornings. Your analysts are combing Day 1 learnings while sales asks, “What’s hot now?”

Tip 1: Own the quiet hours — promote risers, trim the rest

Day 2, early hours can be cheaper and less crowded. Upweight midnight to 6 am on hero terms, promote items with fresh momentum, and narrow broad matches if stock is thin. Recheck results by late morning to set up the evening push.

Skai client tip: Use Dayparting for Events to increase bids for off‑hours and scale back as competition returns. Ask Celeste: Compare Day 1 to Day 2 from 12:01 am to noon in the Products grid. List ASINs with conversion rate up at least 15 percent and recommend bid and budget shifts. Apply the changes and schedule a follow-up at noon.

Tip 2: Guard margin — throttle exposure as inventory tightens

As units drop, keep exposure focused on higher‑intent terms and ensure bids reflect the remaining margin. Avoid pushing items that can’t sustain demand through the evening.

Skai client tip: Set straightforward Automated Actions: when on‑hand falls below ten units, cut bids by about a third to a half, and limit match types to high‑intent. When stock returns, restore the prior bids and coverage. Mirror these controls at the Portfolio level so budget gravitates to in‑stock winners.

Tip 3: Load the night shift — capture AM learnings for the final push

Log which terms and creatives rebounded on Day 2 morning, and note CPC ceilings that held under renewed pressure. Use these notes to plan your final surge.

Skai client tip: Save a Phase 3 snapshot in Skai priority terms, including SOV, CPC caps, and creative performance, and prepare an evening pacing plan. Schedule an Instant Presentation for end-of-day stakeholders so they can see the plan and the proof.

Phase 4: Final optimization window (noon–midnight, Oct 8)

Fatigue sets in. Finance is watching margins; media is pushing for a last lift. Stakeholders want a readout before midnight.

Tip 1: Harvest intent — remarket recent engagers, not cold traffic

Late buyers convert best when they’ve already shown intent. Shift from prospecting to remarketing: product viewers, category browsers, and cart adders from the past 48 hours. Keep frequency sensible to avoid burnout and watch for rising CPCs that don’t translate to sales.

Skai client tip: Build recency cohorts in Audience Manager/AMC and activate Sponsored Display against product or category viewers. Keep CPC and frequency caps tight, and monitor Share of Voice only on your must‑win terms so remarketing gets priority.

Tip 2: Land the plane — glide bids down, keep momentum

Plan a post‑event glide path. Reduce bids about ten percent per day over five to seven days while you capture list‑savers and late buyers. Avoid the temptation to cut everything at once—momentum lingers longer than the banner.

Skai client tip: Use pacing monitors and Automated Actions to taper bids and budgets gradually. Send a brief daily summary to stakeholders so the slowdown is visible and intentional. When ready, revert to pre‑event settings with bulksheets.

Tip 3: Bottle the playbook — package insights for the rest of Q4

Build a short readout by time window, including ROAS, CVR, CPC changes, consistent performers, and event-only terms. Turn these into reusable guardrails for Black Friday and Cyber Monday.

Skai client tip: Ask Celeste for a post-event brief. Create an executive summary of the four 12-hour windows, including ROAS, CPC, CVR, top terms, and three to five next steps. Export an Instant Presentation and schedule delivery so leadership gets the recap without another meeting.
