Prime Day

Prime Day is Amazon's headline annual event for Prime members, traditionally a 48-hour window in mid-July, with a second Prime-exclusive event ("Prime Big Deal Days") held in October. For accounts that participate seriously, the two events combined typically deliver 8–15% of full-year revenue across roughly 4 days of trading.

What "participating" means

Eligibility for a Prime Day deal badge requires (varies by year, check the current cycle):

• A qualifying Prime Exclusive Discount, Lightning Deal, or Best Deal active during the event window.
• Minimum discount threshold (Amazon publishes per-marketplace).
• Inventory cover (Amazon's projected sell-through forecast must be matched by inbound inventory at the FC weeks in advance).
• Star rating threshold (typically 3.5+).
• No active policy violations.

Preparation timeline

A defensible 8-week countdown:

T−8 weeks  Deal submissions close (Amazon's deadline)
T−6 weeks  Inbound inventory must be in transit
T−4 weeks  Inventory received at FC; coupon/PED scheduling locked
T−3 weeks  Branded campaigns ramp; review velocity push
T−2 weeks  Sponsored Brands creative finalised
T−1 week   Budget caps lifted on key campaigns; dayparting rules disabled
T−0        Live; hourly Marketing Stream monitoring
T+1 week   Post-event teardown, harvest, negation

PPC strategy during Prime Day

Three patterns that matter:

1. Don't get caught budget-capped. A campaign that runs out of budget at 11am on Prime Day forfeits 13 hours of the most expensive traffic Amazon will sell all year. Either remove daily caps or raise them 5–10× the steady-state level.
2. Bids up across the board. CPCs typically inflate 40–80% versus baseline. Holding bids at baseline means losing impression share to competitors who raised theirs.
3. Hourly monitoring via Marketing Stream. Standard 14-day reporting cycle is useless across a 48-hour event. AMS hourly data lets you cut a losing bid in hours rather than days.

What to defend, what to push

• Defend branded keywords aggressively — competitors run their loudest conquest campaigns during Prime Day.
• Push new-to-brand traffic on competitor keywords — high-intent shoppers are willing to try new brands during deal events.
• Pull back on low-CVR discovery campaigns where the deal-day CPC inflation isn't justified by the conversion lift.

Common mistakes

• No deal scheduled. Participating in the workload (inventory, ads) without participating in the event (deal badge).
• Inventory stockout mid-event. All marketing spend post-stockout is wasted; the listing falls out of ranking.
• Forgetting the post-event ranking afterglow. The 7–14 days after Prime Day usually see elevated organic ranking; budget for it.
• Running standard dayparting rules. Most dayparting models trained on normal demand are wrong by 5× across Prime Day.
