5 Last-minute Prime Day optimizations to boost 2025 sales

Based on insider insights from Amazon, Jungle Scout, and ChannelEngine shared during a recent Prime Day strategy webinar, here are five actionable, high-impact last-minute optimizations you can implement to make the most of this year’s Prime Day.

1. Double-check listing fundamentals

• You’re Prime-eligible (with the badge clearly shown)
• Hero images are mobile-first and clean
• Titles are clear, not crammed
• Product has 20+ reviews with 3.5 stars or more
• Bullet points are benefit-led, not keyword soup
  
  

“If you're missing one of these, the rest kind of fall apart… It just doesn’t feel right to the customer.”

Jason Rubenstein
Sr. Partnership Development Manager

2. Prepare for stockouts with hybrid fulfillment

• Use fulfillment overrides or Seller Fulfilled Prime as a fallback
• Sync FBA inventory with your ERP for accurate stock allocation
• Use buffers and soft reservations to avoid overselling
  
  

“It’s not just about the FBA warehouse. You need your own fulfillment connected as a safety net—especially on volatile days like Prime Day.”

Jordi Vermeer
VP of Revenue North America

3. Push pre-event visibility with strategic ads

• Allocate 40–50% of your ad budget to the lead-in phase
• Use DSP to retarget “add-to-cart” users and highlight review-rich products
• Test coupon ads and testimonials in creative formats
  
  

"We see a 6x spike in DSP spend during Prime Day… but some of the savviest sellers allocate their budgets pre, during, and post-Prime Day."

Jason Rubenstein
Sr. Partnership Development Manager

4. Bundle and discount with purpose

• Launch temporary bundles that maintain healthy contribution margins, and avoid margin-killing deep discounts.
• Use lightning deals to clear stale inventory
• Cap discounts at 15–30%, unless you’re launching or clearing out
  
  

“Brands like Sports Research that offered 30–40% discounts saw +93% search volume and +21% revenue, with effects that lasted beyond Prime Day.”

Tom Werle
Senior Vice President, Strategy & Operations

Prime Day isn’t just a sales event - it’s a brand moment. Use it to build awareness, drive top-of-funnel activity, and position your catalog to perform in the weeks and months that follow.

As Jungle Scout shared in the session, brands that entered with a clear understanding of their competitive standing in search, pricing, and assortment were the ones best positioned to win.

5. Automate to stay agile on the day

• Use repricing tools with minimum margin thresholds
• Automate campaign pacing so you don’t burn budget too early
• Sync inventory changes across all marketplaces in real time
  
  

“If your pricing isn't precisely benchmarked against the competition, you're flying blind. If you're off by even 10%, it could tank your ROI.”

Tom Werle
Senior Vice President, Strategy & Operations

TL;DR: Make the last days count

Focus on these five things:

• Polish your listings
• Avoid stockouts with hybrid fulfillment
• Launch pre-event DSP campaigns
• Bundle smart and discount strategically
• Let automation run the show
