Inventory, Listings, Ads: The Ultimate Prime Day 2025 Prep Checklist for Amazon Sellers

Amazon has just raised the stakes. Prime Day 2025 will now span four full days—the longest Prime Day in U.S. history. Last year, Amazon reported over 375 million items sold during Prime Day. With four days now on the clock, that number could skyrocket. For brands, this means more time to drive conversions, more visibility opportunities, and yes, more pressure to get everything right. If you’re selling on Amazon, this extended shopping event is not just an opportunity—it’s a strategic moment that demands sharp planning across inventory, listings, and advertising.

As a service provider specializing in account management, Amazon listing optimization services, PPC, A+ Content, and consulting, we have developed this comprehensive checklist to help you and your brand succeed during Prime Day 2025.

Let’s break down what’s new, what it means for you, and the key actions to take now.

What’s New for Prime Day 2025

Prime Day 2025 isn’t just longer—it’s designed for greater deal visibility and seller participation. Here’s what’s changing:

• 4-Day Sale Window: Expanded from two days, giving you twice the chance to attract and convert shoppers.
• More Deal Placements: Amazon is prioritizing high-performing deals with 40%+ discounts for top visibility.
• Flexible FBA Shipping Deadlines: Two shipping windows let you choose between “minimal shipment splits” or “Amazon-optimized shipment splits.”
• Updated Deal Submission Deadlines:
  • May 5: Final day to submit Prime Exclusive Discounts.
  • May 23: Last day to submit Lightning Deals and Best Deals.
  • June 9: Deadline for FBA shipments with minimal splits.
  • June 18: Deadline for FBA shipments with Amazon-optimized splits.

How to Prepare for Amazon Prime Day

1. Inventory Planning: Stock Smart, Stay Competitive

• Forecast with Data: Analyze your Prime Day and holiday season sales data to forecast demand accurately. Use Amazon Competitive Intelligence tools to evaluate market trends and competitor behavior.
• Tactical Stocking: Based on your forecast, prepare enough inventory to meet four days of potentially accelerated demand, and plan for post-event demand spikes.
• Leverage FBA: Fulfillment by Amazon offers quicker delivery, Prime eligibility, and stress-free logistics. Use it wherever possible to boost visibility and conversion.
• Vendor Central Users: Ensure your purchase orders are processed and confirmed early. Confirm lead times and logistics alignment with your vendor manager.

2. Optimize Listings to Convert Shoppers

Your product listings are your digital storefront. Optimize Amazon listings for Prime Day and make every detail count.

• Keyword-Rich Titles: Use high-performing, relevant keywords to ensure discoverability. Your product title should be clear, concise, and benefit-driven.
• Detailed Descriptions: Address common questions and highlight key use cases. Focus on the problem your product solves.
• Bullet Points with Benefits: Go beyond features—sell the benefits. Use bullet points to break down what matters most to your target audience.
• High-Quality Images: Invest in professional, high-resolution product editing services. Include lifestyle images, infographics, and Amazon 3D rendering to showcase features in action.
• Encourage Reviews: Customer reviews are social proof. Use automated email follow-ups and post-purchase strategies to encourage satisfied buyers to leave positive feedback.

If you need help, consider Amazon listing optimization and product description writing services to refine your content for higher conversions.

3. Build Attractive Deals and Promotions

Success during Prime Day hinges on the quality and visibility of your deals. One of the Amazon Prime Day strategies includes building attractive deals and promotions:

• Prime Exclusive Discounts: These are promoted directly to Prime members. Ensure your top products have competitive discounts and focus on the Amazon Prime Day marketing strategy.
• Lightning Deals: Time-limited and quantity-bound, Lightning Deals create urgency. These are more effective when inventory is sufficient and the discount is deep.
• Best Deals: These run longer than Lightning Deals and can offer excellent exposure, especially if the discount is 40% or more.
• Coupons & Bundles: Offer bundles of complementary products to increase average order value, and use dollar- or percent-off coupons for added incentive.
• Know Your Margins: Don’t offer discounts blindly. Analyze your profit margins and select products where aggressive pricing still brings returns.

4. Supercharge Your Advertising Strategy

Ads are your power tool to win traffic during Prime Day. Increase Amazon Prime Day sales by following these quick tips.

• Sponsored Ads (PPC): Ramp up bids on Sponsored Products, Sponsored Brands, and Sponsored Display campaigns. Target Prime Day keywords and branded terms. We at Data4Amazon can help you with reliable Amazon PPC Management.
• Budget Smartly: Increase your ad spend during Prime Day. Don’t let your campaigns run out of budget at peak hours.
• Target the Right Keywords: Use tools to find high-volume, high-intent search terms. Consider long-tail Prime Day-specific keywords.
• Negative Keywords: Prevent wasted ad spend by excluding irrelevant keywords.
• Landing Pages: For Sponsored Brands, create custom Amazon storefronts or deal-specific landing pages to drive focused conversions.

5. Showcase Your Brand with A+ Content

• Amazon Storefront: Build a branded shopping experience where customers can explore your full product range and Prime Day deals. This increases cross-selling and customer engagement.
• A+ and Premium A+ Content: Use visuals, charts, and enhanced formatting to tell your brand story and answer objections. A+ content can significantly improve conversion rates. Professional A+/Premium A+ Content development ensures your pages stand out from the crowd.

6. Tighten Fulfillment and Customer Service

• Fulfillment Strategy: Whether you’re using FBA (Fulfillment by Amazon) or FBM (Fulfillment by Merchant), ensure smooth inventory management and prompt shipping. For FBA, monitor stock levels and optimize listings; for FBM, handle fulfillment and customer service directly to maintain high satisfaction.
• Track Inventory Closely: Stay in sync with stock levels throughout the event to avoid missed sales due to stockouts.
• Customer Support: Prime Day is high-volume, so expect more inquiries. Set up fast-response systems, FAQs, and support channels to manage expectations and reduce order issues.
• Account Health Monitoring: Keep an eye on late shipments, return rates, and customer satisfaction to ensure your metrics stay within safe limits.

7. Monitor Performance and Stay Agile in Real-Time

• Live Monitoring: Watch ad spend, conversion rates, sales velocity, and Buy Box win rate.
• Adjust As Needed: Be prepared to shift budget, update keywords, or boost bids based on real-time data. Use insights from Sponsored Ads to quickly optimize.
• Buy Box Tracking: Keep an eye on your Buy Box ownership, especially for competitive listings.

This is where having Amazon Seller Central Management or Vendor Central Management support is invaluable—real-time adjustments can make or break your campaign performance.

8. Post-Prime Day Analysis and Engagement

Once the dust settles, the work isn’t over.

• Data Review: Analyze what worked and what didn’t—inventory management, ad performance, sales patterns, and customer feedback.
• Customer Follow-Up: Send post-sale emails asking for reviews. Offer loyalty discounts or sneak peeks for future deals.
• Performance Benchmarking: Compare metrics with previous Prime Days and major sale events. Use this data to plan future campaigns.
