Amazon Updates for Sellers – March and April 2025

Hello fellow Amazon sellers!

We wanted to share some exciting updates from Amazon that could make a big difference for your business this spring. 

Amazon has rolled out several impressive new features that we’ve been exploring, and we thought you might find them valuable too.

The platform has introduced new advertising solutions that work even as third-party cookies disappear, expanded display ad placements to Echo Show devices, and enhanced bidding options that offer more control while maintaining Amazon’s optimization benefits.

With Prime Day on the horizon (inventory deadline May 15th!), now’s the perfect time to understand these updates and position your business for success during Amazon’s biggest shopping event.

We’ve highlighted the key changes below so you can quickly see which ones might benefit your specific Amazon business strategy this quarter.

Let’s dive in and explore how these Amazon updates could help grow your sales!

Amazon DSP Integrates with Google Privacy Sandbox (March 20, 2025)

What’s New

You can now benefit from Amazon DSP’s integration with Google Privacy Sandbox, enhancing measurement capabilities despite third-party cookie changes. This integration supplements Amazon’s existing Ad Relevance solution powered by AWS AI.

Why It Matters

With third-party cookies becoming less reliable, this integration ensures you maintain comprehensive visibility into your campaigns. You’ll be able to attribute conversions from Chrome users regardless of their cookie settings, allowing you to continue measuring advertising effectiveness even as privacy standards evolve.

Takeaways

• This integration gives you a strategic advantage if you’re heavily invested in display advertising
• While competitors scramble for cookie alternatives, Amazon’s proactive approach ensures your performance tracking remains stable
• You have an opportunity to potentially outperform competitors who haven’t adapted their measurement strategies
• The combination of Ad Relevance and Privacy Sandbox integration lets you make more confident budget decisions based on accurate data
• If Chrome users represent a significant portion of your customer base, this update is particularly valuable for maintaining visibility into their behavior

Assets Based Creative on Alexa Home Screen (March 12, 2025)

What’s New

You can now run your standard Asset Based Creative (ABC) display ads on Alexa Home Screen (AHS) through Amazon DSP. This includes ads directed to any landing page, not just Amazon destinations.

Why It Matters

This update gives you access to Echo Show devices as an additional advertising channel using your existing creative assets. Alexa inventory is already enabled by default on Display Media Type Line items, making implementation seamless.

Takeaways

• Growing frontier for e-commerce sellers
• Extend existing display creatives to Echo Show devices without creating new campaigns
• Valuable for products needing visual demonstration or lifestyle context
• Test with visually appealing products or those solving problems in kitchen/living room areas
• Automatically enabled for Display Media Type Line items – extra impressions without extra work
• Reaches tech-forward demographics with higher disposable income and willingness to try new products

Amazon DSP Bid Adjustments (April 18, 2025)

What’s New

You can now leverage both simple and complex bidding algorithms through Amazon DSP’s new bid adjustment features. This includes single and multi-dimensional specifications within a single line item while still benefiting from automated optimization.

Why It Matters

This feature allows you to bring your proprietary data into Amazon DSP and create tailored, real-time bidding strategies aligned with your specific business goals. Bid adjustments reporting is available through the Reporting API, with console functionality to bulk apply adjustments to up to 10 line items simultaneously.

Takeaways

• Fundamentally transforms campaign optimization strategy on Amazon
• Replace multiple fragmented line items with fewer, more powerful ones while maintaining granular control
• Coty case study demonstrated 28% ROAS improvement and 36% new-to-brand ROAS lift
• Programmatically increase bids for high-value customer segments without sacrificing Amazon’s machine learning benefits
• Build segment-specific bid adjustments based on customer lifetime value, product margins, or inventory levels
• Bulk application for up to 10 line items enables rapid deployment of successful strategies across your portfolio

Sponsored Display Optimization Update (April 4, 2025)

What’s New

All your existing Sponsored Display Reach and Page Visit campaigns are being enhanced to optimize for conversion opportunities, aligning them with the optimization objective of Conversion campaigns.

Why It Matters

This machine learning algorithm update is designed to find improved conversion opportunities and drive incremental sales. You’re likely to see increases in performance metrics for your active Reach and Page Visit campaigns.

Takeaways

• Significant change in how Amazon values different types of ad impressions within campaigns
• System now prioritizes showing ads to users with higher purchase intent over maximum visibility
• Monitor campaigns closely for 4-6 weeks to observe performance shifts—potentially lower impression counts but improved conversion rates and ROAS
• Aligns with broader industry trends prioritizing performance over volume metrics
• For products with longer consideration cycles, helps connect upper-funnel awareness more directly to eventual conversions
• Consider reviewing campaign goals and metrics—previously reach-focused campaigns may now be better evaluated on conversion-focused KPIs

Amazon Accelerate Conference (September 16-18, 2025)

What’s New

The annual Amazon Accelerate selling partner conference returns to Seattle from September 16-18, 2025, offering opportunities to hear about new product announcements, participate in learning sessions, network, and receive personalized support.

Why It Matters

Whether you’re new to selling or an established brand, this sixth annual conference provides valuable insights and connections to help grow your business on Amazon.

Takeaways

• Amazon typically announces major platform changes and new seller tools at Accelerate, often with early access opportunities
• Q4 feature releases are usually previewed at this event, giving attendees 3-4 month competitive advantage in implementation
• One-on-one consultations with Amazon experts can resolve persistent account issues or uncover business-specific optimization opportunities
• Networking can lead to successful bundling partnerships, shared logistics arrangements, and valuable competitive intelligence exchange
• Consider sending different team members on different days to maximize coverage while minimizing travel expenses
• Early registration typically opens in June with discounted rates—set calendar reminder for late May or early June

Prime Day Inventory Deadline (May 15, 2025)

What’s New

To ensure your products are Prime-badge ready for Prime Day, you need to send your inventory to Amazon Warehousing and Distribution (AWD) by May 15.

Why It Matters

Having your inventory Prime-badge ready is crucial for maximizing sales during Amazon’s biggest shopping event. Amazon has expanded capacity in recently launched distribution centers across the US South Central, South East, and East Coast regions.

Takeaways

• May 15 deadline gives Amazon 4-5 weeks to process inventory before Prime Day (typically early-to-mid July)
• Sellers missing inventory deadlines see 40-60% lower Prime Day sales compared to those meeting deadlines
• Expanded AWD capacity in South Central, Southeast, and East Coast distribution centers improves delivery speeds to high-population regions
• Prioritize best-selling items and products with highest margins for Prime Day inventory shipment
• Use this deadline as leverage with suppliers who may expedite production when understanding the Prime Day opportunity
• AWD can serve as strategic overflow solution during high-volume period, reducing need for temporary storage
• Earlier shipments receive processing priority—aim to ship at least a week before the May 15 deadline
