AmpliSell’s B2B E-Commerce Blog for Amazon Sellers

When selling products on Amazon, one of the biggest decisions you'll face is choosing the right fulfillment method: Fulfillment by Amazon (FBA) or Fulfillment by Merchant (FBM). Both options have advantages, but when it comes to products that require customization, the decision becomes more complex.

Most sellers fixate on surface-level metrics, like sales velocity, restock alerts, and Buy Box wins. But after working with dozens of high-performing brands, we’ve learned that real profitability comes from the numbers most sellers overlook. What separates reactive sellers from top-tier operators is their attention to the metrics that drive margin, cash flow, and sustainable growth. Here are the three often-ignored metrics we monitor constantly for our clients—because we’ve seen firsthand the difference they make.

Many brands launch Amazon ad campaigns and then let them run untouched for months—or even years. But Amazon’s ad platform evolves fast. New formats, tools, and trends make yesterday’s winning strategy today’s wasted spend. If you haven’t updated your Amazon ads lately, this post is your wake-up call.

With Prime Day 2025 extending to four full days, it’s not just a longer sale—it’s a bigger operational challenge. For brands managing large catalogs, this added time means more chances to win the Buy Box, or burn through inventory budgets and storage space if you're not careful. Many sellers make the mistake of treating Prime Day like a liquidation event, dumping excess SKUs into FBA without a strategy. That can backfire, triggering long-term storage fees and poor sell-through rates.

In 2025, brands are investing heavily in social media platforms to build awareness. But a common question arises: "Can Amazon benefit from the traffic generated by these social media efforts?" The answer is a resounding yes. By strategically leveraging tools like Amazon Attribution and influencer partnerships, brands can convert social media engagement into tangible Amazon sales.

For brands considering Fulfillment by Amazon (FBA), the promise is clear: streamlined operations, Prime-eligible two-day shipping, and end-to-end logistics managed by one of the most sophisticated fulfillment networks in the world. FBA can help you scale faster, deliver exceptional customer experiences, and reduce the hands-on workload of managing orders and returns. But while FBA offers major advantages, it’s essential to understand the full scope of costs involved, which can impact your margins if you don’t plan for them upfront.

Minimum Advertised Price (MAP) policies set the lowest price at which a product can be advertised. These policies are designed to maintain brand value, support healthy profit margins for retailers, and ensure fair competition across sales channels. MAP violations typically occur when resellers promote products below the agreed-upon price set in the MAP policy, often driven by competitive pressures or attempts to win the Amazon Buy Box. When violations go unchecked, the consequences can ripple across your entire retail ecosystem.

In the fast-paced Amazon ecosystem, consistency isn’t just a luxury—it’s a necessity for driving strong ROI. Brands that work with stable account teams often see faster growth, fewer missteps, and higher returns on every dollar spent. In contrast, high agency turnover can set you back by weeks or even months, eroding ROI and disrupting your strategy. Let’s explore how long-term account management directly contributes to better ROI and how repeated onboarding due to high turnover drains your marketing performance.

If you’re spending your days fixing listing errors, chasing flat files, and managing support tickets—while your agency only runs PPC campaigns—it may be time to switch from an ad-focused provider to a full-service Amazon partner. One that goes beyond campaign optimization and actually lifts the operational burden off your shoulders. Here are three clear signs it’s time to make the move.

Repeat purchases are the lifeblood of sustainable growth. If your DTC store already offers subscriptions, it’s time to bring that strategy to Amazon—where Subscribe & Save (SnS) can help you turn one-time buyers into loyal, long-term customers.
