If your Prime Day felt more “meh” than “momentum,” you’re not alone.

Amazon stretched Prime Day into a 4-day marathon this year, and a lot of sellers burned out halfway through. The winners weren’t the loudest,  they were the most prepared.

Here’s what our ScaledOn team saw across accounts, and how you can turn that learning into your Black Friday comeback.

If your Prime Big Deal Days didn’t deliver the growth you hoped for, don’t worry - Black Friday and Cyber Monday are right around the corner. These events consistently drive some of the biggest sales surges of the year, and smart advertisers are already preparing to capture that wave.

At ScaledOn, we saw clients achieve up to 85% Year-over-Year growth during this Fall Prime Event.

Seller A

+85% YoY

Grew 85% YoY even with inventory challenges — they couldn’t send FBA stock for all SKUs. Imagine the growth potential with 100% FBA in-stock coverage.

Seller B

+56% YoY

Saw a 56% YoY increase, plus a 45% lift in daily sales versus their 30-day average.

⚡ Quick Insight

Prime Day is no longer a 48-hour sprint. It’s an endurance test.

The brands that paced budgets, prioritized FBA, and backed up ad setups crushed it (our top performer hit 80.7% YoY growth).

Those who went all-in on Day 1? Most ended up with tired budgets and flat ACOS by Day 3.

So if your Prime Day wasn’t the win you hoped for,  you’ve got one last window before 2025 ends to make it right.

As we helped clients navigate the Fall Prime Event, one message became clear - planning and patience are the real differentiators. The brands that prepared early, managed inventory smartly, and stayed consistent saw results like these:

The Takeaway?

Inventory planning and proactive advertising strategies are your biggest levers heading into the holiday rush. Don’t miss out on the momentum — plan your inbound shipments now and ensure your best ASINs are ready to capture demand.

🧠 Deep Dive:  Turning Prime Lessons into BFCM Wins

1️⃣Endurance Beats Aggression

In Amazon’s new 4-day format, Day 4 delivered +33% better performance for advertisers who held budget.

For BFCM, structure campaigns like a marathon, not a burst:

  • Split spend 40% early / 30% mid / 30% late (don’t empty the tank on Day 1) .

Plan for retargeting in the week after Cyber Monday. Post-event traffic converts surprisingly well.

And if you’re wondering what separated the top performers from the rest, Amazon Ads data backed it up - the biggest gains came from brands using a multi-format strategy across Sponsored Products, Brands, and Display. Here’s what the numbers showed:

If you were out of stock or missed inbound cutoffs for Prime Day, now’s the time to fix that.

🔑 Pro move: Get your top SKUs inbound by early November to guarantee holiday placement.

3️⃣ Multi-Format Ads = Maximum Uplift

Amazon’s data shows combining Sponsored Products + Brands + Display ads produced:

  • +64% uplift during Prime Big Deal Days

  • +62% uplift during BFCM

  • 4.05x average ROAS

That’s not theory, it’s math. Multi-format = multi-moment visibility.

4️⃣ Prep Like It’s Game Day

The smartest sellers did three simple things right before Prime Day:

  • Backed up ad configurations

  • Locked in bids and budgets ahead of event launch

  • Avoided “panic edits” mid-campaign that killed performance

Do the same for Black Friday,  or risk watching ACOS spike 300% overnight (we saw it happen).
