The question we hear most often from Amazon brands is some version of: "We're already running ads: how much better can it really get?" The honest answer is that it depends on how your campaigns are being managed right now. The less honest answer would be to not show you the numbers. So here are the numbers.
We pulled performance data for three brands across different categories, comparing the same number of days before and after CentralDesk was introduced to their accounts. Same length windows, matched to the day the first change was made. Here's what happened.
A CPG Brand: Spending Less, Selling More
Over a matched 13-day window, this brand's ad spend dropped 23% while sales increased 14.8% and orders grew 15.4%. ROAS improved 49.1% and CVR climbed 35.5%.
The spend reduction wasn't the goal in itself. It was the byproduct of cutting waste: pausing underperforming placements, tightening bids on low-converting keywords, and letting the budget work harder on what was actually converting. Fewer impressions, fewer clicks, more sales. That's the direction you want those numbers moving.
A Health and Beauty Brand: The Biggest Improvement in the Set
Over a matched 10-day window, this brand's ROAS improved 93.3%. Sales increased 103.6% on a spend increase of just 5.3%. Orders doubled and CVR improved 94.6%.
The gains here came from identifying where the budget was concentrated on low-converting placements and redirecting it. CentralDesk's reporting makes that visible quickly, and the automation acts on it. The same budget, pointed at what converts, produces a very different result.
An Apparel Brand: Efficiency Gains on an Already-Tight Account
This brand came in with solid fundamentals and a well-managed account. The harder question is how much headroom is left when things are already performing well. Over a matched 2-day window, ROAS improved 14.8% and CVR jumped 21.1%. Spend was down 2.2% while sales grew 12.4% and orders increased 13.6%.
The window is short, and two days isn't the same as two months. But the direction is consistent with what we see across accounts at this performance tier: there's almost always incremental efficiency available, and it usually comes from better placement-level data than most brands have access to through standard Seller Central reporting.
What the Averages Look Like
Across all three brands, the simple average improvements are: ROAS +52.4%, CVR +50.4%, Sales +43.6%, Orders +43.0%, and ad spend -6.6%. CTR improved 15.2% on average, which means the traffic that did come through was better qualified than before.
These aren't outliers selected to make a point. They're the accounts we had data for with clean before/after windows at the time of writing. The patterns hold because the underlying mechanics are consistent: better reporting reveals where spend is wasted, automation acts on it faster than manual management can, and the account improves.
What CentralDesk Is Actually Doing
The results above come from two things working together. First, CentralDesk's reporting gives you a clearer view of campaign performance than Seller Central's native tools do: placement-level data, buy box awareness, and account health signals all in one place. Second, the automation layer acts on that data: pausing ads when you're not in the buy box, adjusting bids based on actual conversion patterns, managing budgets automatically so spend follows performance rather than the calendar, and flagging issues before they become expensive.
The combination means you're not just seeing the problem faster. You're fixing it faster. For agencies managing multiple brands, that's the difference between staying on top of every account and hoping nothing breaks over the weekend.
CentralDesk offers a 7-day free trial with no credit card required. If you want to see how your account compares before and after, that's the place to start. If you'd rather talk through your specific situation first, schedule a call and we can walk through your numbers together.
