CLIENT BACKGROUND

Who Was This Account?

This is an Amazon account we manage on an ongoing PPC optimization program. The brand is kept anonymous, but the account data is real. When we took over, spend was inconsistent and ads weren’t converting efficiently. Comparing the baseline period (25 May – 24 Jun 2025) with the optimized period (21 Jul – 20 Aug 2025), sales grew from £6,356 to £15,229 — a 140%+ increase — while ROAS improved and ACOS dropped.

PROBLEMS

What Problems Were We Solving?

The account needed to grow sales without letting advertising costs rise in step — the challenge was to scale revenue while actually improving efficiency.

01

Scaling Without Rising ACOS

In the baseline period the account did £6,356 in sales at a 27.49% ACOS. The goal was to push sales higher while bringing ACOS down — growing spend and efficiency at the same time, not one at the expense of the other.

02

Controlling Ad Spend

Sales needed to jump, but ad spend could not be allowed to jump with them. Every extra dollar of spend had to be justified by a stronger return — the aim was to grow sales far faster than spend.

03

Lifting Organic Alongside PPC

Growth couldn’t come from paid alone. We needed PPC to feed the flywheel — driving rank and visibility so that organic orders grew alongside paid orders and TACOS trended down.

OUR STRATEGY

How CaptenAMZ Drove the Growth

We applied our Beyond Average™ Framework — foundation first, then scale. Understand the market, tighten targeting, earn visibility, then push spend where it performs.

1

Market & Keyword Mapping First

Before adjusting bids we mapped the category — who ranks, what they charge, which search terms actually convert, and where the account could realistically win. That map guided every decision that followed.

✓ Full category & competitor mapping
✓ Search term & demand analysis
✓ Price positioning review
✓ Win-zone keyword shortlist

2

Continuous PPC Optimization

Campaigns were restructured for tighter control and cleaner tracking, then optimized week over week — bids tuned to performance, wasted spend pruned, and winning keywords scaled. The result: ACOS dropped from 27.49% to 22.52% while sales more than doubled.

✓ Campaigns restructured for control

✓ Wasted spend cut on low-converters

✓ Bids optimized to protect ACOS

✓ High-converting keywords scaled

3

Smarter Budget Allocation

Budget was reallocated toward the campaigns, keywords, and placements actually driving sales. Winning campaigns were scaled and underperformers paused, so spend grew from £1,748 to £3,430 while sales jumped from £6,356 to £15,229 — every pound worked far harder.

✓ Winners scaled, underperformers paused

✓ Budget follows performance

✓ Low-value spend cut

✓ Sales +140%+ on efficient spend

4

Doubled Down on Placements & Reach

We doubled down on the ad placements that were converting to widen reach and pull in more clicks, backed by hands-on daily management — monitoring performance, catching issues early, and making the small, consistent adjustments that compound over time.

✓ High-performing placements expanded

✓ Reach and clicks increased

✓ Daily performance monitoring

✓ Issues caught and fixed early
