Home Decor on Amazon: ads-only scope, and a rising ACOS we are working on.

A larger portfolio brand where Stegos's mandate is ads efficiency only, not overall business growth. Rising ACOS here is informing the current optimisation plan.

The starting point

The situation

This is a larger portfolio brand where Stegos's mandate covers ads efficiency only, not overall business growth. The reporting window runs from December to February.

We include it because it is not a clean win, and because the scope matters when reading the numbers.

The work

What we did

  1. Ads-efficiency work only: structure, search-term control and budget allocation within the existing campaigns.
  2. Monitoring ACOS by campaign to see where the increase was coming from.
  3. Using the rising ACOS as the starting point for the current optimisation plan, not as something to explain away.
The numbers

Reading the results

Ad spend +15%

Ad spend rose 15% across the window, a modest increase.

ACOS 22.8% (Feb)

In February the account's ACOS was 22.8%, equivalent to roughly 4.4x ROAS. That is not high in isolation, but the direction of travel is up.

Scope: Ads-only

Stegos does not control pricing, inventory, listings or the wider business here, which limits what ads work alone can fix.

What happened

The outcome

ACOS has been rising. That is informing the current optimisation plan, which looks at where efficiency is leaking inside the campaigns we control.

It is a good example of why scope matters: some causes of a rising ACOS, such as price or catalogue issues, sit outside an ads-only mandate and need to be raised with the brand rather than solved in the account.

Takeaways

What we took from it

  • Rising ACOS is a prompt to investigate, not to explain. The first question is always where the increase is concentrated.
  • When scope is limited, say so, and say which levers are out of reach.
  • Show the awkward accounts alongside the good ones. It is the only honest way to present results.

What happens next. The next review focuses on the campaigns driving the increase and on whether any of the causes should be raised with the brand outside the ads scope.

Spend scaled 5.7x in three months to capture more inventory. Efficiency softened as expected with that scale, but total sales still grew well ahead of it.
