01The challenge
A beauty and personal care brand was putting 21.95% of its sales into advertising. Between Sept 22 and Sept 30 the account did $85.7K in sales on $18.8K of ad cost.
That is a lot of ad dollars chasing traffic that was not all earning its keep: irrelevant search terms, bids that kept CPC higher than it needed to be, and budget parked on campaigns running high ACOS.
02The approach: The Waste-Out Reallocation
The Waste-Out Reallocation is a cleanup-first sequence. Take the waste out, then move the freed budget to what converts.
Take the waste out
Added negative keywords to cut irrelevant traffic, and paused the campaigns running high ACOS so they stopped drawing budget.
Lower the cost of every click
Optimized bids to bring CPC down and restructured campaigns for tighter targeting, so the same traffic cost less to buy.
Reallocate to what converts
Moved the freed budget to the campaigns that were converting well, so the money that left the weak campaigns went to work in the strong ones.
03The results
Comparing Oct 1-9 with Sept 22-30, TACoS improved from 21.95% to 14.40%, a drop of 7.55 percentage points (34.4%). Sales moved from $85.7K to $104.6K while advertising cost fell from $18.8K to $15.1K.
In dollar terms that is about $3.75K less spent on advertising alongside $18.86K more in sales. These are two separate 9-day windows compared against each other, not a day-by-day trend.
Why it worked: the account did not need more spend, it needed less waste in the spend it already had. Cutting irrelevant traffic and high-ACOS campaigns first, then reallocating, is what let sales rise while the ad bill fell.
04FAQ
How do you lower TACoS on Amazon without losing sales?
Remove waste before you reallocate. On this beauty and personal care account, negative keywords, bid optimization, campaign restructuring and pausing high-ACOS campaigns took TACoS from 21.95% to 14.40% while sales grew from $85.7K to $104.6K across two 9-day windows.
What is the Waste-Out Reallocation?
A three-step sequence: (1) cut waste with negative keywords and by pausing high-ACOS campaigns; (2) lower click cost with bid optimization and tighter campaign structure; (3) move the freed budget to campaigns that already convert.
What is TACoS and why does it matter?
TACoS is total advertising cost of sales: ad spend divided by total sales, not just ad-attributed sales. It shows how much of your whole revenue the ads are costing you, so a falling TACoS with rising sales means growth is getting cheaper.
Is this a trend or a before and after?
A before and after. The result compares two separate 9-day windows, Sept 22-30 and Oct 1-9. It does not show a daily progression inside either window.
