ACOS wobbled through a mid-year test before settling back down, while TACOS and daily run rate improved through the same window.
This is a live Amazon Ads account in the Stationery category, reported over May to August. Stationery has clear seasonal peaks, and the account ran a test through the middle of the year to see how much more it could scale.
Tests do not always go in a straight line, and we think it is useful to show one that did not.
Spend grew by 44% across the window, a more measured increase than in some of our other accounts.
In August the account was credited with about ₹4.22 of ad-attributed sales for every ₹1 spent, roughly a 24% ACOS.
Total sales grew 55%, ahead of the 44% increase in spend.
ACOS wobbled through the mid-year test before settling back down. Over the same window, TACoS and the daily run rate improved.
Sales growth finished ahead of spend growth, which suggests the extra investment was productive overall, even though the path included a rough patch.
What happens next. Next steps focus on holding the improved run rate and identifying which of the test's additions are worth keeping permanently.
