Trellis Managed: ACOS and Budget Manager- TACOS Based
What it looks at, what it flags, what it changes, what you can change.
- Total sales, ad sales and spend per category, over your lookback
- Categories with no sales at all, dropped before anything is computed
- Active advertisements with their budget, current ACoS and target ACoS
- Over Target, when TACoS runs above target by more than your tolerance
- Under Target, when it runs below by more than your tolerance
- Pure organic, where a category sells but carries no ad spend
- A derived Target ACoS per category, from its ad-to-total sales ratio
- Budgets down in over-target categories, up in under-target ones
- A daily step cap on both, so nothing moves far in one run
- Marketplace, lookback days, target TACoS
- Tolerance band and budget change percentage
- Changed on a run without touching the template

Frequently Asked Questions
Set a target TACoS and a tolerance band, and the skill computes rolling TACoS per category each day. Categories outside the band get a derived Target ACoS applied to all their active ads, plus a budget adjustment.
It is the ad-level ACoS target implied by your TACoS goal once a category's ad-to-total sales ratio is taken into account. Categories with more organic sales can carry a looser ad-level target and still hit the same TACoS.
It changes them. It applies the derived Target ACoS to every active advertisement in an off-target category, and updates those daily budgets in the same run.
How do I stop automated bid and budget changes running away?
The skill flags those as Pure Organic and lists them separately in the status report, marked No Action. Use that list to decide where campaign coverage is missing.
All of them — Over Target, Under Target, On Target and Pure Organic — with each category's current TACoS, its delta from target, the derived target, and whether an update was applied that day.
Every one of these runs on your own account.
