# Read TikTok ad group performance inside a campaign

> Tier: recipe. Operating recipe: real tool sequence, core rules, known traps.

The ad-group level table: audiences, placements, optimisation goals, results.

**Intent.** Ad groups with targeting, placements and results for one campaign.

## When to use

- A flagged campaign needs its inside view.

## When not to use

- No specific contraindication beyond the preconditions below.

## Sources

Required: TikTok Ads

## Preconditions

- The account is ticked in the dashboard, confirmed via list_accounts.

## Inputs

- `window`: Analysis window. Default: last 30 days.

## Procedure

1. Pull ad groups with targeting summaries. — tools: `tiktok_get_adgroups`
2. Pull ad-group performance. — tools: `tiktok_get_insights`

## Decision rules

- **When** An ad group optimises to an event its pixel barely fires → **conclude** It optimises toward noise: check events before judging the audience.

## Evidence requirements

- Every figure carries its account, metric and window.
- Anything below a readable sample size is reported as unjudged, not as zero.

## Human approval boundary

- The readout changes nothing. Any change it motivates goes through Safe Writes: preview, human confirmation, then apply.

## Failure modes

- Automatic placements hide the mix: placement conclusions need the breakdown, not the setting.

## Output

- **Readout**: The figures, with windows and accounts named.
- **Flags**: What deserves a deeper skill or a human decision.
