# Read how SERP features change your clicks

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

Search appearance trends read for the CTR-without-rank-change cases.

**Intent.** Whether rich results and features move CTR independent of rank.

## When to use

- CTR moved while positions held.
- After schema work ships.

## When not to use

- No specific contraindication beyond the preconditions below.

## Sources

Required: Search Console

## Preconditions

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

## Inputs

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

## Procedure

1. Analyse appearance trends over the window. — tools: `gsc_analyze_search_appearance_trends`
2. Tie feature gains and losses to the affected page sets.

## Decision rules

- **When** A feature loss coincides with the CTR drop at stable position → **conclude** The SERP changed around the page: feature work, not content work.

## 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

- Feature reporting granularity is coarse: date alignments are approximate.

## Output

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