# Read sitelinks and asset extensions performance

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

Extension assets via GAQL: sitelinks, callouts, snippets, with serve and click shares.

**Intent.** Whether the extensions earn their slots.

## When to use

- Quarterly hygiene.
- After extension revamps.

## When not to use

- No specific contraindication beyond the preconditions below.

## Sources

Required: Google Ads

## Preconditions

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

## Inputs

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

## Procedure

1. Query asset performance across types. — tools: `google_ads_run_gaql`
2. Flag empty or stale slots per campaign.

## Decision rules

- **When** Campaigns run without full extension coverage → **conclude** Free SERP surface unclaimed: list the gaps, cheapest fixes in the account.

## 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

- Extension clicks double-count with ad clicks in some views: name the metric used.

## Output

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