When to use it

Use it when

  • Quarterly.
  • Suspicion that one surface leaks spend.

Do not use it when

  • No specific contraindication beyond the preconditions below.

What it needs first

Required

Preconditions

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

Inputs

window
Analysis window.Default: last 30 days.

Procedure

In order. Every tool named is one the gateway ships, and links to its reference.

  1. Pull insights broken down by placement.

  2. Compare cost share to result share per placement.

Decision rules

The observable condition, what it lets you conclude, and what takes the conclusion back.

  • When

    A placement takes cost share far above result share at volume

    Conclude

    Exclusion candidate: size the reallocation, propose via Safe Writes.

Evidence every conclusion must carry

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

Where the agent stops

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

How it goes wrong quietly

The cases where the analysis is wrong and still looks right. Read them before trusting a number.

  • Placement-level attribution is weaker than campaign-level: small gaps are noise, big ones are findings.
