What it does
Catches unusual performance changes across your accounts — CPC spikes, CVR drops, spend surges, impression collapses, CTR shifts — and flags them with context about what likely changed. The goal is to catch problems in hours instead of discovering them days later during a routine check.
How it works
Claude compares current performance against your recent baseline (typically 7-14 day rolling average) and flags any metric that moves beyond a threshold you set. It then cross-references the anomaly against common causes — budget changes, auction shifts, ad disapprovals, audience exhaustion, landing page issues, or external events.
Practical example
Thursday at 2pm, your branded search CPC jumps 47% compared to the 14-day average. Claude flags it and identifies that a competitor started bidding on your brand terms (impression share dropped from 94% to 71% simultaneously). It also catches that a Meta campaign's CVR dropped 60% — the landing page started returning 404 errors after a site deployment at 1:30pm.
What you get back
List of anomalies ranked by financial impact (estimated wasted or lost spend)
Each anomaly paired with the most likely cause based on correlated data shifts
Recommended immediate actions for each issue
Severity rating so you know what to fix now vs what can wait
Baseline comparison data so you can see exactly how far off normal the metric is
When to use it
Daily monitoring across all active accounts
After website deployments or landing page changes
During high-spend periods like Black Friday or product launches
When managing multiple accounts and you can't manually check everything daily
