The goal is to catch problems in hours instead of discovering them days later during a routine check.</p>\n<h2>How it works</h2>\n<p>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.</p>\n<h2>Practical example</h2>\n<p>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.</p>\n<h2>What you get back</h2>\n<ul>\n<li>List of anomalies ranked by financial impact (estimated wasted or lost spend)</li>\n<li>Each anomaly paired with the most likely cause based on correlated data shifts</li>\n<li>Recommended immediate actions for each issue</li>\n<li>Severity rating so you know what to fix now vs what can wait</li>\n<li>Baseline comparison data so you can see exactly how far off normal the metric is</li>\n</ul>\n<h2>When to use it</h2>\n<ul>\n<li>Daily monitoring across all active accounts</li>\n<li>After website deployments or landing page changes</li>\n<li>During high-spend periods like Black Friday or product launches</li>\n<li>When managing multiple accounts and you can't manually check everything daily</li>\n</ul>\n<h2>Data access (Ryze MCP)</h2>\n<p>This skill works best with live account data.
