What a GSC anomaly detector has to do

Connect GSC → Slack/email when queries/pages drop.

• Drop email: Clicks or impressions off a baseline — not a 400-alert firehose.
• Page + query: Which URL and which query moved.
• CSV tryout: No OAuth required to see a sample from an export.
• Slack: Pro posts the anomaly, not a 'visibility dipped' toast.
