Slack and webhook rank alerts

Alert rules turn rank tracking from "I check the dashboard sometimes" into "I get pinged only when something matters". Three destinations: Slack, email, webhook.

Create a rule

1. Rank Tracking → Alerts → New rule.
2. Scope: all keywords, a group, or specific keywords.
3. Trigger: movement of N positions, crossing a threshold (e.g. drops out of top 10), or a SERP feature event.
4. Destination: Slack channel, email address(es), webhook URL.
5. Schedule: instant, daily digest, weekly digest.
6. Save.

Trigger types

Slack message format

Every alert includes: keyword, location, device, old position, new position, delta with arrow emoji, and a deep link to the keyword detail view. Daily/weekly digests group all events into one threaded message.

Webhook payload

{
  "event": "keyword.moved",
  "occurred_at": "2026-05-30T08:00:00Z",
  "data": {
    "keyword_id": "kw_42",
    "keyword": "seo audit tool",
    "location": "Sydney NSW",
    "device": "mobile",
    "engine": "google",
    "old_position": 12,
    "new_position": 6,
    "delta": 6,
    "url": "https://app.semoptimiser.com/dashboard/rank-tracking/kw_42"
  }
}

Aggregation and throttling

In digest modes, all matching events from the digest window are bundled into one message. Instant mode is rate-limited to one alert per (rule, keyword) per hour to prevent flapping on borderline cases.

Multi-destination routing

Common pattern with three rules:

• #seo-wins ← positive movement of 5+ (any kw enters top 3).
• #seo-emergency ← negative movement of 5+ OR drops out of top 10.
• #seo-daily-digest ← everything else, daily at 9am.

Pause / disable

Each rule has a toggle. Pause during planned site migrations or major content launches to avoid noise.
