SEO Migration Planner & Monitor

Purpose

Comprehensive site migration planning and post-migration monitoring for SEO: crawl-based URL inventory, traffic/keyword baseline capture via our-seo-agent CLI, redirect map generation with per-URL risk scoring, pre-migration checklist creation, and post-launch traffic/indexation/ranking recovery tracking with automated alerts. Supports domain moves, platform changes, URL restructuring, HTTPS migrations, and subdomain consolidation.

Core Capabilities

1. URL Inventory - Crawl entire site via Firecrawl to capture all URLs and status codes
2. Traffic Baseline - Capture per-page traffic, keywords, and backlinks via our-seo-agent CLI
3. Redirect Map Generation - Create old URL -> new URL mappings with 301 redirect rules
4. Risk Scoring - Score each URL (0-100) based on traffic, backlinks, and keyword rankings
5. Pre-Migration Checklist - Generate type-specific migration checklist (Korean)
6. Post-Migration Traffic Comparison - Compare pre vs post traffic by page group
7. Redirect Health Check - Detect broken redirects, chains, and loops
8. Indexation Tracking - Monitor indexed page count changes and missing pages
9. Ranking Monitoring - Track keyword position changes for priority keywords
10. Recovery Estimation - Estimate traffic recovery timeline based on migration type
11. Alert Generation - Flag traffic drops >20%, broken redirects, indexation loss

MCP Tool Usage

Workflow

Pre-Migration Planning

1. Accept target domain, migration type, and new domain (if applicable)
2. Crawl URL inventory via Firecrawl (capture all URLs + status codes)
3. Fetch top pages baseline via our-seo-agent CLI or pre-fetched data
4. Fetch site-level metrics (total traffic, keywords, referring domains)
5. Enrich URL inventory with traffic/backlink data from our-seo-agent CLI
6. Score risk per URL (0-100) based on traffic weight (40%), backlinks (30%), keywords (30%)
7. Generate redirect map (old URL -> new URL) based on migration type
8. Aggregate risk assessment (high/medium/low URL counts, overall risk level)
9. Generate pre-migration checklist (common + type-specific items, in Korean)
10. Save baseline and plan to Notion

Post-Migration Monitoring

1. Accept domain, migration date, and optional baseline JSON
2. Compare pre vs post traffic using our-seo-agent metrics history
3. Check redirect health via Firecrawl (broken, chains, loops)
4. Track indexation changes (pre vs post page count, missing pages)
5. Track keyword ranking changes for priority keywords
6. Estimate recovery timeline based on traffic delta and migration type
7. Generate alerts for significant issues (traffic >20% drop, broken redirects, etc.)
8. Save monitoring report to Notion

Risk Scoring Methodology

Factor	Weight	Scale
Traffic	40%	1,000+ monthly visits = high risk
Backlinks	30%	50+ referring domains = high risk
Keywords	30%	20+ keyword rankings = high risk

Priority Classification

Risk Score	Priority	Action
75-100	Critical	Manual redirect verification required
50-74	High	Priority redirect with monitoring
25-49	Medium	Standard redirect
0-24	Low	Batch redirect

Alert Thresholds

Alert Type	Threshold	Severity
Traffic drop	>20%	warning; >40% critical
Broken redirects	>0	warning; >10 critical
Redirect chains	>0	warning
Indexation loss	>10%	warning; >30% critical
Ranking drop	>5 positions (volume 100+)	warning; >20 keywords critical

Limitations

• Data freshness depends on source and collection method
• Firecrawl crawl limited to 5,000 URLs per run
• Redirect chain detection depends on Firecrawl following redirects
• Recovery estimation is heuristic-based on industry averages
• URL restructuring requires manual mapping rules (no auto-pattern detection)
