The phase-by-phase checklist
Phase 1: Full crawl & URL map
Key activities, deliverables and sign-off criteria for this stage — treat each phase as its own mini-plan with clear exit criteria.
Phase 2: 301 redirect plan
Key activities, deliverables and sign-off criteria for this stage — treat each phase as its own mini-plan with clear exit criteria.
Phase 3: Technical SEO checklist
Key activities, deliverables and sign-off criteria for this stage — treat each phase as its own mini-plan with clear exit criteria.
Phase 4: Migration execution
Key activities, deliverables and sign-off criteria for this stage — treat each phase as its own mini-plan with clear exit criteria.
Phase 5: Post-launch monitoring
Key activities, deliverables and sign-off criteria for this stage — treat each phase as its own mini-plan with clear exit criteria.
Budget and resources
Budget by phase, not lump sum — each phase above gets its own estimate, owner and approval. Build 15-20% contingency; seo migration projects historically overrun where the phases blend together.
Common risks in seo migration projects
- Ranking drops from bad redirects: the top failure mode — mitigate in the plan, not in the crisis.
- Scope creep: additions mid-project — route through change control.
- Dependencies: external items (vendors, approvals) — schedule with buffer.
