Deployment Control list

Introduction

A deployment checklist is a systematic tool for quality assurance when publishing website changes. It ensures that all SEM-relevant aspects are checked before, during, and after a deployment to avoid ranking losses and technical issues.

• Save time - Avoid subsequent corrections and rollbacks
• Team coordination - Define clear responsibilities and processes
• Documentation - Traceability of all measures taken
