• Develop redirect mapping strategies to preserve rankings and traffic post-migration.
• Perform thorough post-migration monitoring to identify and resolve traffic or ranking drops.
• Collaborate with developers, content teams, and stakeholders to ensure SEO best practices are followed throughout the migration process.

About You:

• 3+ years of experience in a technical SEO role, ideally in an agency or enterprise setting.
• Experience with SEO tools (Screaming Frog, Ahrefs, SEMrush, DeepCrawl, Sitebulb, Google Search Console etc.).
• Hands-on experience with Google Tag Manager, Google Analytics 4, and Looker Studio.
• Solid understanding of server-side factors, including log file analysis and server response codes.
