Key takeaways

  • Pre-launch inventory and baseline data are non-negotiable for measuring success.
  • 301 redirects must be mapped, tested, and deployed before the redesign goes live.
  • Post-launch monitoring for 30 days is critical to catch errors early.
  • Never index staging or test environments by mistake.

Common Mistakes

  • Launching without a redirect map: leads to massive 404s and traffic loss.
  • Forgetting to update internal links: users and crawlers rely on redirects, slowing down performance.
  • Leaving staging environment indexable: causes duplicate or thin content issues.
  • Skipping post-launch monitoring: minor issues can snowball into major ranking drops.
  • Changing URL structure without updating XML sitemap: search engines may miss new pages.
