Website Relaunch Without Losing Google Rankings: The Checklist

A new design can make your website look great – and still destroy years of SEO work if the relaunch is done carelessly. Follow this checklist.

Before the relaunch

1. Crawl the old website and export every URL (tools like Screaming Frog).
2. Collect performance data: which pages bring traffic, rankings and backlinks (Google Search Console, analytics).
3. Decide what happens to each page: keep, merge, rewrite or remove.
4. Create a redirect map: every old URL gets a target URL on the new site.
5. Keep valuable content: don't shorten pages that rank well without reason.

During development

• Keep URL structures where possible.
• Carry over titles, meta descriptions and headings of strong pages.
• Implement 301 redirects for every changed URL – not just to the homepage.
• Set up structured data, XML sitemap and robots.txt.
• Check page speed and Core Web Vitals on the staging site.
• Block the staging site from search engines (and remember to unblock at launch!).

Launch day

• Activate redirects and test a sample of old URLs.
• Remove "noindex" and staging restrictions.
• Submit the new sitemap in Google Search Console.
• Check analytics and consent tracking are working.
• Test forms, checkout and key conversions.

After launch

• Monitor 404 errors and crawl errors daily for the first weeks.
• Compare rankings and organic traffic with the baseline.
• Fix missing redirects quickly.
• Update important backlinks if possible.
• Check that Google indexes the new pages.

Common mistakes

• Redirecting everything to the homepage
• Forgetting image and PDF URLs
• Changing many things at once (domain, URLs and content) without a plan
• Launching with "noindex" still active

A short dip in rankings can happen after big changes, but with a clean migration it recovers quickly. We include this checklist in every redesign project.
