A store redesign can quietly destroy years of SEO in a single launch — broken URLs, lost redirects, vanished product pages. None of it is inevitable. It is a checklist problem, not a luck problem.
Why redesigns are risky for SEO
Search engines rank specific URLs, not just your brand. Replatforming — say, moving from one e-commerce platform to another — often changes URL structure, product IDs and page templates all at once. If the old URLs simply stop existing, you lose the rankings, links and trust built up against them, not just the old design.
301 redirects and preserving URL structure
- Crawl and export every existing indexed URL before touching anything.
- Map each old URL to its exact new equivalent — product to product, category to category.
- Set up 301 (permanent) redirects for every mapped pair, not a blanket redirect to the homepage.
- Keep the same URL structure where possible; only change it if there is a genuine reason to.
Staging audits and the post-launch checklist
Run the redirect map and a full technical SEO audit on a staging environment before it goes live — broken links, missing meta tags, duplicate content and redirect chains are far cheaper to fix before launch than after Google has recrawled the new site.
- Compare a before/after crawl: title tags, meta descriptions, headings, structured data all present.
- Verify every redirect actually resolves — a redirect map with typos is as bad as no map.
- Check the XML sitemap reflects the new URLs and is resubmitted to Search Console.
- Watch rankings, crawl errors and organic traffic closely for the first two to four weeks after launch, and fix issues immediately, not on the next sprint.
