Website redesign without losing rankings: a migration checklist.

Why a website redesign can hurt rankings

A website redesign is one of the riskiest things you can do to your search traffic, and one of the most valuable when it's done well. Rankings drop after a redesign for a small number of predictable reasons.

• URLs change and the old ones aren't redirected, so search engines and visitors hit 404 errors.
• Content that ranked well is cut, shortened or merged without a plan.
• Titles, headings and internal links change, weakening the signals that made pages relevant.
• The staging site's "noindex" setting goes live, telling search engines to drop the whole site.
• The new design is slower or relies on JavaScript in ways that make content harder to crawl.

Every one of these is avoidable. The checklist below is the process we follow on every website redesign, split into the work before, during and after launch.

Before the redesign: benchmark everything

You can't protect what you haven't measured. Before design work starts, capture a complete picture of the current site.

1. 1. Crawl the current site. Use a crawler such as Screaming Frog to export every URL, title, meta description, H1 and status code.
2. 2. Export your top pages. From Google Search Console and analytics, list the pages that bring the most clicks, impressions and conversions over the last 12 months.
3. 3. Record your rankings. Note positions for your most important keywords so you can compare after launch.
4. 4. List your backlinks. Identify pages with external links pointing at them. These URLs must be preserved or redirected.
5. 5. Save the old site. Keep a full backup and a crawl export. You will refer back to them.

During planning: map every URL

The URL map is the single most important document in a website redesign. It lists every old URL and where it will live on the new site.

1. 6. Keep URLs where you can. If a page is staying, keeping its URL is the safest option of all.
2. 7. Map changed URLs one to one. Each old URL should redirect to its closest new equivalent, not to the homepage.
3. 8. Use 301 redirects. Permanent redirects tell search engines the move is permanent and pass on the old page's signals.
4. 9. Avoid redirect chains. Point old URLs straight at their final destination, and update any existing redirects too.
5. 10. Protect high-performing content. Pages that rank should keep their substance, even if the design changes completely.

Google's guide to site moves with URL changes (opens in a new tab) is the definitive reference here, and worth reading before any migration.

During the build: carry the SEO across

1. 11. Block the staging site. Password-protect it, so search engines can't index a duplicate of your website.
2. 12. Carry over metadata. Move titles and meta descriptions for every page, then improve them deliberately, not by accident.
3. 13. Keep heading structure. One H1 per page, with logical H2s and H3s that reflect what the page is about.
4. 14. Rebuild internal links. Navigation, footer and in-content links should point to the new URLs directly, not through redirects.
5. 15. Keep structured data. Recreate Organization, Service, FAQ and product schema, and test it before launch.
6. 16. Check speed and accessibility. Test Core Web Vitals and WCAG 2.2 AA on staging, while fixes are still cheap.

Launch day: the website redesign go-live checks

Launch day is when small mistakes become expensive. Work through these checks within the first hour of going live.

1. 17. Remove noindex and staging restrictions. Check the robots meta tag on several pages, and confirm robots.txt doesn't block the site.
2. 18. Test your redirects. Run your old URL list through a crawler and confirm every one returns a 301 to the right page.
3. 19. Submit your XML sitemap. Submit the new sitemap in Google Search Console and Bing Webmaster Tools.
4. 20. Test forms and tracking. Submit every form, check confirmation emails, and confirm analytics and conversion tracking fire correctly.

If your domain is changing too, use the Change of Address tool in Search Console once redirects are live.

After launch: the first 90 days

21. Monitor closely. Some movement in rankings is normal for a few weeks after a website redesign while search engines re-crawl the site. What matters is the trend.

• Check Search Console daily for the first week for crawl errors, 404s and indexing issues.
• Compare clicks and impressions for your top pages against the benchmark you recorded.
• Fix any 404s that appear by adding redirects or restoring content.
• Keep redirects in place for at least a year, and ideally permanently.

If traffic to a specific page drops and doesn't recover after a few weeks, compare the old and new versions. Usually something important was removed: a section of content, a heading, or the internal links that pointed to it.

The short version

A website redesign doesn't have to cost you rankings. Benchmark the old site, map every URL to a new home with 301 redirects, carry your best content and metadata across, block staging, check everything on launch day and monitor for 90 days. Done properly, a redesign is usually the start of better rankings, not the end of them.

Frequently asked questions

How long do rankings take to settle after a website redesign?

With redirects and content handled properly, most sites see rankings settle within a few weeks. Larger sites can take a few months while search engines re-crawl every URL.

Should I change my URLs during a website redesign?

Only when there's a clear benefit, such as a confusing structure or URLs full of dates and IDs. Every changed URL needs a redirect and takes time to be re-processed, so keep URLs that already work.

Do 301 redirects lose SEO value?

Google has said that redirects don't cause a loss of ranking signals. They still take time to be processed, which is why short-term movement after launch is normal.

How long should I keep redirects in place?

Google recommends keeping redirects for at least a year. We recommend keeping them permanently, because old links in emails, bookmarks and other websites keep working.

Can I change my domain and redesign at the same time?

You can, but it doubles the risk and makes problems harder to diagnose. Where possible, move the domain first or redesign first, and let things settle in between.
