Quick Takeaway
To redesign a website without losing SEO, keep your existing URLs where you can, and permanently redirect (301 or 308) every old URL that changes to its closest new page. Carry over the content, titles and descriptions that already rank, test the new site before launch, then submit the new sitemap and watch Search Console. Google says rankings may fluctuate for a few weeks during a move.
Key takeaways
- Start with an inventory of the pages that bring traffic, leads and links; those must survive the redesign.
- Keep URLs unchanged when possible; otherwise map every old URL to its new one and use permanent server-side redirects (301 or 308).
- Google recommends keeping redirects for at least a year and redirecting straight to the final URL, without chains.
- Don't drop the content, titles, headings and internal links that made pages rank.
- After launch, submit the new sitemap, fix errors in Search Console and Bing Webmaster Tools, and expect a few weeks of fluctuation.
A redesign is meant to bring more customers, but many businesses launch a beautiful new site and watch their Google traffic fall the same month. The cause is almost never the new design itself. It’s the things that quietly disappeared: old URLs that now return errors, pages that were merged or deleted, and text that ranked but was cut for a cleaner look.
This checklist follows Google’s own guidance on site moves, checked in October 2026, plus what we do on every web development project that replaces an existing site.
- Site migration
- A site migration is any change that moves pages to new URLs, a new domain, a new platform or a new structure. A redesign that keeps every URL and only changes the look is low-risk; a redesign that changes URLs is a migration and needs redirects.
Step 1: Inventory what already works
Before anyone designs anything, export a list of every URL on the current site and mark the ones that matter:
- Pages with clicks and impressions in Google Search Console (Performance report, Pages tab) over the last 12 months.
- Pages that bring leads or sales in your analytics.
- Pages other websites link to (Search Console’s Links report shows your top linked pages).
- The search queries each important page ranks for, so you can check them after launch.
Save a “before” snapshot
Export Search Console performance data and a crawl of the old site before launch. Without a baseline you can’t tell whether a drop after launch is normal fluctuation or a real problem.
Step 2: Keep URLs, or map every change
The safest redesign keeps the same URLs. If the structure must change, Google’s site-move guide says to map each old URL to its new URL and use server-side permanent redirects from old to new.
| Old URL | New URL | Action |
|---|---|---|
| /services.html | /services/ | 301 redirect |
| /web-design-services/ | /services/web-design/ | 301 redirect |
| /blog/2019/tips-post/ | /blog/tips-post/ | 301 redirect |
| /old-promo-2021/ | none (no equivalent page) | Redirect to the closest relevant page, or let it return 404 if nothing fits |
- Use permanent redirects: Google recommends 301 or 308 server-side redirects where possible.
- Redirect to the final URL: avoid chains such as A → B → C; point A straight to C.
- Keep redirects in place: Google says generally at least one year, and longer is fine.
- Don’t send everything to the home page: redirect each page to its closest equivalent so its relevance carries over.
Step 3: Protect the content that ranks
Rankings come from content, not layout. When a page that ranks is redesigned, keep:
- The main text, or improve it; don’t replace it with a short slogan and an image.
- The title tag and meta description, unless you have a clear reason to change them.
- The heading structure (one H1, logical H2s) and the questions the page answers.
- Image alt text, structured data and FAQ sections.
- Internal links pointing to the page from other pages and menus.
Step 4: Test the new site before launch
Build and test on a staging site that search engines can’t index (password-protect it), then check before switching:
- Every redirect in your map works and lands on a page that returns 200.
- No broken internal links or images.
- Each page has a self-referencing canonical tag pointing to its new URL.
- robots.txt allows crawling and no page has a leftover noindex tag from staging.
- Pages load fast and work on phones.
- Forms, booking and analytics tracking work.
- A new XML sitemap lists only the new, live URLs.
The most common launch mistake
A staging “noindex” tag or a robots.txt “Disallow: /” copied to the live site can remove it from Google entirely. Check both on launch day.
Step 5: Launch and tell search engines
Step 1: Switch on redirects with the launch
Redirects should go live at the same moment as the new site, not days later.
Step 2: Submit the new sitemap
Submit it in Google Search Console and Bing Webmaster Tools. Google says you can remove the old sitemap once the new one is being used.
Step 3: Update internal links
Point menus and in-text links straight to the new URLs instead of relying on redirects.
Step 4: Update external profiles
Change links on your Google Business Profile, social profiles and directories you control.
Step 5: Only use Change of Address for a new domain
Google’s Change of Address tool is for moving to a different domain. It isn’t for HTTP to HTTPS, for www vs non-www, or for moving pages within the same site.
Step 6: Monitor the first weeks
Google says that for a medium-sized site it can take a few weeks or more before it shows the new URLs, and visibility may fluctuate temporarily during the move. Check weekly:
- Search Console’s Pages (indexing) report for new 404s and redirect errors.
- Performance for your top pages and queries, compared with your “before” snapshot.
- Crawl errors and your sitemap status in Bing Webmaster Tools.
- Leads and conversions in analytics, which matter more than rankings.
If a page that used to rank has dropped and stays down after several weeks, compare it with the old version: missing text, a changed title or a broken redirect is usually the reason. Our technical SEO checklist covers the technical checks in more depth.

Will a website redesign hurt my SEO?
It doesn’t have to. Rankings usually drop because URLs change without redirects, ranking content is removed, or the new site is accidentally blocked from search engines. Keep URLs or redirect them, keep the content that ranks, and test before launch.
Should I use 301 or 302 redirects for a redesign?
Permanent ones. Google recommends server-side permanent redirects (301 or 308) when URLs change for good. Temporary redirects (302 or 307) are for short-term changes.
How long should I keep redirects after a redesign?
Google recommends keeping them generally for at least one year, and they can stay in place indefinitely. Update your own internal links to the new URLs so visitors don’t go through redirects.
How long does it take for rankings to recover after a redesign?
Google says a medium-sized site can take a few weeks or more for the new URLs to be shown, with temporary fluctuation during the move. Larger sites can take longer.
Do I need Google’s Change of Address tool for a redesign?
Only if you are moving to a different domain. For changes within the same domain, including HTTP to HTTPS and www to non-www, use redirects and canonical tags instead.
