How do you redesign a website without losing SEO rankings?
Audit your current pages and traffic first, keep the URLs and content that perform, map every old URL to a new one with a 301 redirect, carry over titles, headings, structured data and internal links, test the new site before launch, submit the new sitemap and watch search data closely for the first 90 days.
Before you redesign
- Set goals: more leads, better speed, clearer messaging or easier editing.
- Record your baseline: traffic, rankings, conversions and Core Web Vitals.
- Crawl the current site and list every page and URL.
- Mark pages that bring traffic or links, because these are the pages to protect.
- Decide what to keep, improve, merge or remove.
Protect your URLs
Every change of address risks lost rankings. Keep URLs the same wherever you can. Where you must change them, map each old URL to its closest new page and set up a 301 redirect. Avoid redirect chains and never send many old pages to the home page.
| Situation | What to do |
|---|---|
| URL stays the same | Do nothing. This is the safest option. |
| Page moves | 301 redirect to the new URL. |
| Pages merge | 301 redirect each old URL to the merged page. |
| Page removed | Redirect to the closest relevant page, or return a proper 404 or 410. |
Content and on-page SEO
- Keep titles, descriptions and headings that already perform, and improve weak ones.
- Put a clear answer to the main question near the top of key pages.
- Keep structured data such as Organization, Service, FAQ and Article, and check it matches the visible text.
- Maintain internal links between related pages.
- Add descriptive alt text to images.
Technical checks
- Speed: aim to pass the Core Web Vitals thresholds, as explained in our Core Web Vitals guide.
- Mobile: test layouts, tap targets and forms on real phones.
- Accessibility: check contrast, headings, labels and keyboard use.
- Indexing: make sure the staging site is blocked and the live site is not.
- Server-rendered HTML so search engines and AI assistants can read the content.
Launch and the first 90 days
- Launch at a quiet time and re-test redirects, forms and tracking.
- Submit the new sitemap in Google Search Console and Bing Webmaster Tools.
- Check the coverage report for errors and fix them quickly.
- Compare traffic and rankings with your baseline each week.
- Fix broken links and slow pages as they appear.
Key takeaway: A redesign is not finished at launch. Treat the first 90 days as part of the project and monitor results every week.

Should I change my URLs in a redesign?
Only when there is a strong reason. Keeping URLs the same is the safest route.
How long until I see results?
Search engines re-evaluate pages over weeks. Track results for at least 90 days.
Can I redesign in phases?
