Will a website redesign kill our SEO?
A redesign won't kill your SEO if you treat it as a migration, and it usually does damage for one of a handful of reasons that are all preventable. Search engines don't mind a new design. They mind URLs that change without a redirect, pages that ranked and then disappear, and a staging noindex tag that ships to production. Get those right and most sites see a small wobble for a couple of weeks and then hold or improve.
We rebuild sites for funded startups in two to four weeks, so we see the panic before a launch more than most. This is the checklist we work from.
What actually causes traffic to drop after a redesign?
Almost every bad migration we've looked at comes down to one of these.
| Mistake | What it does | The fix |
|---|---|---|
| URLs change with no redirects | Every ranking page turns into a 404 | Map every old URL to its closest new page with a 301 |
| Pages that ranked are cut | The traffic and links they earned go with them | Keep or merge them, never delete them without a redirect |
| Staging noindex ships live | Google drops the whole site from results | Check the robots meta and robots.txt on launch day |
| Titles and headings on top pages are rewritten | Pages lose the words they were ranking for | Keep the target phrase on pages that already rank |
| Content moves into scripts or images | Crawlers can't read what they can't see | Keep important copy as real HTML text |
| Internal links disappear from the new nav | Pages lose their route in, and Google stops finding them | Rebuild the links that pointed at important pages |
| The new site is slower | Worse page experience, especially on mobile | Compress images, lazy-load video, test before launch |
The first three cause most of the damage. The rest decide whether you hold your position or slowly slide.
What should you do before launch?
Make a list of every URL you have today. Crawl the current site, then export every page with impressions from Google Search Console over the last six months, plus any page other sites link to. That's your inventory, and anything on it needs a home on the new site.
Then build a redirect map, one row per old URL, pointing at the closest new page. Don't send everything to the homepage, because Google treats mass homepage redirects much like missing pages. While the new site is on staging, keep it behind a password or a noindex tag so it can't be indexed early, and write down that you've done it so someone remembers to take it off.
What should you check on launch day?
Work through this list in the first hour.
- Remove the noindex and check robots.txt allows crawling.
- Test a sample of old URLs and confirm each one 301s to the right page.
- Check canonical tags point at the live domain, not staging.
- Submit the new sitemap in Google Search Console and Bing Webmaster Tools.
- Use URL Inspection on your five most important pages and request indexing.
- Crawl the live site for broken links and 404s.
What should you watch afterwards?
Watch Search Console for four to eight weeks. A dip of a week or two is normal while Google recrawls, and the thing to look for is pages that stay missing or a rise in 404 errors. Fix those as they appear, and compare your top pages' clicks and positions with the same period before launch.
When we merged two duplicate pages on our own site this month, each one got a 301 to the closest page, every link pointing at them was updated and they came out of the sitemap the same day. It took ten minutes, and it's the same discipline a full redesign needs, just at a bigger scale.
Does changing platform make a difference?
Moving between Framer, Webflow and a custom build is fine for SEO as long as the URLs, content and redirects come with you. All three can set 301s and output proper HTML. The risk is in the move itself, not the platform you land on.
If you're changing domain as well, do it as a separate step where you can, because a new domain and a new site at the same time makes it much harder to see what caused any drop.
Website redesign SEO FAQ
How long does it take for rankings to recover after a redesign?
If the redirects and content are right, most sites settle within two to six weeks. If rankings are still down after two months, something went missing in the move, and Search Console's page indexing report is the place to find it.
Should we keep the same URLs when we redesign?
Where you can, yes, because keeping URLs on the pages that already rank is the safest option. Where the structure has to change, a clean 301 from each old URL to its closest new page carries most of the value across.
Does a new design affect rankings on its own?
Not really, because Google ranks content, links and page experience. A new design that keeps the content, keeps or redirects the URLs and loads quickly shouldn't hurt, and a faster, clearer site often helps.
Who should own the redirect map?
Whoever builds the site, signed off by whoever owns your search traffic. If your agency doesn't mention redirects before launch, ask them for the map in writing.
