Legacies is an independent digital product brand based in Bucharest, Romania, founded by Horia Stan and Alexandru Tălnaci, that builds websites, landing pages and web apps for businesses worldwide. A redesign changes more than the layout: URLs, content and technical settings can all affect search traffic.
You do not have to. Most traffic lost after a redesign comes from a few fixable mistakes: URLs that change without redirects, pages that lose their content, and a staging setting left switched on. If you record what ranks today, redirect every changed URL to its closest match and check the new site the day it goes live, rankings usually dip briefly and then settle.
Quick answer
- Before: export every URL, its traffic and its rankings from Google Search Console. This is your baseline.
- During: keep URLs the same where you can. Where you cannot, map each old URL to one relevant new page with a permanent (301 or 308) redirect.
- Launch day: check for leftover "noindex" tags, broken redirects, missing titles and a fresh sitemap.
- After: watch Search Console for at least 4-8 weeks. Keep the redirects for at least a year, as Google recommends.
Why redesigns lose rankings
Google ranks pages, not websites. A page earns its position with its URL, its content, its title, the links pointing to it and how well it works for visitors. A redesign can quietly break any of those.
Here are the usual causes, roughly in the order we see them:
| Cause | What happens | How common |
|---|---|---|
| Changed URLs with no redirects | Old pages return 404 and lose their rankings and backlinks | The most common by far |
| Content cut "to look cleaner" | Pages lose the text that matched what people searched for | Very common |
| Staging "noindex" left on | Google is told not to index the new site | Rare, but it can wipe out traffic overnight |
| All old URLs redirected to the home page | Google treats them as soft 404s and drops them | Common with quick migrations |
| Titles and meta descriptions reset | Template defaults replace text that was already working | Common |
| Slower pages | Heavy sliders, video and scripts hurt Core Web Vitals | Common with template redesigns |
| Lost internal links | Menus and footers get shorter, so deep pages become orphans | Often missed |
None of these are about design. A new look is fine. Changing what Google already understands, without telling it, is the problem.
Before the redesign: record what you have
You cannot protect traffic you have not measured. Do this before anyone opens a design tool.
Export your top pages and queries
In Google Search Console, open Performance, set the range to the last 12 months and export both the Pages and the Queries tabs. If you do not have Search Console set up, that is the first fix. Our guide on why a website does not show up on Google walks through it.
Mark the pages that bring clicks, leads or sales. These are the pages you cannot afford to lose.
Crawl the current site
Get a full list of URLs, including ones that are not in the menu: old blog posts, PDFs, landing pages from past campaigns. A crawler such as Screaming Frog SEO Spider does this, and its free version crawls up to 500 URLs at the time of writing. Save each page's title, meta description, H1 and word count. That snapshot lets you compare old and new pages side by side later.
Check your backlinks
Pages that other sites link to carry authority. Search Console's Links report shows your most-linked pages. Every one of them needs a redirect if its URL changes.
During the redesign: protect URLs and content
Keep URLs the same where you can
The cheapest redirect is the one you never need. If /services/plumbing ranks, keep it as /services/plumbing on the new site, even if the new design would suggest another structure. Change a URL only when the page's purpose really changes.
Moving platforms makes this harder. Shopify forces /products/ and /collections/ paths, and Wix and Squarespace have their own patterns. That is a real cost of switching, and it should be in the quote. We compare platforms in WordPress vs Next.js for a business website.
Build a redirect map
Where URLs must change, make a simple spreadsheet: one column for the old URL, one for the new URL. Google's site move documentation gives clear rules:
- Use server-side permanent redirects (301 or 308). Client-side redirects are a last resort.
- Send each old URL to its most relevant new page. Do not send many old URLs to the home page.
- Avoid redirect chains. Point straight to the final address.
- Keep the redirects "for as long as possible, generally at least 1 year."
Every platform can do this. WordPress has redirect plugins. Shopify and Wix have built-in URL redirect managers. In Next.js, redirects live in the config file, and permanent: true sends a 308, as described in the Next.js redirects docs.
Here is an example of what a small map looks like (illustrative, not a real client):
| Old URL | New URL | Why |
|---|---|---|
| /our-services.html | /services | Same page, cleaner path |
| /plumbing-services | /services/plumbing | Moved under services |
| /blog/2019/winter-tips | /blog/winter-pipe-tips | Same article, new slug |
| /summer-promo-2023 | /services | Expired campaign, closest match |
| /team/old-employee | 410 Gone | No equivalent page |
The last row matters. If a page has no real equivalent and no backlinks, it is fine to let it go. A forced redirect to an unrelated page helps nobody.
Keep the content that ranks
Redesigns often come with a "less text, more white space" brief. That is fine on pages that never ranked. On pages that do rank, keep the substance: the headings, the questions they answer, and the details that matched the searches in your Search Console export. You can rewrite for clarity. Just do not cut the parts Google was matching to queries.
Carry over titles and meta descriptions from your crawl, then improve them on purpose, not by accident.
Do not make the site slower
A redesign is the best moment to get faster, and the easiest moment to get slower. Google's Core Web Vitals set "good" thresholds at a Largest Contentful Paint of 2.5 seconds or less, an Interaction to Next Paint of 200 ms or less, and a Cumulative Layout Shift of 0.1 or less. Autoplay hero videos, big uncompressed images and five tracking scripts will push you past them. Test the staging site, not only the old one.
Keep structured data and AI-readable structure
If the old site had schema markup (LocalBusiness, Product, FAQ, Article), the new one needs it too. Clear headings, direct answers and real facts about your business also matter for AI assistants that read your pages and cite them. We go deeper on that in how to get your business recommended by ChatGPT and in our guide to AI crawlers and robots.txt. A redesign that blocks those crawlers by accident in robots.txt costs you visibility in a place many owners never check.
Launch day: the checklist
This is the part that takes an hour and saves months. We run it on every launch.
- Remove noindex and staging blocksCheck the page source for a robots meta "noindex" tag and open /robots.txt. Staging sites often block everything, and that setting sometimes ships to production.
- Test the redirect mapRun every old URL from your spreadsheet through a crawler or a redirect checker. Each should return one 301 or 308 to the right page. No 404s, no chains.
- Check canonical tagsEvery page should point to its own new URL, not to the staging domain or the old address.
- Submit the new sitemapUpload the new sitemap.xml in Search Console. Google says warnings about redirecting URLs in the old sitemap are expected during a move.
- Inspect your top pagesUse URL Inspection in Search Console on your five to ten most valuable pages and request indexing.
- Test forms and trackingSend a real test through every contact form, and confirm analytics records the visit. A redesign that ranks but loses leads is still a failed redesign.
If you are also changing domains, for example from oldname.com to newname.com, use the Change of Address tool in Search Console as well. It is not needed for a redesign on the same domain or for HTTP to HTTPS.
After launch: what is normal and what is not
Some movement is normal. Google's documentation says it can take "a few weeks or more" for a medium-sized site to start showing the new URLs, with temporary fluctuation in between. Larger sites take longer.
| Signal in the weeks after launch | Normal or not |
|---|---|
| Small ranking dips that recover within 2-6 weeks | Normal |
| Old URLs showing as "Page with redirect" in Search Console | Normal, that is the redirect working |
| A rise in "Not found (404)" pages | Fix it: some redirects are missing |
| "Excluded by noindex tag" on new pages | Fix it now |
| Clicks down sharply on specific pages after 8 weeks | Compare old and new content for those pages |
| Clicks down across the whole site after 8 weeks | Something structural: robots, canonicals, speed or redirects |
Compare the same periods. Seasonal businesses should compare against the same weeks last year, not the month before launch.
What this costs, and where we come in
A careful redesign adds work that a cheap quote often skips: the crawl, the redirect map, content carry-over and launch checks. That is why two quotes for the "same" redesign can differ so much. We break down the market prices in how much a website redesign costs in 2026.
When we rebuild a site, the redirect map and launch checks are part of the job, not an add-on. A custom 4-6 page business website starts at 2,199 lei (about EUR 415), delivered in 14-21 days with a fixed price in writing before we start. If the design is fine and the problems are speed, technical SEO or Core Web Vitals, Web Optimization starts at 699 lei (about EUR 130) and comes with a detailed report of everything we fixed. Details are on our services page, and past work is on our projects page.
Do it yourself or hand it off?
Doing it yourself is reasonable when the site is small (under 20-30 pages), you keep the same platform and the same URLs, and organic search is not your main source of clients. In that case the launch-day checklist above covers most of the risk.
Hand it to someone when you are changing platforms or domains, when many URLs will change, or when Google brings in a real share of your leads. One missed redirect on a page that sells is expensive. A good first step either way is the free website audit. If you would rather talk it through, email [email protected] or start from our services page. We reply with a fixed price and a delivery date.
Frequently Asked Questions
Will redesigning my website hurt my SEO?
A redesign hurts SEO only when it breaks something Google relies on: URLs that change without redirects, ranking content that gets cut, slower pages or a leftover noindex tag. If you keep URLs stable or redirect them one-to-one, keep the content that ranks and check the site on launch day, you can expect a short period of fluctuation, not a lasting loss. Many redesigns end up improving rankings because the new site is faster and better structured.
How long does it take for SEO to recover after a website redesign?
For a small or medium site with correct redirects, rankings usually settle within a few weeks. Google's site move documentation says it can take a few weeks or more for a medium-sized site to start showing the new URLs, and larger sites take longer. If traffic is still clearly down after about two months, look for missing redirects, removed content or indexing problems in Search Console instead of waiting longer.
Do I need 301 redirects if I redesign my website?
You need permanent redirects for every URL that changes. If a page keeps exactly the same address on the new site, it needs no redirect. Google recommends server-side permanent redirects (301 or 308), each pointing to the most relevant new page, and keeping them for at least one year. Redirecting everything to the home page is a common mistake that Google can treat as a soft 404.
Should I change my URL structure during a redesign?
Only if the current structure is causing real problems, such as messy query strings, duplicate paths or URLs that no longer describe the page. Every URL change adds risk and needs a redirect, so changing URLs only for neatness is usually not worth it. If you are moving platforms and the new one forces a different structure, plan the full redirect map before launch.
What should I check right after launching a redesigned website?
Confirm there is no noindex tag or robots.txt block left from staging, test every old URL in your redirect map, check that canonical tags point to the new URLs, submit the new sitemap in Search Console and use URL Inspection on your most important pages. Then send a test through every contact form and confirm analytics is recording visits.
Can a website redesign affect how AI assistants like ChatGPT see my business?
Yes. AI assistants and AI search tools read your pages the same way crawlers do, so broken URLs, removed facts or a robots.txt that blocks their crawlers can make your business harder to find and cite. Keep clear headings, direct answers, accurate business details and structured data on the new site, and check robots.txt after launch.
How much does it cost to redesign a website without losing SEO?
The cost depends on the size of the site and on whether you change platforms. The SEO part adds work: crawling the old site, building a redirect map, carrying over content and checking the launch. At Legacies, a custom 4-6 page business website starts at 2,199 lei, about EUR 415, with that work included and a fixed price agreed before we start. Market ranges for redesigns are covered in our separate redesign cost guide.
