Up to half of all redesigns end with a drop in search traffic — sometimes by 50–80%. The cause is almost always the same: the new website was launched without preserving its SEO assets. You can avoid this if the redesign starts not with design but with an audit, and every old page URL gets a 301 redirect. Below is a step-by-step process that keeps your rankings through a redesign — and usually improves them.
Over the years, Google builds up “trust” in your pages: their URLs are indexed, other sites link to them, and they rank for search queries. When you launch a <a href="https://design-online.cz/en/web-development/">new website</a>, it is easy to destroy all of this in one go without even noticing. The three main causes of failure:
Page URLs changed without redirects. The page used to be /services/web-design/, now it is /nase-sluzby/tvorba-webu/. To Google, the old page has simply disappeared (404) and the new one is a stranger with no history. All the accumulated weight is lost.
Deleted or shortened content. The designer went “clean and minimalist” and threw out half the text. But that very text was what ranked for search queries. No text — no rankings.
Lost meta tags and structure. The new website was built without carrying over titles, descriptions, H1–H2 headings and schema markup. Google re-evaluates the pages from scratch.
The result: a website that sat on the first page for years drops to the second or third, and recovery takes months. And traffic usually doesn’t drop immediately, but 2–4 weeks after launch — when it is already late and scary to change anything.
Before you start drawing a new design, record what already works for you. Export from Google Search Console all the pages that bring in traffic and all the queries you rank for. This is your “do not touch” list. Every such page and every key query must survive the redesign.
Build a table: every old URL → what happens to it on the new website. There are three options: the URL stays unchanged (the best option), the URL changes and gets a 301 redirect to the new one, or the page is deleted and redirected to the page closest in content. No page may be left without a decision. A 301 redirect passes the old page's accumulated weight to the new one — this is the key mechanism for keeping your rankings.
Texts that ranked are carried over to the new website — not shortened but, where possible, strengthened. A “clean minimalist design” and SEO copy do not contradict each other: text can be tucked into expandable sections, moved into separate blocks or reworked as an FAQ. The main thing is that the content stays on the page and is accessible to Google. Titles, descriptions and the heading structure are carried over at the same time.
Everything Google likes is set up on the new website: loading speed, a mobile version, a correct robots.txt (not blocking CSS/JS), a sitemap, schema markup. If the website is multilingual, correct hreflang. All of this is checked on a test address before the domain is switched.
Step 5. Launch and monitoring The new website is built on a test address while the old one keeps running without interruption. The switch takes minutes. Immediately after launch: submit the new sitemap to Google Search Console and Seznam (the Czech search engine), check that all redirects work and switch on rank monitoring. For the first 2–4 weeks, a weekly check: are 404s increasing, have key queries dropped? If something has moved, fix it quickly.

Before you switch the domain to the new website, make sure that: all old URLs return either a 200 or a single 301 redirect (no chains);
the content of ranking pages has been carried over in full;
titles and descriptions are in place;
the sitemap is ready; speed and the mobile version are no worse than on the old website;
for multilingual websites, hreflang is error-free. Skipping any of these points is a potential loss of traffic.
If traffic falls after launch, don’t panic and don’t roll everything back — diagnose first. Most often the cause is specific: a forgotten redirect, a page returning a 404, a lost piece of text. Check the “Coverage” report in Search Console for a rise in errors and compare your top pages against the list from step 1. Usually the problem is found and fixed within a day or two and rankings come back. Full recovery, if everything is done right, takes two to four weeks.
A redesign is not dangerous in itself, but because it is often done by designers with no regard for SEO. A safe redesign starts with an asset audit, rests on a 301 redirect map and preserved content, and ends with rank monitoring after launch. A redesign done this way does not knock down traffic but raises it: the new website is faster, clearer and technically cleaner, and Google rewards that. If you are not confident doing it in-house, entrust the redesign to a team that is responsible for both design and SEO.
