Planning a Website Redesign Without Losing Content or Search Visibility

When a redesigned website loses search visibility, the new design is rarely the reason. The usual causes are mundane: old page addresses (URLs) stop working, pages that brought in visitors are dropped, or the new site is still blocked from search engines after launch.

You can reduce that risk considerably, but you cannot remove it. Before launch, list every old URL, decide where each one should lead, and set up permanent redirects (301 or 308). After launch, check that they work. Google itself says rankings may fluctuate during a move and settle down over time.

For a small business site with 10 to 30 pages, this is an afternoon's work with a spreadsheet, not an agency project.

Why a redesign can cost you visibility

Search engines know your site by its addresses. If your services page used to live at /services.php and now lives at /services, Google treats it as a new page at first. The old address returns an error (404), and links from other websites, directories and old emails stop working.

Google says that an indexed URL which returns a 404 is removed from its index. A redirect, on the other hand, tells browsers and search engines where the content has gone. Google treats a permanent redirect as a strong signal that the target is now the main (canonical) address.

Three other problems come up again and again:

• Pages that used to bring in enquiries are cut or heavily shortened.
• Page titles and descriptions are lost because nobody copied them from the old system.
• The new site was hidden from search engines while it was being built, and the block is still there after launch.

Step 1: take stock of the old site

Before anything changes, you need a complete list of your current URLs. Good places to find them:

• the old XML sitemap (often at /sitemap.xml),
• the page list in your current CMS (content management system, the tool you use to edit pages),
• the Performance report in Google Search Console, which shows which pages people reach from Google Search,
• your analytics tool, if you use one,
• linked PDF files such as price lists or brochures, which have their own URLs too.

Add a short note to each URL: what is on it, and whether it clearly brings visitors. Pages that people find through search deserve extra care.

Step 2: decide what happens to each URL

Every old address gets one of three decisions:

1. Keep: the content and the URL stay the same. This is the safest option. If your current URLs are clean and readable, there is no need to change them.
2. Move or merge: the content gets a new address, or several old pages become one new page. Redirect each old URL to the new page that covers the same topic.
3. Remove: there is no sensible successor, for example a service you no longer offer. The old URL can return a 404 or 410. Redirecting it somewhere unrelated helps nobody.

Google explicitly advises against redirecting many old URLs to one irrelevant destination such as the home page. It confuses visitors and may be treated as a "soft 404", in other words like an error page. Merging is fine when the old content really is on the new page.

301 or 308? Redirects in plain words

A redirect is an instruction from the server: "This address has moved, the content is now here." Browsers and search engines follow it automatically. The number is the HTTP status code.

Google recommends server-side permanent redirects for permanent moves, and shows the new target URL in search results. JavaScript redirects should only be used if server-side options are not possible.

Which exact code your developer uses is a technical detail. What matters to you: permanent, server-side, straight to the final page.

The redirect map: template and example

A redirect map is a simple table: old URL, new URL, status. It is the work order for whoever sets up the redirects and your checklist after launch.

Pre-launch checklist

Go through this with your developer shortly before go-live:

• The list of old URLs is complete, including linked PDFs.
• Every old URL has a decision: keep, redirect or remove.
• The important content from old pages exists on the new site, not just the headings.
• Each page has its own clear page title and description. Good old titles were kept or deliberately improved.
• Internal links on the new site point directly to new URLs, not to old ones that redirect.
• The staging block is gone: no "noindex" (an instruction not to include a page in search results) and no robots.txt rule meant only for the build phase.
• An XML sitemap of the new URLs is ready.
• Redirects are live on the server and spot-checked.
• Impressum (the legal notice German law requires), privacy policy and contact form work on the new site.
• Load time of the key pages on a phone has been checked, for example with PageSpeed Insights.

On speed: Google publishes Core Web Vitals thresholds (main content loaded within 2.5 seconds, response to input under 200 milliseconds, little layout shift). Meeting them aligns with what Google's ranking systems reward, but it is not a guarantee of positions.

After launch: the first weeks

Expect some movement. Google notes that for a medium-sized site it can take a few weeks or more before the new URLs replace the old ones in results. Don't judge the redesign on the first few days.

If the redesign adds a second language

Many businesses in Germany use a redesign to add German next to English, or the other way round. URLs then often change twice, for instance when all existing pages move under /en/. The redirects work exactly as described above. How to connect the language versions (hreflang) and what to translate is covered in our guide to a bilingual German and English website.

Who does what

You can do the inventory yourself, because you know your content best. Setting up and testing redirects is a job for your developer. Before you sign, ask whether implementing the redirect map is part of the quote, and who watches for 404 errors after launch. The latter is a typical question for website maintenance. For the overall sequence of a project, see how a website project runs.

At Ichii, your current website is one of the materials you send us at the start. A new business website with up to 10 pages costs €790 net (plus VAT), one-time, built on a proven design system with your final text and images. More than 10 pages, extra languages and larger changes are quoted separately.

Your next step

Copy the template above into a spreadsheet and fill in the URLs of your current site. With that list, any developer can judge the effort and scope of your redesign realistically. If your new site will have up to 10 pages, you'll find what's included and the price on our business website page.
