The short answer
Your website needs a relaunch when several of these seven signals apply at once: a weak mobile experience, slow load time, a design that no longer fits the brand, no clear next step, maintenance only through third parties, forms that feel bolted on, and a competitor who suddenly looks more modern.
If one signal applies, a targeted fix is usually enough. From four signals on, a complete relaunch is almost always cheaper than many individual repairs in our project experience. With the table further down you can check your site yourself in 30 minutes.
"The site somehow feels old" is the sentence clients most often come to us with. It's almost never the actual finding. Behind it there's usually a combination of several of the following signals. We go through each one and tell you how to spot it concretely.
1. Does your site really work on a phone?
Around 60 % of page views in Germany now come from smartphones [1]. Depending on the industry it's considerably more. Yet we regularly see sites that "work" on mobile but feel like a shrunken desktop version. Typical: tiny tap targets, forms that don't fit on the screen and a menu you have to hunt for.
That's not only a question of looks. Google uses the mobile version of your content for indexing and ranking [3]. What's missing or hard to reach on mobile barely counts for Google. How to check: take your own phone, not the browser simulator. Open the site via Google and try to send an enquiry in under a minute.
2. How fast does your site load?
Load time feeds into Google's assessment of page experience via the Core Web Vitals. Google names three target values [2]: the largest visible element (LCP) should appear within 2.5 seconds. The response to an input (INP) should be under 200 milliseconds. And the layout should hardly shift while loading (CLS under 0.1).
More important still: visitors notice every second. Typical causes on older sites are uncompressed images, too many external scripts such as chat widgets or old plugins, and hosting that no longer fits. How to check: enter your homepage in Google PageSpeed Insights. Look at the field data from real users first, not just the score.
3. Does the site still fit your company?
Companies evolve: new services, new target groups, a sharper profile. The website often stays put, because nobody puts "change the website" on the agenda. Then it describes a company that no longer exists in that form.
That's a question of trust, not of taste. Anyone who hears something different in a conversation from what they read online becomes cautious. How to check: put your three most important services of today next to your homepage. Do they appear there in that order and in those words?
4. Does a visitor know what to do next?
Visitors read, nod inwardly and leave again, because nowhere does it become clear what the next step is. A good call to action isn't "Contact" in the menu. It's a clear offer such as "Book a 30-minute call" or "Request a free audit" that comes back at every suitable point.
How to check: show the homepage for five seconds to someone who doesn't know your company. Then ask: what do we offer, and what would you click now? If they hesitate, the clear next step is missing.
5. Can you maintain the site yourself?
If every text correction, every new reference and every price change needs an external request, content goes stale. The hurdle is simply too high. A relaunch is the right moment for a CMS that matches the real maintenance effort – neither oversized nor too simple.
Then there's the technology under the hood. Many older sites run on a PHP version that no longer gets security updates. According to php.net, in October 2026 only versions 8.2 to 8.5 still receive security updates, 8.2 only until 31 December 2026 [4]. How to check: look up the PHP version in your hosting panel and open updates in the CMS. If it says 8.1 or older, that's a clear signal.
6. Do form and booking feel like foreign bodies?
You can often tell that functions were added later: a different style, a different load time, a different mobile display. That weakens trust exactly where it matters most – just before someone gets in touch.
One example from our work is Hotel Zuckerfabrik in Stuttgart. On the old site, checking availability only worked via a detour to an external booking platform. The hero had no incentive to book. After the relaunch, headline, "Book now" and an availability widget sit directly in the hero, and the rooms are shown as photo cards.
7. Does your competitor suddenly look better?
This is often the real trigger for a relaunch enquiry. A competitor goes live with a new site, and suddenly the difference is visible. Nothing has changed on your own site, but the yardstick has shifted. Prospects often compare two or three providers directly one after the other.
How to check: open your site and those of two competitors side by side on a phone. At first glance, does your site look more modern, on a par or noticeably older?
How do you do a mini-audit in 30 minutes?
Before you commission a project, an honest inventory pays off. The table summarises the seven signals. Tick each row if the right-hand column applies to your site.
| Signal & tool | Applies if … |
|---|---|
| Mobile Your own smartphone | you can't send an enquiry in under a minute |
| Load time PageSpeed Insights | LCP is above 2.5 s or INP above 200 ms |
| Brand Your list of services | the homepage shows different priorities from today's |
| Call to action 5-second test | a stranger can't say what they'd click |
| Maintenance & tech CMS, hosting panel | you can't change texts yourself or PHP 8.1 or older is running |
| Forms Your own test enquiry | form or booking look different or jump to another site |
| Competition Two competitor sites | your site looks noticeably older |
Two further checks are worth it. Trace back your last three contact enquiries: did they come because of the site or despite it? And look in Google Search Console: have clicks and impressions for your most important search terms been falling for months?
Is a fix enough or do you need a full relaunch?
Count your ticks from the table. As a rule of thumb from our project experience:
- 1 signal applies → a targeted fix is usually enough, for example only optimising load time or only sharpening the CTA.
- 2–3 signals apply → first a structured audit. It shows whether the problems are connected or isolated.
- 4 or more signals apply → at this point a complete relaunch almost always pays off more than the sum of the individual fixes.
Example (typical case, fictional): a trades business with twelve employees has a site from 2018. It loads in just over four seconds on mobile, runs on PHP 7.4, the contact form is an old plugin, and the new heat pump division is missing completely. That's four ticks: load time, maintenance & tech, form and brand. Every individual repair touches the same outdated base. Here a rebuild is more honest than four patches.
What a relaunch realistically costs in the Stuttgart region is in the article on the price range 2026. For an SME project with 5–12 pages and no shop we plan 4 weeks from the completed briefing.
When is a relaunch the wrong answer?
Not every problem is a website problem. If your site is technically solid but hardly anyone finds it, a new design won't help much. Then the lever is visibility.
Our project with Batteriecenter Ludwigsburg shows this. The online shop stayed. We aligned content with search terms, set up a product feed in Google Merchant Center and built tracking. From April to August 2026 visitors rose by 521 % and average revenue by 162 %. A relaunch wouldn't have closed these gaps.
The reverse also holds: if visitors come but don't enquire, the problem is usually on the site itself. Then signals 4 and 6 are the first candidates. How to build the path from visit to enquiry is in the article on conversion funnels.
