Website Relaunch 2026: Cost, Process and SEO Risks

A website that has not changed in years rarely costs you loudly - it costs you quietly, through inquiries that stop arriving because the site struggles on a phone or simply looks dated. A relaunch is not a cosmetic decision, it is an economic one, provided the technical side is handled cleanly. Here are the realistic costs, the biggest risks in SEO migration, and a process that actually works.

When a relaunch is genuinely worth it

Not every website needs a relaunch just because it has a few years on it. Several signals, though, point to an existing site costing more than it delivers:

• The site is older than four years and has not been substantially reworked since
• It performs poorly on mobile, even though most visitors arrive on a phone
• Inquiries through the website have been noticeably declining for several months
• Bounce rate is consistently very high, visitors leave almost immediately
• Load times are uncomfortably slow, especially on mobile connections
• You hesitate to link to the site yourself in a newsletter or referral

If two or more of these apply, a relaunch is usually the more economical choice than continuing to patch a site that is dated at its core. With four or more signals at once, the site is already actively losing ground to competitors who present themselves more modernly. For an architecture or engineering firm, this often shows up most clearly in the portfolio, which forms the central proof of trust there - more on that in Websites for Architects and Engineers.

What a relaunch costs in 2026

The price range for a relaunch is wider than for a brand-new site, because migration and continuity have to be planned alongside the redesign itself:

These figures are a market range, not one specific provider's price list. What every serious quote should include, regardless of scope: a planned SEO migration, an updated schema.org setup, a load-time check after go-live, and clean mapping from every old URL to its new counterpart. Skip any of these, and you pay for it later through lost visibility, even if the initial price looked attractive.

As an alternative to a one-off project fee, we also offer relaunches as part of our monthly model: 349 € net per month with a 12-month minimum term, then 49 € net per month for hosting and maintenance. Details are on our pricing page.

The SEO migration: the biggest risks

A relaunch that looks great but is migrated carelessly can do more damage than the old site ever caused. Three mistakes are especially common. First, the URL structure changes without clean 301 redirects from old to new - Google loses the connection, and rankings for the affected pages drop. Second, existing schema.org data such as Organization or LocalBusiness markup quietly disappears in the new build because nobody thought to carry it over. Third, the new site looks better but loads slower than the old one - a regression in load time directly affects both rankings and bounce rate.

The clean alternative: every existing URL gets mapped to a new one before launch, all structured data gets checked and carried over, and the new site's performance gets measured against the old one before it goes live. Ask any quote directly how this migration step actually works - a vague answer is usually a warning sign.

The process behind a clean relaunch

A relaunch that avoids major surprises follows a clear order rather than a design sprint. It starts with an audit of the existing site: which URLs drive traffic, which search terms already work, which external sites link where. Next comes the concept phase, where the sitemap, structure and URL mapping get settled before any design work begins. Only then does the actual build start: design, content migration and the technical setup including schema.org run in parallel. Before launch, the 301 mapping gets tested end to end, then the site goes live along with a fresh submission to Google Search Console. In the following weeks, the new site gets watched closely so deviations surface early instead of months later. We cover how to steer a project like this actively as the client, rather than just waiting for updates, in Having a Website Built.

Before the relaunch: the checklist

Before the actual work begins, a short stocktake pays off - it prevents valuable data from being lost that cannot be reconstructed afterwards:

• Exported analytics and Search Console data from the last twelve months
• Documented your top pages by visitor numbers
• Captured known backlinks, meaning which external sites link to which of your URLs
• Mapped out current inquiry paths on the website
• Gathered all content - text, images, video - in full
• Written down a clear goal for the relaunch, such as more inquiries or a more modern look

Concrete steps for the next 90 days

• Days 1-30: audit the existing site, document top pages and backlinks, gather at least three quotes
• Days 31-60: settle the concept, URL mapping and schema.org structure, prepare content for the new site
• Days 61-90: test the relaunch technically, verify the 301 mapping, go live and watch the first weeks closely

Conclusion

The price in 2026 sits roughly between 800 € and 10,000 € depending on scope, with 1,500 to 3,500 € typical for a small business site. The line item that decides the outcome, though, is missing from a lot of quotes: the redirect map from old URLs to new ones. Without it, you lose rankings on moving day that took years to build - and the handsome new site costs you inquiries at first instead of bringing them in.
