Website relaunch, without a ranking crash.

A relaunch is one of the riskiest projects there is: done wrong, 30–70 % of organic traffic can vanish overnight. We support relaunches with a fixed protection process, including 1:1 redirect mapping, crawl comparison and a rollback plan.

  • 1:1 redirect mapping
  • Crawl comparison
  • 8-week monitoring
  • Rollback plan
In short

A website relaunch with Loomup brings a new design without a ranking crash: URL mapping, 301 redirects and monitoring protect the visibility you've built over years right through go-live.

Shown visually

Every old URL maps cleanly to the new one

The most common relaunch mistake is missing or blanket redirects. We map 1:1 – so the visibility built over years stays intact.

Good to know

The key questions, answered briefly

What do you need to watch out for in a website relaunch?

The critical points are: complete old-to-new URL mapping, 301 redirects, preserving important content, technical crawlability and monitoring before and after launch. Ignore these and rankings collapse.

Design relaunch or a complete rebuild?

That depends on condition and goals. A pure design relaunch keeps the substance, a rebuild pays off when the tech is outdated. In both cases, protecting the SEO during the transition is decisive, and that's exactly where we come in.

Risk

Why do websites often lose rankings in a relaunch?

Because URLs change without being redirected cleanly, content is lost, or the new site is technically harder to crawl. Without SEO support, rankings often drop by 20–60 % in a relaunch, an avoidable and often costly loss.

Protection

How do you protect rankings in a website relaunch?

Through a structured approach that carries existing visibility over without loss:

Complete URL mapping old → new before go-live.
301 redirects for every changed URL.
Preserve content & meta data, or improve it deliberately.
Check crawlability: indexing, Technical SEO.
Monitoring before, during and after launch.

FAQ

Common questions

When is the best time?
