SEO audit and relaunch plan for CaNa Hallenbau
A steel hall construction company, a WordPress presence that had grown across several domains over the years, duplicate content and no local SEO. Before anything gets rebuilt, I audited what was there and laid out the options for the website relaunch, working alongside an SEO agency.

Case study
Where things stood
The web presence had grown over time: several domains repeating the same content, a WordPress site that had never been reorganised, and no local search optimisation.
Search engines struggle to make sense of that. Duplicate pages compete with each other, and without local signals there is nothing to build regional visibility on.
Approach
SEO and traffic audit
An inventory across all domains: which pages exist, which get visited, and which compete with each other.
Domain structure and duplicate content
Which domain should become the main address, which content exists twice, and how to merge it.
Stack comparison
Three options side by side: Next.js with a CMS, Next.js with WordPress as a headless CMS, and a freshly set up WordPress site. Rated on eleven criteria, with effort for build and running costs over five years.
Migration risks
What can go wrong in the move and how to prevent it: a redirect map for every old URL, a clean URL scheme and secured access to analytics.
What the assessment covered
- Day-to-day editing: who changes text and images, and how much work is it?
- Load time and technical SEO
- Visibility in AI search
- Data protection under the GDPR
- Accessibility under the German Accessibility Strengthening Act (BFSG)
- Ongoing maintenance: none of the options is maintenance-free
- Typical requests after launch, and how well each option handles them
Working with the SEO agency
The work ran alongside an SEO agency. My part was the technical side: what the current site structurally prevents, which architecture best carries the agency’s recommendations, and under which conditions each option is the right one.
The project is at the concept stage. The key lesson applies to every relaunch: it starts with an inventory, not with design. Switch off old URLs without redirects and you lose visibility that took years to build.

Has your website grown past the point anyone can follow?
I review the content, domains and technology and tell you whether a relaunch is worth it, and on which stack. Plain, honest, and without an agency chain.
