Relaunch of the Agency Website for K&K Ferienimmobilien (WordPress MultiSite)

We have been supporting K&K Ferienimmobilien as a digital partner for over 10 years. In that time, not only has the website landscape grown, but also our understanding of what property owners really need and how to communicate it convincingly online. For our long-standing client, we were entrusted with relaunching the new agency website as a clear counterpart to the already existing location-based destination sites in the WordPress MultiSite. The special feature: its own design & its own theme, but still centrally managed in the same MultiSite backend. On top of that: custom-developed icons and a setup that cleanly combines performance, accessibility, and SEO.

Starting point & challenge

K&K operates multiple destination websites (location-based presences) in a WordPress MultiSite system alongside the main portal kuk-ferienwohnungen.de. The new agency website, unlike these sites, targets not vacationers but owners of holiday apartments and holiday homes. Therefore, the new agency website needed to:

• be clearly recognizable as the main brand (maintaining its own look & feel for the target group of property owners),
• run within the same MultiSite network (central administration, same infrastructure),
• perform at a high level technically & from an SEO perspective (Core Web Vitals, on-page quality, structured data),
• and simultaneously be implemented accessibly / ‘compliant’ according to WCAG/BFSG.

Our solution: custom theme in MultiSite — centrally manageable, visually independent

We implemented the agency website so that it has its own theme (design, typography, component logic), but without being an isolated solution: updates, system maintenance, and network management remain centrally controllable in the MultiSite backend.

Additionally implemented:

• Custom icon set created (for services/USPs/modules — consistent with the brand identity)
• Clean content structure for conversion & orientation (services, proof, plus points, guide, podcast, partners, contact)

Content with a conversion focus (homepage as a ‘sales page’)

The structure of the homepage was clearly oriented towards the owner target group and value-based argumentation:

• Hero: ‘We make your holiday apartment more profitable’ (direct benefit rather than self-description)
• Service blocks: marketing, booking management, guest support, cleaning, linen service, property management
• Trust elements: portal logos/distribution, key figures, reviews
• Lead magnet: PDF guide
• Content branding: podcast teaser + QR code reference
• Regional strength: partners & locations visibly integrated

Technical excellence, quality & measurable results

At launch, the quality metrics were where they belong — at the top:

• Security Headers: A+
• Accessibility: compliant
• PageSpeed (mobile): 92
• Seobility OnPage Score: 92

Especially the combination of MultiSite setup and custom theme alongside strong KPIs shows: scaling doesn’t have to mean compromise.

PageSpeed: fast website for users & Google

A strong website must feel fast — especially on mobile. That’s why we implemented the new K&K website so it loads performantly and remains stable even on smartphones. Result: PageSpeed (mobile) 92 — for a better user experience, fewer bounces, and a solid foundation for SEO. As an agency specializing in PageSpeed optimization, we are practically obsessed with not going live with any project that doesn’t achieve at least 90 in PageSpeed Insights for mobile.

Accessibility: compliance instead of gut feeling

Accessibility is not a “nice-to-have” — it’s a quality and future standard. We made the website accessible so it meets relevant requirements. Result: compliance with WCAG/BFSG, so content is accessible to everyone and the project is on the safe side from a regulatory perspective too.

OnPage Score: clean structure, strong SEO foundation

Good rankings don’t come from individual tricks, but from clean on-page fundamentals: clear information architecture, sensible heading structure, internal linking, metadata, and technically clean pages. Result: Seobility OnPage Score 92 — as a solid SEO foundation right from launch.

Structured data: purposeful, pragmatic, expandable

For the agency website, we integrated targeted schema markup that matches user intent:

• TravelAgency / Organization for clear entity & business context
• FAQPage to support snippets, understanding & conversion (reducing barriers, building trust faster)

Security Headers: A+ as a technical quality indicator

Security is part of brand trust and a sign of professional implementation. We hardened the website with modern security headers and best practices so that common security checks pass cleanly. Result: Security Header Rating A+ — a clear technical proof of a robust setup.

Conclusion on the WordPress relaunch of the holiday rental agency

With the relaunch, K&K Ferienimmobilien now has an agency website as a central brand stage that visually stands apart from the destination sites while remaining fully integrated in the WordPress MultiSite system. Result: strong performance, clean on-page quality, accessible implementation, and a homepage that consistently guides property owners towards contact.
