Content updates, maintenance, and accessibility could only be handled with considerable effort. After a comprehensive audit of all existing websites, we jointly decided on a full relaunch on a WordPress MultiSite foundation. Today, the main website fidelis-revision.de along with four additional corporate websites runs in a single central backend. ### Five websites in one backend: WordPress MultiSite for a tax consultancy group The WordPress MultiSite system brings five corporate websites together in a single central backend. Two of the connected websites deliberately use a different color scheme but remain technically part of the same system. Content, user rights, updates, and security mechanisms are managed centrally, while each website retains its own identity in appearance and positioning. Accessibility wasn’t a later add-on but an integral part of the relaunch: structured content, clean heading hierarchies, sufficient color contrast, meaningful focus handling, and fully accessible navigation elements were implemented directly in the theme and the content modules. For Fidelis, operating as a heavily regulated audit and tax consultancy firm, data protection, accessibility, performance, and reliability are not optional extras but essential prerequisites. ### PageSpeed 97, structured data for tax advisors, and a clear content structure The new site achieves a mobile PageSpeed score of 97, excellent Core Web Vitals, and a high on-page score in Seobility. We deliberately focused on clean code, optimized image delivery, and a clear separation of content and functionality. For Fidelis, structured data per Schema.org was implemented – specifically fitted to tax advisory and audit firms – to improve findability in search results and AI-driven systems. The homepage guides visitors clearly through services, team, locations, and contacts. Content is easy to scan, clearly worded, and consistently aligned with the needs of clients. ### At a glance - Relaunch from CodeIgniter CMS to WordPress MultiSite - Five corporate websites in a single central backend - Accessibility as an integral part of the project - Mobile PageSpeed score of 97 - Excellent Core Web Vitals - High on-page score in Seobility - Structured data per Schema.org for tax advisors - Central management of content, permissions, and updates - Individual color scheme per website on a shared technical foundation ![Tablet-Ansicht und vollständiger Seitenaufbau der Fidelis-Revision-Startseite – Hero-Bereich, Team, Leistungen, Ansprechpartner, Standorte und Mandantenreferenzen](https://4eck-media.de/en/https://4eck-media.de/wp-content/uploads/2026/04/fidelis-revision-startseite-fullpage-seitenstruktur.avif "Fidelis Revision – Kompletter Seitenaufbau der Startseite") ![Mobile Standortübersicht der Fidelis Revision mit interaktiver Karte von Mecklenburg-Vorpommern – Standorte in Waren Müritz, Neubrandenburg, Demmin, Stralsund, Schwerin und Malchow](https://4eck-media.de/en/https://4eck-media.de/wp-content/uploads/2026/04/fidelis-revision-standorte-mecklenburg-vorpommern-mobil.avif "Fidelis Revision – Sechs Standorte in Mecklenburg-Vorpommern") ![Mobile Ansicht der Fidelis-Website mit Google PageSpeed Insights Score von 97 – Performance, Accessibility 96, Best Practices und SEO jeweils 100](https://4eck-media.de/en/https://4eck-media.de/wp-content/uploads/2026/04/fidelis-revision-pagespeed-97-mobile-performance.avif "Fidelis Revision – PageSpeed Score 97 auf Mobilgeräten") ![Barrierefreiheits-Scan der Fidelis-Website mit 100 Prozent Compliance-Score – 0 aktive Issues bei 21 geprüften Seiten nach WCAG-Kriterien](https://4eck-media.de/en/https://4eck-media.de/wp-content/uploads/2026/04/fidelis-revision-barrierefreiheit-wcag-compliant.avif "Fidelis Revision – 100 % WCAG-Barrierefreiheit") ![WordPress-MultiSite-Netzwerkverwaltung mit fünf Websites der Fidelis-Gruppe – zentrales Backend für Fidelis Revision, AGRO Steuerberatung, AGPV, Fidelis Rechtsberatung und Fidelis Unternehmensberatung](https://4eck-media.de/en/https://4eck-media.de/wp-content/uploads/2026/04/fidelis-wordpress-multisite-backend-netzwerkverwaltung.avif "WordPress MultiSite – Zentrales Backend für die Fidelis-Gruppe") ![Danilo Schmidt](https://4eck-media.de/en/https://4eck-media.de/wp-content/uploads/2026/04/danilo.avif "Danilo Schmidt") Danilo Schmidt Fidelis Revision GmbH Over the past ten years, we have worked with a total of four agencies. Each had its strengths, but in the end, we were always left with the feeling that things were made more complicated than they needed to be. With 4eck Media, we feel for the first time that we’ve truly found the right fit. The collaboration is straightforward, technically extremely competent, and above all, honest. What they promise is backed by substance. We particularly appreciated their technical expertise, their clear understanding of our requirements as a regulated tax consulting and auditing firm, and the calm, solution-oriented nature of our collaboration. The fact that all websites operate from a single system is not only technically outstanding but finally gives us the confidence that we are properly positioned for the long term. ## Multiple websites, one system?
