The Brief<\/h2>

Fidelis Revision & Steuerberatung’s existing website was based on a custom-built CMS on top of CodeIgniter; additional corporate websites ran in parallel on other technical solutions. 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.<\/p>\n<\/div> <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n<\/section>

Five websites in one backend: WordPress MultiSite for a tax consultancy group<\/p>

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.<\/p>

PageSpeed 97, structured data for tax advisors, and a clear content structure<\/p>

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.<\/p><\/div>\n <\/div>\n
