Scalable Webflow portfolio for real estate agents
Assignment
Aurentum Immobilien was already using Webflow, but lacked a consistent naming system. The result: cluttered HTML and CSS that was being overridden individually for every breakpoint. Furthermore, it lacked proper SEO settings and structured data (schema markup) for visibility in AI-generated answers (GEO).
Challenge
No consistent naming system, CSS overrides per breakpoint instead of a centralized system, and poor scalability. Additionally, poor SEO settings and no schema markup for GEO.
Solution
The entire website has been technically rebuilt using the Lumos framework, which provides a central, consistent class system instead of the previous breakpoint overrides. Every element now follows a clear naming convention, the HTML is semantically structured (replacing generic divs), and styles are managed via responsive variables rather than hundreds of individual CSS overrides. This significantly reduces the CSS footprint and allows for future adjustments to be implemented quickly without unintended side effects.
In parallel, the entire SEO foundation was overhauled: title tags, meta descriptions, and URL structures were cleaned up, duplicate heading levels were corrected, and internal linking was improved. For AI visibility (GEO), a comprehensive schema markup was implemented, featuring a central organization entity (LocalBusiness + RealEstateAgent) referenced via @id on all subpages, as well as WebPage/Service schema for regional landing pages (e.g., real estate agents by town).
The CMS structure was also designed for scalability, including bulk SEO titles for over 340 properties, field migrations (PlainText to RichText for greater formatting flexibility), cleanly linked status and district references, and a dedicated town collection for regional pages.
Google Page Speed Scores
The results are measurable: the on-page SEO score is 85/100 ("Great"), Core Web Vitals are fully passed (LCP 1.1s, CLS 0.01), and PageSpeed scores reach 96 (Performance), 100 (Accessibility), 96 (Best Practices), and 100 (SEO) on desktop. The impact of the GEO optimization is most evident in AI citations, which have shown a clear upward trend since the transition—a direct result of the clean schema foundation.
