Case Study: Ruukki achieves 700% faster site speed and increased leads with Progress Sitefinity

Ruukki Site Speed Soars 700% with Progress Sitefinity and ASP.NET MVC

Ruukki Construction, part of SSAB and a Nordic supplier of steel-based roofing and wall products across 10 European countries, faced a deteriorating digital experience: Google PageSpeed scores fell from the 70–80 range to around 10, harming SEO, customer experience and web-driven leads. The site relied on older ASP.NET Web Forms technology and also needed updates for a rebrand, GDPR tracking and accessibility—creating a clear business case to modernize performance before making other content or design changes.

Ruukki kept Sitefinity as its CMS and migrated 30 sites from Web Forms to ASP.NET MVC, preserving integrations and content while streamlining templates and delivery. The three-month transition lifted PageSpeed to 80 (a ~700% improvement), drove a 30% increase in page views, a 50% jump in B2B leads and notable gains across metrics (70% more content requests, 6% lower bounce, 36% more B2C visitors, 20% more B2C page views, and 16% more goals met).
