Cases
Measured results, not promises.
One project. Measured numbers.
Netvoima is a young company. Right now we have one case study. We think one honest result beats ten polished promises.
All measurements were run with Google PageSpeed Insights in the same test setup before and after. The numbers don't show traffic or revenue, they show technical health. What technical health means for your business is covered on the homepage.

Construction and renovation · February 2026
Starting point
The old site worked, but the design was dated and the mobile experience was weak. Search visibility suffered, and the site didn't reflect the quality of the work the company actually does.
What we did
- 3 design concepts, client chose the direction
- Built with modern technology, no WordPress plugins, no database
- Metadata and structured data for search engines and AI-powered discovery
- Mobile experience and conversion optimisation
- DNS migration and deployment to EU hosting (Helsinki)
- Helped with email migration to a new provider
- Ongoing monitoring after launch
Results: Google PageSpeed Insights, mobile
Tested 26 Feb 2026, Slow 4G, Moto G Power
- Performance: 43 → 92
- SEO: 91 → 100
- FCP (First Contentful Paint): 3.0 s → 0.9 s
- LCP (Largest Contentful Paint): 18.4 s → 3.3 s LCP improved significantly, but it's still toward the upper end of the good range. Ongoing monitoring makes sense.
- Speed Index: 4.5 s → 1.1 s
- CLS (Cumulative Layout Shift): 0.882 → 0
- TBT (Total Blocking Time): 0 ms → 20 ms TBT increased slightly, but both measurements are in the excellent range (under 200 ms).
“The new site turned out great.”

Case studies build up as projects finish and clients give permission to publish. If you're making a decision based on a single reference, say so directly, that's completely understandable. We can talk through your project with no strings attached.
