The verdict in three sentences
A B2B manufacturing website redesign in Berlin budgeted at 24,000 EUR in 2026 generated +45% quote requests in 6 months and divided the cost per lead by 2.3. Load speed dropped from 4.1s to 1.8s LCP, improving both experience and SEO. Return on investment was reached in 7 months, margin on new contracts included.
Before / after: the redesign KPIs
The client, an industrial equipment manufacturer with 12M EUR turnover, started from an 8-year-old site that was slow and non-responsive. Here are the metrics measured before and 6 months after the redesign.
| KPI | Before | After (6 months) | Change |
|---|---|---|---|
| Quote requests / month | 31 | 45 | +45% |
| LCP (load speed) | 4.1s | 1.8s | -56% |
| Visitor → lead conversion rate | 1.4% | 2.6% | +86% |
| Cost per lead (with ads) | 62 EUR | 27 EUR | -2.3x |
| Page views / session | 2.3 | 3.9 | +70% |
| Average rank on target keywords | 14 | 6 | +8 places |
| Bounce rate | 68% | 41% | -27 pts |
The combination of speed + UX redesign + technical SEO produced a compounding effect: more qualified traffic, better converted, at reduced ad cost.
The detailed budget and ROI calculation
A redesign is only a rational investment if the ROI is quantified. Here is the budget breakdown and the return calculation.
| Item | 2026 budget (EUR) |
|---|---|
| UX/UI design + mockups | 6,500 |
| Development + integration | 10,000 |
| Content migration + technical SEO | 3,500 |
| Performance optimisation (LCP) | 2,000 |
| Copywriting + EN/DE translation | 2,000 |
| Total redesign | 24,000 |
With 14 extra quote requests per month, an 18% conversion rate and an average margin of 2,200 EUR per contract, the monthly gain is around 5,544 EUR (14 × 0.18 × 2,200). The 24,000 EUR budget is thus recouped in ≈ 4.3 months on additional margin alone; factoring in the real signing delay of industrial contracts, ROI is reached in 7 months.
Mini case study
Thomas, sales director at the Berlin manufacturer, doubted the value of investing 24,000 EUR in a website. Six months on, he counts 14 extra quote requests per month. With an 18% conversion rate and a 2,200 EUR margin per deal, that is ≈ 5,500 EUR in additional net monthly margin, or 66,000 EUR over a year. Return on investment exceeds 175% in the first year alone, before brand value and durable SEO gains.

FAQ
How much does a B2B manufacturing site redesign cost in 2026?
Between 18,000 and 35,000 EUR for an industrial brochure site with product catalogue, simple configurator and bilingual support. The case shown sits at 24,000 EUR, right in the average.
How fast do you see an impact on leads?
First SEO and conversion effects appear in 2 to 3 months, ramping up over 6 months. The Berlin case reached +45% requests at 6 months.
Why does load speed matter so much?
Going from 4.1s to 1.8s LCP reduces bounce rate and improves Google ranking. Every second gained lifts the conversion rate, here from 1.4% to 2.6%.
How is the cost per lead divided by 2.3 calculated?
At a constant ad budget, a better conversion rate and stronger organic SEO generate more leads: cost per lead fell from 62 to 27 EUR.
Is a 7-month ROI realistic for every manufacturer?
It depends on margin per contract and existing traffic volume. A manufacturer with high margins and decent traffic recoups faster; a niche player might target 10-14 months.
