The verdict in three sentences
Rebuilding an industrial catalog site with a product configurator and reseller area costs between 22,000 and 55,000 EUR (excl. VAT) in 2026, depending on catalog depth and configurator complexity. Budget 12 to 16 weeks, a rigorous SEO migration (301 redirects) and maintenance of 300 to 500 EUR/month. The number one risk of an industrial rebuild is not the design: it is losing SEO traffic if the migration is botched.
Cost lines of an industrial rebuild
An industrial site has a dual constraint: a large technical catalog (references, spec sheets, downloadable documentation) and a quote-request funnel. The product configurator and reseller area are the heaviest lines. SEO migration is the most critical: 8 years of ranking can vanish in weeks if 301 redirects are done poorly.
| Line item | 2026 range (EUR excl. VAT) | Stake |
|---|---|---|
| UX + catalog design | 4,000 - 9,000 | technical clarity |
| Product configurator | 6,000 - 16,000 | conversion core |
| Reseller area | 4,000 - 10,000 | secure access, pricing |
| SEO migration (301) | 2,500 - 6,000 | preserve traffic |
| Spec sheets + docs | 2,000 - 5,000 | tracked downloads |
| QA + launch | 2,000 - 4,000 | cross-browser |
Measurable goals after rebuild
A manufacturer does not rebuild to look pretty but to generate more qualified quote requests at controlled cost. Here are the target metrics observed on comparable projects.
| Metric | Before rebuild | Target at 9 months |
|---|---|---|
| Monthly organic traffic | baseline | +50% |
| Quote requests / month | 15 | 25-30 |
| Cost per request (Ads) | 45 EUR | 28-32 EUR |
| Mobile bounce rate | 62% | < 45% |
| Pages per session | 2.3 | 3.5+ |
| Mobile LCP | 4.1 s | < 2.3 s |

Marc, sales director of a mechanical components manufacturer in Strasbourg. His old site generated 15 quote requests per month, at a cost per request of around 45 EUR via Google Ads. He invests 38,000 EUR (excl. VAT) in a rebuild with a product configurator and a careful SEO migration. Nine months later, organic traffic grows 50% and requests reach 27 per month, an increasing share from organic (thus with no acquisition cost). Average cost per request drops to 30 EUR. On an average order of 4,200 EUR and an 18% conversion rate, the 12 extra monthly requests represent about 2 more orders per month, i.e. a return on investment in under 8 months.
FAQ
Why is SEO migration so critical? An 8-year-old site has built a capital of rankings and backlinks. Without an exhaustive 301 redirect plan, you can lose 30-60% of organic traffic within weeks, with direct commercial impact.
Is a product configurator really worth it? Yes for a technical catalog: it qualifies demand upstream, reduces sales back-and-forth and raises conversion. It is often the line that pays back the rebuild fastest.
How long to recover the previous traffic level? With a clean migration, traffic usually stabilizes within 4-8 weeks, then grows further thanks to technical and content improvements.
Does the reseller area complicate maintenance? It adds an authentication and pricing-management layer, so slightly higher maintenance (around 400-500 EUR/month). In return, it retains the network and automates sales tasks.
Can we rebuild in phases? Yes: deliver the catalog + SEO base first, then the configurator, then the reseller area. This smooths cash flow and secures the migration.
