Have you launched your new corporate website only to see your organic traffic disappear overnight?
You invest thousands of euros in a spectacular redesign. Your development team works for months on a hidden subdomain so everything is perfect. But after the migration, your potential clients can no longer find you. What nobody told you is that Googlebot discovered that unprotected test environment, indexed it before launch, and now your main domain is suffering an algorithmic penalty for massive duplicate content. You are competing against your own toxic clone, and it is winning the battle for transactional keywords.
The trap of migrating on unisolated subdomains
Most agencies and developers blindly trust a simple robots.txt file or a noindex tag to block Google, ignoring that internal links or third-party integrations can force crawling. When the staging environment moves to production without a signal consolidation strategy, the search engine gets confused, dilutes your domain authority, and blocks the visibility of your service pages. An exposed development environment is not a design flaw, it is a lethal hemorrhage for your B2B conversions.
Our solution: Technical SEO Isolation and Migration Audit
At LANZA ESTUDIO we do not cross our fingers hoping Google understands the change. We reverse-engineer your server architecture and execute an emergency de-indexing protocol to annihilate the staging subdomain's trail, transferring all retained authority to your production domain.
- Server-level perimeter blocking: We implement HTTP Basic authentication and strict firewall rules to ensure no bot can access the clone.
- Signal mapping and consolidation: Deep crawls to identify every indexed subdomain URL and apply strategic 301 redirects to production.
- Google index purging: Advanced use of the Indexing API and bulk removal tools to clean the SERPs of toxic results in record time.
- Analytics and API reconfiguration: Sanitization of your Search Console properties and conversion funnels so business data becomes 100% reliable again.
The Real Impact on your B2B Sales
- Recovery of transactional traffic: Your main domain regains exclusive ownership of the content, climbing rapidly to the first page of Google.
- End of organic cannibalization: Your potential clients land on service pages ready to convert, not on broken development versions.
- Crawl budget acceleration: Googlebot stops wasting time on useless copies and focuses on indexing your new success cases and profitable products.
