SEO Migration & Relaunch Services

SEO-safe website migrations and relaunches with zero ranking loss

Website migrations are one of the highest-risk operations in SEO. Most ranking losses are not caused by Google updates — they are caused by poorly executed relaunches. H-Studio provides engineering-grade SEO migration services for companies in Germany and the EU. We handle migrations as controlled system changes, not content updates — with full protection of rankings, visibility, and organic traffic.

Why Most SEO Migrations Fail

Typical causes of ranking loss after a relaunch:

broken URL mappings
missing or incorrect redirects
changed internal link graphs
lost structured data
canonical conflicts
hreflang errors (especially DE/EN)
rendering issues in Next.js / React
crawl budget collapse
index bloat or deindexing

Marketing-driven agencies treat migrations as "content launches".

Search engines treat them as system replacements. We operate at the system level.

Our Approach: Migration as Controlled Engineering

1.

Pre-Migration SEO & Architecture Audit

Before anything changes, we analyze:

current URL & ranking inventory
indexation state
internal link graph
structured data & entity IDs
traffic by intent cluster
crawl depth & canonical structure
rendering behavior (SSR / RSC / JS)

Nothing is migrated blindly.

2.

Migration Strategy & Mapping Blueprint

We design a migration blueprint, including:

1:1 URL mapping (old → new)
redirect strategy (301 only, no chains)
canonical preservation
hreflang continuity
sitemap transition plan
schema continuity with persistent @id
rollout strategy (phased vs atomic)

This blueprint is validated before launch.

3.

SEO-Safe Implementation (Next.js / React / CMS)

We handle migrations for:

Next.js (Pages & App Router)
React / SPA → SSR
WordPress → Headless / Next.js
Webflow → Custom stack
Monolith → modular architecture
Domain changes
Language architecture changes (DE/EN)

We ensure:

rendering parity
no metadata loss due to streaming
schema survives hydration
crawlable HTML output
4.

Launch Control & Index Transition

At launch we monitor:

Googlebot behavior
crawl rate & errors
index coverage
redirect accuracy
canonical resolution
schema validation
Core Web Vitals

Any anomaly is corrected immediately.

5.

Post-Migration Stabilization

After launch we provide:

ranking comparison (pre vs post)
traffic validation
index cleanup
sitemap optimization
crawl budget tuning
internal linking corrections

The goal is stability first, growth second.

FAQ

How do you prevent ranking loss during migrations?

We prevent ranking loss through systematic pre-migration audits, 1:1 URL mapping, proper 301 redirects (no chains), canonical preservation, schema continuity with persistent @id, and continuous monitoring during launch. We treat migrations as controlled system changes, not content updates.

Can you migrate Next.js sites without losing SEO?

Yes — we specialize in Next.js migrations (Pages Router → App Router, SSR/SSG transitions, RSC implementations). We ensure rendering parity, no metadata loss during streaming, schema survives hydration, and crawlable HTML output. We also handle React SPA → SSR migrations safely.

How do you handle multi-language migrations (DE/EN)?

We preserve hreflang continuity, maintain shared entity IDs across languages, ensure language-specific properties are correctly separated, and avoid duplicate entities per locale. This is one of the most common enterprise SEO mistakes we prevent.

What if my previous relaunch already failed?

We can recover from failed relaunches by auditing what went wrong, fixing broken redirects, restoring lost structured data, correcting canonical conflicts, and stabilizing the index. Recovery typically takes 4-8 weeks depending on the extent of damage.

How long does a safe SEO migration take?

A migration audit takes 1-2 weeks. Full migration (audit, blueprint, implementation, launch control, stabilization) typically takes 6-12 weeks depending on site complexity. We never rush migrations — stability is prioritized over speed.

We provide SEO migration and relaunch services for businesses across Germany. Our Berlin-based team specializes in zero-loss migrations, Next.js migrations, multi-language architecture changes, and enterprise SEO migrations in regulated environments.
