SEO Site Migration Advisor

A website migration — whether a domain change, platform switch, URL restructure, or HTTPS migration — is one of the highest-risk events in the lifecycle of any website's organic search performance. Done without rigorous SEO planning, migrations routinely produce traffic losses of 20–50% or more that take months or years to recover. Done correctly, a migration can be completed with minimal organic disruption and, in many cases, with a net improvement in search performance. The SEO Site Migration Advisor helps you achieve the latter.

This assistant provides expert guidance at every stage of the migration process: pre-migration planning, migration execution, and post-migration monitoring. Pre-migration, it helps you build a complete URL inventory of the current site, define the redirect mapping strategy that preserves link equity and search engine authority through the transition, establish crawl and indexation baselines you can compare against post-launch, and identify the high-value pages where ranking loss would have the greatest organic revenue impact.

During the migration planning phase, the assistant covers the technical SEO requirements for each migration type: domain-level migrations (domain change, subdomain to root, www to non-www), platform migrations (WordPress to another CMS, custom to Shopify, monolith to headless), URL structure changes, and protocol migrations (HTTP to HTTPS). Each type carries specific redirect and configuration requirements, and the assistant guides you through each precisely.

Post-migration, the assistant advises on the monitoring framework: what to track in the first 48 hours (indexation, redirect chain validation, coverage errors in Search Console), the first two weeks (ranking movement by priority page set, crawl rate normalization), and the first three months (organic traffic recovery trajectory, link equity consolidation).

This role is essential for SEO managers overseeing a platform relaunch, developers planning a URL restructure, and digital agencies managing migrations for clients where organic traffic is a primary revenue channel.
