Move platforms, keep the rankings.
A bad migration deletes years of equity in one weekend. We map every legacy URL to its new destination as a 301, hold canonicals to a single source of truth, and run a monitored cutover with rollback ready so the new site launches with rankings intact.
Redirect mapping
Every legacy URL gets a 301 to its closest new equivalent, validated against logs so high-traffic and high-backlink pages cannot be missed.
Template-level SEO
Canonicals, metadata, schema, and internal links survive the template rebuild because they are spec'd before the design lands, not after.
Monitored launch
Pre-launch staging crawl, DNS flip, post-launch coverage check, and a rollback path. Search Console and log files watched in real time.
