In a move, things rarely go wrong in the design, but almost always in the addresses. A product that used to live at /product/kamado-xl and now at /kamado-xl returns an error page without a redirect, and its position in Google starts over. That is why we first fetched the old shop's sitemaps, in every language, and gave every address a destination.
Blog articles were not migrated as a wall of text, but rebuilt from blocks: a short answer at the top, sections with subheadings and an FAQ. That way a visitor reads faster what they came for, and search engines and AI assistants understand better what the page is about.
The design is not a fixed template, but a theme of its own on Neuramerce. Header, product page, checkout and account follow the Nomad Fire house style, while the parts underneath, such as search, cart and payments, are the same as for every other shop on the platform.
The design changes, the addresses stay findable.
