The visibility took years to build and one release to put at risk.
An industrial SEO migration carried out so that a replatform, redesign, domain change or site consolidation keeps the rankings, the document URLs and the product visibility the estate has accumulated. Planned before the build starts, verified before launch, and monitored afterwards until crawl behaviour settles.
A page with modest sessions can hold the specification a sales engineer sends to every prospect, and a document with no inbound links can be the reason an installer returns. Deciding what to retain means combining analytics and Search Console data with what the commercial team knows about how the site is used in practice.
On industrial estates, PDFs frequently attract more external links than pages do. Distributor sites, trade associations, forums and specification portals link straight to a manual or a datasheet and will never update those links. A move that changes document paths without a per-file mapping discards that permanently, which is the most common cause of a lasting drop.
Blanket rules are where migrations go wrong. Redirecting a retired section to its parent, or to the homepage, tells search engines the content is gone rather than moved. Each retained URL is mapped to the closest equivalent destination, and where no equivalent exists that decision is recorded deliberately rather than left to a fallback.
Structured data, hreflang and region targeting, canonical rules, internal linking, pagination and faceted-navigation handling, XML sitemaps and robots directives all move with the estate. Each is verified on staging before release, because a robots file or a noindex header carried over from the staging environment is a routine and costly launch error.
Redirects are tested as a set against the full inventory rather than sampled. We crawl the staging build, compare it against the live estate, and check that every mapped URL resolves in a single hop to a page returning 200, with the intended canonical, title, heading structure and indexability.
An inventory and value assessment, a page-level and file-level redirect map, pre-launch verification, launch-day checks and post-launch monitoring until crawl behaviour settles. See industrial website migration for the wider platform move and technical SEO audit for the standing health check.
Code Industrial is the industrial B2B practice of Code Barcelona, an agency building corporate websites and digital platforms since 2015. The same strategy, design and engineering team works on every industrial project, from the first scoping session through to life after launch.
What the estate has earned differs by sector. An industrial SEO migration is planned around it.
What manufacturers and distributors ask before a structural change to the estate.
A controlled migration protects the signals that produce them: each retained URL mapped to a specific destination, redirects tested as a complete set before release, and crawl behaviour monitored afterwards. Some movement while search engines reprocess the estate is expected and settles. Persistent losses usually trace back to incomplete mapping or to a document layer that was not inventoried.
Before the new structure is fixed. Once the information architecture is agreed and built, the mapping exercise can only react to it, and the opportunity to influence URL patterns, consolidation decisions and hierarchy has passed. Starting during architecture means retention decisions inform the design rather than being retrofitted to it.
Plan on keeping them indefinitely for anything that carried traffic, links or a document reference. Search engines consolidate signals within months, but industrial URLs are shared internally, printed in documentation and saved by customers, so a redirect that costs little to keep can still be resolving a real request years later. We hand over the map so it can be maintained rather than lost.
They are inventoried and mapped with the same care as pages. On industrial estates documents frequently hold more external links than pages do, and those links are held by distributors and trade sites that will not update them. Wherever an external reference points directly at a file, we preserve the path or redirect it individually rather than folding it into a section rule.
It can be done together, and after a rebrand or a corporate restructure it sometimes has to be. Combining them concentrates the disruption into one event, at the cost of making diagnosis harder if visibility moves unexpectedly. Where there is a choice, separating the platform move from the domain move lets each be verified independently.
Often, and the first step is establishing what happened rather than assuming. We crawl the current estate, compare it against an archived version of the previous one, and look for URLs that now return 404, redirect chains, blanket redirects to section pages, lost hreflang and missing canonical rules. Recovery depends on how much of the previous structure can still be reconstructed.
Language and region targeting is mapped as its own layer. Every language variant of a retained URL needs its own destination, and the hreflang relationships have to be re-declared against the new structure and verified as a set, since a partially declared cluster is treated as unreliable. See hreflang for industrial B2B websites.
Access to analytics and Search Console, a crawl or export of the current estate, the staging environment ahead of release, and server access or a route to whoever controls the redirect layer. Beyond that, someone from the commercial side who can say which pages and documents matter in practice, since that knowledge rarely appears in analytics.
An SEO migration is usually part of one of these.
