Short answer: register. The same German signal stack, in flawless English, still reads German to a US buyer. Words right. Frame wrong.
FRAME.
The translated US site usually pulls more traffic than the original German site, because Google sends more US sessions to a readable English page. That is the visible win. The invisible loss is that those US visitors scan, sort, and leave faster than the German visitors they replaced. The bounce rate climbs, average session time falls, and conversion drops. The translation made the wrong page reach more of the wrong people. Per the US Bureau of Economic Analysis FDI inflows 2025 and White & Case M&A Explorer 2026, US procurement is sorting foreign vendors earlier and the page-level sort is now the dominant filter.
What changes in a register rebuild: the hero stops opening with "Since 1957, we have engineered" and starts opening with "[Named US peer] reduced [metric] by [number] using [category]". The case studies stop opening with engineering achievements and start opening with customer name and quantified outcome. Pricing posture switches from Stundensatz to fixed-quote USD with US-style warranty language. ISO and CE certifications move out of the hero into a supporting trust block. SOC 2, HIPAA, FedRAMP, or the specific US procurement filter for the category enters the hero if relevant. The page changes shape.
A useful number: post-rebuild US conversion on the same product line typically lands in a 2-4x band versus the translated-only page, with the same paid traffic budget. The product did not change. The reader did not change. The page changed.
"Messaging that felt obvious suddenly felt flat. Pricing that seemed reasonable looked expensive."
