International SEO: Zero to 1,400 Organic Sessions in Three MonthsSector: Maritime Tech

Engagement: Technical SEO + Content Localization

The Situation

The client managed ships for companies across Asia, Europe, and the Middle East. They had content in English, Japanese, and Chinese. All of it sat on one domain. The pages were indexed. But Japanese buyers were landing on English pages. Chinese audiences were not finding the product at all. Organic traffic across all localized pages: zero.

This was not a content problem. The content was fine. It was a communication failure between the site and Google. Google had no way to tell which page was meant for which audience. So it treated the Japanese and Chinese pages as copies of the English site. Copies do not rank.

What I Diagnosed

Three problems were visible immediately.

Google had no hreflang tags to work with. Without them, it cannot route the right user to the right page. The Japanese and Chinese pages were cannibalizing the English site instead of serving separate audiences.

The localized pages were translations, not localizations. Japanese maritime buyers search differently. They use different terminology. A word-for-word translation targets English search behavior, not Japanese.

There were no regional backlinks. Subdirectories do not carry strong geographic signals on their own. Without links from Japanese and Chinese industry sources, Google had no reason to trust those pages for regional audiences.

What I Did

I implemented hreflang tags across all three language versions. Every page now tells Google which language it is for and where the alternate versions live. Every version references itself and the others. One missing direction breaks the whole setup. We got them all right.

I fixed URL consistency across all subdirectories. Trailing slash mismatches were breaking the tag implementation silently.

I rewrote the core service pages for Japanese and Chinese audiences. Not translated. Rewritten for how buyers in those markets describe their problems. Different H1s, different meta tags, different content priorities.

I built a content layer around regulatory and operational news relevant to each market. This content got picked up by regional maritime media. Those links gave Google the geographic trust signals the subdirectory structure could not carry on its own.

What Changed

Zero organic sessions on localized pages at the start. After three months: 1,400 monthly sessions on the English site, 272 combined across Japanese and Chinese pages. Japanese moved faster because the content investment was deeper. Chinese lagged about six weeks, which matches how long Google takes to process new signals in that index.

The right message only works if the right person finds it. This was a positioning problem dressed as a technical one.
