Vaden Original: International SEO Case Study in 9 Languages, 2 Domains

The Challenge

One catalog, nine languages, two domains that must not compete. Vaden manufactures air brake and pneumatic components for commercial vehicles and has exported to more than 110 countries to date. We first built vaden.com.tr for the Turkish market. For the global market, Vaden then needed Vaden Original: the same catalog of about 12,500 products in eight more languages, on a separate .com domain. That made it an international, multilingual SEO problem before it was a design problem. Search engines had to understand that the two domains carry one catalog, not two duplicate ones; every visitor had to land on their own language; and each product had to exist as a real, indexable page in every language. The product data already lived in Vaden's ERP, so the site had to take its content from there instead of from manual entry.

The Solution

We launched vadenoriginal.com alongside vaden.com.tr. Turkish stays on vaden.com.tr; English, German, Spanish, French, Portuguese, Russian, Polish and Italian are served from vadenoriginal.com, and the two domains share one hreflang cluster.

• Two domains, nine languages: every language has its own URL paths, such as /en/products, /de/produkte and /ru/produkty.
• Reciprocal hreflang across two domains: every page lists its language versions on both domains, x-default points to the English version, and each page names itself as canonical on its own domain, so search engines see one catalog rather than two.
• Product pages in nine languages: every product is published in all nine languages with its own localized title and address, more than 100,000 product pages in total.
• ERP integration: product data comes from Vaden's ERP, so the catalog stays current across all language versions.
• Search by part number: visitors can search by Vaden code, OEM number, product name, brand or model in all nine languages.
• Technical SEO and structured data: product and category pages carry schema.org structured data, and the site is built so that search engines crawl and index the right page in every language on both domains.

The Results

According to Ahrefs data:

• A health score of 99/100 ("Excellent") in Ahrefs Site Audit.
• A 5.5% visibility share for vaden.com.tr in early 2025 across the tracked keywords in Ahrefs Rank Tracker (week of 24 February to 2 March 2025), against at most 0.3% for each of the 10 tracked competitors.
• vadenoriginal.com ranks in 57 countries (September 2026), with 573 organic keywords in total, 195 of them in the top three positions.
• 203 keywords in the United States, 54 of them in the top three, followed by Brazil (56), Mexico (55), Peru (38), Russia (34), Poland (29) and Spain (24).
• vaden.com.tr ranks for 762 organic keywords, 193 of them in the top three.

The country list follows the languages: the Spanish version ranks in Mexico, Peru and Spain, the Portuguese version in Brazil, and the Russian and Polish versions in their own markets, while in the United States 160 of the 203 keywords land on the English version and 17 on the Spanish one.

We explain the general hreflang and canonical rules for this kind of setup in our guide to multilingual SEO across two domains. The Vaden project is a concrete example of international SEO built into the platform itself: nine languages, two domains and one hreflang cluster.
