We sell B2B software in three German-speaking markets โ Austria, Germany, and Switzerland โ and our agency had been running one English keyword list across all of them. Iurii's audit included proper per-market keyword research: actual search demand in DE-AT, DE-DE, and DE-CH, plus the technical changes we needed (hreflang, regional canonicals, locale-specific schema). The keyword findings alone reshaped our content plan. We've already shifted three landing pages and are seeing impressions climb in Search Console.

Iurii built our entire B2B platform from scratch in a remarkably short time โ a fully multilingual webshop covering 32 European markets in 28 languages, with automated VAT calculation, VIES validation, Stripe payments across 6 methods including SEPA and bank transfers, server-generated PDF invoices, and Notion as our CRM. Everything was integrated and working end-to-end, not just a prototype. As someone responsible for both sales and operations, I especially valued that he understood the business side โ compliance requirements, B2B buyer expectations, different payment preferences across markets. He asked the right questions upfront, kept things transparent throughout, and delivered without dragging it out. Highly recommend.

We were ranking in Dutch but completely invisible in Belgium and Germany โ same products, same pages, just translated. Iurii's audit found three things in 48 hours: hreflang tags pointing at the wrong canonicals, a sitemap that listed only the Dutch URLs, and product schema that didn't carry over to localized pages. The report was specific enough that our dev team fixed all of it in a week. Traffic from non-Dutch markets doubled the next month.
