BGN/EUR converter for Bulgaria's euro adoption

Hacker News

Built this as a side project ahead of Bulgaria joining the eurozone (Jan 1, 2026). A few things I tried that seemed to work: - Launched ~2 months before the fixed rate announcement so Google had time to index - The domain "levaevro.com" is a transliteration of "лева в евро" (leva in euro) – exact-match domains still work surprisingly well in smaller language markets - Instead of canonicalizing all query param URLs to the homepage, I submitted 52 parameterized URLs to a custom sitemap (?amount=100&from=BGN, ?amount=500&from=BGN, etc.) – each one targets a specific search query like "100 лева в евро". Zero extra dev work, same template. - Added a llms-sitemap.xml for AI crawlers (ChatGPT, Perplexity) alongside the standard sitemap The fixed exchange rate (1 EUR = 1.95583 BGN) is set by EU Council regulation and will never change, so the tool stays accurate forever with no maintenance. Happy to share more details about the SEO approach or the technical setup.
