We’re excited to announce a powerful new enhancement to BuiltWith: Inferred Language Tracking. Traditionally, identifying the language of a website has relied on explicit HTML indicators like the html lang="..." tag. However, many sites—especially generic TLDs like .com—don’t specify their language at all. With our new inferred language system, BuiltWith now intelligently analyzes the actual text content of a webpage to determine its primary written language. This includes recognizing character sets, word patterns, and syntax across global languages—even when the site itself gives no direct clues.

This update means you can now uncover websites written in languages such as French, Japanese, German, or Arabic, even on domains that appear completely neutral. Whether you're running localized campaigns, researching market trends by language, or seeking non-English opportunities within .com domains, our inferred language tracking gives you deeper visibility into the true linguistic nature of the web. It’s just another way we’re helping you see the internet more clearly.
