.biz
The .biz domain launched in 2001 as one of the first new gTLDs, now operated by GoDaddy Registry (formerly Neustar). Intended as a business-focused alternative to .com, it has seen moderate adoption. While it hasn’t achieved the ubiquity its creators envisioned, .biz remains a viable option for business websites, particularly when preferred .com names are unavailable. It’s recognized by search engines as a legitimate extension and is used by various businesses worldwide. The extension’s straightforward meaning makes it immediately clear that a site is business-related.
