What does a .bio domain mean?
.bio is commonly used by people and businesses in biology, biotech, wellness, and personal branding. It originally pointed to “biography,” but today it usually signals a bio-related site or profile.
Is a .bio domain trusted?
Yes. .bio is a valid top-level domain with an official registry, so it works normally in browsers, email, and search engines. Trust depends more on your website content and security than on the extension itself.
Is a .bio a good domain?
Yes, if your site is about biology, biotechnology, health, or a personal bio. Search engines treat it like any other TLD, so relevance and content matter more than the extension.
