SEO: does the extension matter?

Short answer: not for rankings. Content, links and site speed decide where you rank; the extension mostly affects trust, memorability and which country search engines assume you serve.

.com

A generic extension: no ranking advantage or penalty on its own. Search engines rank the content and the links, and let you target any country.

.biz

A generic extension: no ranking advantage or penalty on its own. Search engines rank the content and the links, and let you target any country.

Myth check: no extension gets a hidden ranking bonus, and keyword extensions (like .shop or .tech) do not rank better for that keyword. Switching an established site to a new extension costs time while search engines re-learn it, so choose well up front.

Our verdict, by kind of site

Based on what each extension signals to visitors and its three-year cost at today’s prices.

  • Startup or SaaS product.com.com reads as a product brand to investors and users; .biz is a weaker match for a startup name.
  • Local business.com.com is what local customers expect; .biz reads as less local.
  • Tech or developer project.com.com signals a technical product or team at a glance; .biz is less specific.
  • Online shop.com.com tells shoppers they can buy here or is the address they trust most; .biz fits a shop less naturally.
  • Non-profit or community.com.com is the better fit for an organisation or community; .biz reads as more commercial or technical.
  • Personal brand or portfolio.com.com reads naturally as a personal name or portfolio; .biz is less personal.
