Domain guide

Domain extensions: which one to pick

Updated Hostnali team

All domain guides

In short

The extension is the ending of a domain name, such as .co.tz, .tz or .com. Tanzanian businesses usually choose .co.tz; .tz is a shorter national option, .com suits an international audience, and .or.tz is often used by NGOs and associations.

Types of extension

  • Country code (ccTLD): for a country, such as .tz for Tanzania. Tanzania’s extensions are run by tzNIC, the Tanzania Network Information Centre.
  • Second-level country extensions: .co.tz, .or.tz and others: a category under .tz.
  • Generic (gTLD): .com, .net, .org and newer ones such as .africa, .online or .shop.

Our advice: a business selling in Tanzania should use .co.tz (or .tz) as its main address, and register the .com of the same name to protect it. Read .tz vs .co.tz for more.

Does the extension affect Google?

A country extension tells Google your site is for Tanzania, which helps you appear in Tanzanian searches. A .com can rank in Tanzania too, but needs other local signals. Either way, good content matters far more than the ending.

Global and African options

.africa is a pan-African extension for brands across the continent, and .org suits non-profits with an international audience. Search any name on domain registration to see which extensions are free.
