Understanding your options

What is a domain extension?

A domain extension is the ending that appears after the main name in a web address, such as .com, .co.uk or .org. It can help communicate the location, purpose or type of website.

The right extension depends on your audience, availability, branding and budget. You should also compare registration and renewal prices because costs can vary significantly between extensions.

  • .com

    General extensions

    Widely recognised extensions that can suit businesses, projects and websites intended for a broad audience.

  • .uk

    Country-code extensions

    Extensions linked to a particular country or territory, often used to show a clear geographic focus.

  • .org

    Purpose-led extensions

    Extensions commonly associated with organisations, communities or particular types of website.

  • .shop

    Specialist extensions

    Newer alternatives that can describe an industry, activity, location or purpose directly within the domain.

Before registering

Compare extensions carefully

Consider how the extension will look to visitors and what it may cost to keep before completing your registration.

  • Consider your audience Decide whether your website is intended for a local, national or international audience.
  • Check recognition Consider whether visitors will recognise and trust the extension when they see your web address.
  • Review eligibility rules Some country-code or restricted extensions may have registration requirements.
  • Compare renewal prices A low first-year price may be followed by a much higher annual renewal charge.
  • Check transfer conditions Review whether the extension can be transferred easily and what fees or waiting periods may apply.
  • Think about spelling Make sure the complete address is easy to say, remember and type without confusion.

Availability, pricing and registration rules vary by extension and registrar. Check the current terms and checkout information before completing a purchase.

Common questions

Domain extensions FAQ

Quick answers to common questions about choosing and registering a domain extension.

Does a domain extension affect search rankings?

An extension alone does not guarantee better rankings. Search visibility depends on factors such as the website’s content, relevance, quality and authority. A country-code extension may, however, help communicate that a website is intended for users in a particular location.

Can I change my domain extension later?

You cannot directly change the extension attached to an existing registration. You would normally need to register a new domain, move the website and email services, and redirect visitors from the old address where possible.
