Domain Name
A human-readable address used to access websites on the internet.
A domain name is the address that people type into their browser to visit your website. For example, "google.com" or "amazon.com" are domain names.
Domain names consist of two main parts:
- Second-level domain (SLD): The unique name you choose (e.g., "google")
- Top-level domain (TLD): The extension (e.g., ".com", ".org", ".io")
Domain names are registered through domain registrars and must be renewed periodically (usually annually) to maintain ownership. Once registered, you have exclusive rights to that exact domain name for the registration period.
The Domain Hierarchy: Reading right to left, domains are organized hierarchically:
.com- Top-level domain (TLD)google- Second-level domain (your brand)wwwormail- Subdomain (you control these)
This means www.google.com and mail.google.com are both under the google.com domain.
Why It Matters
Your domain name is often the first impression of your business online. It affects brand perception, memorability, and can influence search engine rankings. Choosing the right domain is one of the most important decisions for your online presence.
Practical Example
If you're starting a bakery called 'Sweet Dreams,' you might register sweetdreamsbakery.com. Customers would type this address to find your website, see your menu, and place orders.
