When setting up a website, one important decision is whether to use a "www" subdomain:

www.example.com

or a non-www domain:

example.com

While both options work, maintaining consistency is key for SEO and user experience.

Why Choose One?

• Branding & Consistency: Using a single domain format ensures uniformity across links and search engine indexing.
  
• SEO Considerations: Avoiding duplicate content issues improves search rankings.
  
• Technical Reasons: Some hosting setups benefit from www domains for better performance and scalability.
  

Also Pressing Ctrl + Enter in most browsers automatically adds "www." to the beginning and ".com" to the end of the text entered in the address bar, making it a quick way to access common domains and many prefer this shortcut to open a url like this. This is something to be considered as well.

Personally I like to use non WWW url and just for consistency I force redirect all the traffic to non WWW url by changing the htaccess rules, but that’s my personal preference.

Which format do you prefer, and why?
