Chose above as preferred domain?
But canonical URL is www.kamal.com.bd or more specifically https://www.kamal.com.bd .
Interestingly kamal.com.bd or http://kamal.com.bd naked domain automatically uses HTTP 301 redirect to canonical URL i.e. www version of kamal.com.bd or www.kamal.com.bd .
✓ URL shortener is now a very popular trend.
✓ non-www has advantage of less keystrokes typing and more memorable. Thus, URL recall will be easier.
The debate will continue unless research findings are made available for decision making!
