There are pros and cons to owning your own domain name for your blog. The pro side is that it gives you more control over your website and its appearance.
Owning a domain also gives you the added benefit of being able to redirect your visitors to your website if they happen to mistype your name or website address.
The con side of owning a domain is that it can be expensive. If you don’t have a specific name in mind, it can be difficult to find a domain that’s available and fits your blog’s theme.
Additionally, if you decide to sell your blog in the future, selling the domain name may not be an option.
