A domain name is how your website will be known online, no matter what type of website you’ll have. It is the unique address of your site on the internet and it will be yours as long as you continue paying the annual fee ($10 – $15 for the .com domain). Users who know your domain technically referred to as a URL (uniform resource locator) can simply type it in their browser’s address bar, and be taken there. Others will be able to discover your blog through search engines such as Google and Bing.
