To create a Blogger account, you need a Gmail account. After signing up for Gmail, you can access Blogger and create your blog by filling out basic information. It is recommended to purchase a custom domain name rather than using Blogger's free domain, as this will make your blog look more professional and allow easier migration if switching platforms later. To link a domain to Blogger, purchase a domain name from GoDaddy and configure DNS settings and CNAME records to point the domain to Blogger. Once complete, add the custom domain in Blogger settings. The process may take some time to propagate but then your blog can be accessed through the new domain URL.
