If you host your microblog with a paid Micro.blog plan, consider pointing a custom domain to it. This could be something like microblog.yourdomain.com. Mapping a custom domain to Micro.blog is included free, as long as you already have your domain registered. (Check out DNSimple if you’re looking to register a new domain.)
To get started, click on “Account” on Micro.blog, then scroll down to “Paid microblogs” and click “Edit Domains”. Next to the hostname you want to map a custom domain to, click the “Edit” button. Then fill in the hostname (e.g. microblog.yourdomain.com) that you’d like to use for your site.
After you’ve told Micro.blog about this custom domain, you still have to update your DNS record to point to Micro.blog. Instructions for this will vary depending on your registrar. Create a “CNAME” record wherever your domain is registered and use the value “pages.micro.blog”.
