Bluehost is so renowned as a great hosting provider that WordPress.org itself recommends using it over its own platform. Not only that but Bluehost is actually WordPress.org’s number 1 choice. Strangely enough, the company barely mentions its own hosting services on its .org website, which is likely one of the reasons why WordPress isn’t very popular as a hosting provider. That’s just the tip of the iceberg, though.
Domain names can be used in a number of ways. Direct visitors to your website’s home page or use complementary domains to send them to specific areas of your website ( e.g. yourcompany.jobs for a careers page). Or, forward a custom domain to an existing social media account, like your Twitter profile or Periscope channel. With a domain name you can even set up custom email addresses like email@example.com, which can be used to conduct business or communicate with your followers. More.
