1. Choose a unique name
If you are marketing yourself, ideally you’ll be able to use your first and last names (johnsmith.com or janesmith.com). Even if you aren’t marketing yourself, it’s not a bad idea to register your name as a domain now, in case you want to use it in the future. If you are marketing your business, you should see if your business name (yourbusiness.com) is available.
Using a search engine like Google, search for your proposed blog or website name. Does your search show any sites with similar domain names? If it does, try a different name. Giving your website a name that’s similar to other existing sites is the first step to failure. Also, don’t choose names that are plural or misspelled versions of existing sites.
