While choosing a personal branding domain name you need to look for domains that can share your name and your passion. For example for a restaurant and car consultant, My Sandeep Verma, we came up with a domain name "CheersbySandy.com". This name reflects his interest in bartending and his popular name in the industry. This trick always works as it is almost impossible to get domain names with popular names. Therefore adding a keyword that reflects your expertise works.
