The information in your profile header or bio is an important argument for a potential subscriber. This is your business card. Use key search terms to make you easier to find, spell out your USP, structure all the information about the brand, break it into blocks and highlight the emoji.
If you promote a commercial account, you should try to include keywords in username, then for a personal blog to do exactly the opposite, such words will only repel. As an option, use the first and last name.
