Go to www.twitter.com/signup
Fill out the form with name, email address or phone number, and password. You’ll select your username at the next step.
Once you’re logged in, you will have the opportunity to select a username. A few things to consider when selecting this username or ‘handle’:
Keep it short. You only have 140 characters per ‘tweet’ (i.e. message). Keep your username short so it does not take up your character account. Usernames are capped at 15 characters.
Make it relevant. Do you want your username to be your name? Your company name? And if so, is it available? If it is not, try adding an underscore ( _ ) or hyphen ( - ) to get the name you want. Ex: @ashleygaudiano is not available. Try ashley_gaudiano or agaudiano
Avoid Numbers. Numbers on the end of a Twitter username tend to look like spam. If possible, avoid using them in your username.
Add a profile photo & a cover photo. A profile photo should be of you. Your cover photo leaves room for more expression. If you choose not to add a header photo, Twitter will automatically keep this a solid color. This is a great cheat sheet for sizing your social media images. Image size matters!
Update your profile. This includes name, bio, location, and website. Your bio should give people some insight into who you are, what you do, what they can expect from your tweets. You can include hashtags, though this is not necessary.
