Each Twitter account has a profile page containing a biography section into which the account's owner can place a brief descriptive blurb. Use the Search Twitter box on any page of the Twitter website to search for the user whose bio you want to view or click the name of any user displayed on your Twitter home screen.
Sign in to your Twitter account and click the Home tab if your home timeline doesn't open automatically.
Click the Search Twitter field, enter the name or Twitter handle of the person or account you want to view and then click the account on the search results. You can also search by keywords.
Bypass the search function by clicking on the name of any user you see on Twitter to open a profile. In most cases, this opens the profile summary; in some cases it opens the full profile. Both display the user's bio.
Locate the account's bio on the left of the full profile page or at the top of the summary profile under the user's name.
If a Twitter account is set to private, you won't be able to view the user's bio unless the user approves you as a follower.
