This is especially important for those in professions where it is likely that others might search for them online - health professionals and professors both fall into this category - or for job-seekers.

Most institutions, and especially most academic institutions, government agencies or hospitals, have social media guidelines for their staff and affiliates for any online identities that can be tied to them. If you are an employee of such an institution, please be sure to consult its social media guidelines. Typically, they will want you to avoid making controversial statements on a professional account (keep that for your personal account), be sure to use their name exactly in the style they prefer, and sometimes to avoid using your employment at all for certain types of accounts.
