Google search tips To get the most complete and accurate search results, search for things like your name, email address, home and work address, city, and phone number(s)—all written in a variety of ways. Also, put quotes around your search terms so Google will know to search for the exact phrase.

A quick way to clear those results is by making sure the profiles on those accounts are private. By making those profiles private, Google won't display them in search results. The caveat here is that if your profile was public and had shown up in search results before, it will continue to appear in Google searches.
