You can search Facebook without an account but some of your search will have limited returns. First, you can use Facebook’s own Facebook Directory or Facebook People Search facilities to search for information within Facebook. Outside of these facilities, you can use social search engines such as Pipl and Social Searcher. Then, there is the usual standby of using Google Search to search a website by using the standard search string of site:sitename.com query. As well, the steps above explain how to look at a Facebook profile without signing up, but realize you won’t be able to see as much as someone signed in.
