If you've created a personal Facebook account, and wanted a business account, there may be questions about the difference.  Business accounts are designed for people who only want to use Facebook to administer Pages and run ad campaigns. For this reason, business accounts do not have the same features as personal accounts. Business accounts have limited access to information on Facebook-when using a business account, you can view all the Pages and Social Ads you own, but you will not be able to view profiles (timelines) or content owned by other people. Business accounts cannot be found in a search, and the owner of the account will not be able to send or receive friend requests.
