My understanding of it is this Bob.
To set up a FB business page correctly, you first need a personal profile. (Some people set up a personal account but name it after their business. This is incorrect and FB often ban these type of accounts) using your personal page you need to create a page "xyz window cleaning". You can then switch between acting as your own personal profile and "xyz window cleaning". You can also use your own personal page to share/link/spam items from your business page to get more exposure.
For example, post/upload some pictures of a conservatory clean before and after to your business page, then switch to your personal page and like and share it, this will make it show up on all of your personal friends newsfeeds.
Also when asking for likes from others on this forum, you need likes from their personal accounts and not their business accounts because they will not show as a "like" (unless they set their own business page up incorrectly)
