To make facebook work you need to keep updating your page daily - and with interesting things, not just about window cleaning
for example the other half has been doing 'live chat' for a large climbing frame company - they have over 25k followers on their page yet not a single sale comes from FB - why? - the page is updated sporadically and only/solely with climbing frame photos. its boring and nothing on there gets picked up by google.
Post daily - make it funky, find stories and fun news to add - all this will help promote your page
