Does advertising on Facebook work?
Yes it does, Make a page for the business/product you want to advertise, start by making an announcement to friends and family to head over and like the page you just created. The more likes you get the more relevant your page will look.
Next Join groups on Facebook, there are so many groups on Facebook such as “business classifieds” or “small business in _____ town )
Post a few status updates weekly on your page to make people aware that it is a monitored page. List any promotions, pricing, common questions on the page.
Last but not least, Network with other business owners.
