Facebook is always a great start for small businesses, but your marketing should not stop there. We like to think of your web page like your classic brick-and-mortar business where it has an address and if people were to look it up in the Yellow Pages (a.k.a. Google), they would find it. Facebook is more where the employees/owners hang out and talk with their friends about the business. It limits the business to their friends and those that hang out there(a.k.a. Facebook Members).
Building creative and engaging content on a web page makes your page more noticeable on search engines and therefore brings more traffic to your site. Having a domain name gives you a specific address and builds value to the business that you may pass on later.
There are all kinds of starving writers or students you can pass this job of writing your blog to. This is called "ghostwriting."Wikipedia says a ghostwriter is a writer who writes books, articles, stories, reports, or other texts that are officially credited to another person. Just make sure when you choose a writer to represent you on your page they know your goals with the site and with the business.They should want to listen to your thoughts before they start writing.
