Remember that scene in the movie, The Wizard of Oz, where the famous wizard was caught as a phony, saying "Pay no attention to the man behind the curtain"?
Well, think of Oz when you select a firm or indicidual to market for your company. What are they really about? For instance, there are all kinds of firms in the Green Bay area who proclaim to know web development and social media optimization. Looking behind their curtains - their own websites for example - we find they can't even link to pages correctly or fold in social media appropriately.
So choose wisely when you choose to partner with a marketing firm. Make sure what they say can be backed up with real work.
