Here's a common scenario: You have a client who you know would benefit from a Facebook Page but the client isn't convinced.
First of all you have to demonstrate how you would plan to limit their risks, then you have to underline that an active social media presence can help inspire brand loyalty. Other clients may worry about the money needed to maintain a Facebook page, so be sure to mention a budget that includes operating costs, and advertising.
