Did you define who your ideal prospects are and where they hang out online to discuss the issues you solve and or go to for sourcing what you offer?
Do that first before you try and manage your facebook and or twitter social media initiatives. What you say and do necessitates knowing, not guessing what ideal prospects care about and then how to use the correct social media to reach them re their stated issues and offer your solutions, products. services in a way that dos so.
Why spend time on either if your ideal target market and prospects are not there or dont go there to discuss the issues your products, services can resolve nor do they look for products or solutions via those tools.
Please dont assume you need a presence on facebook and or Twitter. First validate its where your ideal target audience actually goes or hangs out online. Then validate how well you can actually use the site to manage contact reach, influence opinion and prospect action.
Example, B2B's dont participate in Facebook nor do they go there to source or discuss business issues. See what I mean.
