There is no way to truly measure ROI on Social Media please stop asking!
Yes there is a value in Social Media, will you find a way to measure it? No, not from someone else. You will have to find what is valuable to you and your organization and look to increase that point with social media. No one else can create this formula for you. Oh, and one more thing. Don’t try to tie social media efforts directly to revenue or you will end up like this. That is all!
